REAR VIEW MONITOR SYSTEM TERMINALS OF ECU


  1. REAR TELEVISION CAMERA ASSEMBLY


    1. Disconnect the T6 connector from the rear television camera assembly.

      A01HTBHE01

    2. Measure the voltage of each terminal of the wire harness side connector.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      T6-6 (CB+) - Body ground B - Body ground Power source

      Power switch on (IG)

      Shift lever in R*1

      		 5.5 to 7.05 V
      Within 60 seconds of turning the power switch on (ACC)*2 5.5 to 7.05 V

      • *1: for Navigation Receiver Type

      • *2: for Radio and Display Type

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

    3. Reconnect the T6 connector to the rear television camera assembly.

    4. Check for pulses between each terminal of the connector.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      T6-3 (CV+) - T6-2 (CV-) W - R Video signal

      Power switch on (IG)

      Shift lever in R

      Camera lens not covered, displaying an image

      Pulse generation

      (See waveform 1)

      Power switch on (IG)

      Shift lever in R

      Camera lens covered, blacking out screen

      Pulse generation

      (See waveform 2)

      Tech Tips

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

      If the result is not as specified, the camera may have a malfunction.

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

        Item Content
        Terminal No. (Symbol) T6-3 (CV+) - T6-2 (CV-)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Power switch on (IG), shift lever in R

        Tech Tips

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

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

        Item Content
        Terminal No. (Symbol) T6-3 (CV+) - T6-2 (CV-)
        Tool Setting 200 mV/DIV., 50 μsec./DIV.
        Condition Power switch on (IG), shift lever in R

        Tech Tips

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