Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A
BELT PRE-TENSIONER"
ECS00CLV
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 air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
AT
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
D
G 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
G 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
G 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
ECS00AVR
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: G 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, I etc. Will cause the MIL to light up.
G 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.)
G 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
G 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.
G Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and L ECM before returning the vehicle to the customer.

PRECAUTIONS
Precautions
ECS00AVS
NOTE: If any malfunctions occur in the RE5R05A model transmission, replace the entire transmission assembly.
G Before connecting or disconnecting the TCM harness connector, turn ignition switch "OFF" and disconnect negative battery cable. Because battery voltage is applied to TCM even if ignition switch is turned "OFF".
G After performing each TROUBLE DIAGNOSIS, perform "DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE". If the repair is completed the DTC should not be displayed in the "DTC CONFIRMATION PROCEDURE".
SEF289H
SEF217U
G Always use the specified brand of ATF. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" .
G Use paper rags not cloth rags during work.
G After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
G Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
G Disassembly should be done in a clean work area.
G Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere with the operation of the transmission.
G Place disassembled parts in order for easier and proper assembly.
G All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
G Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
G It is very important to perform functional tests whenever they are indicated.
G 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.
G 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.
G Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

PRECAUTIONS
Service Notice or Precautions
ATF COOLER SERVICE
ECS00AVT
A
G If A/T fluid contains fictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines with cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, B refer to AT-14, "A/T Fluid Cooler Cleaning" . For radiator replacement, refer to CO-14, "REMOVAL" .
CHECKING AND CHANGING A/T FLUID
G Increase ATF oil temperature to 80°C (176°F) first, then check and adjust oil level at 65°C (149°F).
AT
NOTE: The A/T has both water cooling and air cooling systems. The air cooling system has a bypass valve. When ATF oil temperature is at or below 50°C (122°F), it does not flow through the air cooled system. If A/ D T oil level is adjusted without flow throughout the entire system, the level will be 10mm lower than required. Therefore, all piping should be filled with oil when adjusting level.
OBD-II SELF-DIAGNOSIS
E
G A/T self-diagnosis is performed by the TCM in combination with the ECM. Refer to the table on AT-89,
"SELF-DIAGNOSTIC RESULT MODE" for the indicator used to display each self-diagnostic result.
G The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem- F
ories.
Always perform the procedure on AT-42, "HOW TO ERASE DTC" to complete the repair and avoid
unnecessary blinking of the MIL.
G
For details of OBD-II, refer to AT-41, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
G Certain systems and components, especially those related to OBD, may use the new style slidelocking type harness connector. For description and how to disconnect, refer to PG-72, "HAR- H NESS CONNECTOR" .

A/T Fluid Cooler Cleaning
ECS00AVZ
Whenever an automatic transmission 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 contaminate 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 transmission's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the steel cooler tubes or bypass valve.
NOTE: Replace the cooler hoses if rubber material from the hose remains on the tube fitting.
4. Allow any A/T fluid that remains in the cooler hoses to drain into the oil pan.

CAN Communication
SYSTEM DESCRIPTION
ECS00AW4
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. For details, refer to LAN-25, "CAN COMMUNICATION" .

During shift change The necessary and adequate line pressure for shift change is set. For this reason, line pressure pattern setting corresponds to input torque and gearshift selection. Also, line pressure characteristic is set according to engine speed, during engine brake operation.
At low fluid temperature
When the A/T fluid temperature drops below the prescribed temperature, in order to speed up the action of each friction element, the line pressure is set higher than the normal line pressure characteristic.

A/T CONTROL SYSTEM
Lock-up applied G In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
torque converter clutch solenoid 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 torque converter clutch solenoid 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 G The current output from the TCM to the torque converter clutch solenoid is varied to gradually increase
the torque converter clutch solenoid pressure. In this way, the lock-up apply pressure gradually rises and while the torque converter clutch piston is put into half-clutched status, the torque converter clutch piston operating pressure is increased and the coupling is completed smoothly.
Slip lock-up control G In the slip region, the torque converter clutch solenoid 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 degree of opening.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOSTIC (OBD) SYSTEM Introduction
PFP:00028
A
ECS00AWB
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 B 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, AT refer to AT-89, "SELF-DIAGNOSTIC RESULT MODE" .
OBD-II Function for A/T System
ECS00AWC
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
ECS00AWD
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. -- 1st 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. -- 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)
J
ECS00AWE
HOW TO READ DTC AND 1ST TRIP DTC
DTC and 1st trip DTC can be read by the following methods.
K
( with CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0720 etc.
These DTC are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
L
G 1st trip DTC No. is the same as DTC No.
G 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.
M
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 CONSULT-II. Time data indicates how many times the vehicle was driven after the last detection of a DTC.

