FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and
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.
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
• Retained power 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 switch or front power window motor.

If any of the following operations are performed, the initialization is necessary for normal operation of anti-
pinch function.
• Disconnection and connection of battery cable from negative terminal.
• When power window main switch or front power window switch (passenger side) replaced.
• Electric power supply to power window main switch or front power window switch (passenger side) or power
window motor (driver side/passenger side) is interrupted by blown fuse or disconnection and connection of

Work Procedure
INFOID:0000000008463231
1.
CHECK ANTI-PINCH FUNCTION
1.
Fully open the door window.
2.
Place a piece of wood near fully closed position.
3.
Close door glass completely with AUTO-UP.
4.
Check the following conditions.
-
Check that glass lowers for approximately 150 mm (5.9 in) without pinching piece of wood and stops.
-
Check that glass does not rise not when operating the power window main switch or front power window
switch (passenger side) while lowering.
CAUTION:
•
Perform initial setting when AUTO-UP operation or anti-pinch function does not operate nor-
mally.
•
Check that AUTO-UP operates before inspection when system initialization is performed.
•
Do not check with hands and other body parts because they may be pinched. Do not get
pinched.
