Fail-Safe Control
Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and direction of door glass. Switches to fail-safe control when a signal that is out of the specified value is detected between the fully closed position and the actual position of the glass.
| Malfunction | Malfunction condition |
|---|---|
| Pulse sensor malfunction | 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 sensors malfunction | When both pulse signals are not detected continuously for the specified time or more, while door glass is being operated UP or DOWN. |
| Pulse direction malfunction | When a pulse signal indicating that 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. |
| Glass recognition position malfunction 1 | When the actual door glass position that is out of specified value is detected compared to the door glass fully closed position memorized in module, while door glass is being operated UP or DOWN. |
| Glass recognition position malfunction 2 | When pulse count that is out of the door glass full stroke value or more is detected, while door glass is being operated UP or DOWN. |
If fail-safe control, the system changes to a non-initialized condition and the following function do not operate.
- Auto-up operation
- Anti-pinch function
- Retained power function
When fail-safe control is activated, perform initialization procedure to recover. If a malfunction is detected in power window switch or more, fail-safe control is activated again.
