Power Window Control System

INSPECTION







1. INSPECT REAR DOOR POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.

2. INSPECT POWER WINDOW SWITCH CIRCUIT
Refer to Body Control Systems; Testing and Inspection.







3. INSPECT POWER MAIN RELAY CONTINUITY
If continuity is not as specified, replace the relay.




4. Driver's Door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the motor turns clockwise.




b. Reverse the polarity and check that the motor turns counterclockwise.
If operation is not as specified, replace the power window motor.

NOTE: Since the jam protection may not work properly, be sure to conduct procedures described in "HOW TO RESET POWER MOTOR (RESET AND PULSE SWITCH)" after this inspection.




5. Passenger's Door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the motor turns clockwise.




b. Reverse the polarity and check that the motor turns counterclockwise.
If operation is not as specified, replace the power window motor.

NOTE: Since the jam protection may not work properly, be sure to conduct procedures described in "HOW TO RESET POWER MOTOR (RESET AND PULSE SWITCH)" after this inspection.




6. Rear Right Door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminals 2, and check that the motor turns clockwise.




b. Reverse the polarity and check that the motor turns counterclockwise.
If operation is not as specified, replace the power window motor.




7. Rear Left Door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the motor turns clockwise.




b. Reverse the polarity and check that the motor turns counterclockwise.

If operation is not as specified, replace the power window motor.




8. Front Door:
INSPECT PTC OPERATION
a. Disconnect the connector from the wire harness side connector.
b. Connect the negative (-) lead from the ammeter to terminal 1 of the motor side connector and the positive (+) lead to negative terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 2 of the motor side connector, and raise the window to the fully closed position.




d. Continue to apply voltage and check that the current changes from approximately 14 A to less than 1 A within 4 to 90 seconds.
e. Disconnect the leads from the terminals.
f. Approximately 90 seconds later, connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the window begins to goes down.
If operation is not as specified, replace the power window motor.




9. Rear Door:
INSPECT PTC OPERATION
a. Disconnect the connector from the wire harness side connector.
b. Connect the negative (-) lead from the ammeter to terminal 1 of the motor side connector and the positive (+) lead to negative terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 2 of the motor side connector, and raise the window to the fully closed position.




d. Continue to apply voltage and check that the current changes from approximately 14 A to less than 1 A within 4 to 90 seconds.
e. Disconnect the leads from the terminals.
f. Approximately 90 seconds later, connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the window begins to goes down.
If operation is not as specified, replace the power window motor.

10. INSPECT JAM PROTECTION FUNCTION

NOTE: Be careful not to be caught any part of your body when checking.

HINT: When performing resetting of the limit switch, do checking after repeating up and down of the glass with automatic operation.

a. Confirmation of AUTO up operation: Confirm that the window will be fully closed with AUTO up operation.
b. Checking operation of the jam protection function:
1. Move up the window with AUTO up operation and check that the window will go down when it touches the inserted handle of the hammer.
2. Confirm that the window will then stop going down about 200 mm (7.87 in.).

HINT: When removing the glass, glass guide, regulator, etc.. be sure to perform checking of the jam protection function.

If the jam protection is not functioning properly, adjust the power window motor limit switch and pulse switch.
