GENERAL PROCEDURES
Security Access —
Procedure
NOTE: The security access procedure is utilized to obtain passive anti- theft system (PATS) security
access. PATS security access must be granted to erase ignition keys, enable/disable the spare key
programming switch or perform parameter resets for the instrument cluster. The security access
procedure invokes an inherent 10 minute time delay prior to granting security access during which
diagnostic tool must remain connected to the vehicle. Once security access has been granted, a
security access command menu is displayed that offers various command options (refer to PATS
Configuration Command Index).
NOTE: Select only the commands required by the appropriate pinpoint test.
1. From diagnostic tool: Using the Ford Service Function (FSF) card, select the appropriate instrument cluster. Enter SECURITY ACCESS PROCEDURE. This procedure will take 10
minutes to perform, during which the ignition switch must be in RUN and the diagnostic tool
must be connected to the vehicle.
2. After the 10- minute security access procedure has been completed, a new menu will be
displayed with command options. Select only those functions required before exiting out of this
menu. Once exited out of this menu, the security access procedure must be performed again to
perform additional commands.

REMOVAL AND INSTALLATION
Module —
Passive Anti- Theft Transceiver
Removal
1. CAUTION: Electronic modules are sensitive to electrical charges. If exposed to
these charges, damage may result.
Disconnect the battery ground cable (14301).
2. Remove the ignition switch lock cylinder (11582). 1. Insert the ignition key into the ignition switch lock cylinder and turn to the RUN position.
2. Insert a punch in the access hole of the steering column and press the release tab while
pushing out the ignition switch lock cylinder.
3. Unscrew the tilt wheel handle and shank and remove.
4. Remove the instrument panel steering column opening cover. 1. Remove the screws.
2. Remove the LH instrument panel steering column opening cover.

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-
