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.

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 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.

Glass recognition position 
malfunction 2

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

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

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 main switch or front power window switch (passenger
side) front power window motor (driver side/passenger side).
