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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      R6-6 (CB+) - Body ground G - 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 R6 rear television camera assembly connector.

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

      Tech Tips

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

      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 R6-3 (CV+) - R6-2 (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.
