PRECAUTIONS

PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” ECS005KO

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
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. AT
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 per-
formed by an authorized NISSAN/INFINITI dealer. D
● Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section. E
● 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
Precautions for On Board Diagnostic (EURO-OBD) System of A/T and Engine —
For Hong Kong — ECS00DPS
G
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION: H
● Be sure to turn the ignition switch “OFF” and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MIL to light up.
I
● Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
● Be sure to route and secure the harnesses properly after work. Interference of the harness with a J
bracket, etc. may cause the MIL to light up due to a short circuit.
● Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc. K
● Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
L
Precautions for Trouble Diagnosis ECS005KQ

CAN SYSTEM
● Do not apply voltage of 7.0V or higher to the measurement terminals. M
● Use the tester with its open terminal voltage being 7.0V or less.
Precautions for Harness Repair ECS005KR

CAN SYSTEM
● Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in)]

PKIA0306E

AT-7
PRECAUTIONS

● Do not perform bypass wire connections for the repair


parts.(The spliced wire will become separated and the charac-
teristics of twisted line will be lost.)

PKIA0307E

Precautions ECS005KS

● Before connecting or disconnecting the TCM harness con-


nector, turn ignition switch OFF and disconnect negative
battery terminal. Failure to do so may damage the TCM.
Because battery voltage is applied to TCM even if ignition
switch is turned off.

SEF289H

● When connecting or disconnecting pin connectors into or


from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.

AAT470A

● Before replacing TCM, perform TCM input/output signal


inspection and make sure whether TCM functions properly
or not. (See page AT-248, "TCM Terminals and Reference
Value".)

MEF040DA

AT-8
PRECAUTIONS

● After performing each TROUBLE DIAGNOSIS, perform


“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE- A
DURE”.
The DTC should not be displayed in the “DTC CONFIRMA-
TION PROCEDURE” if the repair is completed.
B
● Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
AT
● Disassembly should be done in a clean work area.
● Use lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the operation SAT652J

of the transaxle. D
● Place disassembled parts in order for easier and proper assembly.
● All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
E
reassembly.
● Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
● It is very important to perform functional tests whenever they are indicated.
F
● The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
G
● Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
● Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
H
● Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
● After overhaul, refill the transaxle with new ATF.
● When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque I
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to “Changing A/T Fluid”, AT-16, "A/T FLUID" .
J
Service Notice or Precautions ECS005KT

FAIL-SAFE
The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major K
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs in third gear, even with a shift lever position of “1”, “2” or “D”. The cus-
tomer may complain of sluggish or poor acceleration.
When the ignition key is turned “ON” following Fail-Safe operation, O/D OFF or A/T CHECK indicator lamp L
blinks for about 8 seconds. Refer to AT-205, "Diagnostic Procedure Without CONSULT-II" .
The blinking of the O/D OFF or A/T CHECK indicator lamp for about 8 seconds will appear only once and be
cleared. The customer may resume normal driving conditions. M
Always follow the “WORK FLOW”, refer to AT-216, "Work Flow" .
The SELF-DIAGNOSIS results will be as follows:
● The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
● During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
● External leaks in the hub weld area.
● Converter hub is scored or damaged.
● Converter pilot is broken, damaged or fits poorly into crankshaft.
● Steel particles are found after flushing the cooler and cooler lines.

PRECAUTIONS

● Internal failure of stator roller clutch.


● Heavy clutch debris due to overheating (blue converter).
● Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
● The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
● The threads in one or more of the converter bolt holes are damaged.
● Transaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
● Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
EURO-OBD SELF-DIAGNOSIS — EURO-OBD —
● A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the O/D OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the
table on AT-45, "SELF-DIAGNOSTIC RESULT TEST MODE" for the indicator used to display each self-
diagnostic result.
● The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure “HOW TO ERASE DTC” on AT-42, "HOW TO ERASE DTC" to com-
plete the repair and avoid unnecessary blinking of the MIL.
● The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the O/D OFF indicator lamp does not indicate any malfunctions.
– PNP switch
– A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of EURO-OBD, refer to EC-42, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
● Certain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer to PG-72, "HARNESS CONNECTOR" .

CAN Communication ECS008MY

SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic 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.

