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-
