Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module, Electronic Pedestrian Protection: Description: Description
The Electronic Pedestrian Protection Module (EPPM) (1) is found only in vehicles equipped with the Electronic Pedestrian Protection (EPP) system (also known as the PedPro or the Active Hood System), which is available only in vehicles manufactured for certain export markets. The EPPM is secured by three hex nuts to three studs on a stamped metal mounting bracket welded to the driver side of the instrument panel cross-car support beam, outboard of the steering column.
Concealed within a hollow in the center of the die cast aluminum EPPM housing is the electronic circuitry of the module which includes a microcontroller and an energy storage capacitor. A stamped metal cover plate is secured to the bottom of the EPPM housing with screws to enclose and protect the internal electronic circuitry and components.
The EPPM housing has three integral mounting tabs (2) and an integral locating pin. A molded plastic electrical connector (3) with two receptacles containing numerous terminal pins, exits the downward facing side of the EPPM housing. These terminal pins connect the EPPM to the vehicle electrical system through two dedicated take outs and connectors from the body wire harness.
The EPPM cannot be repaired or adjusted and, if damaged or ineffective, it must be replaced. The stamped metal mounting bracket is serviced only as a unit with the instrument panel cross-car support structure.
