Fail-safe

INFOID:0000000006217279

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.

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.

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 mal-
function

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 malfunc-
tion

When a pulse signal indicating that window is moving in the opposite direction against the power win-
dow 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.
