Removal and InstallationBIS0014E
REMOVAL
CAUTION:

Before removing the front seat, turn the ignition switch off, disconnect both battery cables and
wait and least 3 minutes.

When checking the power seat circuit for continuity using a circuit tester, do not confuse its con-
nector with the side air bag module connector. Such an error may cause the air bag to deploy.

Do not drop, tilt, or bump the side air bag module installing in the seat. Always handle it with care.
1. Remove front leg cover and rear leg cover (LH/RH).
2. Remove bolts.
NOTE:
Set seat sliding and seat reclining to center position when disassembling power seat after removing bolts.
Set seat lifter to top position when disassembling.
3. Disconnect side air bag module connector and power seat harness connector under the seat and remove
harness securing clips.
CAUTION:
Before removal, be sure to turn ignition switch OFF, disconnect both battery cables, and then wait
for at least 3 minutes.
4. Remove seat from the vehicle.
CAUTION:
When removing and installing, use shop cloths to protect parts from damage.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Before installation, be sure to turn ignition switch OFF, disconnect both battery cables, and then wait
for at least 3 minutes.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BHS0003U
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 for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceBHS0003V

Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.

Before servicing the SRS, turn ignition switch OFF, and disconnect both battery cables. Then wait at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformations or rust before
installation and replace if required.

The spiral cable must be set to the neutral position since its rotations are limited. Do not attempt to turn
steering wheel or column, if steering gear was disconnected from the column shaft.

Handle air bag module carefully. Always put a driver air bag module with the pad side facing upward.

Conduct self-diagnosis to check entire SRS for proper function after replacing any components.

After an air bag is deployed, the front instrument panel assembly should be replaced if damaged.

Always replace instrument panel pad following front passenger air bag deployment.

TROUBLE DIAGNOSISPFP:00004
Trouble Diagnosis IntroductionBHS00043
CAUTION:

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.

Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.

Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

TROUBLE DIAGNOSIS

Trouble Diagnosis with CONSULT-IIBHS0004A
DIAGNOSTIC PROCEDURE 2
CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

The display of self-diagnostic results in “SELF-DIAG [CURRENT]”, “SELF-DIAG [PAST]” and
“TROUBLE DIAG RECORD” screens of CONSULT-II is limited to 3 items at once. Scroll for 4 or
more screens when checking.
1. Touch “SELF-DIAG [CURRENT]”.
2. Diagnostic code is displayed on “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]” even
though malfunction is detected in “SRS Operation Check”,
check the battery voltage. If the battery voltage is less than 9 V,
charge or replace the battery. Refer to SRS-22, "
DIAGNOSTIC
PROCEDURE 3" . If the battery voltage is OK, refer to SRS-24,
"DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM DIAG-
NOSTIC PROCEDURE 2)" . diagnose the following cases:

Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in
the memory) might not be erased after repair.
