      1. Standard: 
      IDENTIFYING TERMINAL SPECIFICATION

      Symbols (Terminal No.) Wiring Color Condition Specified condition
      GND <=> Body ground (M2-14 <=> Body ground) W-B <=> Body ground Constant Continuity
      GND <=> B (M2-14 <=> M2-1) W-B <=> W-R Constant 10-14V
      ACC<=>GND (M2-2 <=> M2-14) GR <=> W-B Ignition switch OFF --> ACC 0V --> 10-14V

      HINT:

      If the value is not as specified, a malfunction exists in the wire harness side.

    3. Connect the M2 connector, and check the voltage between each terminal of the connector.
