Display, Park Assist: Operation

The park assist display provides the vehicle operator with visual feedback by illuminating a vehicle graphic and eight or fewer object detection bar and arc sections in two zones at the rear of the icon indicating the approximate relative location and distance of an object or obstacle from the rear bumper of the vehicle. The fewer bar and arc sections illuminated, the nearer the object. In addition, the nearest bar sections can change from solid illumination to flashing on and off as the object or obstacle becomes nearer.

The Instrument Cluster (IC) (also known as the Common Instrument Cluster/CIC) will display the park assist graphics in the Electronic Vehicle Information Center (EVIC) electronic display unit whenever an object is within the detection area and an electronic request message is received from the Park Assist Module (PAM) (also known as the ParkTronic System/PTS module) over the Controller Area Network (CAN) data bus.

The hard wired circuits between components related to the park assist display may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the park assist display or the electronic controls and communication between modules and other devices that provide some features of the park assist system. The most reliable, efficient and accurate means to diagnose the park assist display or the electronic controls and communication related to park assist display operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
