      MASTER SWITCH (POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY)

      Tester Display Test Part Control Range Diagnostic Note
      Driver Side Power Window Driver door power window OFF / UP / DOWN -

      OK

      Driver door power window operates normally.

      WARNING:

      Be careful to avoid injuries as this test causes vehicle parts to move. During the Active Test, the jam protection function will not operate.

    NG → See step   2 

    OK → See step   6 

  2. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - BODY GROUND AND BATTERY) 
    1. Disconnect the power window regulator master switch assembly connector.

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      M17-20 (GND) - Body ground Always Below 1 Ω

      Standard Voltage

      Tester Connection Condition Specified Condition
      M17-8 (B) - M17-20 (GND) Always 11 to 14 V
      M17-9 (IGB) - M17-20 (GND) Engine switch on (IG) 11 to 14 V
      M17-9 (IGB) - M17-20 (GND) Engine switch off Below 1 V
      M17-10 (B) - M17-20 (GND) Always 11 to 14 V

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  3. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side) 
    1. Remove the power window regulator motor assembly (for driver side). Refer to REMOVAL .

      *1 Component without harness connected
      (Power Window Regulator Motor Assembly (for Driver Side))
      *2 Clockwise
      *3 Counterclockwise
    2. Check power window regulator motor operation:
      1. Apply battery voltage to connector terminals 1 and 2.
        NOTE:

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

      2. Check that the motor gear rotates smoothly as follows.

        OK

        Measurement Condition Specified Condition
        Battery positive (+) → 1 (D)
        Battery negative (-) → 2 (U)        		 Motor gear rotates counterclockwise
        Battery positive (+) → 2 (U)
        Battery negative (-) → 1 (D)        		 Motor gear rotates clockwise
    3. Check PTC operation:
      NOTE:

      This check must be performed with the power window regulator and door glass installed on the vehicle.

      1. Install the power window regulator motor assembly (for driver side). Refer to INSTALLATION .
      2. Reconnect the power window regulator master switch connector.
      3. Initialize the power window regulator master switch assembly. Refer to INITIALIZATION .
      4. Connect an electrical tester DC 400 A probe to the wire harness of terminal 2.

        (Power Window Regulator Motor Assembly (for Driver Side))
        NOTE:

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

      5. Fully close the door glass by pulling up the power window regulator master switch assembly. Wait for approximately 60 seconds.
      6. Continue to pull up the power window regulator master switch assembly and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (current shut-off inspection).

        Standard

        4 to 90 seconds

      7. Wait for 60 seconds after the previous step, and then press the power window regulator master switch assembly.

        OK

        The driver door window goes down.

    NG → See step   5 

    OK: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - REGULATOR MOTOR (for Driver Side)) 
    1. Disconnect the power window regulator master switch connector.
    2. Disconnect the power window regulator motor assembly (for driver side) connector.

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      M17-1 (UP) - M16-2 (U) Always Below 1 Ω
      M17-11 (DN) - M16-1 (D) Always Below 1 Ω
      M17-1 (UP) - Body ground Always 10 kΩ or higher
      M17-11 (DN) - Body ground Always 10 kΩ or higher
      M16-2 (U) - Body ground Always 10 kΩ or higher
      M16-1 (D) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   6 

  5. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side). Refer to  REMOVAL