Control Mechanism ECS005L5

LINE PRESSURE CONTROL A


TCM has various line pressure control characteristics to match the driving conditions.
An ON-OFF duty signal is sent to the line pressure solenoid valve based on TCM characteristics.
Hydraulic pressure on the clutch and brake is electronically controlled through the line pressure solenoid valve B
to accommodate engine torque. This results in smooth shift operation.
Normal control
The line pressure to throttle opening characteristics is set for suitable AT
clutch operation.

SAT003J
F

Back-Up control (Engine brake)


If the selector lever is shifted to “2” position while driving in D4 (OD) G
or D3 , great driving force is applied to the clutch inside the transmis-
sion. Clutch operating pressure (line pressure) must be increased to
deal with this driving force.
H

SAT004J J
During shift change
The line pressure is temporarily reduced corresponding to a change
in engine torque when shifting gears (that is, when the shift solenoid K
valve is switched for clutch operation) to reduce shifting shock.

SAT005J

At low fluid temperature


● Fluid viscosity and frictional characteristics of the clutch facing change with fluid temperature. Clutch
engaging or band-contacting pressure is compensated for, according to fluid temperature, to stabilize
shifting quality.

AT-33
OVERALL SYSTEM

● The line pressure is reduced below 60°C (140°F) to prevent


shifting shock due to low viscosity of automatic transmission
fluid when temperature is low.

SAT006J

● Line pressure is increased to a maximum irrespective of the


throttle opening when fluid temperature drops to −10°C (14°F).
This pressure rise is adopted to prevent a delay in clutch and
brake operation due to extreme drop of fluid viscosity at low
temperature.

SAT007J

SHIFT CONTROL
The shift is regulated entirely by electronic control to accommodate vehicle speed and varying engine opera-
tions. This is accomplished by electrical signals transmitted by the revolution sensor and throttle position sen-
sor. This results in improved acceleration performance and fuel economy.
Control of shift solenoid valves A and B
The TCM activates shift solenoid valves A and B according to sig-
nals from the throttle position sensor and revolution sensor to select
the optimum gear position on the basis of the shift schedule memo-
rized in the TCM.
The shift solenoid valve performs simple ON-OFF operation. When
set to “ON”, the drain circuit closes and pilot pressure is applied to
the shift valve.

AT-34
OVERALL SYSTEM

Pilot pressure generated by the operation of shift solenoid valves A and B is applied to the end face of shift
valves A and B. A
The drawing above shows the operation of shift valve B. When the shift solenoid valve is “ON”, pilot pressure
applied to the end face of the shift valve overcomes spring force, moving the valve upward.
LOCK-UP CONTROL B
The torque converter clutch piston in the torque converter is locked to eliminate torque converter slip to
increase power transmission efficiency. The solenoid valve is controlled by an ON-OFF duty signal sent from
the TCM. The signal is converted to an oil pressure signal which controls the torque converter clutch piston. AT
Conditions for lock-Up operation
When vehicle is driven in 3rd and 4th gear position, vehicle speed and throttle opening are detected. If the
detected values fall within the lock-up zone memorized in the TCM, lock-up is performed. D

Torque converter clutch solenoid valve control
The torque converter clutch solenoid valve is controlled by the TCM.
The plunger closes the drain circuit during the “OFF” period, and H
opens the circuit during the “ON” period. If the percentage of OFF-
time increases in one cycle, the pilot pressure drain time is reduced
and pilot pressure remains high. I

OVERALL SYSTEM

Torque converter clutch control valve operation

AAT155A

Lock-up released
The OFF-duration of the torque converter clutch solenoid valve is long, and pilot pressure is high. The pilot
pressure pushes the end face of the torque converter clutch control valve in combination with spring force to
move the valve to the left. As a result, converter pressure is applied to chamber A (torque converter clutch pis-
ton release side). Accordingly, the torque converter clutch piston remains unlocked.
Lock-up applied
When the OFF-duration of the torque converter clutch solenoid valve is short, pilot pressure drains and
becomes low. Accordingly, the control valve moves to the right by the pilot pressure of the other circuit and
converter pressure. As a result, converter pressure is applied to chamber B, keeping the torque converter
clutch piston applied.
Also smooth lock-up is provided by transient application and release of the lock-up.

