      A43-12 (IG) - Body ground
      		Ignition switch OFF
      		Below 1 V

    3. Measure the resistance of the wire harness side connector.

      Standard Resistance:
      Tester Connection
      		Specified Condition
      A43-1 (GND1) - Body ground
      		Below 1 Ω

  1. w/o Accessory Meter:

    1. Disconnect the P16 telltale light connector.

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

      Standard Voltage:
      Tester Connection
      		Condition
      		Specified Condition
      P16-3 - Body ground
      		Ignition switch ON
      		11 to 14 V
      P16-3 - Body ground
      		Ignition switch OFF
      		Below 1 V

    3. Measure the resistance of the wire harness side connector.

      Standard Resistance:
      Tester Connection
      		Specified Condition
      P16-1 - Body ground
      		Below 1 Ω
