PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BCS001NA
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 Necessary for Steering Wheel Rotation After Battery DisconnectBCS001NB
NOTE:
This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

Precautions for TCM and CVT Assembly ReplacementBCS001FR
When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the TCM if
necessary.
CAUTION:
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.)
“TCM POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle assembly
(after erasing the memory). Restart the self-diagnosis after erasing the self-diagnosis result.
Check that no error is detected.
EEPROM ERASING PATTERNS
METHOD FOR ERASING THE EEPROM IN THE TCM
1. Connect CONSULT-II to data link connector. Refer to CVT-45, "CONSULT-II SETTING PROCEDURE" .
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. Press the brake pedal and turn the 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.
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
TCM.
1. Erase the EEPROM in the TCM.
2. Move selector lever to “P” position.
3. Turn ignition switch ON.
CHECK METHOD
Standard: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.
Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds
or illuminates immediately.
CAUTION:
Perform in the “P” or “N” position.
Action for Non-standard
Replace the CVT assembly.
Replace the TCM.
CVT assembly TCM Erasing EEPROM in TCM Remarks
Replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state. (CVT assembly must be replaced
first.)
Not replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state.
Replaced Not replaced RequiredRequired because data has been written in the
EEPROM in the TCM and because the TCM cannot
write data from the ROM assembly in the transmis-
sion.
