WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: FAIL-SAFE CHART

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.

(a) 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.

Multiplex Network Master Switch Assembly





HINT
* o: Operates
* X: Operation prohibited
* *: Operates in manual mode without jam protection

Power Window Regulator Switch Assembly (for Front Passenger Side, Rear LH and Rear RH Sides)





HINT
* o: Operates
* X: Operation prohibited
* *: Operates in manual mode without jam protection

(1) Power window switch LED control

HINT
During normal operation (fail-safe is not operating), or during fail-safe mode when there is a pulse sensor malfunction or the window position or learned value is abnormal, the LED illuminates as shown in the illustration.

for driver side:





for front passenger side, rear LH and rear RH sides:





(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.

(b) 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:

* *: Operates in manual mode without jam protection

(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.

for front passenger side, rear LH and rear RH sides:





(c) LIN communication failure

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

HINT
* o: Operates
* X: Operation prohibited
* *: Jam protection can operate
* Remote up/down function does not operate.

Power Window Regulator Switch Assembly (for Front Passenger Side, Rear LH and Rear RH Sides)





HINT
* o: Operates
* X: Operation prohibited
* *: Jam protection can operate

(d) LIN communication failure and pulse sensor failure

HINT
If the LIN communication line malfunctions (communication stop) and the pulse sensor for the jam protection function has problems, the power window control system prohibits the operations as follows:

Multiplex Network Master Switch Assembly





HINT
* o: Operates
* X: Operation prohibited
* Driver door window: When the jam protection function does not operate due to a LIN communication failure, the manual up and auto up functions will not operate.
* Remote switch operation: Not operative during a LIN communication failure.

Power Window Regulator Switch Assembly (for Front Passenger Side, Rear LH and Rear RH Sides)





HINT
* o: Operates
* X: Operation prohibited

(e) LIN communication failure and abnormal window position learned value or initialization failure

HINT
If the LIN communication line malfunctions (communication stop) and the window position or the learned value is abnormal, the power window control system prohibits the operations as follows:

Multiplex Network Master Switch Assembly





HINT
* o: Operates
* *: Jam protection can operate and window reverses upon reaching the fully closed position
* Remote switch operation: Operation is not possible during a LIN communication failure.
