Toyota Sienna Service Manual: Initialization

NOTICE:

•  Resetting the power window motor (initializing the pulse sensor) is necessary when the battery terminal is disconnected; when the master switch, wire harness, power window regulator and power window motor are replaced or removed/installed; or when the fuses are replaced. AUTO operation function, jam protection function and remote operation function via the power window master switch do not operate without resetting.
•  If the AUTO switch (driver side switch) of the master switch has been continuously operated for a long time, the power window motor will stop so that no additional load can be applied to the motor.

  Continuing to operate the switch even after the motor has stopped will cause the switch to blink while restricting the AUTO UP/DOWN function and the remote UP/DOWN function. If this happens, reset the motor again after several minutes have passed.

•  Whenever disconnecting the battery terminal, reset all the other systems besides the power window control system.

1. RESET POWER WINDOW REGULATOR MOTOR (DRIVER SIDE)

1.  Turn the ignition switch ON.
2.  Halfway open the power window by pressing the power window switch.
3.  Fully pull up the switch until the power window is fully closed and continue to hold the switch for approx. 1 second after the power window is fully closed.
4.  Check that the AUTO UP/DOWN function operates normally.

   If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time.

1.  Disconnect the negative battery terminal for 10 seconds.
