Fail-Safe Chart [06/2016 - ]

  1. POWER WINDOW OPERATION IN FAIL-SAFE MODE 

    HINT: 

    If the pulse sensor built into the 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. Power window switch LED control

        HINT: 

        During initialization of the power window regulator motor ECU, when the window position or initialization complete status cannot be properly read from the EEPROM during fail-safe mode, the LED illuminates as shown in the illustration.

      2. 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

      HINT: 

      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:

      HINT: 

      • ◦: Operates
      • X: Operation prohibited
      • *: Operates in pull up the power window switch to the auto up position without jam protection
      1. Power window switch LED control

        HINT: 

        • During normal operation (fail-safe is not operating) the LED illuminate as shown in the illustration.
        • When a LIN communication system failure occurs, the LED will blink in a pattern of being on for 1.4 seconds, and then off for 1.4 seconds.
        • If another failure occurs at the same time as the LIN failure, the pattern of being on for 0.7 seconds and off for 0.7 seconds will take precedence.

    3. LIN communication failure

      HINT: 

      If the LIN communication line malfunctions (communication stop), the power window control system prohibits the operations as follows:
