POWER WINDOW MOTOR

Fail-Safe

INFOID:0000000009159950

FAIL-SAFE CONTROL

Fail-safe control is activated when the actual glass position that is out of the specified value is detected com-
pared to the fully closed position memorized in module in power window motor, or when a malfunction is
detected in the encoder signal that indicates UP or DOWN speed and direction of door glass.

In fail-safe control, the system changes to a non-initialized condition and the following functions do not oper-
ate.
• AUTO UP operation
• Anti-pinch function
• Timer function
• Automatic window adjusting function
When fail-safe control is activated, perform initializing operation to recover. If a malfunction is detected in
power window motor, fail-safe control is activated again.

Malfunction

Malfunction condition

Pulse direction malfunc-
tion (opposite backlash
