 PRECAUTIONS
[RE4F04B]
PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” UCS000M9

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front AT
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING: D
● 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. E
● 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. F
● 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.
G
Precautions for On Board Diagnostic (OBD) System of A/T and Engine UCS000MA

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. H
CAUTION:
● 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, I
etc. will cause the MIL to light up.
● 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, J
dirt, bent terminals, etc.)
● Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit. K
● 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.
● Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM or L
ECM before returning the vehicle to the customer.
Precautions UCS000MB

M
● 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

AT-9
 PRECAUTIONS
[RE4F04B]
● 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. Refer to AT-99, "TCM INSPECTION TABLE" .

MEF040DA

● After performing each TROUBLE DIAGNOSIS, perform

“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
The DTC should not be displayed in the “DTC CONFIRMA-
TION PROCEDURE” if the repair is completed.
● 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.
● 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 SAT964I

of the transaxle.
● 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
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.
● 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.
● 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.
● Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
● Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
AT-11, "ATF COOLER SERVICE" .
● 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
converter and ATF cooling system.
Always follow the procedures when changing A/T fluid. Refer to MA-22, "Changing A/T Fluid" .

AT-10
 PRECAUTIONS
[RE4F04B]
Service Notice or Precautions UCS000MC

FAIL-SAFE A
The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
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- B
tomer may complain of sluggish or poor acceleration.
When the ignition key is turned ON following Fail-Safe operation, A/T CHECK indicator lamp blinks for about 8
seconds. [For “TCM Self-diagnostic Procedure (No Tools)”, refer to AT-54, "TCM SELF-DIAGNOSTIC PRO-
AT
CEDURE (NO TOOLS)" .]
The blinking of the A/T CHECK indicator lamp for about 8 seconds will appear only once and be cleared. The
customer may resume normal driving conditions.
Always follow the “Work Flow” (Refer to AT-63, "Work Flow" ). D
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. E
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
F
● External leaks in the hub weld area.
● Converter hub is scored or damaged.
● Converter pilot is broken, damaged or fits poorly into crankshaft. G
● Steel particles are found after flushing the cooler and cooler lines.
● Pump is damaged or steel particles are found in the converter.
● Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses H
have been made. (Converter clutch material may be glazed.)
● Converter is contaminated with engine coolant containing antifreeze.
● Internal failure of stator roller clutch. I
● 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. J
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. K
● 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.
L
● 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.
M
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T oil cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. Check Service Bullitens for latest A/T oil cooler cleaning pro-
cedure. For radiator replacement, refer to CO-10, "RADIATOR"
OBD-II SELF-DIAGNOSIS
● 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 A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table
on AT-44 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-41 to complete 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 A/T CHECK indicator lamp does not indicate any malfunctions.
– park/neutral position (PNP) switch

CAN Communication UCS0015M

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.
For details, refer to LAN-8, "CAN COMMUNICATION" .

Control Mechanism UCS000MM

LINE PRESSURE CONTROL

TCM has various line pressure control characteristics to meet 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
to accommodate engine torque. This results in smooth shift operation.
Normal Control
The line pressure to throttle opening characteristics is set for suitable
clutch operation.

SAT003J

Back-up Control (Engine brake)

If the selector lever is shifted to 2nd position while driving in D4 (O/
D) or D3 , great driving force is applied to the clutch inside the trans-
mission. Clutch operating pressure (line pressure) must be
increased to deal with this driving force.

SAT004J

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
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-32
 OVERALL SYSTEM
[RE4F04B]
● The line pressure is reduced below 60°C (140°F) to prevent
shifting shock due to low viscosity of automatic transmission A
fluid when temperature is low.

AT

SAT006J

D
● 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 E
brake operation due to extreme drop of fluid viscosity at low
temperature.
F

G
SAT007J

SHIFT CONTROL H
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 the ECM (throttle
opening). This results in improved acceleration performance and fuel economy.
I
Control of Shift Solenoid Valves A and B
The shift solenoid valve performs simple ON-OFF operation. When
set to ON, the drain circuit closes and pilot pressure is applied to the J
shift valve.
The TCM activates shift solenoid valves A and B according to sig-
nals from the ECM (throttle opening) and revolution sensor to select
the optimum gear position on the basis of the shift schedule memo- K
rized in the TCM.

Control of Shift Valves A and B

SAT009J

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.
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
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 lock-up piston.
Conditions for Lock-up Operation
When vehicle is driven in 3rd or 4th gear positions, 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.
Selector lever D position 3rd position
Gear position D4 D3
Vehicle speed sensor More than set value
ECM (throttle opening) Less than set opening
Closed throttle position signal OFF
A/T fluid temperature sensor More than 40°C (104°F)

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
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.

