    1. Disconnect the P3 connector from the rear television camera assembly.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      P3-3 (CGND) - Body ground BR - Body ground Ground Always Below 1 V
      P3-4 (CB+) - P3-3 (CGND) R - BR Power source

      Ignition switch ON

      Shift lever in R

      		 5.5 to 7.0 V

      Tech Tips

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

    3. Reconnect the P3 connector to the rear television camera assembly.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      P3-2 (CV+) - P3-1 (CV-) B - W Display signal

      Ignition switch ON

      Shift lever in R

      Under normal conditions

      Tech Tips


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

      • If the result is not as specified, the camera may have a malfunction.
