Fail Safe

INFOID:0000000010119935

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 error beyond regulation value is detected between

the fully closed position and the actual position of the glass.

It changes to condition before initialization and the following functions do not operate when switched to fail-

safe control.

• Auto-up operation

• Anti-pinch function

• Retained power function

Error condition

Pulse sensor malfunction

When only one side of pulse signal is being detected for more than the specified value.

Both pulse sensors mal-
function

When both pulse signals have not been detected for more than the specified value during glass
open/close operation.

Pulse direction malfunc-
tion

When the pulse signal that is detected during glass open/close operation detects the opposite con-
dition of power window motor operating direction.

Glass recognition position
malfunction 1

When it detects the error between glass fully closed position in power window switch memory and
actual fully closed position during glass open/close operation is more than the specified value.
