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.

Washers
When the GEM detects the ignition switch circuits are in RUN or ACC states, and the GEM detects a
WASH request from the wiper delay/wash circuits, the GEM will activate the washer pump relay circuit
for as long as the request is present up to 10 seconds.
Activation of the washer pump when in INTERVAL or OFF is delayed until a wash request is active for
a minimum amount of time. In this scenario, the wash request must be present continuously for at least
210 ms. This allows a wash request that is present for less than 210 ms, to provide additional
functionality by initiating a single wipe, called "mist wipe". The mist wipe function is a single wipe at low
speed without activating the washer motor.
When in LOW or HIGH, any WASH request, regardless of the length of time it is present, will activate
the washer pump. When in INTERVAL or OFF mode, upon deactivation of the washer motor, this
feature shall provide two wipes at low speed before returning to the INTERVAL or OFF state as
defined by the inputs. These additional wipes are provided to clear residual washer fluid from the front
windshield.
Inspection and Verification
1. Verify the customer concern by operating the wiper/washer system.
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 diagnostic tool does not communicate with the vehicle:
zCheck that the program card is correctly installed.
z Check the connections to the vehicle.
z Check the ignition switch position.
4. If diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If diagnostic tool responds with: zCKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418 -
00 .
z NO RESPONSE/NOT EQUIPPED for GEM, go to Pinpoint Test A.

WARNING: It is important that the bolt/anchor be securely tightened to specification.
Otherwise, the child's safety seat may not be correctly secured and the child could be injured
in case of a sudden stop or accident.
Instructions for installing the child safety belt anchor tether kit are included in the kit with the tether

GENERAL PROCEDURES
Replacement of the Weld Nut and Reinforcement
1. NOTE: The following is for Coupe, Front and Rear, and Convertible rear only.
NOTE: If the safety belt anchor nuts or reinforcements are stripped or missing, a new
nut/reinforcement plate must be installed.
Expose the suspect anchor point.
2. Drill out two 8 mm (0.32 in) (5/16 inch) diameter access holes adjacent to the weld nut clearance hole.
3. Thread a length of copper welding wire through the clearance hole and position to secure the weld nut and washer.
4. Use MIG wire feed welder and plug weld a 7/16 inch weld nut and standard washer in place at the two 8 mm (5/16 inch) holes.
5. Metal finish as necessary.
6. Install the restraint system.
7. Carry out the Functional Test. For additional information, refer to Safety Belt System in this
section.
