POWER WINDOW MAIN SWITCH

Fail Safe

INFOID:0000000010735365

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

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

drive direction of power window motor is operating in the opposite direction for the specified time or
longer
