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

      Standard Voltage

      Tester Connection Switch Condition Specified Condition
      N2-3 (B) - Body ground Always 11 to 14 V
      N2-13 (B) - Body ground Ignition switch ON 11 to 14 V

      Standard Resistance

      Tester Connection Condition Specified Condition
      N2-1 (E) - Body ground Always Below 1 Ω

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

    Result: 

    OK 

    See step  5

  5. CHECK HARNESS AND CONNECTOR (DRIVER SIDE MOTOR - BATTERY AND BODY GROUND) 
    1. Disconnect the N12 motor connector.

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

      Standard Voltage

      Tester Connection Condition Specified Condition
      N12-2 (B) - Body ground Always 11 to 14 V

      Standard Resistance

      Tester Connection Condition Specified Condition
      N12-1 (GND) - Body ground Always Below 1 Ω

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

    Result: 

    OK 

    See step  6

  6. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - DRIVER SIDE MOTOR)

    2. Disconnect the N12 motor connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      N2-4 (UP) - N12-10 (UP) Always Below 1 Ω
      N2-5 (DOWN) - N12-7 (DOWN) Always Below 1 Ω
      N2-4 (UP) - Body ground Always 10 kΩ or higher
      N2-5 (DOWN) - Body ground Always 10 kΩ or higher

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

    Result: 

    OK 

    See step  7

  7. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH 
    1. Remove the driver side motor (Refer to REMOVAL [08/2015 - 08/2017] ).

    2. Apply positive (+) battery voltage to 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 to the door.
    3. Apply negative (-) battery voltage to connector terminals 1 (GND) and 7 (DOWN) / 10 (UP).
    4. Check that the motor gear rotates smoothly as follows.

      OK

      Measurement Condition Specified Condition
      Battery positive (+) → 2 (B)
      Battery negative (-): 1 (GND) (3 sec. or more) → 1 (GND) and 10 (UP) (within 1 sec.) → 1 (GND) (within 1 sec.) → 1 (GND) and 10 (UP)      		 Motor gear rotates clockwise
      Battery positive (+) → 2 (B)
      Battery negative (-): 1 (GND) (3 sec. or more) → 1 (GND) and 7 (DOWN) (within 1 sec.) → 1 (GND) (within 1 sec.) → 1 (GND) and 7 (DOWN)      		 Motor gear rotates counterclockwise

    Result: 

    OK 

    REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
