PRECAUTIONS
[YD (WITH EURO-OBD)]
PFP:00001
PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) AIR BAG and SEAT
BELT PRE-TENSIONER

EBS013IW

The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

On Board Diagnostic (OBD) System of Engine

EBS013IX

The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:

Be sure to turn the ignition switch OFF and disconnect the battery ground cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MI to light up.

Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

Certain systems and components, especially those related to OBD, may use a new style slidelocking type harness connector. For description and how to disconnect, refer to PG-108, "HARNESS CONNECTOR" .

Be sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.

Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel system, etc.

Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.

Precautions

EBS013IY

Always use a 12 volt battery as power source.

Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect battery
ground cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
Before removing parts, turn ignition switch OFF and then
disconnect battery ground cable.

C
MBIB0625E

When connecting ECM harness connector, fasten it

securely with levers as far as they will go as shown in the
figure.

G
MBIB0145E

When connecting or disconnecting pin connectors into or

from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to IC's.
Keep engine control system harness at least 10cm (4 in)
away from adjacent harness, to prevent engine control system malfunctions due to receiving external noise, degraded
operation of IC's, etc.
Keep engine control system parts and harness dry.
Before replacing ECM, perform ECM Terminals and Reference Value inspection and make sure ECM functions properly. Refer to EC-57, "ECM Terminals And Reference Value"
.
Handle mass air flow sensor carefully to avoid damage.
Do not disassemble mass air flow sensor.
Do not clean mass air flow sensor with any type of detergent.
Even a slight leak in the air intake system can cause serious incidents.
Do not shock or jar the camshaft position sensor, crankshaft position sensor.

Fuel Injection Control System

EBS013J5

SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.

When the ECM receives a start signal from the ignition switch, the
ECM adapts the fuel injection system for the start control. The
amount of fuel injected at engine starting is a preset program value
in the ECM. The program is determined by the engine speed, engine
coolant temperature and fuel rail pressure.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches the specific value, and shifts the control to the normal or idle
control.

When the ECM determines that the engine speed is at idle, the fuel injection system is adapted for the idle
control. The ECM regulates the amount of fuel injected corresponding to changes in load applied to the engine
to keep engine speed constant. The ECM also provides the system with a fast idle control in response to the
engine coolant temperature signal.

accelerator pedal position and fuel rail pressure sensor detects fuel
rail pressure. These sensors send signals to the ECM.
The fuel injection data, predetermined by correlation between various engine speeds, accelerator pedal positions and fuel rail pressure are stored in the ECM memory, forming a map. The ECM
determines the optimal amount of fuel to be injected using the sensor signals in comparison with the map.

CAN Communication

EBS013JA

SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

EBS013JB

DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.

EC

AIR BLEEDING
Pump the priming pump to bleed air.

When air is bled completely, the pumping of the priming pump

suddenly becomes heavy. Stop the operation at that time.

If it is difficult to bleed air by the pumping of the priming pump

(the pumping of the priming pump does not become heavy), disconnect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.

Start engine and let it idle for at least 1 minute after performing
air bleeding.

Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.
It is not necessary to disconnect the fuel hose.
Using a tool such as a pliers, loosen the water draining cock at
the bottom of the fuel filter.
Loosening drain cock four to five turns causes water to
start draining.
Do not remove drain cock by loosening it excessively.
If water dose not drain properly, move the priming up and down.
CAUTION:
When the water is drained, the fuel is also drained. Use a
pan, etc. to avoid fuel adherence to the rubber parts such as
the engine mount insulator.
Do not over-tighten the water draining cock. This will damSMA825B
age the cock thread, resulting in water or fuel leak.
Bleed air of the fuel filter. Refer to EC-29, "AIR BLEEDING" .
Start the engine.

Fuel Pump Learning Value Clearing

EBS013JC

DESCRIPTION
In order to always keep optimum fuel pressure in fuel rail, the ECM controls fuel pump in high precision with
monitoring the signal of fuel rail pressure sensor.
Accordingly, the ECM always learns characteristic value of fuel pump. Fuel Pump Learning Value Clearing is
an operating to clear the value of the fuel pump learning.
It must be performed after the fuel pump is changed. When the ECM is replaced with brand new one, the Fuel
Pump Learning Value Clearing is not necessary to be performed. If the ECM to be replaced has the possibility
of learning the characteristic value of fuel pump, the Fuel Pump Learning Value Clearing is necessary to be
performed after the ECM has been replaced.

OPERATION PROCEDURE
NOTE:
Remove fuel pump without starting engine after performing Fuel Pump Learning Value Clearing.

Three Trip Detection Logic and One Trip Detection Logic

EBS013JE

On board diagnosis (OBD) system of this vehicle has Three Trip Detection Logic and One Trip Detection
Logic. For which logic each self-diagnosis corresponds with, refer to EC-11, "INDEX FOR DTC" .
Trip of Three Trip Detection Logic means a driving mode in which the self-diagnosis is performed while
driving.

