    Always
    10 kΩ or higher
    N2-5 (DOWN) - Body ground
    Always
    10 kΩ or higher


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


7.INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH


    B231475E01
  1. Remove the driver side motor (Click here).

  1. Apply positive (+) battery voltage to connector terminal 2 (B).

    NOTICE:
    1. Do not apply positive (+) battery voltage to any terminals except terminal 2 (B) to avoid damaging the pulse sensor inside the motor.
    2. Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly to the door.
  1. Apply negative (-) battery voltage to connector terminals 1 (GND) and 7 (DOWN) / 10 (UP).

  1. 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
