Impact Sensor: Service and Repair

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before
attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service.
Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing
further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental
airbag deployment.
WARNING: To avoid serious or fatal injury, never strike or drop the front impact sensor, as it can damage the impact sensor or affect its
calibration. The front impact sensor enables the system to deploy the front Supplemental Restraint System (SRS) components. If an impact
sensor is accidentally dropped during service, the sensor must be scrapped and replaced with a new unit. Failure to observe this warning could
result in accidental, incomplete, or improper front SRS component deployment.
NOTE: The front and the side impact sensors are interchangeable.
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Disconnect the headlamp and dash wire harness connector (5) from the right or left front impact sensor (2) connector receptacle.
3. Remove the nut (1) that secures the sensor to the stud on the bracket (4) on the back of the right or left radiator support vertical member (3).
4. Remove the right or left front impact sensor from the engine compartment.

is accidentally dropped during service, the sensor must be scrapped and replaced with a new unit. Failure to observe this warning could result
in accidental, incomplete, or improper side SRS component deployment.
