  2. *2: w/ TOYOTA Parking Assist-Sensor System
  3. *3: w/ Blind Spot Monitor System

  1. This system has a rear television camera assembly mounted on the back door to display an image of the area behind the vehicle on the multi-display assembly . The multi-display assembly 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.

  2. This system consists of the following components:

    1. Rear television camera assembly

    2. Multi-media module receiver assembly

    3. Multi-display assembly

    4. Spiral with sensor cable sub-assembly

    5. Main body ECU (multiplex network body ECU)

    6. Combination meter assembly

    7. Steering control ECU*1

    8. Clearance warning ECU assembly*2

    9. Park/neutral position switch assembly

    10. Blind spot monitor sensor LH*3

  3. This system is equipped with a self-diagnosis system, which is operated on a designated window that appears on the multi-display assembly.


FUNCTION OF COMPONENTS

  1. The multi-media module receiver assembly controls the system by using information from the following components.

    Item
    		Function
    Rear Television Camera Assembly
    1. Mounted on the back door to transmit an image of the area behind the vehicle to the multi-media module receiver assembly.
    2. Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and wide-angle lens.
    Multi-media Module Receiver Assembly
    1. Receives video signals, which contain an image of the area behind the vehicle taken with the rear television camera assembly.
    2. Performs overall control of the system by receiving signals from the sensors.
    3. Creates images and displays adjustment screens performed in DIAGNOSTIC mode.
    4. Stops displaying the guide lines and buttons and displays "Check surrounding for safety" when an open signal is received for the back door.
    5. Displays "Back door is open. Do not use the rear view monitor when the back door is not completely closed." on the back camera position setting screen when an open signal is received for the back door.
    6. Performs control of the system by receiving the reverse signal from the park/neutral position switch assembly.
    Multi-display Assembly
    		Receives the video signals containing a composite of an image of the area behind the vehicle and parking assist guide line signals from the multi-media module receiver assembly, and displays them on the multi-display.
    Spiral with Sensor Cable Sub-assembly
    		Detects the angle of the steering wheel and transmits the resulting signals to the multi-media module receiver assembly via CAN communication.
    Combination Meter Assembly
    		Transmits a vehicle speed signal to the multi-media module receiver assembly via CAN communication.
    Main Body ECU (Multiplex Network Body ECU)
    1. Transmits a back door courtesy switch signal to the multi-media module receiver assembly via CAN communication.
    2. Transmits a vehicle information signal to the rear television camera assembly via CAN communication.
    Steering Control ECU*1
    		Transmits a VGRS relative angle signal to the multi-media module receiver assembly via CAN communication.
    Clearance Warning ECU Assembly*2
    		Transmits a sonar information signal to the multi-media module receiver assembly via CAN communication.
    Blind Spot Monitor Sensor LH*3
    		Transmits a RCTA information signal to the multi-media module receiver assembly via CAN communication.
    Park/Neutral Position Switch Assembly
    		Transmits a reverse signal to the multi-media module receiver assembly.

OPERATION EXPLANATION

  1. The multi-media module receiver assembly receives the reverse signal when the engine switch is on (IG) and the shift lever is moved to R. After receiving the reverse signal, the multi-display switches to the parking assist monitor system.