THREE TRIP DETECTION LOGIC

When a malfunction is detected for the first time, 1st trip DTC is stored in the ECM memory. MI does not illuminate at this stage. <1st trip>
When the same malfunction is detected again during the next driving, 2nd trip DTC is stored in the ECM memory and 1st trip DTC is cleared from the ECM memory. MI does not illuminate at this stage. <2nd trip>
When the same malfunction is detected again at the third driving, DTC and Freeze Frame Data are stored in
the ECM memory and 2nd trip DTC is cleared from the ECM memory. MI illuminates at the same time when
DTC is stored. <3rd trip>
In other words, DTC and Freeze Frame Data are stored and MI illuminates when the same malfunction occurs
in 3 consecutive trips.
This is called Three Trip Detection Logic.

ONE TRIP DETECTION LOGIC

When a malfunction is detected for the first time, DTC and Freeze Frame Data are stored in the ECM memory
and MI lights up. This is called One Trip Detection Logic. Some self-diagnoses will not illuminate MI when
DTC is stored. (Refer to EC-31, "Emission-related Diagnostic Information" .) 1st/2nd trip DTC is not stored for
one trip detection logic.

NATS MALFUNTION

*1: 1st trip DTC No. and 2nd trip DTC No. are the same as DTC No.
*2: This number is prescribed by ISO 15031-6.

DTC AND 1ST/2ND TRIP DTC

The number of 1st/2nd trip DTC is the same as the number of DTC.
When a malfunction is detected during 1st trip, 1st trip DTC is stored in the ECM memory. MI does not illuminate at this time. When the same malfunction is detected in the next trip (2nd trip), 2nd trip DTC is stored in the
ECM memory and 1st trip DTC is cleared from the ECM memory. MI does not illuminate at this time. In addition, DTC is stored in the ECM memory and Mi lights up when the same malfunction is detected during the following consecutive trip (3rd trip).
The procedure for erasing DTC, 1st trip DTC, and 2nd trip DTC from the ECM memory is described in EC-34,
"HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
For malfunctions in which 1st/2nd trip DTC are displayed, Refer to EC-31, "Emission-related Diagnostic Information" .
1st/2nd trip DTC is specified in Mode 7 of ISO15031-5. 1st/2nd trip DTC detection occurs without lighting up
MI and therefore does not warn the driver of a malfunction.

EC-33

EC

ON BOARD DIAGNOSTIC (OBD) SYSTEM

[YD (WITH EURO-OBD)]
When 1st/2nd trip DTC is detected, check, print out or write down, and erase 1st/2nd trip DTC as specified
with step II of Work Flow, refer to EC-41, "WORK FLOW" . Then perform DTC Confirmation Procedure or
Overall Function Check to try to duplicate the malfunction. If the malfunction is duplicated, it is necessary to
investigate the cause again.

How to Read DTC and 1st/2nd Trip DTC

DTC and 1st/2nd trip DTC can be read by the following procedures.
With CONSULT-II
With GST
ONSULT-II or GST (Generic Scan Tool): Examples: P0117, P0335, P1260, etc.
These numbers are prescribed by ISO 15031-6.
(CONSULT-II also displays the malfunctioning parts and systems.)
A sample of CONSULT-II display for DTC and 1st/2nd trip DTC is
shown in the figure. DTC and 1st/2nd trip DTC are displayed in the
SELF-DIAG RESULTS mode of CONSULT-II.
TIME data shows how many times the vehicle was driven after the
last detection of DTC or 1st/2nd trip DTC. When DTC or 1st/2nd trip
DTC has been detected currently, TIME becomes 0.

CONSULT-II displays for DTC and 1st/2nd trip DTC become the
same.

The output of a DTC indicates a malfunction. However, GST

does not indicate whether the malfunction is still occurring or
has occurred in the past and has returned to normal. CONSULTII can identify the malfunction status. Therefore the use of CONSULT-II (If available) is recommended.

PBIB2022E

FREEZE FRAME DATA

ECM records driving conditions such as calculated load value, engine coolant temperature, engine speed,
vehicle speed, and intake manifold pressure at the moment a malfunction is detected.
The data stored together with DTC is called Freeze Frame Data, and is displayed on CONSULT-II or GST.
When 1st/2nd trip DTC is detected, Freeze Frame Data is not recorded.
Only a set of Freeze Frame Data can be stored in the ECM memory. When ECM records Freeze Frame Data,
and another Freeze Frame Data is generated after that, the first (original) Freeze Frame Data is not updated in
ECM and it remains.
When the DTC is erased from ECM memory, Freeze Frame Data is erased with DTC. The procedure for erasing DTC is described in EC-34, "How to Erase DTC" .

HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION

How to Erase DTC
With CONSULT-II
The emission related diagnostic information in the ECM can be erased by selecting ERASE in the SELFDIAG RESULTS mode with CONSULT-II.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2. Touch ENGINE.
3. Touch SELF-DIAG RESULTS.

EC-34

With GST
The emission related diagnostic information in the ECM can be erased by selecting MODE 4 with GST.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2. Select MODE 4 with GST (Generic Scan Tool).

If the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.

The following data are cleared when the ECM memory is erased.