OVERRUN CLUTCH CONTROL (ENGINE BRAKE CONTROL)


Forward one-way clutch is used to reduce shifting shocks in downshifting operations. This clutch transmits A
engine torque to the wheels. However, drive force from the wheels is not transmitted to the engine because
the one-way clutch rotates idle. This means the engine brake is not effective.
The overrun clutch operates when the engine brake is needed. B

Overrun clutch control valve operation


When the solenoid valve is “ON”, pilot pressure is applied to the
overrun clutch control valve. This pushes up the overrun clutch con-
trol valve. The line pressure is then shut off so that the clutch does
not engage.
When the solenoid valve is “OFF”, pilot pressure is not generated. At
this point, the overrun clutch control valve moves downward by
spring force. As a result, overrun clutch operation pressure is pro-
vided by the overrun clutch reducing valve. This causes the overrun
clutch to engage.
In the 1 position, the overrun clutch control valve remains pushed
down so that the overrun clutch is engaged at all times.

Control Valve ECS005L6

FUNCTION OF CONTROL VALVES


Valve name Function
Pressure regulator valve, plug Regulates oil discharged from the oil pump to provide optimum line pressure for all driving condi-
and sleeve tions.
Pressure modifier valve and Used as a signal supplementary valve to the pressure regulator valve. Regulates pressure-modi-
sleeve fier pressure (signal pressure) which controls optimum line pressure for all driving conditions.
Pilot valve Regulates line pressure to maintain a constant pilot pressure level which controls lock-up mecha-
nism, overrun clutch, shift timing.
Accumulator control valve Regulates accumulator back-pressure to pressure suited to driving conditions.
Manual valve Directs line pressure to oil circuits corresponding to select positions.
Hydraulic pressure drains when the shift lever is in Neutral.
Shift valve A Simultaneously switches four oil circuits using output pressure of shift solenoid valve A to meet
driving conditions (vehicle speed, throttle opening, etc.).
Provides automatic downshifting and up-shifting (1st → 2nd → 3rd → 4th gears/4th → 3rd → 2nd
→ 1st gears) in combination with shift valve B.
Shift valve B Simultaneously switches three oil circuits using output pressure of shift solenoid valve B in rela-
tion to driving conditions (vehicle speed, throttle opening, etc.).
Provides automatic downshifting and up-shifting (1st → 2nd → 3rd → 4th gears/4th → 3rd → 2nd
→ 1st gears) in combination with shift valve A.
Overrun clutch control valve Switches hydraulic circuits to prevent engagement of the overrun clutch simultaneously with appli-
cation of the brake band in D4 . (Interlocking occurs if the overrun clutch engages during D4 .)
1st reducing valve Reduces low & reverse brake pressure to dampen engine-brake shock when down-shifting from
the “1” position 12 to 11 .
Overrun clutch reducing valve Reduces oil pressure directed to the overrun clutch and prevents engine-brake shock.
In “1” and “2” positions, line pressure acts on the overrun clutch reducing valve to increase the
pressure-regulating point, with resultant engine brake capability.
Torque converter relief valve Prevents an excessive rise in torque converter pressure.
Torque converter clutch control Activates or inactivates the lock-up function.
valve, plug and sleeve Also provides smooth lock-up through transient application and release of the lock-up system.
1-2 accumulator valve and piston Dampens the shock encountered when 2nd gear band servo contracts, and provides smooth
shifting.

Introduction ECS00DL8

The A/T system has two self-diagnostic systems.


The first is the emission-related on board diagnostic system (EURO-OBD) performed by the TCM in combina-
tion with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC
in the ECM memory but not the TCM memory.
The second is the TCM original self-diagnosis indicated by the O/D OFF indicator lamp. The malfunction is
stored in the TCM memory. The detected items are overlapped with EURO-OBD self-diagnostic items. For
detail, refer to AT-45, "SELF-DIAGNOSTIC RESULT TEST MODE" .
EURO-OBD Function for A/T System ECS00DL9

The ECM provides emission-related on board diagnostic (EURO-OBD) functions for the A/T system. One
function is to receive a signal from the TCM used with EURO-OBD-related parts of the A/T system. The signal
is sent to the ECM when a malfunction occurs in the corresponding EURO-OBD-related part. The other func-
tion is to indicate a diagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel.
Sensors, switches and solenoid valves are used as sensing elements.
The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relation
to A/T system parts.
One or Two Trip Detection Logic of EURO-OBD ECS00DLA

