SYSTEM

Fail Safe

INFOID:0000000010735208

FAIL-SAFE CONTROL

Power window main switch switches power window operation to fail-safe control when malfunction is detected
in encoder signal that detects up/down speed and direction of door glass. Power window main switch switches
power window operation 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 power window
main switch switched power window operation to fail-safe control.
• Auto-up operation
• Anti-pinch function

Perform initial operation to recover when power window main switch switched power window operation to fail-
safe mode. However, it power window main switch switched power window operation back to fail-safe control
when malfunction is found in power window main switch or front power window motor (driver side).

Error

Error condition

Pulse sensor malfunction

When only one side of pulse signal is detected for more than the specified time during glass open/
close operation

Both pulse sensors mal-
function

When both pulse signals are not detected for more than the specified time during glass open/close 
operation.

Pulse direction malfunc-
tion

When the pulse signal detected during glass open/close operation continues in the condition that the 
drive direction of power window motor is operating in the opposite direction for the specified time or 
longer

Glass recognition position 
malfunction 1

When it detects the error between glass fully closed position in power window main 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.