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- I
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 J
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. K

OVERRUN CLUTCH CONTROL (ENGINE BRAKE CONTROL)
Forward one-way clutch is used to reduce shifting shocks in downshifting operations. This clutch transmits
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.

Overrun Clutch Solenoid Valve Control

The overrun clutch solenoid valve is operated by an ON-OFF signal
transmitted by the TCM to provide overrun clutch control (engine
brake control).
When this solenoid valve is ON, the pilot pressure drain port closes.
When it is OFF, the drain port opens.
During the solenoid valve ON pilot pressure is applied to the end
face of the overrun clutch control valve.

SAT015J

AT-36
 OVERALL SYSTEM
[RE4F04B]
Overrun Clutch Control Valve Operation
When the solenoid valve is ON, pilot pressure is applied to the over- A
run clutch control valve. This pushes up the overrun clutch control
valve. The line pressure is then shut off so that the clutch does not
engage. B
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 AT
clutch to engage.
In the 1st position, the overrun clutch control valve remains pushed
down so that the overrun clutch is engaged at all times. D

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION PFP:00000
A
Introduction UCS000MO

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

The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM (transmission B
control module) in combination 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 A/T CHECK indicator lamp. The malfunction is
stored in the TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For details, AT
refer to AT-39, "OBD-II Function for A/T System" .
OBD-II Function for A/T System UCS000MP
D
The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system. One function
is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is sent to the
ECM when a malfunction occurs in the corresponding OBD-related part. The other function is to indicate a E
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. F

One or Two Trip Detection Logic of OBD-II UCS000MQ

ONE TRIP DETECTION LOGIC

G
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 H
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, I
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.

The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
M
OBD-II Diagnostic Trouble Code (DTC) UCS000MR

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.

AT-39
 ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
[RE4F04B]
A sample of CONSULT-II display for DTC and 1st trip DTC is shown
in the following page. DTC or 1st trip DTC of a malfunction is dis-
played in “SELF DIAGNOSIS” mode for “ENGINE” with CONSULT-
II. Time data indicates how many times the vehicle was driven after
the last detection of a DTC.

SAT014K

If the DTC is being detected currently, the time data will be “0”.

SAT015K

If a 1st trip DTC is stored in the ECM, the time data will be “1t”.

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
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
or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
details, refer to EC-56, "FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA" .
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 fol-
lowing priorities to update the data.
Priority Items
1 Misfire — DTC: P0300 - P0306
Freeze frame data Fuel Injection System Function — DTC: P0171, P0172, P0174, P0175

noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is G
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- H
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 I
– 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). J

 TROUBLE DIAGNOSIS - INTRODUCTION
[RE4F04B]
TROUBLE DIAGNOSIS - INTRODUCTION PFP:00000
A
Introduction UCS000MV

The TCM receives a signal from the vehicle speed sensor, ECM
(throttle opening) or park/neutral position (PNP) switch and provides B
shift control or lock-up 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 OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capa- AT
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions 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, F
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only, may not find the cause of the problems. A road G
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the “Work Flow”. Refer to AT-63, "Work Flow" .
H

SAT632I

I
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 J
what conditions they occur. A “DIAGNOSTIC WORKSHEET” like the
example on page AT-61 should be used.
Start your diagnosis by looking for “conventional” problems first. This K
will help troubleshoot driveability problems on an electronically con-
trolled engine vehicle.
Also check related Service bulletins for information. L

A/T Fluid Cooler Cleaning UCS0015J

Whenever an automatic transaxle is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
A/T FLUID COOLER CLEANING PROCEDURE
1. Position an oil pan under the automatic transaxle's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE PFP:31940

Description UCS000OI

The torque converter clutch solenoid valve is activated, with the gear
in D4 , by the TCM in response to signals sent from the vehicle
speed and the ECM (throttle opening). Lock-up piston operation will
then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up
condition, the engine speed should not change abruptly. If there is a
big jump in engine speed, there is no lock-up.

Description UCS000OO

● This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.

