      Disconnect the K2 connector.

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

      Standard voltage
      Tester Connection Condition Specified Condition
      K2-3 (B) - Body ground Ignition switch on (IG) 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT POWER WINDOW SWITCH (REAR LH)


    1. A017D13E06

      Measure the resistance when the switch is operated according to the value(s) in the table below.

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      1 (D) - 2 (SD) UP Below 1 Ω
      3 (B) - 4 (U) Below 1 Ω
      1 (D) - 2 (SD) OFF Below 1 Ω
      4 (U) - 5 (SU) Below 1 Ω
      4 (U) - 5 (SU) DOWN Below 1 Ω
      1 (D) - 3 (B) Below 1 Ω

    NG

    OK

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


    1. A017EAAE05

      Disconnect the K2 and K3 connectors.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      K2-4 (U) - K3-1 (U) Always Below 1 Ω
      K2-1 (D) - K3-2 (D) Always Below 1 Ω
      K2-4 (U) - Body ground Always 10 kΩ or higher
      K2-1 (D) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH)


    1. Check power window regulator motor operation.


      1. Remove the power window regulator motor Click here.

        A017EIGE06

      2. Apply battery voltage to the motor connector according to the table below.

        Note

        Do not apply battery voltage to any terminals except terminals 1 and 2.

        OK
        Measurement Condition Specified Condition

        Battery negative (-) → Terminal 1

        Battery positive (+) → Terminal 2

        		 Motor gear rotates clockwise

        Battery negative (-) → Terminal 2

        Battery positive (+) → Terminal 1

        		 Motor gear rotates counterclockwise

    2. Check PTC operation.

      Note

      The work must be performed with the power window regulator and door glass installed on the vehicle.


      1. Install the power window regulator motor Click here.

      2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 1.

        A017D69E21

        Note

        Match the arrow mark of the probe with the direction of the current flow.

      3. Fully close the door glass by pressing the power window UP switch. Wait for approximately 60 seconds.

      4. Continue to press the power window UP switch and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (Inspection of current shut-off).

        Standard
        4 to 90 seconds

      5. 60 seconds after the previous step, press the power window DOWN switch (rear LH side).

        OK
        The rear LH side window goes down.

    NG

    OK

  5. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - SWITCH (REAR LH))


    1. A017EGFE02

      for LHD:


      1. for Rear LH side:

        Disconnect the M1 and K2 connectors.

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

        Standard resistance
        Tester Connection Condition Specified Condition
        M1-12 (U) - K2-5 (SU) Always Below 1 Ω
        M1-13 (D) - K2-2 (SD) Always Below 1 Ω
        M1-12 (U) - Body ground Always 10 kΩ or higher
        M1-13 (D) - Body ground Always 10 kΩ or higher
    2. A017EGFE09

      for RHD:


      1. for Rear LH side:

        Disconnect the L1 and K2 connectors.

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

        Standard resistance
        Tester Connection Condition Specified Condition
        L1-18 (U) - K2-5 (SU) Always Below 1 Ω
        L1-10 (D) - K2-2 (SD) Always Below 1 Ω
