Inspection Procedure

CHECK FUSE
1. Check if the P FR DOOR 20 A, ECU B 7.5 A and IG1 7.5 A fuses are normal.
1. NG: REPLACE FUSE
2. OK: GO TO NEXT STEP.
CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSY
1. Check the power source voltage.
  1. Disconnect the master switch connector.
  2. Check the voltage of each terminal of the vehicle's side connector of the master switch.

1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
2. OK: GO TO NEXT STEP.
CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSY
1. Check the GND.
  1. Disconnect the master switch connector.
  2. Check the continuity between terminal 2 (GND) of the vehicle's side connector of the master switch and the body ground.
    Standard: Continuity (constant)

1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR
2. OK: GO TO NEXT STEP.
CHECK POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER'S SIDE)
1. Disconnect the master switch connector.
2. Inspect the door glass operation when the battery voltage is applied between terminals 1 (UP) and 11 (DN) of the vehicle's side connector of the master switch.
  Standard:

2. NG: GO TO NEXT STEP.
INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER SIDE)
1. Inspect the power window regulator motor assy LH (Driver side) operation.
  NOTE:
  - Do not apply the battery voltage, because the pulse sensor and limit switch could be damaged if the battery voltage is applied to terminals 2,3 and 6 of the power window regulator motor connector.
  - Be sure to reset the power window regulator motor (initial position setting of limit switch) when the driver's side power window regulator motor is installed to the regulator. See POWER WINDOW / ROOF INITIALIZATION PROCEDURES .
  1. Check that the motor operates smoothly when the battery positive voltage is applied to each terminal of the connector.
    Standard:

2. Inspect the PTC operation inside the power window regulator motor.
  NOTE: The inspection should be performed with the power window regulator and door glass installed to the vehicle.
  1. Set a DC 400 A probe of the electrical tester in the wire harness of terminal 4 or 5.
    NOTE: Match the arrow mark of the probe with the current direction.
  2. Set the door glass in the fully closed position.
  3. When 60 seconds have elapsed after the door glass is fully closed, check now long the current takes to charge, from approximately 16 - 34 A into 1 A or less, when the power window switch is turned UP once again.
    Standard: Approximately 4 - 90 seconds
  4. When approximately 60 seconds have elapsed after the inspection of the current cut-off, check that the door glass goes down when the power window regulator switch is turned DOWN.
  1. NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSY LH
  2. OK: REPAIR OR REPLACE HARNESS AND CONNECTOR