ONE TRIP DETECTION LOGIC


If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored in
the ECM memory as a DTC. The TCM is not provided with such a memory function.
TWO TRIP DETECTION LOGIC
When a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC
(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — First Trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MIL will illuminate. — Second Trip
A/T-related parts for which the MIL illuminates during the first or second test drive are listed below.
MIL
Items
One trip detection Two trip detection
Shift solenoid valve A — DTC: P0750 X
Shift solenoid valve B — DTC: P0755 X
Throttle position sensor — DTC: P1705 X
Except above X

The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
EURO-OBD Diagnostic Trouble Code (DTC) ECS00DLB

HOW TO READ DTC AND 1ST TRIP DTC


DTC and 1st trip DTC can be read by the following methods.
( With CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710,
P0720, P0725, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
● 1st trip DTC No. is the same as DTC No.
● Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. How-
ever, in case of the Mode II and GST they do not indicate whether the malfunction is still occurring
or occurred in the past and returned to normal.
CONSULT-II can identify them as shown below. Therefore, using CONSULT-II (if available) is rec-
ommended.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
[FOR HONG KONG]
A sample of CONSULT-II display for DTC is shown in the following
page. DTC or 1st trip DTC of a malfunction is displayed in SELF A

cates how many times the vehicle was driven after the last detection
of a DTC.

SAT016K

Freeze Frame Data and 1st Trip Freeze Frame Data


The ECM has a memory function, which stores the driving condition such as fuel system status, calculated L
load value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehicle
speed at the moment the ECM detects a malfunction.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II M
or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
detail, refer to EC-93, "CONSULT-II Function" .
Only one set of freeze frame data (either 1st trip freeze frame data of freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM.
The ECM has the following priorities to update the data.
Priority Items
Misfire — DTC: P0300 - P0306
1
Freeze frame data Fuel Injection System Function — DTC: P0171, P0172, P0174, P0175
2 Except the above items (Includes A/T related items)

Both 1st trip freeze frame data and freeze frame data (along with the DTCs) are cleared when the ECM mem-
ory is erased.

HOW TO ERASE DTC
The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as
described following.
● If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
● When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode
selector on the ECM.
The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC
related to EURO-OBD. For details, refer to EC-79, "Engine Control Component Parts Location" .
● Diagnostic trouble codes (DTC)
● 1st trip diagnostic trouble codes (1st trip DTC)
● Freeze frame data
● 1st trip freeze frame data
● System readiness test (SRT) codes
● Test values
HOW TO ERASE DTC (WITH CONSULT-II)
● If a DTC is displayed for both ECM and TCM, it needs to be erased for both ECM and TCM.

1. The malfunction indicator lamp will light up when the ignition


switch is turned ON without the engine running. This is for
checking the lamp.
● If the malfunction indicator does not light up, refer to DI-43,
"Schematic / Except for South Africa" .
(Or see MIL & CONSULT-II in EC section. Refer to EC-55,
"Malfunction Indicator Lamp (MIL)" or EC-93, "CONSULT-II

EC-42, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
CONSULT-II ECS00DLD

After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” AT-44 , place check marks for
results on the “DIAGNOSTIC WORKSHEET”, AT-60 . Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
– Actual shift schedule has more or less tolerance or allowance,
– Shift schedule indicated in Service Manual refers to the point where shifts start, and
– Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “ENGINE” for EURO-OBD
detected items or touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer to AT-97, "TCM Terminals and Reference Value" . If
result is NG, refer to PG-2, "POWER SUPPLY ROUTING" .

TROUBLE DIAGNOSIS — INTRODUCTION PFP:00000
A
Introduction ECS00DLF

The TCM receives a signal from the vehicle speed sensor, throttle
position sensor or PNP switch and provides shift control or lock-up B
control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the EURO-OBD related parts
of the A/T system for malfunction-diagnostic purposes. The TCM is AT
capable of diagnosing malfunctioning parts while the ECM can store
malfunctions in its memory.
Input and output signals must always be correct and stable in the D
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
SAT631IA
tion, etc.
E
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace- F
ment of good parts.
A visual check only, may not find the cause of the problems. A road
test with CONSULT-II (or GST) or a circuit tester connected should
G
be performed. Follow the “Work Flow”. Refer to AT-63, "Work Flow" .

