Power Window System Acura TL IV

Scheme 1

Scheme 2

Auto Reverse Power Window Operation

The system is composed of the driver's MICU, passenger's MICU unit, door multiplex control unit (built into the power window master switch), front passenger's power window control unit (built into the front passenger's switch), and power window motors

The driver's and front passenger's power window motors incorporate a Hall IC unit which generates pulses during the motor's operation and sends pulses to the driver's and passenger's power window control units As soon as the power window control units detect a change in the pulse frequency from the Hall IC unit, the power window control units make the power window motor stop and reverse This prevents pinching your hand or fingers during auto-up operation The auto reverse function does not work when the power window master switch is held in the closed position

Scheme 3

Key Cylinder Operation

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

Keyless Operation

By pressing and holding the UNLOCK button of the keyless transmitter, or remote a second time 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

Reset the power windows after doing any of the following actions

1. Power window regulator replacement, removal/installation, or repair
2. Power window motor replacement, removal/installation, or repair
3. Window run channel replacement or removal/installation
4. Front passenger's power window switch replacement or removal/installation"
5. Door glass replacement, removal/installation, or repair
