Park Assist Display - Operation

OPERATION

The Park Assist system for this vehicle is only available on vehicles equipped with an Electronic Vehicle Information Center (EVIC). The park assist display is an integrated into the EVIC, which receives battery current and ground through and is completely controlled by the Instrument Cluster (IC) (also known as the Common Instrument Cluster/CIC). The IC will display the park assist icon whenever an object is detected and a signal is received from the park assist module over the Controller Area Network (CAN) data bus. The icon image displayed has as many as 24 different variations depending upon size, distance and location of the object being detected. The microprocessor in the park assist module continually monitors the display status, and will store a Diagnostic Trouble Code (DTC) in memory for any monitored fault detected in the park assist display.

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 or 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.