● This malfunction will not be detected while the A/T check (position) indicator lamp is indicating another B
self-diagnosis malfunction.
● This malfunction is detected when the A/T does not shift into fourth gear position or the torque converter
clutch does not lock up as instructed by the TCM. This is not caused by electrical malfunction (circuits AT
open or shorted) but by mechanical malfunction such as control valve sticking, improper solenoid valve
operation, malfunctioning oil pump or torque converter clutch, etc.
CONSULT-II REFERENCE VALUE IN DATA MONITOR MODE D
Remarks: Specification data are reference values.
Monitor item Condition Specification

Torque converter clutch

Lock-up OFF Approximately 4% E
↓ ↓
solenoid valve duty
Lock-up ON Approximately 94%

On Board Diagnosis Logic UCS000OP F

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 G
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes H
If the actual gear position is much lower than the position (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve B is stuck closed.
Gear positions supposed by TCM are as follows. I
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve B stuck closed: 1, 2, 2 and 1* positions to each gear position
above J
*: P0744 is detected.
Diagnostic trouble code A/T TCC S/V FNCTN with CONSULT-II or P0744 without CONSULT-II is detected
when A/T cannot perform lock-up even if electrical circuit is good.

Description UCS000PO

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
● Park/neutral position (PNP) switch
The park/neutral (PNP) switch assembly includes a transmission range switch. The transmission range
switch detects the selector lever position and sends a signal to the TCM.
● 3rd position switch
Detects the A/T selector lever in 3rd position and sends a signal to the TCM.
● Throttle position sensor [accelerator pedal position (APP) sensor]
The throttle position sensor [accelerator pedal position (APP) sensor] is part of the system that controls
the throttle position. This system also uses an electric throttle control actuator, which consists of a throttle
control motor and throttle position sensors. Accelerator pedal position signal is sent to the ECM.

Description UCS000R3

● The electrical key interlock mechanism also operates as a shift lock:

With the key switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other posi-
tion unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.
● The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” UCS000ST

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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.
● 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.
● 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.
Precautions for On Board Diagnostic (OBD) System of A/T and Engine UCS000SU

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:
● Be sure to turn the ignition switch “OFF” and disconnect the negative battery cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MIL to light up.
● 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
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.
● Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.

Precautions UCS000SW

NOTE:
Do not remove or disassemble any RE5F22A model transaxle parts unless specified to do so in AT
section.
● Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch “OFF” and disconnect negative
battery cable. 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.

SEF291H

● Before replacing TCM, perform TCM input/output signal

inspection and make sure whether TCM functions properly
or not. AT-448, "TCM INSPECTION TABLE".

MEF040DA

● After performing each TROUBLE DIAGNOSIS, perform

“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
The DTC should not be displayed in the “DTC CONFIRMA-
TION PROCEDURE” if the repair is completed.

SEF217U

● Always use the specified brand of A/T fluid. Refer to MA-10, "Fluids and Lubricants" .
● Use paper rags not cloth rags during work.
● After replacing the A/T fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.

 PRECAUTIONS
[RE5F22A]
Service Notice or Precautions UCS000SX

ATF COOLER SERVICE A

If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T oil cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. Check Service Bullitens for latest A/T oil cooler cleaning pro- B
cedure. For radiator replacement, refer to CO-10, "RADIATOR"
OBD-II SELF-DIAGNOSIS
● A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through AT
the blinking pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table
on AT-452, "SELF-DIAG RESULT 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- D
ories.
Always perform the procedure on AT-419, "HOW TO ERASE DTC" to complete the repair and
avoid unnecessary blinking of the MIL. E
● For details of OBD-II, refer to EC-50, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
● Certain systems and components, especially those related to OBD, may use the new style slide-
locking type harness connector. For description and how to disconnect, refer to PG-61, "HAR- F
NESS CONNECTOR" .

CAN Communication UCS000T6

SYSTEM DESCRIPTION L
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 M
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.
For details, refer to LAN-8, "CAN COMMUNICATION" .

Line Pressure Control UCS000T8

● The pressure control solenoid A controls linear line pressure by control signal from TCM and line pressure
for clutches and brakes to reduce shift shock.
● This pressure control solenoid A controls the pressure regulator valve as the signal pressure and adjusts
the pressure of the operating oil discharged from the oil pump to the line pressure most appropriate to the
driving state.

SCIA2605E

LINE PRESSURE CONTROL IS BASED ON THE TCM LINE PRESSURE CHARACTERISTIC

PATTERN
In order to obtain the most appropriate line pressure characteristic to meet the current driving state, the TCM
controls the pressure control solenoid A current valve and thus controls the line pressure.
Shift Control UCS000T9

The clutch pressure control solenoid is controlled by the signals from the switches and sensors. Thus, the
clutch pressure is adjusted to be appropriate to the engine load state and vehicle driving state. It becomes
possible to finely control the clutch hydraulic pressure with high precision and a smoother shift change charac-
teristic is attained.

SCIA2610E

Basically TCM programmed for economy mode, but TCM changes to several shift schedule automatically
according to specified condition.

