POWER WINDOW CONTROL SYSTEM FAIL-SAFE CHART

  1. POWER WINDOW OPERATION IN FAIL-SAFE MODE

    Tip:

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

    1. The pulse sensor for the jam protection function has problems and the window position or the learned value is abnormal.

      Tip:

      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, fail-safe mode is deactivated and power window operation returns to normal.

    2. Initialization failure

      Tip:

      During initialization of the power window 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.
