    CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY)


    1. Disconnect the H97 multi-media module receiver assembly connector.

    2. Disconnect the U6 rear television camera assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H97-39 (CA+) - U6-6 (CB+) Always Below 1 Ω
      H97-18 (V+) - U6-3 (CV+) Always Below 1 Ω
      H97-19 (V-) - U6-2 (CV-) Always Below 1 Ω
      H97-40 (CGND) - U6-5 (CGND) Always Below 1 Ω
      H97-39 (CA+) - Body ground Always 10 kΩ or higher
      H97-18 (V+) - Body ground Always 10 kΩ or higher
      H97-19 (V-) - Body ground Always 10 kΩ or higher
      H97-40 (CGND) - Body ground Always 10 kΩ or higher

      A0005HZE11

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

      Tip:

      A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the multi-media module receiver assembly with the connector connected.

      OK
      Waveform is as shown in the illustration.
      Item Content
      Terminal No. (Symbol) H97-18 (V+) - H97-12 (GND1)
      Tool Setting 200 mV/DIV., 50 μsec./DIV.
      Condition Power switch on (IG), shift lever in R
      Tip:

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