Post-Collision Inspection
In deployment collisions, replace air bag inflator module, SIR coil assembly and wiring, and sensors in area of accident damage. In all types of collisions regardless of air bag deployment, visually inspect all the following components and mounting points and replace as required: DERM, knee bolster, instrument panel-to-steering column reinforcing plate and lower brace, any sensor which DERM indicates is bad, steering column, and steering wheel.
Area of accident damage is defined by manufacturer as that area of the vehicle which is crushed, bent, or damaged in other ways. For example, a front-end collision in which the forward portion of the vehicle has contacted another object, sensors on radiator tie bar would require replacement, since that portion of the vehicle was damaged in the accident.
