GENERAL
This system has a television camera assembly mounted on the back door to display an image of the area behind the vehicle on the display. The display panel also shows a composite view consisting of the area behind the vehicle and parking guide lines to assist the driver in parking the vehicle by monitoring the area behind the vehicle.
This system consists of the following components:
Television camera assembly
Radio and display receiver assembly
Spiral with sensor cable sub-assembly
Main body ECU (multiplex network body ECU)
Back door lock assembly
This system is equipped with a self-diagnosis system, which is operated from a designated window that appears on the display panel, just as in the navigation system.
FUNCTION OF COMPONENTS
The television camera assembly controls the system by using information from the following components.

Function
Television Camera Assembly
Mounted on the back door to transmit an image of the area behind the vehicle to the radio and display receiver assembly.
Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and a wide-angle lens.
Performs overall control of the system by receiving signals from the sensors.
Creates images and displays adjustment screens performed on the diagnosis screen.
Stops displaying the guide lines when an open signal is received for the back door.
Displays "Back door is open" on the back camera position setting screen when an open signal is received for the back door.
Radio and display receiver assembly
Receives video signals, which contain an image of the area behind the vehicle taken with the television camera assembly.
Spiral with Sensor Cable Sub-assembly
Detects the angle of the steering wheel and sends the resulting signals to the television camera assembly through CAN communication.
Main Body ECU (Multiplex Network Body ECU)
Transmits a back door courtesy switch signal to the rear television camera assembly through CAN communication.
Back Door Lock Assembly
Transmits a back door courtesy switch signal to the main body ECU (multiplex network body ECU) through CAN communication.
OPERATION EXPLANATION
The television camera assembly sends the display signal to the radio and display receiver assembly. The radio and display receiver assembly receives the reverse signal via a CAN communication line when the power switch is on (IG) and the shift lever is moved to R. After receiving the reverse signal, the radio and display receiver assembly switches to the parking assist monitor system.
DIAGNOSTIC FUNCTION OUTLINE