Diagnostic trouble codes

1st trip diagnostic trouble codes

2nd trip diagnostic trouble codes

Freeze frame data

Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures.

NATS (Nissan Anti-theft System)

EBS013JG

If the security indicator lights up with the ignition switch in

the ON position or "NATS MALFUNCTION" is displayed on
"SELF-DIAG RESULTS" screen, perform self-diagnostic
results mode with CONSULT-II using NATS program card.
Refer to NATS (Nissan Anti-Theft System) in BL section.
Confirm no self-diagnostic results of NATS is displayed
before touching "ERASE" in "SELF-DAIG RESULTS" mode
with CONSULT-II.
When replacing ECM, initialization of NATS system and registration of all NATS ignition key IDs must be carried out
SEF543X
with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedure of NATS initialization and NATS ignition key ID registration, refer to CONSULT-II operation manual, NATS.

TROUBLE DIAGNOSIS
Trouble Diagnosis Introduction

PFP:00004
EBS013JJ

INTRODUCTION
The engine has an ECM to control major systems such as fuel injection control, fuel injection timing control, glow control system, etc.
The ECM accepts input signals from sensors and instantly actuators.
It is essential that both input and output signals are proper and stable. At the same time, it is important that there are no malfunctions
such as vacuum leaks, or other malfunctions with the engine.

MEF036D

It is much more difficult to diagnose a malfunction that occurs intermittently rather than continuously. Most intermittent malfunctions are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replacement of good parts.

SEF233G

A visual check only may not find the cause of the incidents. A road
test with CONSULT-II or a circuit tester connected should be performed. Follow the EC-41, "WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer can supply good information about such incidents, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A Diagnostic Worksheet like the example
on next page should be used.
Start your diagnosis by looking for conventional incidents first. This
will help troubleshoot driveability incidents on an electronically controlled engine vehicle.

[YD (WITH EURO-OBD)]
Description for Work Flow
STEP

DESCRIPTION

STEP I

Get detailed information about the conditions and the environment when the incident/symptom occurred using the
EC-42, "DIAGNOSTIC WORK SHEET" .

STEP II

Before confirming the concern, check and write down (print out using CONSULT-II or GST) the (1st/2nd trip) DTC and
the freeze frame data (When 1st/2nd trip DTC is detected, Freeze Frame Data is not recorded.), then erase the DTC
and the data. (Refer to EC-34 .) The (1st/2nd trip) DTC and the freeze frame data can be used when duplicating the
incident at STEP III & IV.
If the incident cannot be verified, perform EC-75, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
Study the relationship between the cause, specified by (1st/2nd trip) DTC, and the symptom described by the customer. (The Symptom Matrix Chart will be useful. See EC-48 .)
Also check related service bulletins for information.

STEP III

Try to confirm the symptom and under what conditions the incident occurs.
The DIAGNOSTIC WORK SHEET and the freeze frame data are useful to verify the incident. Connect CONSULT-II
to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform EC-75, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
If the malfunction code is detected, skip STEP IV and perform STEP V.

STEP IV

Try to detect the (1st/2nd trip) DTC by driving in (or performing) the DTC Confirmation Procedure. Check and read
the (1st/2nd trip) DTC and freeze frame data by using CONSULT-II or GST.
During the (1st/2nd trip) DTC verification, be sure to connect CONSULT-II to the vehicle in DATA MONITOR (AUTO
TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform EC-75, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
In case the DTC Confirmation Procedure is not available, perform the Overall Function Check instead. The (1st/2nd
trip) DTC cannot be displayed by this check, however, this simplified check is an effective alternative.
The NG result of the Overall Function Check is the same as the (1st/2nd trip) DTC detection.

STEP V

Take the appropriate action based on the results of STEP I through IV.
If the malfunction code is indicated, proceed to TROUBLE DIAGNOSIS FOR DTC PXXXX.
If the normal code is indicated, proceed to the BASIC INSPECTION. (Refer to EC-44 .)Then perform inspections
according to the Symptom Matrix Chart. (Refer to EC-48 .)

STEP VI

Identify where to begin diagnosis based on the relationship study between symptom and possible causes. Inspect the
system for mechanical binding, loose connectors or wiring damage using (tracing) Harness Layouts.
Gently shake the related connectors, components or wiring harness with CONSULT-II set in DATA MONITOR
(AUTO TRIG) mode.
Check the voltage of the related ECM terminals or monitor the output data from the related sensors with CONSULT-II.
Refer to EC-57 , EC-72 .
The Diagnostic Procedure in EC section contains a description based on open circuit inspection. A short circuit
inspection is also required for the circuit check in the Diagnostic Procedure. For details, refer to Circuit Inspection in
GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" .
Repair or replace the malfunction parts.
If malfunctioning part cannot be detected, perform EC-75, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .

STEP VII

Once you have repaired the circuit or replaced a component, you need to run the engine in the same conditions and
circumstances which resulted in the customer's initial complaint.
Perform the DTC Confirmation Procedure and confirm the normal code [DTC No. P0000] is detected. If the incident is
still detected in the final check, perform STEP VI by using a method different from the previous one.
Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) (1st/2nd trip) DTC in
ECM. (Refer to EC-34, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .)

