POWER WINDOW CONTROL SYSTEM FAIL-SAFE CHART


  1. POWER WINDOW OPERATION IN FAIL-SAFE MODE

    Tech Tips

    If the pulse sensor built into a power window regulator motor malfunctions, the power window control system enters fail-safe mode.


    1. The power window control system prohibits the following power window operations when the pulse sensor for the jam protection function has problems and the window position or the learned value is abnormal.

      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 power window regulator motor ECU, when the window position or initialization complete status cannot be properly read from the EEPROM, the power window control system prohibits the operations as follows.
