should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:
• The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
• The seat belt was damaged in an accident. (i.e., torn webbing, bent retractor or guide, etc.)
• The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
• Anchor bolts are deformed or worn out.
• The seat belt pre-tensioner should be replaced even if t he seat belts are not in use during the collision in
which the air bags are deployed.
OCCUPANT CLASSIFICATION SYSTEM
• Replace occupant classification system control uni t and passenger front seat cushion as an assembly.
Refer to SE-51, "
Removal and Installation".
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000005266527
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
• Always use CONSULT-III 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 NATS , an electrically controlled steering lock mech-
anism 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 al l control units using CONSULT-III.

REMOVAL
CAUTION:
• Do not attempt to repair or replace damaged direct-connect SRS component connectors. If a driver air bag direct-connect harness connector is damaged, the spiral cable must be replaced.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• When servicing the SRS, do not work from directly in front of air bag module.
1. Disconnect the negative and positive battery term inals, then wait at least three minutes.
2. Remove the left and right side bolts.
3. Lift the driver air bag module from the steering wheel.
4. Disconnect the air bag harness and horn connectors, then remove the driver air bag module. • For removal/installation of the direct-connect SRS connectors, refer to SRC-9, "
Direct-connect SRS
Component Connectors".
CAUTION:
• When servicing the SRS, do not work from directly in front of air bag module.
• Always place air bag module wi th pad side facing upward.
• Do not insert any foreign object s (screwdriver, etc.) into air
bag module or harness connectors.
• Do not disassemble air bag module.
• Do not use old bolts after removal; replace with new bolts.
• Do not expose the air bag mo dule to temperatures exceeding
90° C (194 °F).

• After installation, turn steering wheel to make sure it moves smoothly. Make sure the number of turns are the same from the straight-forward position to left and right locks. Make sure that the steering wheel is in a neu-
tral position when driving straight ahead.
• When installing steering column to steering mem ber, install nut from front side of vehicle.
INSPECTION AFTER INSTALLATION
• After installing steering column to vehicle, check tilt device operation range is within specification.
• Check if steering wheel operation can turn to the end of the left and right stops smoothly.
