Air Bag System

REPAIRS AND INSPECTIONS REQUIRED AFTER A COLLISION

FRONT PASSENGER AIRBAG ASSEMBLY

Vehicle not involved in collision

a. Do a diagnostic system check.
b. Do a visual check which includes the following items with the front passenger airbag assembly installed in the vehicle.

Check for cuts, minute cracks or marked discoloration of the front passenger airbag door.

Vehicle involved in collision and airbag is not deployed

a. Do a diagnostic system check.
b. Do a visual check which includes the following items with the front passenger airbag assembly removed from the vehicle.
- Check for cuts and cracks in, or marked discoloration of the front passenger airbag door.
- Check for cuts and cracks in wire harnesses, and for chipping in connectors.

- Check for deformation of the instrument panel and instrument panel reinforcement.

HINT:
- If the instrument panel or instrument panel reinforcement is deformed, never repair it. Always replace it with a new one.

- There should be no interference between the instrument panel and front passenger airbag door, or the glove compartment door and front passenger airbag door. The clearance should be uniform all the way around when the new airbag assembly is installed on the instrument panel.

CAUTION: Be sure to follow the correct procedure, for removal and installation of the front passenger airbag assembly.

Vehicle involved in collision and airbag is deployed

a. Do a diagnostic system check.
b. Do a visual check which includes the following items with the airbag assembly removed from the vehicle.
- Check for deformation of the instrument panel, instrument panel reinforcement and glove compartment door.
- Check for damage to the connector and wire harness.

HINT:
- If the instrument panel or instrument panel reinforcement is deformed, never repair it. Always replace it with a new one.
- There should be no interference between the instrument panel and front passenger airbag door, or the glove compartment and front passenger airbag door. The clearance should be uniform all the way around when the new airbag assembly is installed on the instrument panel.

REPLACEMENT REQUIREMENTS

CAUTION: Be sure to follow the correct procedure, for replacement of the front passenger air bag assembly.

STEERING WHEEL PAD AND SPIRAL CABLE

Vehicle not involved in collision:

INSPECT SUPPLEMENTAL RESTRAINT SYSTEM

a. Do a diagnostic system check.
b. Do a visual check which includes the following item with the steering wheel pad (with airbag) installed in the vehicle.
Check cuts, minute cracks or marked discoloration on the steering wheel pad top surface and in the grooved portion.

Vehicle involved in collision and airbag is not deployed:

INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
a. Do a diagnostic system check.

b. Do a visual check which includes the following items with the steering wheel pad (with airbag) removed from the vehicle.
- Check cuts, minute cracks or marked discoloration on the steering wheel pad top surface and in the grooved portion.
- Check cuts and cracks in wire harness, and chipping in connectors.

- Check the deformation of the horn button contact plate on the steering wheel pad.

HINT:
- If the horn button contact plate of the steering wheel pad is deformed, never repair it. Always replace the steering wheel pad 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.

CAUTION: Be sure to follow the correct procedure, for removal and installation of the steering wheel pad.

Vehicle involved in collision and airbag is deployed:

INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
a. Do a diagnostic system check.
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 pad.
- Check the damage on the spiral cable connector and wire harness.

HINT:
- If the horn button contact plate of the steering wheel pad is deformed, never repair it. Always replace the steering wheel pad with a new one.

CAUTION: Be sure to follow the correct procedure, for removal and installation of the steering wheel pad.

AIRBAG HARNESS

INSPECTION

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
Do a diagnostic system check. *

2. VEHICLES INVOLVED IN COLLISION
a. Do a diagnostic system check. *
b. Check breaks 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 SRS Warning Light Check, and How to Display and Read Diagnostic Codes.

AIRBAG SENSOR ASSEMBLY

VEHICLE NOT INVOLVED IN COLLISION
Check a diagnostic system.

VEHICLE INVOLVED IN COLLISION WITH AIRBAG NOT DEPLOYED
Check a diagnostic system. *

VEHICLE INVOLVED IN COLLISION WITH AIRBAG DEPLOYED
Replace the airbag sensor assembly. *

* Refer to SRS Warning Light Check, and How to Display and Read Diagnostic Trouble Codes.

REPLACEMENT REQUIREMENTS

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: For removal and installation of the airbag sensor assembly. Be sure to follow the correct procedure.

AIRBAG SENSOR FRONT

INSPECTION

1. VEHICLES NOT INVOLVED IN COLLISION
Do a diagnostic system check. *

2. VEHICLES INVOLVED IN COLLISION
a. Do a diagnostic system check. *

b. If the front fender of the car or its periphery is damaged, do a visual check for damage to the front airbag sensor, which includes the following items even if the airbag was not deployed:
- Check the bracket deformation.
- Check the paint peeling off the bracket.
- Check the cracks, dents or chips in the case.
- Check the cracks, dents, chipping and scratches in the connector.
- Check the peeling off of the label or damage to the serial number.

* Refer to SRS Warning Light Check, and How to Display and Read Diagnostic Trouble Codes.

REPLACEMENT REQUIREMENTS
In the following cases, replace the front airbag sensor.
- If the SRS has been deployed in a collision. (Replace both the left and right airbag sensors.)
- If the front airbag sensor has been found to be faulty in troubleshooting.
- If the front airbag sensor has been found to be faulty during checking items.
- If the front airbag sensor has been dropped.

CAUTION: Be sure to follow the correct procedure for removal and installation of the front airbag sensor.
