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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      V8-4 (CB+) - Body ground B - Body ground Power source

      • Power switch on (IG)

      • Reverse (R) selected

      		 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 V8 rear television camera assembly connector.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      V8-2 (CV+) - V8-1 (CV-) R - W Video signal

      • Power switch on (IG)

      • Reverse (R) selected

      • Camera lens not covered, displaying an image

      Pulse generation

      (See waveform 1)

      • Power switch on (IG)

      • Reverse (R) selected

      • Camera lens covered, blacking out the 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 multi-media module receiver assembly with the connector connected.

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