INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY

Remove the motor.
Apply positive (+) battery voltage to the connector terminal 2.
NOTE:
- Do not apply positive (+) battery voltage to any terminals, except terminal 2, 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.
Apply negative (-) battery voltage to the connector terminals 1 and 7/10.

Check that the motor gear rotates smoothly as follows.

MEASUREMENT CONDITION CHART

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

NG: REPLACE FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH (for Driver Side) (See REMOVAL )

OK: REPLACE MASTER SWITCH ASSEMBLY (See REMOVAL )
