Sensor, Impact: Installation: Front
On vehicles equipped with the high voltage system, disconnecting the 12-volt battery negative cable alone will not power down the 12-volt system. You must perform the 12-volt Power Down procedure before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
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.
- Position the right or left front impact sensor (1) into the engine compartment.
- Reconnect the headlamp and dash wire harness connector (4) to the sensor connector receptacle.
- Carefully position the sensor. On the right side only, the sensor is secured to an adapter bracket that is fastened to the back of the FEM support structure. On the left side the sensor is secured directly to the FEM support structure. Be certain that the anti-rotation pin on the back of the sensor is engaged in the clearance hole of the bracket or the support structure.
- Install and tighten the screw (2) that secures the sensor. Tighten the screw to 8 N.m (70 in. lbs.).
- Do not reconnect 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 .
