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
pulse detection)
When a pulse signal indicates that the window is moving in the opposite direction against the power
window motor is detected for the specified value or more, while door glass is being operated UP or
DOWN.
Pulse sensor (Hall IC)
malfunction (one side
pulse shut-off detection)
When one pulse signal that is the specified value or more is detected continuously for the specified
time or more, while door glass is being operated UP or DOWN.
Both pulse sensor mal-
function (both sides pulse
shut-off detection)
When both pulse signals are not detected continuously for the specified time or more, while door
glass is being operated UP or DOWN.
Glass recognition position
malfunction 1 (UP over-
run)
When the actual door glass position that is out of the specified value is detected compared to the
door glass fully closed position memorized in module, while door glass is being operated UP. (Actual
door glass fully closed position is detected to be higher than the memorized position in module for
the specified value or more.)
Glass recognition position
malfunction 2 (Out of
memorized area)
When the actual door glass position that is out of the specified value is detected compared to the
door glass fully closed position memorized in module, while door glass is being operated UP. (Actual
door glass fully closed position is detected to be lower than the memorized position in module for the
specified value or more.)
Glass recognition position
malfunction 3 (Full stroke
malfunction)
When pulse count that is out of the door glass full stroke value or more is detected, while door glass
is being operated UP.
Fully closed position up-
date malfunction
When door glass is continuously operated UP and DOWN for the specified value or more without
fully closing door glass.
