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 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.
Front impact sensors are used only on light duty models (DS).
- Disconnect and isolate the negative cable from the battery. Wait two minutes for the system capacitor to discharge before further service.
- Raise and support the vehicle.
- Remove the lower radiator cover from the Front End Module (FEM). Refer to RADIATOR, ENGINE COOLING, REMOVAL .
- Locate the front impact sensor (3) on the back of the lower horizontal support (1) of the FEM (also known as the lower radiator cross member). One is near each side of the cooling module.
- Disconnect the FEM wire harness connector (4) from the right or left sensor connector receptacle.
- Remove the screw (2) that secures the sensor to the back of the right or left end of the FEM lower horizontal support.
- Disengage the locating pin integral to the sensor from the locating hole in the FEM lower horizontal support.
- Remove the right or left front impact sensor from the vehicle.
