Park Assist System
A park assist system is an optional factory-installed electronic parking aid. In some markets only a rear park assist system is offered, while other markets may have both front and rear park assist systems available. During parking and other similar vehicle maneuvers, this system alerts the vehicle operator to obstacles located in the path immediately in front of or behind the vehicle which, due to the surrounding vehicle structures, might be otherwise difficult to perceive. When an object is detected, the system uses a park assist display unit within the instrument cluster, 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.
- Park Assist Switch (2) - The optional park assist system can be manually disabled or enabled using the U-Connect Touch ™ screen module; located in the instrument panel center stack. The operator can select from one of three options under the settings tab to enable or disable the system, the tone alerts, or the visual alerts.
- Park Assist Module (3) - Vehicles equipped with the park assist system include a park assist module which is concealed within the molded plastic park assist module housing. There are three mounting tabs integral to the module housing that secure the module to the vehicle body. Two connector receptacles containing terminal pins that connect the module to the vehicle electrical system are integral to the one side of the housing. The module is located at the left rear of the vehicle, behind the rear cargo bin, and beneath the liftgate opening sill plate.
- Park Assist Sensors (4) - Vehicles equipped with the rear park assist system have four ultrasonic park assist sensors that are concealed behind the rear bumper fascia. Each sensor is snapped into an individual molded plastic mounting bracket located 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 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 are damaged in any way, that component must be replaced.
