Impact Sensor: Description and Operation
IMPACT SENSORS
WARNING:
-
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 center tunnel area has been damaged, inspect the
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.
-
Vehicle sensor orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system
(SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Install and correctly position a
new sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
For these vehicles, the SRS employs 5 impact sensors. One of the sensors is integral to the RCM and is not separately serviceable. The RCM is mounted
on the center tunnel under the instrument panel. There are 2 front impact severity sensors located in the front-center of the vehicle, behind the grille. In
addition there are 2 side impact sensors. The side impact sensors are located at the base of each B-pillar below the safety belt retractor and pretensioner.
Mounting orientation is critical for correct operation of all impact sensors.
