REAR VIEW MONITOR SYSTEM TERMINALS OF ECU


  1. REAR TELEVISION CAMERA ASSEMBLY


    1. Disconnect the V14 rear television camera assembly connector.

      A005CQEE02

    2. Measure the voltage on the wire harness side connector according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      V14-6 (CB+) - Body ground W - Body ground Power source Power switch on (ACC) 5.5 to 7.05 V

      If the result is not as specified, there may be a malfunction on the wire harness side.

    3. Reconnect the V14 rear television camera assembly connector.

    4. Measure the voltage and check for pulses at each terminal of the connector.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      V14-3 (CV+) - V14-2 (CV-) R - B Video signal

      Power switch on (IG)

      Reverse (R) selected

      Camera lens not covered, displaying an image

      Pulse generation

      (Refer to waveform 1)

      Power switch on (IG)

      Reverse (R) selected

      Camera lens covered, blacking out screen

      Pulse generation

      (Refer to waveform 2)
      V14-5 (CGND) - Body ground W-B - Body ground Shield ground Always Below 1 V

      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the navigation receiver assembly*1 or radio and display receiver assembly*2 with the connector connected.


      • *1: for Navigation Receiver Type

      • *2: for Radio and Display Type

      If the result is not as specified, the rear television camera assembly may be malfunctioning.

      1. Waveform 1 (camera lens is not covered, displaying an image)

        Item Content
        Measurement terminal V14-3 (CV+) - V14-2 (CV-)
        Measurement setting 200 mV/DIV., 50 μs./DIV.
        Condition Power switch on (IG), reverse (R) selected

        Tech Tips


        • The video waveform changes according to the image sent by the rear television camera assembly.

        • The video waveform is constantly output when the power switch is on (ACC).

      2. Waveform 2 (camera lens is covered, blacking out the screen)

        Item Content
        Measurement terminal V14-3 (CV+) - V14-2 (CV-)
