PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" UCS005D7
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:
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.
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.
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.
Precautions for On Board Diagnostic (OBD) System of CVT and Engine UCS005DA
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:
G Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid valves, 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,
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.
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 EVAP system or fuel injection system,
etc.
G Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precautions for TCM and CVT Assembly Replacement UCS005DB
When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the TCM if
necessary.
CAUTION:
G 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.)
G "TCM POWER SUPPLY [P1701]" may be indicated soon after replacing TCM or CVT assembly
(after erasing the memory). Restart the self-diagnosis after erasing the self-diagnosis result.
Check that no error is detected.

A
Not required because the EEPROM in the TCM is in

first.) B
Not required because the EEPROM in the TCM is in

METHOD FOR ERASING THE EEPROM IN THE TCM
1. Connect CONSULT-II to data link connector. Refer to GI-37, "CONSULT-II Start Procedure" .
2. Turn ignition switch ON. Confirm that CONSULT-II is turned ON. E
3. Move selector lever to "R" position.
4. Touch "START (NISSAN BASED VHCL)" on CONSULT-II.
F
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 G
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".
H
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 I
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. J
2. Move selector lever to "P" position.
3. Turn ignition switch ON.
