DESCRIPTION

The navigation ECU sub-assembly receives luggage compartment door lock assembly open/close signals from the main body ECU (multiplex network body ECU) via CAN communication. When the luggage compartment door is open, the camera aiming cannot be adjusted correctly because the rear television camera assembly is installed on the luggage compartment 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.

HINT
* Check the parking assist monitor screen display mode settings. (Check if the parking guide lines are set to off.)
* The luggage compartment door lock assembly is connected to the main body ECU (multiplex network body ECU) by the vehicle wire harness.
