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 the side impact sensors are NOT interchangeable.
- Position the right or left front impact sensor (1) to the outboard side of the Front End Module (FEM) vertical support (2) between the cooling module and the front lamp unit opening.
- Be certain to engage the locating pin integral to the sensor into the locating hole in the FEM vertical support.
- Install and tighten the screw (3) that secures the sensor to the FEM vertical support. Tighten the screw to the proper specifications. Refer to TORQUE SPECIFICATIONS .
- Connect the FEM wire harness connector (4) to the sensor connector receptacle.
- Install the right or left front lamp unit to the vehicle. Refer to UNIT, FRONT LAMP, 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 SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
