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

        D DOOR MOTOR: 

        DATA LIST - D DOOR MOTOR

        Tester Display Measurement Item/Range Normal Condition
        D P/W UP SW Driver side power window MANUAL UP switch signal / ON or OFF ON Driver side power window manual UP switch operated
        OFF Driver side power window switch not operated
        D P/W DOWN SW Driver side power window MANUAL DOWN switch signal / ON or OFF ON Driver side power window manual DOWN switch operated
        OFF Driver side power window switch not operated
      2. Techstream

      D-Door Motor: 

      DATA LIST - D DOOR MOTOR

      Tester Display Measurement Item/Range Normal Condition
      D Door P/W Up SW Driver side power window MANUAL UP switch signal / ON or OFF ON Driver side power window manual UP switch operated
      OFF Driver side power window switch not operated
      D Door P/W Down SW Driver side power window MANUAL DOWN switch signal / ON or OFF ON Driver side power window manual DOWN switch operated
      OFF Driver side power window switch not operated

    OK: Tester display changes normally when master switch is operated. 

    NG:  Go to step  4

    OK: REPLACE FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH  (see REMOVAL )

  4. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - DRIVER SIDE DOOR ECU) 
    1. Disconnect the P10 ECU connector.
    2. Disconnect the N13 switch connector
    3. Measure the resistance according to the value (s) in the table below.

    Standard resistance 

    STANDARD RESISTANCE SPECIFICATION

    Tester Connection Condition Specified Condition
    P10-27 (SGND) - N13-12 (GND) Always Below 1 Ω
    P10-26 (CPBJ) - N13-11 (B) Always Below 1 Ω
    P10-27 (SGND) or N13-12 (GND) - Body ground Always 10 kΩ or higher
    P10-26 (CPBJ) or N13-11 (B) - Body ground Always 10 kΩ or higher

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK: Go to Next Step 

  5. CHECK HARNESS AND CONNECTOR (DRIVER SIDE DOOR ECU - DRIVER SIDE MOTOR) 
    1. Disconnect the N10 ECU connector.
    2. Disconnect the N11 motor connector.
    3. Measure the resistance according to the value (s) in the table below.

    Standard resistance 

    STANDARD RESISTANCE SPECIFICATION

    N10-5 (BDRJ) - N11-2 (B) Always Below 1 Ω
    N10-2 (PWE) - N11-1 (E) Always Below 1 Ω
    N10-5 (BDRJ) or N11-2 (B) - Body ground Always 10 kΩ or higher
    N10-2 (PWE) or N11-1 (E) - Body ground Always 10 kΩ or higher

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK: Go to Next Step 

  6. CHECK HARNESS AND CONNECTOR (DRIVER SIDE MOTOR - MASTER SWITCH) 
    1. Disconnect the N13 switch connector.
    2. Disconnect the N11 motor connector.
    3. Measure the resistance according to the value (s) in the table below.

    Standard resistance 

    STANDARD RESISTANCE SPECIFICATION

    N13-20 (UP) - N11-10 (UP1) Always Below 1 Ω

    OK: Go to Next Step 

  7. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY 
    1. Remove the motor (see REMOVAL ).
    2. Apply positive (+) battery voltage to the connector terminal 2 (B).
      NOTE:
      • Do not apply positive (+) battery voltage to any terminals, except terminal 2 (B), to avoid damaging the pulse sensor inside the motor.
      • Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly onto the door.
    3. Apply negative (-) battery voltage to the connector terminals 1 (E) and 7 (DWN1)/ 10 (UP1).
    4. Check that the motor gear rotates smoothly as follows.
