Post-Collision Inspection
Service of Air Bag Equipped Vehicles Involved in CollisionsWhile servicing an air bag equipped vehicle that has been involved in a collision, check the radiator primary crash sensors and wiring.
Sensors
Vehicle sensor orientation is critical for proper air bag system operation. If a vehicle equipped with an air bag system is involved in a crash where the fenders or grille area have been damaged, ensure that body structure in the area of the sensor mounting is restored to its original condition. Inspect the air bag sensor mounting brackets for damage.
- Damaged sensors should be replaced whether or not the air bag is deployed.
- Undamaged sensors will reset automatically after a collision and can be reused.
Damaged Wiring
CAUTION: Before attempting diagnostic prove out, check for wiring shorts that could cause the diagnostic monitor to blow the air bag battery feed fuse, causing unnecessary servicing.
Steering Column and Air Bag Sliding Contact
If the collision involved an air bag deployment, the steering column may have been loaded sufficiently to deform its mounting brackets or damage column wiring. An inspection should be made of the column structure and air bag sliding contact wiring to ensure that any damaged components are replaced.
