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.
Circuit/System Description
The parking assist can be enabled/disabled by pressing the parking assist switch. If the parking assist is enabled, engaging the reverse gear activates the parking assist feature. By subsequently pressing the parking assist switch the parking assist can be disabled.
The indicator in the parking assist switch shows the status of the parking assist. If the lamp is ON, parking assist is enabled.
For vehicles without UGN, the indicator and switch are connected to the parking assist control module and the system operates as a stand-alone feature.
With UGN, the indicator and switch are connected to the active safety control module. The active safety control module receives input from several modules including the parking assist control module to provide additional features. Refer to Active Safety System Description and Operation for additional information on UGN. The park assist alerts and DTCs originate from the parking assist control module with the exception of the indicator DTCs which are set by the active safety control module. There are no switch DTCs for vehicles with the active safety control module.
