Impact Sensor: Description and Operation
IMPACT SENSORSWARNING:The restraints control module (RCM) orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) has been involved in a collision in which the vehicle center tunnel area has been damaged, inspect the RCM mounting and bracket for deformation. If damaged, a new RCM must be installed whether or not the air bags have deployed. In addition, make sure the area of the RCM mounting is restored to its original condition.
All vehicles will have a front impact severity sensor located behind the front radiator grille under the hood latch assembly. There are 2 side impact sensors located on each B-pillar. In addition there are 2 side impact sensors mounted near the driver and passenger C-pillars when the vehicle is equipped with driver and passenger safety canopy modules/seat side air bags. The RCM is mounted on the center tunnel under the instrument panel. Mounting orientation is critical for correct operation of all impact sensors.
