Fail-safe
INFOID:0000000003826036
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.

When the system is switched to fail-safe control, the system becomes un initialized condition and the following
functions do not operate.
 Auto-up operation
 Anti-pinch function
Perform initial operation to recover when switched to fail-safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or front power window motor.
Error Error condition
Pulse sensor malfunction When only one side of pulse signal is being detected for more than the specified value.
Both pulse sensors mal-
functionWhen both pulse signals have not been detected for more than the specified value during glass open/
close operation.
Pulse direction malfunctionWhen the pulse signal that is detected during glass open/close operation detects the opposite condition
of power window motor operating direction.
Glass recognition position
malfunction 1When it detects the error between glass fully closed position in power window switch memory and actual
fully closed position during glass open/close operation is more than the specified value.
Glass recognition position
malfunction 2When it detects pulse count more than the value of glass full stroke during glass open/close operation.
Malfunction of not yet up-
dated closed position of
glassWhen glass open/close operation is continuously performed without fully closing more than the specified
value (approximately 10 strokes).

Diagnosis ProcedureINFOID:0000000003826046
1.PERFORM INITIALIZATION PROCEDURE
Initialization procedure is executed and operation is confirmed.
Refer to PWC-6, "
ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Special Repair Require-
ment".
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK ENCODER CIRCUIT
Check encoder circuit.
Refer to PWC-29, "
Component Function Check".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace the malfunctioning parts.
3.CONFIRM THE OPERATION
Confirm the operation again.
Is the result normal?
YES >> Check intermittent incident. Refer to GI-35, "Intermittent Incident".
NO >> GO TO 1.
