Repairs and Inspections Required After a Collision: Service and Repair
Airbag Systems
INSPECTION LOCATIONS AFTER A COLLISION
REPLACEMENT
When airbag system is deployed, replace the following parts.
1. FRONT COLLISION
1. Driver s airbag module
2. Passenger s airbag module
3. Driver s seat belt (pretensioner)
4. Passenger s seat belt (pretensioner)
5. Airbag control module
6. Front sub-sensor
7. Roll connector
2. SIDE COLLISION
1. Airbag control module
2. Side airbag module (operating side seat backrest)
3. Side airbag sensor (operating side)
3. INSPECTION OF OTHER PARTS
Check for the following parts, replace the damaged parts with new ones.
1. Steering wheel and steering shaft Check the steering wheel and steering shaft for mounting condition and deflection of axial and radical,
upward and downward direction. Check the steering shaft for deflection of axial and radical direction with tilt lever released. (After a collision,
absorbing part of steering shaft may inflate.)
2. Check the direct type connector of driver s airbag module, pretensioner, etc. for damage, and also check each harness for pinch and connector
damage. If damage is found, replace the harness as a unit.
3. Check the seat cushion frame, backrest, seat rail and headrest for deformation, distortion, crack, installing condition and play.
4. For passenger's seat, replace the seat cushion pad frame assembly with new one if the seat cushion frame assembly is deformed or cracked.
5. If the passenger's seat cushion cover is torn or frayed, replace the seat cushion cover with a new one. Otherwise, the occupant detection system
may not operate properly.
6. Be sure to perform the system calibration for occupant detection system when the passenger s seat cushion cover has been removed or
replaced. Failure to do so may cause improper activation of occupant detection system.
7. Check if the driver's seat position sensor, and the driver's and passenger's seatbelt buckle switches operate normally.
INSPECTION
If the vehicle is involved in a collision, even if it is a slight collision, be sure to check the following system parts.
1. DRIVER S AIRBAG MODULE
1. Check for the following, and replace damaged parts with new parts.
-
Airbag module is cracked or deformed.
-
Harness and/or connector is cracked, deformed or open. Lead wire is exposed.
-
The module surface is fouled with grease, oil, water or cleaning solvent.
2. When installing a new driver's airbag module, check the following, and replace the damaged parts with new ones.
-
The steering wheel is in the way, making it difficult to install the airbag module.
-
The clearance between the driver's airbag module and steering wheel is not constant.
-
The steering wheel deformation in axial and radial directions exceed limits.
