Impact Sensor - Removal

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 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.
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the two screws (2) that secure the right or left front impact sensor (1) to the back of the right or left radiator support vertical member (4).
3. Disconnect the headlamp and dash wire harness connector (3) from the sensor connector receptacle.
4. Remove the right or left front impact sensor from the engine compartment.

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 side impact sensor, as it can damage the impact sensor or affect its
calibration. The side impact sensor enables the system to deploy the side curtain 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 side supplemental restraint deployment.
NOTE: Side impact sensors are used only on vehicles equipped with the optional side curtain airbags.
