REAR VIEW MONITOR SYSTEM (w/o Navigation System) TERMINALS OF ECU


  1. TELEVISION CAMERA ASSEMBLY

    A017COVE19

    1. Disconnect the T16 connector from the 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
      T16-3 (CGND) - Body ground W - Body ground Ground Always Below 1 V
      T16-4 (CB+) - T16-3 (CGND) B - W Power source

      Ignition switch ON

      Shift lever in R

      		 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 T16 connector to the television camera assembly.

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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      T16-2 (CV+) - T16-1 (CV-) R - L Display signal

      Ignition switch ON

      Shift lever in R

      Camera lens not covered, displaying an image

      Pulse generation

      (See waveform 1)

      Ignition switch ON

      Shift lever in R

      Camera lens covered, blacking out screen

      Pulse generation

      (See waveform 2)

      Tech Tips

      A waterproof connector is used for the television camera assembly. Therefore, inspect the waveform at the navigation receiver assembly with the connector connected.

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