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 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. Remove the screw (4) that secures the impact sensor (3) to the of the right or left radiator support vertical member (2).
3. Disconnect the engine compartment wire harness connector (1) from the right or left front impact sensor connector receptacle.
4. Remove the right or left front impact sensor from the engine compartment.

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 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 side SRS component deployment.
NOTE: The front and side impact sensors are interchangeable.
