      Standard Resistance
      Tester Connection Condition Specified Condition
      R12-2 (CV+) - O10-7 (CV+) Always Below 1 Ω
      R12-4 (CB+) - O10-14 (CB+) Always Below 1 Ω
      R12-3 (CGND) - O10-13 (CGND) Always Below 1 Ω
      R12-1 (CV-) - O10-6 (CV-) Always Below 1 Ω
      R12-2 (CV+) - Body ground Always 10 kΩ or higher
      R12-4 (CB+) - Body ground Always 10 kΩ or higher
      R12-3 (CGND) - Body ground Always 10 kΩ or higher
      R12-1 (CV-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT INNER REAR VIEW MIRROR ASSEMBLY

      *d Video Waveform

      Check the waveform of the rear television camera assembly using an oscilloscope.

      Tech Tips

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the inner rear view mirror assembly with the connector connected.

      OK
      Waveform is similar to that shown in the illustration.

      Terminal No. (Symbol) O10-7 (CV+) - O10-2 (E)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition Power switch on (READY), reverse (R) selected

      Tech Tips

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