Park Assist System: Notes

A park assist system (also known as the ParkTronic System/PTS) is an optional factory-installed electronic parking aid. There are also two distinct versions of the park assist system. The two versions can be readily identified by noting the sensor location in the rear or front and rear bumpers. Additional details of each of these versions and their components can be found elsewhere in this service information.

• Rear Park Assist  - The Rear Park Assist (RPA) alerts the vehicle operator to obstacles located in the path immediately behind the vehicle. This system has four radar sensors, all installed in the rear bumper.
• Front and Rear Park Assist  - The Front and Rear Park Assist (FRPA) alerts the vehicle operator to obstacles located in the path immediately in front of the vehicle as well as those behind. This system has ten radar sensors, four installed in the rear bumper and six installed in the front bumper.

Hard wired circuitry connects the RPA or FRPA components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the RPA or FRPA components through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin out and location views for the various wire harness connectors, splices and grounds.

The RPA and FRPA system components cannot be adjusted or repaired. If any of these components is damaged or ineffective, that component must be replaced.