DIAGNOSTIC WORK SHEET

There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about an incident. It is
important to fully understand the symptoms or conditions for a customer complaint.
Utilize a diagnostic worksheet like the one shown below in order to
organize all the information for troubleshooting.

CONSULT-II has two kinds of triggers and they can be selected by touching SETTING in DATA MONITOR
mode.
1. AUTO TRIG (Automatic trigger):

The malfunction will be identified on the CONSULT-II screen in

real time.
In other words, DTC/1st trip DTC/2nd trip DTC will be displayed
if the malfunction is detected by ECM.
At the moment a malfunction is detected by ECM, MONITOR
in DATA MONITOR screen is changed to Recording Data ...
xx% as shown in the figure, and the data after the malfunction
detection is recorded. Then when the percentage reached
100%, REAL-TIME DIAG screen is displayed. If STOP is
touched on the screen during Recording Data ... xx%, REALPBIB0480E
TIME DIAG screen is also displayed.
The recording time after the malfunction detection and the recording speed can be changed by TRIGGER POINT and Recording Speed. Refer to CONSULT-II OPERATION MANUAL.
2. MANU TRIG (Manual trigger):

DTC/1st trip DTC/2nd trip DTC will not be displayed automatically on CONSULT-II screen even though a malfunction is
detected by ECM.
DATA MONITOR can be performed continuously even though a
malfunction is detected.
Use these triggers as follows:
1. AUTO TRIG

While trying to detect the DTC/1st trip DTC/2nd trip DTC by performing the DTC Confirmation Procedure, be sure to select to
SEF707X
DATA MONITOR (AUTO TRIG) mode. You can confirm the
malfunction at the moment it is detected.

While narrowing down the possible causes, CONSULT-II should be set in DATA MONITOR (AUTO
TRIG) mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, components
and harness in the DTC Confirmation Procedure, the moment a malfunction is found the DTC/1st trip
DTC/2nd trip DTC will be displayed. Refer to GI-24, "How to Perform Efficient Diagnosis for an Electrical
Incident" , INCIDENT SIMULATION TESTS.
2. MANU TRIG

EC-69

TROUBLE DIAGNOSIS
[YD (WITH EURO-OBD)]

If the malfunction is displayed as soon as DATA MONITOR is selected, reset CONSULT-II to MANU
TRIG. By selecting MANU TRIG you can monitor and store the data. The data can be utilized for further
diagnosis, such as a comparison with the value for the normal operating condition.

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT

Description

PFP:00006

A
EBS013JV

Intermittent incidents (I/I) may occur. In many cases, the incident resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's EC
complaint often do not recur on (1st/2nd trip) DTC visits. Realize also that the most frequent cause of I/I occurrences is poor electrical connections. Because of this, the conditions under which the incident occurred may
not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may not indicate the
C
specific malfunctioning area.

Ground Inspection

EBS013K1

Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:

Remove the ground bolt or screw.

Inspect all mating surfaces for tarnish, dirt, rust, etc.

Clean as required to assure good contact.

Reinstall bolt or screw securely.

Inspect for add-on accessories which may be interfering with the ground circuit.

If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.
For detailed ground distribution information, refer to Ground Distribution in PG section.

DTC P0101 MAF SENSOR

Component Description

PFP:22680
EBS013KU

The mass air flow sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake
flow. The mass air flow sensor controls the temperature of the hot
wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.

The intake air temperature sensor is built into mass air flow sensor.
The sensor detects intake air temperature and transmits a signal to
the ECM.
The temperature sensing unit uses a thermistor which is sensitive to
the change in temperature. Electrical resistance of the thermistor
decreases in response to the temperature rise.

DTC P0201 - P0204 FUEL INJECTOR

Component Description

PFP:16600

A
EBS013MJ

The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

phases. It operates according to the output pulse signal of the ECM.
Two windings are turned ON and OFF in sequence. Each time an
ON pulse is issued, the valve opens or closes, changing the flow
rate. When no change in the flow rate is needed, the ECM does not
issue the pulse signal. A certain voltage signal is issued so that the
valve remains at that particular opening.

Component Description

PFP:16600

A
EBS013QZ

The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

DTC P2146, P2149 FUEL INJECTOR POWER SUPPLY

Component Description

PFP:16600
EBS013SH

The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

BASIC ASCD SYSTEM

Refer to Owner's Manual for ASCD operating instructions.
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed
without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/
h (25 MPH) and 185 km/h (115 MPH).
ECM controls fuel injection value to regulate engine speed.
Operation status of ASCD is indicated by CRUISE indicator and SET indicator in combination meter. If any
malfunction occurs in ASCD system, it automatically deactivates control.

SET OPERATION
Press ASCD ON/OFF switch (Main switch). (The CRUISE indicator in combination meter illuminates.)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 185 km/h (115
MPH), press SET switch. (Then SET indicator in combination meter illuminates.)

