Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Power Window Control System: Initialization
- RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR NOTE:
- Resetting the power window regulator motor (initializing the pulse sensor) is necessary when the cable is disconnected from the battery terminal; when a multiplex network master switch assembly, multiplex network switch assembly, wire harness, power window regulator motor is replaced or removed/installed; or when the fuses are replaced. The AUTO operation function, jam protection function and remote operation function via the multiplex network master switch assembly 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 multiplex network master switch assembly.
- 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 is 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.
- When disconnecting the cable from the negative (-) battery terminal, initialize the following system after the cable is reconnected.
- Turn the engine switch on (IG)
- 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
- 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. If not normal, follow the steps below
- Disconnect the cable negative (-) from the battery terminal for 10 seconds.
- Connect the cable from the negative (-) battery terminal
- Turn the engine switch on (IG)
- Halfway open the power window by pressing the power window switch.
- If the AUTO UP/DOWN function operates normally, reset operations have been completed at this time
If not normal, follow the steps below
