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.
