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 to a stamped metal mounting bracket (2). The EPPM and mounting bracket unit is secured by four hex nuts to four weld studs on the floor panel just behind the front seat cross member under the left front seat.
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.
A molded plastic electrical connector (3) with two receptacles containing numerous terminal pins, exits the inboard 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 EPPM and the stamped metal mounting bracket are serviced only as a unit.
