PARKING ASSIST MONITOR SYSTEM Guide Lines and Buttons are not Displayed for All Display Modes

DESCRIPTION

The navigation ECU sub-assembly receives back door lock assembly open/close signals from the main 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 adjusting the camera aiming calibration while the back door is open, a back door open warning message will be displayed on the screen and camera aiming adjustment will be canceled.

Tech Tips


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

  • The back door lock assembly is connected to the main body ECU by the vehicle wire harness.
