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, 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.
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.
- Disconnect and isolate the negative battery cable. Wait two minutes for the system capacitor to discharge before further service.
- Disconnect the headlamp and dash wire harness connector (4) from the front impact sensor (3) connector receptacle.
- Remove the nut (2) that secures the front impact sensor to the bracket and weld stud on the back of the vertical support member (1) just outboard of the cooling module within the engine compartment.
- Disengage the locating and anti-rotation pin of the sensor from the clearance hole in the bracket.
- Remove the front impact sensor from the vertical support member.