SPECIAL SHIFT MODE
Upslope Mode A
When TCM detects upslope from load of engine torque and decrease of acceleration, this mode changes shift
points in high-speed side according to the upslope degree and avoids busy shift of A/T.
B
Downslope Mode
When TCM detects downslope from increase of acceleration with accelerator full close, this mode operates
moderate engine brake by changing shift points in high-speed side.
AT
Hot Mode Control
This control lowers ATF temperature by changing shift points when the temperature is extremely high.
MANUAL MODE D
Driver oneself can select favorite gear and enjoy sports driving of manual transmission sense by shifting lever
from D position to manual mode position and + (up shift) / - (down shift). But lock-up control is operated auto-
matically. Shift control is operated again by shifting from manual gear position to D position. Following control E
is operated when manual mode.
Automated Up Shift Control
F
In order to avoid the over speed of the engine, up shift operate automatically, if it becomes over a constant
vehicle speed.
Automated Down Shift Control G
In order to avoid the stall of the engine, down shift operate automatically, if it becomes under a constant vehi-
cle speed.
Up Shift Permission Control H
In order to avoid the stall of the engine, up shift is done only at over a constant vehicle speed.
Down Shift Permission Control I
In order to avoid the over speed of the engine, down shift is done only at under a constant vehicle speed.
UP/DOWN SHIFT LEARNING CONTROL
This control learns the pressure to each clutch or brake in order to reduce shifting shock at each shifting (Up, J
Down, Manual down, Coast down).
N-D SHIFT CONTROL
K
This control improves the N-D shift quality due to controlling line pressure solenoid valve according to forward
clutch piston stroke learned in N-D shift learning control and applying best hydraulic pressure to forward clutch
at N-D shift.
L
N-D SHIFT LEARNING CONTROL
This control learns the forward clutch hydraulic pressure due to monitoring a forward clutch engaging time and
a rotation change rate.

N-R SHIFT CONTROL
This control improves the N-R shift quality due to controlling shift pressure solenoid valve according to direct
clutch piston stroke learned in N-R shift learning control and applying best hydraulic pressure to direct clutch
at N-R shift.
N-R SHIFT LEARNING CONTROL
This control learns the direct clutch hydraulic pressure due to monitoring a direct clutch engaging time and a

Lock-up Released
● In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the
pressure control solenoid valve C and the lock-up apply pressure is drained.
In this way, the torque converter clutch piston is not coupled.
Lock-up Applied
● In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
pressure control solenoid valve C and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.

SMOOTH LOCK-UP CONTROL
When shifting from the lock-up released state to the lock-up applied state, the current output to the pressure A
control solenoid valve C is controlled with the TCM. In this way, when shifting to the lock-up applied state, the
torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Half-Clutched State B
● The current output from the TCM to the pressure control solenoid valve C is varied to steadily increase the
pressure control solenoid valve C pressure.
In this way, the lock-up apply pressure gradually rises and while the torque converter clutch piston is put AT
into half-clutched status, the torque converter clutch piston operating pressure is increased and the cou-
pling is completed smoothly.
Slip Lock-up Control D
● In the slip region, the pressure control solenoid valve C current is controlled with the TCM to put it into the
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed.
This raises the fuel efficiency for 4th and 5th gears at both low speed and when the accelerator has a low E
degree of opening.

 ON BOARD DIAGNOSTIC (OBD) SYSTEM
[RE5F22A]
ON BOARD DIAGNOSTIC (OBD) SYSTEM PFP:00028

Introduction UCS000TD

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

The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination
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 A/T CHECK indicator lamp. The malfunction is
stored in the TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For detail,
refer to AT-452, "SELF-DIAG RESULT MODE" .
OBD-II Function for A/T System UCS000TE

The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system. One function
is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is sent to the
ECM when a malfunction occurs in the corresponding OBD-related part. The other function 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 OBD-II UCS000TF

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. — 1st Trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MIL will illuminate. — 2nd Trip
The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
OBD-II Diagnostic Trouble Code (DTC) UCS000TG

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 etc.
These DTC 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, CONSULT-II (if available) is recom-
mended.
A sample of CONSULT-II display for DTC and 1st trip DTC is shown
on the next page. DTC or 1st trip DTC of a malfunction is displayed
in SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with CON-
SULT-II. Time data indicates how many times the vehicle was driven
after the last detection of a DTC.

If a 1st trip DTC is stored in the ECM, the time data will be “1t”.

G
SAT016K

Freeze Frame Data and 1st Trip Freeze Frame Data H

The ECM has a memory function, which stores the driving condition such as fuel system status, calculated
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, I
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II
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-56, "FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA" . J
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
K
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 fol-
lowing priorities to update the data.

