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 harness crimping, connector damage

or bent terminals.

NOTE: The illustration shows the side impact sensor (RH).
The position of the side impact sensor (LH) is symmetrical 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 steering column shaft shock absorbing

mechanism (Refer to GROUP 37, On-Vehicle Service

−

Steering Column Shaft Assembly Shock Absorbing
Mechanism Check ).

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 wiring
harness)

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

°C (194° F) or more

•

If the SRS components are removed for the purpose of inspection, sheet metal repair,
painting, etc., they should be stored in a clean, dry place until they are reinstalled.

If the SRS components are to be removed or replaced as a result of maintenance, diagnosis, etc., follow the
appropriate procedure in this section. (Front impact sensor: refer to

P.52B-231
