  2. CHECK HARNESS AND CONNECTOR (LUGGAGE CLOSER MOTOR ASSEMBLY - LUGGAGE DOOR CLOSER ASSEMBLY)


    1. Disconnect the L10 luggage closer motor assembly connector.

    2. Disconnect the L12 luggage door closer assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      L10-16 (CSG) - L12-4 (CPSE) Always Below 1 Ω
      L10-17 (CS2) - L12-9 (CPS2) Always Below 1 Ω
      L10-18 (CS1) - L12-2 (CPS1) Always Below 1 Ω
      L10-19 (CSV) - L12-3 (CPS+) Always Below 1 Ω
      L10-16 (CSG) or L12-4 (CPSE) - Body ground Always 10 kΩ or higher
      L10-17 (CS2) or L12-9 (CPS2) - Body ground Always 10 kΩ or higher
      L10-18 (CS1) or L12-2 (CPS1) - Body ground Always 10 kΩ or higher
      L10-19 (CSV) or L12-3 (CPS+) - Body ground Always 10 kΩ or higher
