WINDOW / GLASS: 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 pulse sensor for the jam protection function has problems and the window position or the learned value is abnormal.
HINT
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
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection not operative
* *2: In manual mode and jam protection not operative
Power Window Regulator Switch (for Front Passenger Side, Rear LH and Rear RH)
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection not operative
* *2: In manual mode and jam protection not operative
(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.
1 for driver side:
2 for front passenger side, rear LH and rear RH:
(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 following operations.
Multiplex Network Master Switch
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection not operative
* *2: In manual mode and jam protection not operative
Power Window Regulator Switch (for Front Passenger Side, Rear LH and Rear RH)
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection not operative
* *2: In manual mode and jam protection not operative
(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.
1 for driver side:
2 for front passenger side, rear LH and rear RH:
(c) LIN communication failure
HINT
If the LIN communication line malfunctions (communication stop), the power window control system prohibits the following operations.
Multiplex Network Master Switch
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection operative
* *2: Jam protection not operative
* Remote up/down function does not operate.
Power Window Regulator Switch (for Front Passenger Side, Rear LH and Rear RH)
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection operative
* *2: Jam protection not operative
(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 following operations.
Multiplex Network Master Switch
HINT
* o: Operative
* X: Operation prohibited
* Driver side door window: When there is no jam protection control due to a LIN communication failure, the manual up and auto up functions will not operate.
* Remote switch operation: Not operative during LIN communication failure.
Power Window Regulator Switch (for Front Passenger Side, Rear LH and Rear RH)
HINT
* o: Operative
* X: Operation prohibited
(e) LIN communication failure and displacement of non-detection range in direction window opens 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 following operations.
Multiplex Network Master Switch
HINT
* o: Operative
* *1: Jam protection operative and window reverses direction upon reaching the fully closed position
* *2: Jam protection not operative
* Remote switch operation: Operation is not possible during a LIN communication failure.
Power Window Regulator Switch (for Front Passenger Side, Rear LH and Rear RH)
HINT
* o: Operative
* X: Operation prohibited
* *1: Jam protection operative and window reverses direction upon reaching the fully closed position
* *2: Jam protection not operative
