Power Window System Acura TL III

Scheme 109

Anti-pinch Power Window Operation

The system is composed of the power window master switch, front passenger's power window switch, front passenger's power window control unit and the driver's and front passenger's power window motors.

Driver's Window

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 driver's power window control unit makes the power window motor stop and reverse. This is to prevent pinching your hand or fingers during auto-up operation. The anti-pinch is not active when the switch is held in the up position.

Front Passenger's Window

The front passenger's power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the front passenger's power window control unit. As soon as the power window control unit detects no pulses from the pulser, the front passenger's power window control unit makes the power window motor stop and reverse. This is to prevent pinching your hand or fingers during auto-up operation. The anti-pinch is not active when the switch is held in the up position.

Scheme 110

Key Cylinder Operation

With the key inserted in the driver's door key cylinder, turn the key a second time and hold it within 15 seconds to operate the windows and moonroof (clockwise to open, counterclockwise to close). The windows and moonroof stop moving when the key is released. The anti-pinch operation is not active when closing the windows and moonroof with the key cylinder.

Keyless Operation

By pressing the UNLOCK button of the keyless transmitter a second time and hold within 15 seconds, the windows and moonroof open. The windows and moonroof stop moving when the UNLOCK button is released. The windows do not close with the LOCK button.

Resetting the Power Window Control Unit

Resetting the driver's or front passenger's power window is required when any of the following have occurred

1. Power window regulator replacement or repair
2. Power window motor replacement or repair
3. Window run channel replacement or repair
4. Door glass replacement or repair
5. Power is removed from a power window control unit while the power window timer is ON.

Using the HDS

1. Connect the Honda Diagnostic System (HDS) to the vehicle's DLC.
2. Turn the ignition switch ON (II), then enter the vehicle's VIN and mileage at the prompts.
3. Select "Body Electrical" from the "System Selection" menu.
4. From the "Body Electrical System Select" menu, select "Power Windows".
5. From the "Mode" menu, select "Adjustment".
6. From the "Adjustment" menu, select "Window P Reset" for driver's side (passenger's side) window.
7. Follow the prompts on the screen.
8. Confirm that the power window control unit is reset by using the driver's (passenger's) window AUTO UP and AUTO DOWN function.

Scheme 111

1. Turn the ignition switch ON (II).
2. Move the driver's (passenger's) window all the way down by using the driver's (passenger's) window DOWN switch.
3. Open the driver's (passenger'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 (passenger's) window DOWN switch.

10. Confirm that AUTO UP and AUTO DOWN do not work. If AUTO UP and DOWN work, go back to step 1.
11. Move the driver's (passenger's) window all the way down by using the driver's (passenger's) window DOWN switch.
12. Pull up and hold the driver's (passenger'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 (passenger's) window AUTO UP and AUTO DOWN function. 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, go to B-CAN System Diagnosis Test Mode A (see «TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A»(/acura/tl/iii-2003-2006/remont/communication-devices/#multiplex-intergrated-control-system__troubleshooting-b-can-system-diagnosis-test) ).
