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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      A-24 (UP) - A-16 (GND9) UP switch is pressed Below 1 Ω
      A-24 (UP) - A-16 (GND9) UP switch is not pressed 10 kΩ or higher
      A-23 (DOWN) - A-16 (GND9) DOWN switch is pressed Below 1 Ω
      A-23 (DOWN) - A-16 (GND9) DOWN switch is not pressed 10 kΩ or higher
      B-3 (OPN) - A-16 (GND9) OPEN switch is pressed Below 1 Ω
      B-3 (OPN) - A-16 (GND9) OPEN switch is not pressed 10 kΩ or higher
      B-12 (CLS) - A-16 (GND9) CLOSE switch is pressed Below 1 Ω

  4. CHECK HARNESS AND CONNECTOR (SLIDING ROOF DRIVE GEAR - MAP LIGHT)


    1. Disconnect the R17 sliding roof drive gear sub-assembly (sliding roof ECU) connector.

    2. Disconnect the R7 and R12 map light assembly connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      R17-4 (UP) - R7-24 (UP) Always Below 1 Ω
      R17-6 (DWN) - R7-23 (DOWN) Always Below 1 Ω
      R17-7 (OPN) - R12-3 (OPN) Always Below 1 Ω
      R17-5 (CLS) - R12-12 (CLS) Always Below 1 Ω
      R7-16 (GND9) - Body ground Always Below 1 Ω
      R17-12 (E) - Body ground Always Below 1 Ω
      R17-4 (UP) or R7-24 (UP) - Body ground Always 10 kΩ or higher
      R17-6 (DWN) or R7-23 (DOWN) - Body ground Always 10 kΩ or higher
      R17-7 (OPN) or R12-3 (OPN) - Body ground Always 10 kΩ or higher
