Diagnostic Fault Information






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 Park Assist 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 received input from several modules including the park assist module to provide additional features. Refer to Object Detection Description and Operation (with Active Safety System - UGN) Object Detection Description and Operation (with Active Safety System - UGN)Object Detection Description and Operation (with rear vision camera - UVC) Object Detection Description and Operation (with rear vision camera - UVC)Object Detection Description and Operation (with front and rear park assist - UD5) Object Detection Description and Operation (With Front and Rear Park Assist - UD5)Object Detection Description and Operation (with rear park assist - UD7) Object Detection Description and Operation (With Rear Park Assist - UD7)Object Detection Description and Operation (with side blind zone alert - UFT) Object Detection Description and Operation (with side blind zone alert - UFT)Object Detection Description and Operation (with rear cross traffic alert - UFG) Object Detection Description and Operation (With Rear Cross Traffic Alert - UFG)Object Detection Description and Operation (with lane departure warning - UFL) Object Detection Description and Operation (With Lane Departure Warning - UFL)Object Detection Description and Operation (with forward collision alert - UEU) Object Detection Description and Operation (With Forward Collision Alert - UEU)Object Detection Description and Operation (with Haptic Signal Motor Seat) Object Detection Description and Operation (with Haptic Signal Motor Seat) for additional information on UGN. The park assist alerts and DTCs originate from the Park Assist 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.
