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

-

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.

•
