FRONT

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, 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 supplemental restraint system. 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.

NOTE: The front and side impact sensors are interchangeable.





1. Service access for the right front impact sensor is accomplished by removing the air filter housing from the engine compartment. Service access for the left front impact sensor is accomplished by raising and supporting the vehicle, then removing the access plug from the front of the left front wheel house liner.

2. Position the right or left front impact sensor (5) into the engine compartment.

3. Reconnect the jumper wire harness (4) to the right or left front impact sensor connector receptacle or to the body wire harness (2).

4. Position the sensor onto the stud (6) on the back (engine compartment side) of the front end module carrier below and inboard of the front lamp unit park/turn signal bulb socket (1). Be certain that the anti-rotation pin on the back of the sensor is engaged in the clearance notch of the carrier and the connector receptacle is pointed straight downward.

5. Install and tighten the nut (3) that secures the sensor to the stud on the back of the carrier. Tighten the nut to 8 Nm (71 in. lbs.).

6. Do not reconnect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed following service of any supplemental restraint system component.
