Fail-Safe Chart [08/2013 - ]
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
- POWER WINDOW OPERATION IN FAIL-SAFE MODE
- The power window control system prohibits the following power window operations when the pulse sensor for the jam protection function is malfunctioning and the window position or the learned value is abnormal.
HINT:
If the pulse sensor built into the power window regulator motor malfunctions, the power window control system enters fail-safe mode.

- 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 opened position. As a result, the auto up and down functions will return.
- 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 operation as follows:
