System Description

Auto Reverse Operation

The system is composed of the power window master switch and the driver's power window motor.

The driver's power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the driver's power window control unit. As soon as the power window control unit detects no pulses from the pulser (the window stops short of full travel), the driver's power window control unit makes the power window motor stop and reverse. If the window is more than halfway closed, it will reverse to half open position. If the window is less than halfway closed, it will stop and reverse about 2 inches. This is to prevent pinching an obstacle during auto-up operation. The auto reverse operation is not active when the switch is held in the up position.

Resetting the Power Window Control Unit

Resetting the driver's power window is required when any of the following have occurred:

• Power window regulator replacement or repair
• Power window motor replacement or repair
• Window run channel replacement or repair
• Driver's door glass replacement or repair
• Power is removed from the power window control unit while the power window timer is ON
• Power window master switch replacement

1. Turn the ignition switch ON (II).

2. Move the driver's window all. the way down by using the driver's window DOWN switch.

3. Open the driver's door.

NOTE: Steps 4-7 must be done within 5 seconds of each other.

4. Turn the ignition switch OFF.

5. Push and hold the driver's window DOWN switch.

6. Turn the ignition switch ON (II).

7. Release the driver's window DOWN switch.

8. Repeat step 4-7 three more times.

9. Wait for at least 1 second.

10. Check if the AUTO UP and AUTO DOWN functions still work. If they do, go back to step 1 (the AUTO function has not been cleared; repeat the clear procedure again). If they do not, go to step 11.

11. Move the driver's window all the way down by using the driver's window DOWN switch.

12. Pull up and hold the driver's window UP switch until the window reaches the fully closed position, then continue to hold the switch for 1 second.

13. Confirm that the power window control unit is reset by using the driver's window AUTO UP and AUTO DOWN functions.

If the window still does not work in AUTO, repeat the procedure several times, paying close attention to the 5 second time limit between steps. If it still does not work, refer to the master switch input test.

Master Switch Input Test

NOTE: The power window control unit is built into the power window master switch.

1. Remove the power window switch panel.

2. Disconnect the 22P connector (A) from the master switch (B).

3. Inspect the connector and socket terminals to be sure they are all making good contact.

• If the terminals are bent, ,loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, go to step 4.

4. With the connector still disconnected, do these input tests at the connector.

• If any test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, go to step 5.

5. Reconnect the 22P connector to the power window master switch, and do these input tests at the connector.

• If any test indicates a problem, find and correct the cause, then recheck the system.
• If all the input tests prove OK, the control unit must be faulty; replace the power window master switch, and go to step 6.

6. Resetthe power window control unit.

Driver's Power Window Motor Test

Motor Test

1. Remove the door panel, and disconnect the connectors.

2. Test the motor in each direction by connecting battery power and ground to the power window master switch 22P connector according to the table.

3. If the motor does not run or fails to run smoothly, go to step 4.

4. Disconnect the 6P connector from the driver's power window motor.

5. Check for continuity between the power window master switch 22P connector No.9 and No. 10 terminals and the driver's power window motor 6P connector No.1 and No.4 terminals, respectively.

7. Do the power window master switch input test No.5, No.6, No.7, and No. 16 terminals.

Passenger's Power Window Motor Test

1. Remove the door panel, and disconnect the connectors.

2. Test the motor in each direction by connecting battery power and ground to the passenger's power window switch 8P connector according to the table.

3. If the motor does not run or fails to run smoothly, go to step 4.

4. Disconnect the 6P connector (A) from the passenger's power window motor (B).

5. Check for continuity between the passenger's power window switch 8P connector No.7 and No.8 terminals and the passenger's power window motor 2P connector No.1 and No.2 terminals.

6. If the wire harness is OK, replace the appropriate power window motor.

Master Switch Test

1. Remove the driver's door panel.

2. Disconnect the 22P connector (A) from the power window master switch (B).

3. Check for continuity between the terminals in each switch position according to the tables.

Driver's Switch

The driver's switch is combined with the control unit, so you cannot isolate the switch to test it.

Instead, run the master switch input test procedures. If the tests are normal, the driver's switch is faulty. Replace the switch.

4. If the continuity is not as specified, replace the switch.

Passenger's Power Window Switch Test

1. Remove the passenger's door panel.

3. Check for continuity between the terminals in each switch position according to the table.

4. Connect battery power to the No.4 terminal and ground the No.7 (or No.8) terminal. The switch light should come on.

5. If the continuity or switch light tests is not as specified, replace the switch.
