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