ACCEL OPERATION
If the RESUME/ACCEL switch is depressed during cruise control driving, increase the vehicle speed until the
switch is released or vehicle speed reaches maximum speed controlled by the system.
And then ASCD will keep the new set speed.

CANCEL OPERATION
When any of following conditions exist, cruise operation will be canceled.

CANCEL switch is depressed

More than 2 switches at ASCD steering switch are depressed at the same time (Set speed will be
cleared.).

Brake pedal is depressed

Clutch pedal is depressed or gear position is changed to the neutral position

Vehicle speed increased to 13 km/h higher than the set speed

Vehicle speed decreased to 13 km/h lower than the set speed

ESP/TCS system is operated

When the ECM detects any of the following conditions, the ECM will cancel the cruise operation and inform
the driver by blinking indicator lamp.

Malfunction for some self-diagnoses regarding ASCD control: SET lamp will blink quickly.
If MAIN switch is turned to OFF during ASCD is activated, all of ASCD operations will be canceled and vehicle
speed memory will be erased.

COAST OPERATION
When the SET/COAST switch is depressed during cruise control driving, decrease vehicle set speed until the
switch is released. And then ASCD will keep the new set speed.

RESUME OPERATION
When the RESUME/ACCEL switch is depressed after cancel operation other than depressing ON/OFF switch
is performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must
meet following conditions.

Brake pedal is released

Clutch pedal is released

Vehicle speed is greater than 40 km/h (25 MPH) and less than 185 km/h (115 MPH)

[YD (WITHOUT EURO-OBD)]

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) AIR BAG and SEAT
BELT PRE-TENSIONER

EBS0152M

The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used along EC
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
C
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be perD
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
E
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
F

On Board Diagnostic (OBD) System of Engine

EBS0152N

The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:

Be sure to turn the ignition switch OFF and disconnect the battery ground cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MI to light up.

Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

Certain systems and components, especially those related to OBD, may use a new style slidelocking type harness connector. For description and how to disconnect, refer to PG-108, "HARNESS CONNECTOR" .

Be sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.

Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel system, etc.

Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.

Precautions

EBS0152O

Always use a 12 volt battery as power source.

Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect battery
ground cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
Before removing parts, turn ignition switch OFF and then
disconnect battery ground cable.
SEF289H

EC-355

PRECAUTIONS
[YD (WITHOUT EURO-OBD)]

Do not disassemble ECM.

MBIB0625E

When connecting ECM harness connector, fasten it

securely with levers as far as they will go as shown in the
figure.

MBIB0145E

When connecting or disconnecting pin connectors into or

from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to IC's.
Keep engine control system harness at least 10cm (4 in)
away from adjacent harness, to prevent engine control system malfunctions due to receiving external noise, degraded
operation of IC's, etc.
Keep engine control system parts and harness dry.
Before replacing ECM, perform ECM Terminals and Reference Value inspection and make sure ECM functions properly. Refer to EC-391, "ECM Terminals And Reference
Value" .
Handle mass air flow sensor carefully to avoid damage.
Do not disassemble mass air flow sensor.
Do not clean mass air flow sensor with any type of detergent.
Even a slight leak in the air intake system can cause serious incidents.
Do not shock or jar the camshaft position sensor, crankshaft position sensor.

EC-356

PRECAUTIONS
[YD (WITHOUT EURO-OBD)]

After performing each TROUBLE DIAGNOSIS, perform DTC

Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.

Fuel Injection Control System

EBS0152V

SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.

When the ECM receives a start signal from the ignition switch, the
ECM adapts the fuel injection system for the start control. The
amount of fuel injected at engine starting is a preset program value
in the ECM. The program is determined by the engine speed, engine
coolant temperature and fuel rail pressure.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches the specific value, and shifts the control to the normal or idle
control.

*: The input signal is sent to the ECM through CAN communication line.

When the ECM determines that the engine speed is at idle, the fuel injection system is adapted for the idle
control. The ECM regulates the amount of fuel injected corresponding to changes in load applied to the engine
to keep engine speed constant. The ECM also provides the system with a fast idle control in response to the
engine coolant temperature signal.

The amount of fuel injected under normal driving conditions is determined according to sensor signals. The crankshaft position sensor
detects engine speed, the accelerator pedal position sensor detects
accelerator pedal position and fuel rail pressure sensor detects fuel
rail pressure. These sensors send signals to the ECM.
The fuel injection data, predetermined by correlation between various engine speeds, accelerator pedal positions and fuel rail pressure are stored in the ECM memory, forming a map. The ECM
determines the optimal amount of fuel to be injected using the sensor signals in comparison with the map.

If the engine speed is above 2,800 rpm under no load (for example, the shift position is neutral and engine
speed is over 2,800 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies
based on engine speed. Fuel cut will be operated until the engine speed reaches 1,500 rpm, then fuel cut will
be cancelled.

CAN Communication

EBS01530

SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

BASIC SERVICE PROCEDURE

Fuel Filter

PFP:00018
EBS01531

DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.

AIR BLEEDING
Pump the priming pump to bleed air.

