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 if: 1) the battery terminal cable is disconnected; 2) the power window regulator master switch, wire harness, power window regulator switch, window regulator, and power window regulator motor are replaced or removed/installed; 3) the DC CUT or MPX-B fuses are replaced. If resetting is not performed, the master switch will not be able to operate the AUTO operation function, jam protection and remote UP/ DOWN function.
- Turn the engine switch on (IG).
- Open the power window halfway by pressing the power window switch.
- Fully pull the switch up until the power window is fully closed and continue to hold the switch for at least 1 second.
- Check that the AUTO UP/DOWN function operates normally.
HINT:
If the AUTO UP/DOWN function operates normally, reset operations are completed. If abnormal, perform the following 3 steps.
- Disconnect the cable from the negative (-) battery terminal for 10 seconds or more.
- Reconnect the cable.
- Perform initialization from the first 4 steps again.
HINT:
If a condition where an initialization is necessary occurs (see 1), 2) and 3) above), the initialization procedures above are performed, but the remote UP/DOWN function does not operate, the power window regulator master switch may have a malfunction.
