Sensor, Impact: Removal: Front
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, Occupant Classification System (OCS), 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 follow these instructions may result in accidental airbag deployment.
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 restraints. 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 supplemental restraint deployment.
The front and the side impact sensors are NOT interchangeable.
- Disconnect and isolate the negative cable from the battery. Wait two minutes for the system capacitor to discharge before further service.
- Disconnect the headlamp and dash wire harness connector (3) from the right or left front impact sensor (2) connector receptacle.
- Remove the nut (1) that secures the sensor to the weld stud on the back of the FEM vertical support member (4) just outboard of the upper cooling module mount (5).
- Gently pry the sensor away from the FEM vertical support member far enough to disengage the latch feature of the locator pin on the back of the sensor from the locator hole in the FEM.
- Remove the right or left front impact sensor from the vehicle.
