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

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      Y14-4 (CB+) - Body ground B - Body ground Power source

      Engine switch on (IG)

      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 Y14 rear television camera assembly connector.

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