PRECAUTIONS

PFP:00001

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

ECS008AD

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

ECS0082F

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

Precautions for A/T Assembly Replacement

ECS0082G

CAUTION:

Check data (Unit ID) in TCM with data monitor of CONSULT-II before replacing A/T assembly or
control valve assembly.

Check if new data (Unit ID) are entered correctly after replacing A/T assembly or control valve
assembly and erasing data in TCM.

When replacing A/T assembly, control valve assembly or TCM, refer to the pattern table below and erase
the EEPROM in the TCM if necessary.

EEPROM ERASING PATTERNS

METHOD FOR ERASING THE EEPROM IN THE TCM

1.

Connect CONSULT-II to data link connector.

2.

Turn ignition switch “ON” position. Confirm that CONSULT-II turn “ON”.

3.

Move selector lever in “R” position.

4.

Touch “START” on CONSULT-II.

5.

Select “SELF-DIAG RESULTS” mode for “A/T” with CONSULT-II. 

6.

Fully press the accelerator pedal (8/8 throttle), and hold it in the fully open position. (This will set the
closed throttle position signal to “OFF”.)

7.

Touch “ERASE” on CONSULT-II, and then touch “YES”.

8.

Wait 3 seconds and then release the accelerator pedal.

9.

Turn ignition switch “OFF” position.

METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSMISSION

In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the
TCM.

1.

With the EEPROM in the TCM erased.

2.

Move selector lever in “P” position.

3.

Turn ignition switch “ON” position.

CHECK METHOD

Normal: About 2 seconds after the ignition switch “ON” position, the A/T CHECK indicator lamp lights up
for 2 seconds.

Abnormal: Even after the ignition switch “ON” position, the A/T CHECK indicator lamp does not light up
after 2 seconds or illuminates immediately.

Cope for abnormal

Replace the control valve assembly.

Replace the TCM.