Both 1st trip freeze frame data and freeze frame data (along with the DTC) 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 cable 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 OBD-II. For details, refer to EC-51, "Emission-related Diagnostic Information" .

Fail-Safe UCS000TJ

The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is a malfunc-
tion in a main electronic control input/output signal circuit.
In fail-safe mode, a driving condition is selected according to the malfunctioning location, and line pressure is
set at the maximum. For this reason, the customer will be subjected to uncomfortable “slipping” or “poor accel-
eration” of the vehicle.
In that case, handle according to the “diagnostics flow” (Refer to AT-426 ).
FAIL-SAFE FUNCTION
If any malfunction occurs in a sensor or solenoid, this function controls the A/T to make driving possible.
NOTE:
Line pressure is set at the maximum in fail-safe mode. Although gear position differs depending on
the type of fail-safe modes, CONSULT-II indicates “5th”.

How To Perform Trouble Diagnosis For Quick and Accurate Repair UCS000TK

INTRODUCTION
The TCM receives a signal from the vehicle speed signal, throttle position sensor (accelerator pedal position
sensor) or PNP switch and provides shift control or lock-up control via A/T solenoid valves.

AT-424
 TROUBLE DIAGNOSIS
[RE5F22A]
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the A
A/T system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
B
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. AT

SAT631IB

D
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful E
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II (or GST) or a circuit tester connected should be F
performed. Follow the AT-426, "WORK FLOW" .

G
SAT632I

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

customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under I
what conditions they occur. A “Diagnostic Worksheet” as shown on
the example (Refer to AT-427 ) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
J
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.

WORK FLOW
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
Make good use of the two sheets provided, “Information From Customer” (Refer to AT-427 ) and “Diagnostic
Worksheet” (Refer to AT-427 ), to perform the best troubleshooting possible.

3. CHECK SHIFT-UP D2 → D3
Press the accelerator pedal down all the way and inspect whether or not the transaxle shifts up (D2 → D3) at
the correct speed.
● Refer to AT-441 .
With CONSULT-II
Read the gear position, accelerator angle and vehicle speed.
Does the A/T shift-up D2 → D3 at the correct speed?
Yes >> GO TO 4.
No >> Enter a check mark at “Vehicle does not shift D2 → D3” on the diagnostics worksheet, then con-
tinue the road test.

4. CHECK SHIFT-UP D3 → D4 AND ENGINE BRAKE

When the transaxle changes speed D2 → D3, return the accelerator pedal.
Does the A/T shift-up D3 → D4 and apply the engine brake?
Yes >> 1. Stop the vehicle.
2. Go to Cruise test - Part 3 (Refer to AT-440 ).
No >> Enter a check mark at “Vehicle does not shift D3 → D4” on the diagnostics worksheet, then con-
tinue the road test.

1. MANUAL MODE FUNCTION

Move to manual mode from D position.
Does it switch to manual mode?
Yes >> GO TO 2.
No >> Continue road test and add check mark to “Cannot be changed to manual mode” on diagnostics
worksheet.

2. CHECK SHIFT-DOWN
During manual mode driving, is downshift from M5 → M4 → M3 → M2 → M1 performed?
With CONSULT-II
Read the gear position.
Is downshifting correctly performed?
Yes >> GO TO 3.
No >> Enter a check mark at “Vehicle does not shift” at the corresponding position (5th → 4th, 4th → 3rd,
3rd → 2nd, 2nd → 1st) on the diagnostics worksheet, then continue the road test.

CONSULT-II UCS000TY

After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” (Refer to AT-452 ), place check
marks for results on the AT-427, "DIAGNOSTIC WORKSHEET" . 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. Display of solenoid valves on CONSULT-II changes at the start of shifting, while gear position is displayed
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.

Description UCS000U0

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 malfunction detection ability. B
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 con-
nected 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. AT

is good.
DESCRIPTION
● Park/neutral position (PNP) switch
The park/neutral (PNP) switch assembly includes a transmission range switch. The transmission range
switch detects the selector lever position and sends a signal to the TCM.
● Stop lamp switch signal
Detects the brake pedal state (stop lamp switch is ON or OFF) and sends a signal via CAN communica-
tion line to the TCM.
● Closed throttle position signal
ECM judges throttle opening based on a signal from accelerator pedal position sensor, and sends the sig-
nal via CAN communication line to TCM.
DIAGNOSTIC PROCEDURE

A/T SHIFT LOCK SYSTEM PFP:34950

Description UCS00118

● The electrical key interlock mechanism also operates as a shift lock:

With the key switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other posi-
tion unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.
● The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.