When air is bled completely, the pumping of the priming pump

suddenly becomes heavy. Stop the operation at that time.

If it is difficult to bleed air by the pumping of the priming pump

(the pumping of the priming pump does not become heavy), disconnect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.

Start engine and let it idle for at least 1 minute after performing
air bleeding.

Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.
It is not necessary to disconnect the fuel hose.
Using a tool such as a pliers, loosen the water draining cock at
the bottom of the fuel filter.
Loosening drain cock four to five turns causes water to
start draining.
Do not remove drain cock by loosening it excessively.
If water dose not drain properly, move the priming up and down.
CAUTION:
When the water is drained, the fuel is also drained. Use a
pan, etc. to avoid fuel adherence to the rubber parts such as
the engine mount insulator.
Do not over-tighten the water draining cock. This will damSMA825B
age the cock thread, resulting in water or fuel leak.
Bleed air of the fuel filter. Refer to EC-368, "AIR BLEEDING" .
Start the engine.

Fuel Pump Learning Value Clearing

EBS01532

DESCRIPTION
In order to always keep optimum fuel pressure in fuel rail, the ECM controls fuel pump in high precision with
monitoring the signal of fuel rail pressure sensor.
Accordingly, the ECM always learns characteristic value of fuel pump. Fuel Pump Learning Value Clearing is
an operating to clear the value of the fuel pump learning.
It must be performed after the fuel pump is changed. When the ECM is replaced with brand new one, the Fuel
Pump Learning Value Clearing is not necessary to be performed. If the ECM to be replaced has the possibility
of learning the characteristic value of fuel pump, the Fuel Pump Learning Value Clearing is necessary to be
performed after the ECM has been replaced.

OPERATION PROCEDURE
NOTE:
Remove fuel pump without starting engine after performing Fuel Pump Learning Value Clearing.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

DTC and MI Detection Logic

PFP:00028
EBS01533

When a malfunction is detected, the malfunction (DTC) and freeze frame data are stored in the ECM memory.
The MI will light up each time the ECM detects malfunction. For diagnostic items causing the MI to light up,
refer to EC-351, "INDEX FOR DTC" .

Diagnostic Trouble Code (DTC)

EBS01534

HOW TO READ DTC

The DTC can be read by CONSULT-II only.

With CONSULT-II
CONSULT-II displays the DTC in "SELF-DIAG RESULTS" mode. Example: P0117, P0335, P1260, etc. These
DTCs are prescribed by ISO15031-5.
(CONSULT-II also displays the malfunctioning component or system.)

HOW TO ERASE DTC

How to Erase DTC ( With CONSULT-II)
1.
2.
3.
4.

If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
Touch ENGINE.
Touch SELF-DIAG RESULTS.
Touch ERASE. (The DTC in the ECM will be erased.)

MBIB0895E

The emission related diagnostic information in the ECM can be erased by selecting ERASE in the SELFDIAG RESULTS mode with CONSULT-II.

Freeze Frame Data

EBS01535

The ECM records the driving conditions such as calculated load value, engine coolant temperature, engine
speed, vehicle speed and intake manifold pressure at the moment a malfunction is detected.
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II. For
details, see EC-399 .
Only one set of freeze frame data can be stored in the ECM. If freeze frame data is stored in the ECM memory
and another freeze frame data occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clearing the ECM memory are described in EC-370, "HOW TO ERASE DTC" .

Malfunction Indicator (MI)

EBS01537

DESCRIPTION

The MI is located on the instrument panel.

1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
If the MI does not light up, refer to DI-84, "WARNING LAMPS"
or see EC-652 .
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.

TROUBLE DIAGNOSIS
[YD (WITHOUT EURO-OBD)]

TROUBLE DIAGNOSIS
Trouble Diagnosis Introduction

PFP:00004
EBS015RN

INTRODUCTION
The engine has an ECM to control major systems such as fuel injection control, fuel injection timing control, glow control system, etc.
The ECM accepts input signals from sensors and instantly actuators.
It is essential that both input and output signals are proper and stable. At the same time, it is important that there are no malfunctions
such as vacuum leaks, or other malfunctions with the engine.

MEF036D

It is much more difficult to diagnose a malfunction that occurs intermittently rather than continuously. Most intermittent malfunctions are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replacement of good parts.

SEF233G

A visual check only may not find the cause of the incidents. A road
test with CONSULT-II or a circuit tester connected should be performed. Follow the EC-375, "WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer can supply good information about such incidents, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A Diagnostic Worksheet like the example
on next page should be used.
Start your diagnosis by looking for conventional incidents first. This
will help troubleshoot driveability incidents on an electronically controlled engine vehicle.

[YD (WITHOUT EURO-OBD)]
Description for Work Flow
STEP

DESCRIPTION

STEP I

Get detailed information about the conditions and the environment when the incident/symptom occurred using the
EC-376, "DIAGNOSTIC WORK SHEET" .

