< ECU DIAGNOSIS INFORMATION >

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.

NONE OF THE POWER WINDOWS CAN BE OPERATED USING ANY SWITCH
