Sensor, Impact: Installation: 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, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, 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.
The front and side impact sensors are interchangeable.
- Position the right or left front impact sensor (3) into the engine compartment.
- Connect the engine compartment wire harness connector (2) to the sensor connector receptacle.
- Carefully position the sensor onto the back (engine compartment side) of the front end module carrier (1) inboard of the right or left headlamp. Be certain that the anti-rotation pin on the back of the sensor is engaged in the clearance hole of the carrier.
- Install and tighten the screw (4) that secures the sensor to the back of the carrier. Tighten the screw to 8 N.m (70 in. lbs.).
- Do not connect the negative cable to the battery at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to STANDARD PROCEDURE .
