WHEN AIR BAGS DO NOT DEPLOY IN LOW-SPEED
COLLISION.
Check the SRS components. If the SRS components are show-
ing any visible damage such as dents, cracks, or deformation,
replace them with new ones. Concerning parts removed for
inspection, replacement with new parts and cautionary points
for working, refer to appropriate INDIVIDUAL COMPONENT

FRONT IMPACT SENSORS
1. Check the headlight support panel for distortion and rust.
2. Check the front impact sensor for dents, cracks, deformation

or rust.

3. Check the front impact sensor wiring harnesses for binding,

check the connector for damage, and check the terminals
for deformation.

SRS-ECU
1. Check the SRS-ECU case and brackets for dents, cracks or

deformation.

2. Check the connector for damage, and the terminals for

deformation.

3. Check the fit of the SRS-ECU and its bracket.

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. Install the air bag module (driver's side) to the steering

wheel to check fit or alignment with the steering wheel.

5. Install the air bag module (front passenger's side) to the

instrument panel and front deck crossmember to check fit or
alignment.

FRONT SEATBACK ASSEMBLY (SIDE-AIRBAG MODULE)
1. Check that there is no abnormality in the side-airbag module

deployment section.

2. Check that there is no connector damage, bent terminals or

clamping of the harness.

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.

SIDE IMPACT SENSOR
1. Check that there is no bending or corrosion in the center

pillar.

2. Check that there is no denting, breakage or bending of the

side impact sensor.

3. Check that there is no clamping of the harness, connector

damage or bent terminals.
NOTE: The illustration at left shows the side impact sensor
(RH). The position of the side impact sensor (LH) is symmet-
rical to this.

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 collision energy absorbing mechanism on the

steering column shaft (Refer to GROUP 37A, On-vehicle
Service

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 (FRONT WIRING HARNESS,
INSTRUMENT PANEL WIRING HARNESS AND FLOOR

WARNING

•

If heat damage may occur during paint work, remove the SRS-ECU, the air bag modules,
the clock spring, the front seats and the seat belt with pre-tensioner. Recheck the SRS
system operability after reinstalling them (Refer to GROUP 00, Maintenance Service-SRS