STEP II

Before confirming the concern, check and write down (print out using CONSULT-II) the DTC and the freeze frame
data, then erase the DTC. The DTC and the freeze frame data can be used when duplicating the incident at STEP III
& IV. Refer to EC-370 .
If the incident cannot be verified, perform EC-408, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
Study the relationship between the cause, specified by DTC, and the symptom described by the customer. (The
Symptom Matrix Chart will be useful. Refer to EC-382 .) Also check related service bulletins for information.

STEP III

Try to confirm the symptom and under what conditions the incident occurs.
The DIAGNOSTIC WORK SHEET and the freeze frame data are useful to verify the incident. Connect CONSULT-II
to the vehicle in DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform EC-408, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
If the malfunction code is detected, skip STEP IV and perform STEP V.

STEP IV

Try to detect the DTC by driving in (or performing) the DTC Confirmation Procedure. Check and read the DTC and the
freeze frame data by using CONSULT-II.
During the DTC verification, be sure to connect CONSULT-II to the vehicle in DATA MONITOR (AUTO TRIG) mode
and check real time diagnosis results.
If the incident cannot be verified, perform EC-408, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
In case the DTC Confirmation Procedure is not available, perform the Overall Function Check instead. The DTC cannot be displayed by this check, however, this simplified check is an effective alternative.
The NG result of the Overall Function Check is the same as the DTC detection.

STEP V

Take the appropriate action based on the results of STEP I through IV.
If the malfunction code is indicated, proceed to Trouble Diagnosis for DTC PXXXX.
If the normal code is indicated, proceed to the Basic Inspection, EC-378 . Then perform inspections according to the
Symptom Matrix Chart. Refer to EC-382 .

STEP VI

Identify where to begin diagnosis based on the relationship study between symptom and possible causes. Inspect the
system for mechanical binding, loose connectors or wiring damage using (tracing) Harness Layouts.
Gently shake the related connectors, components or wiring harness with CONSULT-II set in DATA MONITOR (AUTO
TRIG) mode.
Check the voltage of the related ECM terminals or monitor the output data from the related sensors with CONSULT-II.
Refer to EC-391 or EC-404 .
The Diagnostic Procedure in EC section contains a description based on open circuit inspection. A short circuit
inspection is also required for the circuit check in the Diagnostic Procedure. For details, refer to GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" , Circuit Inspection.
Repair or replace the malfunction parts.
If the malfunctioning part cannot be detected, perform EC-408, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .

STEP VII

Once you have repaired the circuit or replaced a component, you need to run the engine in the same conditions and
circumstances which resulted in the customer's initial complaint.
Perform the DTC Confirmation Procedure and confirm the normal code (DTC P0000) is detected. If the incident is still
detected in the final check, perform STEP VI by using a different method from the previous one.
Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) DTC in ECM. (Refer to
EC-370 .)

DIAGNOSTIC WORK SHEET

There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about an incident. It is
important to fully understand the symptoms or conditions for a customer complaint.
Utilize a diagnostic worksheet like the one shown below in order to
organize all the information for troubleshooting.

REAL TIME DIAGNOSIS IN DATA MONITOR MODE

CONSULT-II has two kinds of triggers and they can be selected by touching SETTING in DATA MONITOR
mode.
1. AUTO TRIG (Automatic trigger):

The malfunction will be identified on the CONSULT-II screen in

real time.
In other words, DTC will be displayed if the malfunction is
detected by ECM.
At the moment a malfunction is detected by ECM, MONITOR
in DATA MONITOR screen is changed to Recording Data ...
xx% as shown in the figure, and the data after the malfunction
detection is recorded. Then when the percentage reached
100%, REAL-TIME DIAG screen is displayed. If STOP is
touched on the screen during Recording Data ... xx%, REALPBIB0480E
TIME DIAG screen is also displayed.
The recording time after the malfunction detection and the recording speed can be changed by TRIGGER POINT and Recording Speed. Refer to CONSULT-II OPERATION MANUAL.
2. MANU TRIG (Manual trigger):

DTC will not be displayed automatically on CONSULT-II screen

even though a malfunction is detected by ECM.
DATA MONITOR can be performed continuously even though a
malfunction is detected.
Use these triggers as follows:
1. AUTO TRIG

While trying to detect the DTC by performing the DTC Confirmation Procedure, be sure to select to DATA MONITOR (AUTO
TRIG) mode. You can confirm the malfunction at the moment it
SEF707X
is detected.

While narrowing down the possible causes, CONSULT-II should be set in DATA MONITOR (AUTO
TRIG) mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, components
and harness in the DTC Confirmation Procedure, the moment a malfunction is found the DTC will be displayed. Refer to GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" , INCIDENT SIMULATION TESTS.
2. MANU TRIG

EC-403

TROUBLE DIAGNOSIS
[YD (WITHOUT EURO-OBD)]

If the malfunction is displayed as soon as DATA MONITOR is selected, reset CONSULT-II to MANU
TRIG. By selecting MANU TRIG you can monitor and store the data. The data can be utilized for further
diagnosis, such as a comparison with the value for the normal operating condition.

