[LH & RH FRONT AUTO UP/DOWN]

POWER WINDOW MAIN SWITCH

Fail Safe

INFOID:0000000009176186

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

Error

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 malfunction

When the pulse signal that is detected during glass open/close operation detects the opposite condition
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.

Glass recognition position
malfunction 2

When it detects pulse count more than the value of glass full stroke during glass open/close operation.

Malfunction of not yet up-
dated closed position of
glass

When glass open/close operation is continuously performed without fully closing more than the specified
value (approximately 10 strokes).
