PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (BODY ECU - MAP LIGHT ASSEMBLY AND BODY GROUND)


    1. Disconnect the G27 body ECU connector.

    2. Disconnect the Q3 map light assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      G27-10 (SSW1) - Q3-7 (IND2) Always Below 1 Ω
      Q3-3 (GND) - Body ground Always Below 1 Ω
      G27-10 (SSW1) - Body ground Always 10 kΩ or higher
      Q3-7 (IND2) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
