      1. Fail-safe Deactivation Condition


        • When the pulse sensor is normal, to deactivate fail-safe mode, pull up the power window switch to the auto up position and hold it for at least 1 second to fully close the window from the fully open position. As a result, the auto up/down function will return.

    2. Initialization failure

      Tech Tips

      During initialization of the door window regulator ECU, when the window position or initialization complete status cannot be properly read from the EEPROM, the power window control system prohibits the following operations.
