Power Window Control System: Inspection
- INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER SIDE)
- Check operation of the regulator motor.NOTE: Do not apply battery voltage to any terminal except 1 and 2.
- Apply battery voltage to the motor terminals.
- Check that the motor rotates smoothly.
Ok:
MEASUREMENT CONDITION SPECIFICATIONSMeasurement Condition Specified Condition Battery positive (+) -> Terminal 1 (D) Motor gear rotates clockwise Battery negative (-) -> Terminal 2 (U) Motor gear rotates clockwise Battery positive (+) -> Terminal 2 (U) Motor gear rotates counterclockwise Battery negative (-) -> Terminal 1 (D) Motor gear rotates counterclockwise Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
If the result is not as specified, replace the motor assy.
- Check operation of the PTC inside the regulator motor.NOTE: Work must be performed with the power window regulator and door glass installed to the vehicle.
- Set an electrical tester DC 400 A probe to the wire harness of terminal 2.NOTE: Match the arrow mark of the probe with the current direction.
- Fully close the door glass by operating the power window switch and keep the door glass there for approximately 60 seconds.
- With the door glass fully closed, operate the power window switch in the closing direction again. Check how long the current takes to change from a range of 16 A to 34 A, to less than 1 A.
Standard: 4 to 90 seconds
- Check that the door glass moves down when the power window regulator switch is pushed DOWN.
If the result is not as specified, replace the motor assy.
- Set an electrical tester DC 400 A probe to the wire harness of terminal 2.
- Check operation of the regulator motor.

- INSPECT RELAY (Marking: IG1)
- Remove the IG1 relay from the instrument panel J/B.
- Measure the resistance of the relay.
Standard:
TESTER CONNECTION SPECIFICATIONSTester Connection Specified Condition 3 - 5 10 kΩ or higher 3 - 5 Below 1 Ω (when battery voltage is applied to terminals 1 and 2) If the result is not as specified, replace the relay.
