POWER WINDOW CONTROL SYSTEM - INITIALIZATION
| RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR |
Resetting the power window motor (initializing the pulse sensor) is necessary when the battery terminal is disconnected; when the power window regulator master switch, power window regulator 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 regulator master switch do not operate without resetting.
Be sure to reset the power window regulator motors using the power window switch on each door because the motors cannot be reset by remote operation using the power window master switch.
In order to prevent a large amount of current from flowing in the wires, do not simultaneously reset 2 or more power window regulator motors.
If the power window switch has been continuously operated for a long time, the power window regulator motor will stop so that no additional load will 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.

Halfway open the power window by pressing the power window switch.
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.
