Removal

WARNINGS: Published: 11-May-2011

To avoid accidental deployment, the restraints control module backup power supply must be depleted. Wait at least one
minute after disconnecting the battery ground cable(s) before commencing any repair or adjustment to the supplemental
restraint system (SRS), or any component(s) adjacent to the SRS sensors. Failure to follow these instructions may result in
personal injury.


Always wear safety glasses when working on an air bag equipped vehicle and when handling an air bag module. Failure to
follow this instruction may result in personal injury.


To minimize the possibility of premature deployment, do not use radio key code savers when working on the
supplemental restraint system. Failure to follow this instruction may result in personal injury.


To minimize the possibility of injury in the event of premature deployment, always carry a live air bag module with the
bag and trim cover pointed away from the body. Failure to follow this instruction may result in personal injury.


To minimize the possibility of premature deployment, live air bag modules must only be placed on work benches which
have been ground bonded and with the trim cover facing up. Failure to follow these instructions may result in personal injury.


Never probe the electrical connectors of air bag modules or any other supplemental restraint system component. Failure
to follow this instruction may result in personal injury.


Painting over the driver air bag module trim cover or instrument panel could lead to deterioration of the trim cover and air
bags. Do not for any reason attempt to paint discolored or damaged air bag module trim covers or instrument panel. Install a
new component. Failure to follow this instruction may result in personal injury.
NOTES:


Some variation in the illustrations may occur, but the essential information is always correct.


Removal steps in this procedure may contain installation details.

1. Make the air bag supplemental restraint system (SRS) safe.

Refer to: Standard Workshop Practices (100-00 General Information, Description and Operation).

2. Refer to: Front Seat (501-10 Seating, Removal and Installation).
3. Refer to: Front Safety Belt Buckle (501-20A Safety Belt System, Removal and Installation).

4. Refer to: Front Seat Cushion Cover (501-10 Seating, Removal and Installation).

Safety Information

WARNINGS:


To avoid accidental deployment the back-up power supply must be depleted before beginning any work on the SRS system
or its components. Failure to follow this instruction may result in personal injury


Do not use a multimeter to probe an SRS module. It is possible for the power from the multimeter battery to trigger the
activation of the module. Failure to follow this instruction may result in personal injury


NOTE: Do not to use a cellular phone or to have a cellular phone in close proximity when working on the SRS system or
components
Power supply depletion

Before beginning any work on the SRS system or related components:
1. Remove the ignition key

2. Disconnect the battery leads, ground first

3. Wait 2 minutes for the power circuit to discharge

There are comprehensive instructions on the correct procedures for SRS system repairs, refer to the relevant section of the
workshop manual

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle


NOTE: Check and rectify basic faults before beginning diagnostic routines including pinpoint tests

1. Verify the customer concern by operating the seatbelt

2. Visually inspect for obvious signs of mechanical or electrical damage

Visual Inspection
Mechanical Electrical
Check for the installation of non-standard accessories which may affect or
obstruct the function of the seatbelt system
Frayed or damaged webbing
Missing or damaged button stop
Pretensioner(s) Buckles/Stalks
Fuses

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step

4. If the cause is not visually evident, carry out the test methods described below, alternatively check for diagnostic
trouble codes and refer to the relevant diagnostic trouble code index

For a complete list of all diagnostic trouble codes that could be logged on this vehicle, please refer to section 100-00.

Inertia Reel Seatbelts

The vehicle is equipped with (two row one) and (three row two) inertia reel seatbelts
These seatbelts are "dual sensitive" which means that they have:
Car sense system - A vehicle motion sensor, which locks the seatbelt webbing under braking, cornering, on steep
hills and in adverse camber conditions, when parked on a steep incline or driveway or two wheels on a high curb
Web sense system - A webbing motion sensor, which locks when the seatbelt webbing is extracted suddenly
The seatbelts in the following positions are equipped with an automatic locking retractor function:
