Theft — Passive Anti- Theft System (PATS)
Refer to Wiring Diagrams Cell 112 , Anti-
Theft for schematic and connector information.
Refer to Wiring Diagrams Cell 60 , Instrument Cluster for schematic and connector information.
Inspection and Verification
NOTE: PATS must be reconfigured upon installment of a new instrument cluster. Refer to Section 418 -
00 .
1. Verify the customer concern by duplicating the condition.
2. Visually inspect for obvious signs of mechanical and electrical damage.
3. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the
diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
zcheck that the program card is correctly installed.

Principles of Operation
Power Window Control
NOTE: Battery power and ground must be removed before disconnecting the GEM connectors to
avoid setting false DTCs.
The driver power window one- touch down operation is controlled by the generic electronic module
(GEM). This feature functions only when the ignition switch is in the RUN or ACCY positions. The GEM
determines ignition switch position by monitoring the key- in ignition, RUN/ACCY and RUN/START
circuits. The one-touch down operation is requested of the GEM by momentarily pressing the driver
window regulator control switch DOWN for 62 ms to 320 ms. The GEM uses the initial voltage input
from the down switch to begin the one- touch down operation. If the voltage input was less than 320
ms, the GEM will maintain the voltage supply to the motor down circuit. The GEM will maintain the
operation until:
zseven seconds expires.
z motor stall is detected by monitoring the current draw.
z a voltage input is received by the GEM on either the up or down switch circuits.
The ground for one- touch down operation does not pass through the GEM. The ground is supplied
through the driver window regulator control switch as with normal operation. If the GEM continues to
see voltage on the down circuit for more than 320 ms after initial activation the GEM will not effect
operation. The down circuit through the GEM is a direct connection to the motor in its normal state.
This allows the driver window regulator control switch to control the motor for normal operation.
The passenger window motors are hardwired directly to the window regulator control switches. SECTION 501-