H
SAT632I

Before undertaking actual checks, take a few minutes to talk with a


I
customer who approaches with a drive ability complaint. The cus-
tomer can supply good information about such problems, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Worksheet” like the exam- J
ple (AT-60, "DIAGNOSTIC WORKSHEET" ) should be used.
Start your diagnosis by looking for “conventional” problems first. This
will help troubleshoot drive ability problems on an electronically con- K
trolled engine vehicle.
Also check related Service bulletins for information.

DTC U1000 CAN COMMUNICATION LINE
[FOR HONG KONG]
DTC U1000 CAN COMMUNICATION LINE PFP:31940

Description ECS00DLN

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic 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.

Description ECS00DMU

● This malfunction will not be detected while the O/D OFF indicator lamp is indicating another self-diagnosis
malfunction.
● This malfunction is detected when the A/T does not shift into third gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such
as control valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band,
etc.

Shift solenoid valve A ON (Closed) OFF (Open) OFF (Open) ON (Closed)
Shift solenoid valve B ON (Closed) ON (Closed) OFF (Open) OFF (Open)

On Board Diagnostic Logic ECS00DMV

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (3rd) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve A is stuck closed.

CONSULT-II ECS005L7

After performing AT-205, "SELF-DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-II)" , place check marks
for results on the AT-213, "DIAGNOSTIC WORKSHEET" . Reference pages are provided following the items. B
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid). AT
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man- D
ual may differ slightly. This occurs because of the following reasons:
– Actual shift schedule has more or less tolerance or allowance,
E
– Shift schedule indicated in Service Manual refers to the point where shifts start, and
– Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
F
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
G
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir- H
cuit. Refer to AT-248, "TCM Terminals and Reference Value" . If

TROUBLE DIAGNOSIS — INTRODUCTION
[EXCEPT HONG KONG]
TROUBLE DIAGNOSIS — INTRODUCTION PFP:00000

Introduction ECS005L9

The TCM receives a signal from the vehicle speed sensor, accelera-
tor pedal position sensor or PNP switch and provides shift control or
lock-up control via A/T solenoid valves.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
SAT631IA
ment of good parts.
A visual check only, may not find the cause of the problems. A road
test with CONSULT-II or a circuit tester connected should be per-
formed. Follow the AT-216, "Work Flow" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a drive ability complaint. The cus-
tomer can supply good information about such problems, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Worksheet” like the exam-
ple (AT-213, "DIAGNOSTIC WORKSHEET" ) should be used.
Start your diagnosis by looking for “conventional” problems first. This
will help troubleshoot drive ability problems on an electronically con-
SAT632I
trolled engine vehicle.
Also check related Service bulletins for information.

HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR


A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a problem. It is important to fully understand the symptoms or
conditions for a customer complaint.
Make good use of the two sheets provided, “INFORMATION FROM CUSTOMER” (AT-213 ) and “DIAGNOS-
TIC WORKSHEET” (AT-214 ), to perform the best troubleshooting possible.

page.
In order to pinpoint the possible damaged components, follow the WORK FLOW shown in AT-216 .
NOTE: B
Stall revolution is too high in “D”, “2” or “1” position:
● Slippage occurs in 1st gear but not in 2nd and 3rd gears...... Low one-way clutch slippage
● Slippage occurs in the following gears: AT
1st through 3rd gears in “D” position and engine brake functions with overdrive control switch set to
“OFF”.
1st and 2nd gears in “2” position and engine brake functions with accelerator pedal released (fully closed D
throttle)...... Forward clutch or forward one-way clutch slippage
Stall revolution is too high in R position:
● Engine brake does not function in “1” position...... Low & reverse brake slippage E
● Engine brake functions in “1” position...... Reverse clutch slippage
Stall revolution within specifications:
● Vehicle does not achieve speed of more than 80 km/h (50 MPH)...... One-way clutch seizure in torque F
converter housing
CAUTION:
Be careful since automatic fluid temperature increases abnormally. G
● Slippage occurs in 3rd and 4th gears in “D” position...... High clutch slippage
● Slippage occurs in 2nd and 4th gear in “D” position...... Brake band slippage
● Engine brake does not function in 2nd and 3rd gears in “D” position, 2nd gear in “2” position, and 1st gear H

Description ECS005N6

CAN (Control Area Network) is a serial communication line for real time application. It is an on-vehicle multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic 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.
