a. Check a diagnostic system. *
b. Do a visual check which includes the following items with the steering wheel pad (with airbag) removed from the vehicle.
- Check the deformation on the horn button contact plate of the steering wheel.
- Check the damage on the spiral cable connector and wire harness.
CAUTION: Be sure to follow the correct procedure, for removal and installation of the steering wheel pad.
HINT:
- If the horn button contact plate of the steering wheel is deformed, never repair it. Always replace the steering wheel assembly with a new one.
- There should be no interference between the steering wheel pad and steering wheel, and the clearance should be uniform all the way around when the new steering wheel pad is installed on the steering wheel.
* Refer to Air Bag Systems; Testing and Inspection.
REPLACEMENT
CAUTION: Be sure to follow the correct procedure for removal and Installation of the steering wheel pad.
AIRBAG HARNESS
HINT: The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in the system are a standard yellow color.
1. VEHICLES NOT INVOLVED IN COLLISION
Check a diagnostic system. *
2. VEHICLES INVOLVED IN COLLISION
a. Check a diagnostic system. *
b. Check the breakage in all wires of the SRS wire harness, and exposed conductors.
c. Check to see if the SRS wire harness connectors are cracked or chipped.
* Refer to Air Bag Systems; Testing and Inspection.
REPLACEMENT
In the following cases, replace the wire harness or connector.
- If any part of the SRS wire harness or any connector has been found to be faulty in troubleshooting.
- If any part of the SRS wire harness or any connector has been found to be faulty during checking items.
CAUTION: If the wire harness used in the SRS is damaged, replace the whole wire harness assembly.
AIRBAG SENSOR ASSEMBLY
1. VEHICLE NOT INVOLVED IN COLLISION
Check a diagnostic system. *
2. VEHICLE INVOLVED IN COLLISION WITH AIRBAG NOT DEPLOYED
Check a diagnostic system. *
3. VEHICLE INVOLVED IN COLLISION WITH AIRBAG DEPLOYED
Replace the airbag sensor assembly.
* Refer to Air Bag Systems; Testing and Inspection.
REPLACEMENT
In the following cases, replace the airbag sensor assembly.
- If the SRS has been deployed in a collision.
- If the airbag sensor assembly has been found to be faulty in troubleshooting.
- If the airbag sensor assembly has been dropped.
CAUTION: Be sure to follow the correct procedure for removal and Installation of the airbag sensor assembly.
AIRBAG SENSOR FRONT
1. VEHICLES NOT INVOLVED IN COLLISION
Check a diagnostic system. *
2. VEHICLES INVOLVED IN COLLISION
