WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: FAIL-SAFE CHART; 2013 MY FR-S [03/2012 -]

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.

HINT
* o: 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 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:





(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:

HINT
* o: 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.

2 For Front Passenger Side:





(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.

(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:

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

(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:

HINT
* o: Operates
* X: Operation prohibited
* *: Operates in pull up the power window switch to the auto up position without jam protection
* Remote switch operation: Operation is not possible during a LIN communication failure.
