POST-COLLISION DIAGNOSIS

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-138

AIR BAG MODULES

1. Check the pad cover for dents, cracks or

deformation.

2. Check the connector for damage, terminals

deformities, and the harness for binding.

3. Check the air bag inflator case for dents, cracks or

deformities.

4. Check the air bag modules for proper installation.

CLOCK SPRING

1. Check the clock spring connectors and protective

tube for damage, and the terminals for
deformation.

2. Visually check the case for damage.

FRONT SEATBACK ASSEMBLY
(SIDE-AIRBAG MODULE)

1. Check the side-airbag module deployment section

in the seat for dents and deformation.

2. Check the connectors for damage, the terminals

for deformation, and the harness for binds.

SIDE IMPACT SENSOR

1. Check the centre pillar for deformation or rust.
2. Check the side impact sensors for dents, cracks,

deformation and rust.

3. Check the connector for damage and the

terminals for deformation.
NOTE: The figures show side impact sensors
(LH). The side impact sensors (RH) is symmetri-
cal with the side impact sensors (LH).

CURTAIN AIR BAG MODULES

1. Check that the curtain air bag deployment part of

the headlining is normal.

2. Check the inflator surface for cracks, dents or

deformations.

3. Check the air bag for breakage.
4. Check the connector for damage, the terminal for

deformation and the harness for binding.

STEERING WHEEL, STEERING COLUMN
AND SHAFT ASSEMBLY

1. Check the wiring harness (built into the steering

wheel) and the connectors for damage, and the
terminals for deformation.

2. Install the air bag module to check fit or alignment

with the steering wheel.

3. Check the steering wheel for noise, binding or

difficult operation and excessive free play.

4. Check the steering column shaft shock absorbing

mechanism (Refer to GROUP 37, On-Vehicle
Service

P.37-89

).

SEAT BELT WITH PRE-TENSIONER

1. Check the seat belt for damage or deformation.
2. Check the seat belt with pre-tensioner for cracks

or deformation.

3. Check that the unit is installed correctly to the

vehicle body.

HARNESS CONNECTOR (INSTRUMENT
PANEL WIRING HARNESS AND FLOOR
WIRING HARNESS, ROOF WIRING
HARNESS)

Check harnesses for binding, connectors for damage
and terminals for deformation (Refer to

P.52B-5

).

WARNING

•

Disconnect the negative battery terminal and wait for 60 seconds or more before starting
work. Furthermore, the disconnected battery terminal should be covered with tape to
insulate it.

•

Never attempt to disassemble or repair the front impact sensor. If faulty, replace it.

•

Do not drop or subject the front impact sensor to impact or vibration. If denting, cracking,
deformation, or rust are discovered in the front impact sensor, replace it with a new front
impact sensor. Discard the old one.

•

After deployment of an air bag, replace the front impact sensor with a new one.

NOTE: The figures show front impact sensor (LH).

Pre-removal Operation

• Turn the ignition key to the "LOCK" (OFF) position.

• Disconnect the Negative Battery Terminal.
