Auto Reverse Power Window Operation

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

The driver's and front passenger's power window motors incorporate a Hall IC unit (pulser) 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 (pulser), 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: Auto Reverse Power Window Operation

Key Cylinder Operation

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

Keyless Operation

By pressing and holding the UNLOCK button of the keyless transmitter or remote twice within 15 seconds, the windows and panoramic glass roof open. The windows and panoramic glass roof 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 window control unit after doing any of the following

  1. Power window regulator replacement, removal/installation, or repair.
  2. Power window motor replacement, removal/installation, or repair.
  3. Glass 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.
  6. Power is disconnected from the driver's power window master switch or front passenger's power window switch while the power window timer is ON.

Note. If the front passenger's power window has lost power when the key off timer is ON, it cannot be operated from the driver's switch and must be reset from the front passenger's power window switch.

Using the HDS

  1. Connect the HDS to the data link connector (DLC).
  2. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, 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 POWER WINDOW RESET for DRIVER SIDE (PASSENGER SIDE).
  7. Follow the prompts on the screen.
  8. Confirm that the power window control unit is reset by using the power window AUTO UP and AUTO DOWN function.

Without the HDS

Note. Do the manual reset from the power window switch of the affected window.

  1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  2. Move the power window all the way down by using the power window DOWN switch.
  3. Open the door of the affected power window.
  4. Do the following four times before going to step 5 : NOTE: Do each bullet step within 5 seconds of each other. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode. Push and hold the power window DOWN switch. Turn the ignition switch to ON (II) or press the engine start/stop button to select the ON mode. Release the power window DOWN switch.
  5. Confirm that AUTO UP no longer works. If AUTO UP still works, repeat step 4 , paying close attention to the 5 second time limit.
  6. Move the power window all the way down using the power window DOWN switch.
  7. Pull up and hold the power window UP switch until the power window is all the way up, then continue to hold the switch for several seconds.
  8. Confirm that the power window control unit is reset by using the power window AUTO UP and AUTO DOWN function. If the power window still does not work in AUTO, repeat the procedure several times, paying close attention to the 5 seconds time limit between each bulleted step. If the window still does not work, troubleshoot the power window circuit.
