Module, Park Assist (PAM): Description
The Park Assist Module (PAM) (1) is secured with two nuts to weld studs through two mounting tabs integral to the module housing on the left quarter inner panel just behind the left rear wheel house. The module is concealed behind the quarter inner trim within the cargo area of the vehicle. Concealed within the molded plastic PAM housing is a microcontroller and the other electronic circuitry of the module. The module housing is sealed to enclose and protect the internal electronic circuitry.
There are three unique versions of the PAM used that are similar in appearance, but are not interchangeable. The PAM version depends upon the version of the park assist system in the vehicle. The Rear Park Assist (RPA) uses a 4 channel PAM, the Front and Rear Park Assist (FRPA) system uses a 10 channel PAM, and the Parallel and Perpendicular Park Assist (PPPA) uses a 12 channel PAM.
Two or three connector receptacles containing terminal pins are integral to the downward-facing side of the housing. The module is connected to the vehicle electrical system through dedicated take outs and connectors of the body wire harness. The number of connector receptacles and body harness take outs also depends upon which of the three available versions of the park assist system is installed in the vehicle.
The PAM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced with a new unit. The PAM software is flash programmable.
