Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Park Assist System
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
If a SERVICE PARK ASSIST SYSTEM graphic and textual message appears in the Electronic Vehicle Information Center (EVIC) display of the Instrument Panel Cluster (IPC), be certain to confirm the following:
- Be certain that both the face and the back of the bumper fascia is free of dirt and debris to keep the system operating properly.
- Be certain that the parking brake is not applied.
- The presence of operating heavy construction equipment, large trucks and other sources of vibration in the vicinity of the vehicle could also impact the performance of the system.
If a PARK ASSIST DISABLED textual message appears in the EVIC display, the system may either have been manually turned OFF or have a hard fault. If the Park Assist OFF switch is not illuminated, further investigation may be required.
The hardwired circuits between components related to the park assist system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to WIRE SPLICING , CONNECTOR TERMINAL REMOVAL and CONNECTOR TERMINAL INSTALLATION .
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the park assist system 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 system or the electronic controls and communication related to park assist system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
