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, airbag, Occupant Classification System (OCS), 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 follow these instructions may 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 (2) onto the back of the bracket near the right or left end of the front frame cross member (1).
- Be certain to engage the locating pin integral to the sensor into the locating hole in the cross member bracket.
- Install and tighten the screw (4) that secures the sensor to the back of the cross member bracket. Tighten the screw to 7 N.m (62 in. lbs.).
- Connect the headlamp and dash wire harness connector (3) to the sensor connector receptacle.
- Install the front fascia onto the vehicle. Refer to FASCIA, FRONT, INSTALLATION .
- Do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to STANDARD PROCEDURE .
