• Pinch foreign material in the door glass during AUTO-U P operation, and it is the anti-pinch function that low-
ers the door glass 150 mm (5.91 in) or 2 seconds when detected.
• Encoder continues detecting the movement of power window motor and transmits to power window switch
as the encoder pulse signal while power window motor is operating.
• Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
• Front power window switch LH/RH and rear power window control unit LH/RH controls to lower the window glass for 150 mm (5.91 in) or 2 seconds after it detects encoder pulse signal frequency change.
OPERATION CONDITION
• When all door glass AUTO-UP operation is performed ( anti-pinch function does not operate just before the
door glass closes and is fully closed)

The engine start function, door lock function, power di stribution system and NATS-IVIS/NVIS in the Intelligent
Key system are closely related to each other regarding control. Narrow down the functional area in question
by performing basic inspection to i dentify which function is malfunctioning. The vehicle security function can
operate only when the door lock and power distribution system are operating normally. Therefore, it is easy to
identify any factor unique to the vehicle security system by performing the vehicle security operation check
after basic inspection.
1.CHECK DOOR LOCK OPERATION
Check the door lock for normal operation with the Intelligent Key controller and door request switch.
Successful door lock operation with the Intelligent Key and request SW indicates that the remote keyless entry
receiver and inside key antenna required for engine start are functioning normally.
Identify the malfunctioning point by referring to the DLK section if the door cannot be unlocked.
Can the door be locked with the Intelligent Key and door request switch?
YES >> GO TO 2.
NO >> Refer to DLK-210, "
Symptom Table".
2.CHECK ENGINE STARTING
Check that the engine starts when operating the Intelligent Key.
Does the engine start?
YES >> GO TO 3.
NO >> Refer to SEC-115, "
Symptom Table".
3.CHECK STEERING LOCKING
Does the steering lock when operating door switch after switching the power supply from ON position (or ACC
position) to LOCK position?
If door switch is malfunctioning, BC M cannot lock the steering. If BCM does not detect DTC, steering lock unit
is normal.
Does steering lock?
YES >> GO TO 4.
NO >> Refer to DLK-71, "
ComponentFunctionCheck".
4.CHECK IGNITION KNOB SWITCH OPERATION
Press ignition knob to check switch operation.
Does the combination meter display any message?
YES >> GO TO 5.
NO >> Refer to SEC-53, "
Ignition Knob Switch Check".
5.CHECK VEHICLE SECURITY SYSTEM
Check the vehicle security system for normal operation.
The vehicle security function can operate only when t he door lock and power distribution functions are operat-
ing normally.
Therefore, it is easy to identify any factor unique to the vehicle security by performing the vehicle security
operation check after this basic inspection.
>> Go to SEC-7, "
Vehicle Security Operation Check".
