Impact Sensor: Service and Repair

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, 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.
1. Position the right or left front impact sensor (3) into the engine compartment.
2. Reconnect the headlamp and dash wire harness connector (2) to the sensor connector receptacle.
3. Carefully position the sensor onto the back of the right or left end of the lower radiator crossmember (1). Be certain that the anti-rotation pin on
the back of the sensor is engaged in the clearance hole of the crossmember.
4. Install and tighten the screw (4) that secures the sensor to the back of the crossmember. Tighten the screw to 10 Nm (90 in. lbs.).
5. 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.

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 airbags. 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 supplemental restraint deployment.
