    1. Disconnect the main body ECU connectors.
    2. Measure the voltages of the wire harness side connectors.

      Standard voltage: 

      VOLTAGE SPECIFICATION

      Symbols (Terminal No.) Wiring Color Terminal Description Condition Specified Condition
      GND1 (1H-2) - Body ground W-B - Body ground Ground Always Below 1V
      BECU (1B-4) - Body ground W-R - Body ground Power source circuit (From battery) Always 11 to 14 V
      BDR1 (1E-9) - Body ground B-Y - Body ground Power source circuit (From battery) Always 11 to 14 V
      GND2 (1H-2) - Body ground) W-B - Body ground Ground Always Below 1V

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

    3. Reconnect the main body ECU connectors.
    4. Measure the voltage of the wire harness side connectors.
