Electronic Pedestrian Protection Impact Sensor - Installation

ELECTRONIC PEDESTRIAN PROTECTION

WARNING: To avoid serious or fatal injury on vehicles equipped with the Electronic Pedestrian Protection (EPP) system, disable the system before attempting any EPP system component diagnosis or service. With the ignition switch in the OFF position, 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 EPP system. Failure to take the proper precautions could result in accidental active hood hinge actuator deployment.

WARNING: To avoid serious or fatal injury, never strike or drop the Electronic Pedestrian Protection (EPP) system impact sensor, as it can damage the impact sensor or affect its calibration. The EPP impact sensor enables the system to deploy the EPP system active hood hinge actuators. 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 EPP active hood hinge actuator deployment.

NOTE: The following procedure is for replacement of an ineffective or damaged Electronic Pedestrian Protection (EPP) system impact sensor. Whether the EPP system has been deployed or the vehicle has had a front end collision without EPP system deployment, review the recommended procedures for Service After A Pedestrian Protection Deployment before removing the unit from the vehicle.

1. Carefully inspect the U-nut for the center or outboard Electronic Pedestrian Protection (EPP) impact sensor to be certain it is good condition and is properly installed in the molded bracket integral to the back of the front fascia (1).
2. Carefully position the EPP impact sensor (2) to the molded bracket. Be certain that the latches of the anti-rotation pin on the back of the sensor are engaged in the clearance hole of the bracket.
3. Install and tighten the screw (4) that secures the sensor to the U-nut in the molded bracket. Tighten the screw to 8 Nm (70 in. lbs.).
4. Reconnect the front fascia wire harness connector (3) to the EPP impact sensor connector receptacle.
5. Reinstall the front fascia onto the vehicle. Front Bumper Fascia - Installation.
6. Do not reconnect the battery negative cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any EPP system component. Service and Repair.
