PARKING ASSIST MONITOR SYSTEM(w/o Side Monitor System) Guide Lines and Buttons are not Displayed for All Display Modes

DTC Code DTC Name
Guide Lines and Buttons are not Displayed for All Display Modes

DESCRIPTION

The multi-media module receiver assembly receives back door open/close signals from the main body ECU (multiplex network body ECU) via CAN communication. When the back door is open, the camera aiming cannot be adjusted correctly because the rear television camera assembly is installed on the back door. Therefore, when performing back camera position setting while the back door is open, a back door open warning message will be displayed on the screen and back camera position setting will be canceled.

Tip:

Check the parking assist monitor screen display mode settings. (Check if the parking guide lines are set to off.)
