FAIL-SAFE CONTROL Fail-safe control is activated when the actual glass position that is out of the specified value is detected compared to the fully closed position memorized in module in power window motor, or when a malfunction is detected in the encoder signal that indicates UP or DOWN speed and direction of door glass.

Malfunction | Malfunction condition
Pulse direction malfunction (opposite backlash pulse detection) | When a pulse signal indicates that the window is moving in the opposite direction against the power window motor is detected for the specified value or more, while door glass is being operated UP or DOWN.
Pulse sensor (Hall IC) malfunction (one side pulse shut-off detection) | When one pulse signal that is the specified value or more is detected continuously for the specified time or more, while door glass is being operated UP or DOWN.
Both pulse sensor malfunction (both sides pulse shut-off detection) | When both pulse signals are not detected continuously for the specified time or more, while door glass is being operated UP or DOWN.
Glass recognition position malfunction 1 (UP overrun) | When the actual door glass position that is out of the specified value is detected compared to the door glass fully closed position memorized in module, while door glass is being operated UP. (Actual door glass fully closed position is detected to be higher than the memorized position in module for the specified value or more.)
Glass recognition position malfunction 2 (Out of memorized area) | When the actual door glass position that is out of the specified value is detected compared to the door glass fully closed position memorized in module, while door glass is being operated UP. (Actual door glass fully closed position is detected to be lower than the memorized position in module for the specified value or more.)
Glass recognition position malfunction 3 (Full stroke malfunction) | When pulse count that is out of the door glass full stroke value or more is detected, while door glass is being operated UP.
Fully closed position update malfunction | When door glass is continuously operated UP and DOWN for the specified value or more without fully closing door glass.

In fail-safe control, the system changes to a non-initialized condition and the following functions do not operate.

- AUTO UP operation
- Anti-pinch function
- Timer function
- Automatic window adjusting function

When fail-safe control is activated, perform initializing operation to recover. If a malfunction is detected in power window motor, fail-safe control is activated again.
