Park Assist System
A park assist system is an optional factory-installed electronic parking aid. During parking and other similar vehicle maneuvers this system alerts the vehicle operator to obstacles located in the path immediately behind the vehicle which, due to the surrounding rear vehicle structure, might be otherwise difficult to perceive. When an object is detected, the system provides the vehicle operator with audible indications of the presence, and proximity of such objects.
The park assist system includes the following major components, which are described in further detail elsewhere in this service information:
- Instrument Cluster - In vehicles equipped with the optional park assist system, the Instrument Cluster (IC) (1) (also known as the Instrument Panel Cluster/IPC) emits audible warnings related to the current operating status of the park assist system.
- Park Assist Module - Vehicles equipped with the park assist system include a Park Assist Module (PAM) (2) (also known as the ParkTronic System/PTS module), which is secured through integral mounting tabs and a screw to the inner C-pillar panel above the right rear tail lamp assembly where it is concealed beneath the quarter panel inside trim.
- Park Assist Sensors - Vehicles equipped with the park assist system have four ultrasonic park assist sensors (3) that are concealed behind the rear bumper fascia. Each sensor is snapped into an individual molded plastic mounting bracket secured at horizontal intervals along the back side of the rear bumper fascia.
Hard wired circuitry connects the various park assist system components to each other through 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, and to the vehicle electrical system 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 outs and location views for the various wire harness connectors, splices and grounds.
The park assist system components cannot be adjusted or repaired. If any of the park assist system components is damaged or ineffective, that component must be replaced.
