PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" ACS003KX
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:
q 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.
q 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.
q 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 TCM and CVT Assembly Replacement ACS001SA
CAUTION:
q Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-II, and then turn ignition switch OFF.)
q When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.

write data from the ROM assembly in the transmis-
sion.
METHOD FOR ERASING THE EEPROM IN THE TCM
1. Connect CONSULT-II to data link connector.
2. Turn ignition switch ON. Confirm that CONSULT-II is turned "ON".
3. Move selector lever to "R" position.
4. Touch "START (NISSAN BASED VHCL)" on CONSULT-II.
5. Select "SELF-DIAG RESULTS" mode for "TRANSMISSION" with CONSULT-II.
6. Brake switch "ON".
7. Press the accelerator pedal (0.5/8 - 4/8 throttle) not to exceed the half, and hold it in the half or less open
position. (This will set the closed throttle position signal to "OFF" and the wide open throttle position signal
to "OFF".)
8. Touch "ERASE" on CONSULT-II, and then touch "YES".
9. Wait 3 seconds and then release the accelerator pedal.
10. Turn ignition switch OFF.

PRECAUTIONS
METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSAXLE
In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the A
TCM.
1. With the EEPROM in the TCM erased.
2. Move selector lever to "P" position. B
3. Turn ignition switch ON.
CHECK METHOD CVT
q Normal: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.
q Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds
or illuminates immediately. D
CAUTION:
Perform in the P or N position.
Cope for Non-standard E
q Replace the CVT assembly.
q Replace the TCM.
