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, Park Assist (PAM): Description
The Park Assist Module (PAM) (1) (also known as the ParkTronic System/PTS module) is located on the inboard side of the right lower D-pillar behind the interior quarter trim panel. The PAM is connected to the vehicle electrical system through dedicated take outs of the body wire harness. Concealed within the molded plastic PAM housing (1) is a microcontroller and the other electronic circuitry of the module. The PAM housing is sealed to enclose and protect the internal electronic circuitry. The module software is flash programmable.
There are three mounting tabs integral to the PAM housing that secure the module to the vehicle body. Two mounting tabs (5) secure the PAM in place by engaging two slots in the vehicle body. The third tab (2) is secured by a push-in type plastic retainer. Three connector receptacles integral to the PAM housing contain terminal pins that connect the module to the vehicle electrical system. Two of the receptacles (4) are utilized in vehicles equipped with only the Rear Park Assist (RPA) system, while the third receptacle (3) is utilized only on vehicles equipped with the Front and Rear Park Assist (FRPA) system.
The PAM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced with a new unit.
