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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      2 (UP) - 5 (GND) Manual up operation Below 1 Ω
      10 (DOWN) - 5 (GND) Manual down operation Below 1 Ω
      4 (AUTO) - 5 (GND) Auto up/down operation Below 1 Ω
      2 (UP) - 5 (GND) Not operated 10 kΩ or higher
      10 (DOWN) - 5 (GND) Not operated 10 kΩ or higher
      4 (AUTO) - 5 (GND) Not operated 10 kΩ or higher

  3. CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY LH - REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH)


    1. Disconnect the R14 rear power window regulator switch assembly LH connector.

    2. Disconnect the R9 rear power window regulator motor assembly LH connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      R14-2 (UP) - R9-10 (UP1) Always Below 1 Ω
      R14-10 (DOWN) - R9-7 (DWN1) Always Below 1 Ω
      R14-2 (UP) - Body ground Always 10 kΩ or higher
      R14-10 (DOWN) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH - BATTERY AND BODY GROUND)
