Fail Safe
INFOID:0000000005147242
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 cont rol 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
Perform initial operation to recover when switched to fail- safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or in motor.
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 (approximate
ly 10 strokes).