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT

Description

PFP:00006
EBS0153K

Intermittent incidents (I/I) may occur. In many cases, the incident resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's
complaint often do not recur on DTC visits. Realize also that the most frequent cause of I/I occurrences is poor
electrical connections. Because of this, the conditions under which the incident occurred may not be clear.
Therefore, circuit checks made as part of the standard diagnostic procedure may not indicate the specific malfunctioning area.

COMMON I/I REPORT SITUATIONS

Ground Inspection

EBS0153Q

A
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasti- EC
cally affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
C

Remove the ground bolt or screw.

Inspect all mating surfaces for tarnish, dirt, rust, etc.

D

Clean as required to assure good contact.

Reinstall bolt or screw securely.

Inspect for add-on accessories which may be interfering with the ground circuit.

If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the E
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.
F
For detailed ground distribution information, refer to Ground Distribution in PG section.

Description

PFP:23710
EBS0153R

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Component Description

PFP:22680
EBS0154C

The mass air flow sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake
flow. The mass air flow sensor controls the temperature of the hot
wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.

DTC P0201 - P0204 FUEL INJECTOR

Component Description

PFP:16600
EBS0155S

The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

DTC P0628, P0629 FUEL PUMP

Description

PFP:16700

A
EBS0158Z

To control the amount of the fuel inhalation of the fuel pump, a plunger is built into the fuel pump. When the
amount of the fuel inhalation of fuel increases, the fuel pump raises the fuel exhalation pressure. As a result, EC
the fuel injection pressure is raised. When the load of the engine increases, the ECM sends a signal to the fuel
pump to raise the injection pressure.

DTC P1268 - P1271 FUEL INJECTOR

Component Description

PFP:16600
EBS015AC

The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

DTC P1275 FUEL PUMP

Description

PFP:16700

A
EBS015BC

To control the amount of the fuel inhalation of the fuel pump, a plunger is built into the fuel pump. When the
amount of the fuel inhalation of fuel increases, the fuel pump raises the fuel exhalation pressure. As a result, EC
the fuel injection pressure is raised. When the load of the engine increases, the ECM sends a signal to fuel
pump to raise the injection pressure.

Component Description

PFP:16600
EBS015BU

The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake cylinder.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

*: This signal is sent to the ECM through CAN communication line.

This system controls flow rate of EGR led from exhaust manifold to intake manifold. The opening of the EGR
by-pass passage in the EGR volume control valve changes to control the flow rate. A built-in step motor
moves the valve in steps corresponding to the ECM output pulses. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is determined by considering various engine conditions.
The EGR volume control valve remains close under the following conditions.

Engine stopped

Engine starting

Low engine coolant temperature

Excessively high engine coolant temperature

High engine speed

Wide open throttle

SEF908Y

COMPONENT DESCRIPTION
EGR Volume Control Valve
The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the ECM.
Two windings are turned ON and OFF in sequence. Each time an
ON pulse is issued, the valve opens or closes, changing the flow
rate. When no change in the flow rate is needed, the ECM does not
issue the pulse signal. A certain voltage signal is issued so that the
valve remains at that particular opening.

BASIC ASCD SYSTEM

Refer to Owner's Manual for ASCD operating instructions.
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed
without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/
h (25 MPH) and 185 km/h (115 MPH).
ECM controls fuel injection value to regulate engine speed.
Operation status of ASCD is indicated by CRUISE indicator and SET indicator in combination meter. If any
malfunction occurs in ASCD system, it automatically deactivates control.

SET OPERATION

Press ASCD ON/OFF switch (Main switch). (The CRUISE indicator in combination meter illuminates.)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 185 km/h (115
MPH), press SET switch. (Then SET indicator in combination meter illuminates.)

ACCEL OPERATION
If the RESUME/ACCEL switch is depressed during cruise control driving, increase the vehicle speed until the
switch is released or vehicle speed reaches maximum speed controlled by the system.
And then ASCD will keep the new set speed.

CANCEL OPERATION
When any of following conditions exist, cruise operation will be canceled.

CANCEL switch is depressed

More than 2 switches at ASCD steering switch are depressed at the same time (Set speed will be
cleared.).

Brake pedal is depressed

Clutch pedal is depressed or gear position is changed to the neutral position

Vehicle speed increased to 13 km/h higher than the set speed

Vehicle speed decreased to 13 km/h lower than the set speed

ESP/TCS system is operated

When the ECM detects any of the following conditions, the ECM will cancel the cruise operation and inform
the driver by blinking indicator lamp.

Malfunction for some self-diagnoses regarding ASCD control: SET lamp will blink quickly.
If MAIN switch is turned to OFF during ASCD is activated, all of ASCD operations will be canceled and vehicle
speed memory will be erased.

COAST OPERATION
When the SET/COAST switch is depressed during cruise control driving, decrease vehicle set speed until the
switch is released. And then ASCD will keep the new set speed.

RESUME OPERATION
When the RESUME/ACCEL switch is depressed after cancel operation other than depressing ON/OFF switch
is performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must
meet following conditions.

Brake pedal is released

Clutch pedal is released

Vehicle speed is greater than 40 km/h (25 MPH) and less than 185 km/h (115 MPH)