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 detail, refer to AT-41, "ON BOARD DIAGNOSTIC (OBD) SYSTEM" . 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.

HOW TO ERASE DTC The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as described following.
G If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours. G 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-49, "EMISSION-RELATED DIAGNOSTIC INFORMATION ITEMS" . G Diagnostic trouble codes (DTC) G 1st trip diagnostic trouble codes (1st trip DTC)

Fail-Safe
ECS00AWH
The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is an error in a E
main electronic control input/output signal circuit.
In fail-safe mode the transmission is fixed in 2nd, 4th, or 5th (depending on the breakdown position), so the
customer should feel "slipping" or "poor acceleration".
F
Even when the electronic circuits are normal, under special conditions (for example, when slamming on the
brake with the wheels spinning drastically and stopping the tire rotation), the transmission can go into fail-safe
mode. If this happens, switch "OFF" the ignition switch for 10 seconds, then switch it "ON" again to return to the normal shift pattern. Therefore, the customer's vehicle has returned to normal, so handle according to the G
"diagnostics flow" (Refer to AT-48, "WORK FLOW" ).
FAIL-SAFE FUNCTION
H If any malfunction occurs in a sensor or solenoid, this function controls the A/T to make driving possible.
Vehicle Speed Sensor
G Signals are input from two systems - from vehicle speed sensor A/T (revolution sensor) installed on the I
transmission and from combination meter so normal driving is possible even if there is a malfunction in
one of the systems. And if vehicle speed sensor A/T (revolution sensor) has unusual cases, 5th gear and
manual mode are prohibited.
J
Accelerator Pedal Position Sensor
G If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according to a pre-determined accelerator angle to make driving possible. And if there are malfunctions in tow K systems, the engine speed is fixed by ECM to a pre-determined engine speed to make driving possible.
Throttle Position Sensor G If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM accord- L
ing to a pre-determined accelerator angle to make driving possible. And if there are malfunctions in tow
systems, the accelerator opening angle is controlled by the idle signal sent from the ECM which is based
on input indicating either idle condition or off-idle condition (pre-determined accelerator opening) in order M to make driving possible.
PNP Switch
G In the unlikely event that a malfunction signal enters the TCM, the position indicator is switched "OFF", the starter relay is switched "OFF" (starter starting is disabled), the back-up lamp relay switched "OFF" (backup lamp is OFF) and the position is fixed to the "D" range to make driving possible.
Starter Relay G The starter relay is switched "OFF". (Starter starting is disabled.)

TROUBLE DIAGNOSIS
How To Perform Trouble Diagnosis For Quick and Accurate Repair
INTRODUCTION
ECS00AWI
A
The TCM receives a signal from the vehicle speed sensor, accelerator pedal position sensor (throttle position
sensor) or PNP switch and provides shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
B
sent from sensing elements used with the OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store malfunctions in its memory.
AT
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-
D
tion, etc.
SAT631IB
E
It is much more difficult to diagnose a error that occurs intermittently
rather than continuously. Most intermittent errors are caused by poor
F
electric connections or improper wiring. In this case, careful check-
ing 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
G
with CONSULT-II (or GST) or a circuit tester connected should be
performed. Follow the AT-48, "WORK FLOW" .
H
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 errors, especially intermittent ones. Find out what symptoms are present and under what conditions they occur. A "Diagnostic Worksheet" as shown on the example (Refer to AT-49 ) should be used. Start your diagnosis by looking for "conventional" errors first. This will help troubleshoot driveability errors on an electronically controlled engine vehicle. Also check related Service bulletins.

"NG".
H
ECU PART NUMBER
TCM part number can be read.
CONSULT-II REFERENCE VALUE
I
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 J
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- K
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
L
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).

DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE Description
PFP:23710
A
ECS00AWY
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.

NOTE: Following procedure will cover both column and floor shift selector levers. 1. Place selector lever in "P" position, and turn ignition switch ON
(engine stop). 2. Make sure selector lever can be shifted to other than "P" posi-
tion when brake pedal is depressed. Also make sure selector lever can be shifted from "P" position only when brake pedal is depressed. 3. Move the selector lever and check for excessive effort, sticking, noise or rattle. 4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all the positions. Check whether or not the actual position the selector lever is in matches the position shown by the shift position indicator and the transmission body. 5. The method of operating the lever to individual positions correctly should be as shown in the figure. 6. Confirm the back-up lamps illuminate only when lever is placed in the "R" position. Confirm the back-up lamps does not illuminate when selector lever is pushed against "R" position in the "P" or "N" position. 7.
