IGN Counter

0 - 39

The number of times that ignition switch is turned ON after DTC is detected
• The number is 0 when a malfunction is detected now.
• The number increases like 1

→

2

→

3...38

→

39 after returning to the normal condition

whenever ignition switch OFF

→

ON.

• The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

Fail-safe

INFOID:0000000006217273

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 a signal that is out of the specified value is detected
between the fully closed position and the actual position of the glass.

If fail-safe control, the system changes to a non-initialized condition and the following function do not operate.
• Auto-up operation
• Anti-pinch function
• Retained power function

When fail-safe control is activated, perform initialization procedure to recover. If a malfunction is detected in
power window switch or more, fail-safe control is activated again.

Malfunction

Malfunction condition

Pulse sensor malfunction

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 sensors mal-
function

When both pulse signals are not detected continuously for the specified time or more, while door
glass is being operated UP or DOWN.

Pulse direction malfunc-
tion

When a pulse signal indicating that window is moving in the opposite direction against the power win-
dow motor is detected for the specified value or more, while door glass is being operated UP or
DOWN.

Glass recognition position
malfunction 1

When the actual door glass position that is out of specified value is detected compared to the door
glass fully closed position memorized in module, while door glass is being operated UP or DOWN.

Glass recognition position
malfunction 2

When pulse count that is out of the door glass full stroke value or more is detected, while door glass
is being operated UP or DOWN.
