Park Assist System Chime/Buzzer - Description

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 displays a textual message within the Electronic Vehicle Information Center (EVIC) display unit to provide the vehicle operator with visual and 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:

- Electronic Vehicle Information Center (1) - In vehicles equipped with the optional park assist system, the optional EVIC in the instrument cluster displays textual warnings and error messages, and emits audible warnings related to the current operating status of the park assist system. The display also provides an interface that allows the vehicle operator to manually disable or enable the system using the customer programmable features option.
- Park Assist Module (2) - Vehicles equipped with the park assist system include a park assist module which is secured to a mounting bracket by two fasteners and is concealed above the headliner.
- Park Assist Sensors (3) - Vehicles equipped with the park assist system have four ultrasonic park assist sensors that are concealed behind the rear bumper. Each sensor is snapped into an individual molded plastic mounting bracket located at horizontal intervals along the back side of the rear bumper.

Hardwired circuitry connects the various park assist system components to each other through the electrical system of the vehicle. These hardwired 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-out 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.
