    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
      T6-6 (CB+) - Body ground L*1, B*2 - Body ground Power source Ignition switch ACC 5.5 to 7.05 V

      • *1: for TMC, TMMR Made

      • *2: for TMMK Made

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

    3. Reconnect the T6 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
      T6-3 (CV+) - T6-2 (CV-) W - R Video signal

      Ignition switch ON

      Shift lever in R

      Camera lens not covered, displaying an image

      Pulse generation

      (Refer to waveform 1)

      Ignition switch ON

      Shift lever in R

      Camera lens covered, blacking out screen

      Pulse generation

      (Refer to waveform 2)
      T6-5 (CGND) - Body ground LG*1, BR*2 - Body ground Shield ground Always Below 1 V

      • *1: for TMC, TMMR Made

      • *2: for TMMK Made

      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 System (for Navigation Receiver Type)

      • *2: for Audio and Visual System (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 T6-3 (CV+) - T6-2 (CV-)
        Measurement setting 200 mV/DIV., 50 μs./DIV.
        Condition Ignition switch ON, shift lever in R

        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 ignition switch is turned to ACC.

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

        Item Content
        Measurement terminal T6-3 (CV+) - T6-2 (CV-)
        Measurement setting 200 mV/DIV., 50 μs./DIV.
        Condition Ignition switch ON, shift lever in R

        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 ignition switch is turned to ACC.
