  3. READ VALUE USING INTELLIGENT TESTER (REAR MOTOR LH)


    1. Use the Data List to check if the power window regulator motor is functioning properly.

      RL-Door Motor:
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      RL Door P/W Up SW Rear power window LH manual UP switch signal / ON or OFF

      ON: Rear power window LH manual UP switch operated

      OFF: Rear power window LH switch not operated

      		 -
      RL Door P/W Down SW Rear power window LH manual DOWN switch signal / ON or OFF

      ON: Rear power window LH manual DOWN switch operated

      OFF: Rear power window LH switch not operated

      		 -
      OK
      Tester display changes normally when rear power window switch LH is operated.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      O15-25 (SGND) - O18-5 (GND) Always Below 1 Ω
      O15-25 (SGND) or O18-5 (GND) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  5. CHECK HARNESS AND CONNECTOR (REAR DOOR ECU LH - REAR MOTOR LH)


    1. A01GW97E03

      Disconnect the O14 ECU connector.

    2. Disconnect the O19 motor connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      O14-5 (BDRJ) - O19-2 (B) Always Below 1 Ω
      O14-2 (PWE) - O19-1 (E) Always Below 1 Ω
      O14-5 (BDRJ) or O19-2 (B) - Body ground Always 10 kΩ or higher
      O14-2 (PWE) or O19-1 (E) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  6. CHECK HARNESS AND CONNECTOR (REAR SWITCH LH - REAR MOTOR LH)


    1. A01GXH3E05

      Disconnect the O18 switch connector.

    2. Disconnect the O19 motor connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      O18-2 (UP) - O19-10 (UP1) Always Below 1 Ω
      O18-10 (DOWN) - O19-7 (DWN1) Always Below 1 Ω
      O18-2 (UP) or O19-10 (UP1) - Body ground Always 10 kΩ or higher
      O18-10 (DOWN) or O19-7 (DWN1) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  7. INSPECT REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY (for LH)

    A01GXBQE15

    1. Remove the switch.

    2. Measure the resistance of the switch when the switch is operated.

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      O18-2 (UP) - O18-5 (GND) Manual UP operation Below 1 Ω
      O18-10 (DOWN) - O18-5 (GND) Manual DOWN operation Below 1 Ω
