DIAGNOSIS AND TESTING
Anti-
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.

4. If the 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 RESP/NOT EQUIP for instrument cluster, go to Pinpoint Test A.
z SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs),
erase the continuous DTCs and carry out self- test diagnostics for the instrument cluster.
6. If the DTCs retrieved are related to the concern, go to Instrument Cluster Diagnostic Trouble Code (DTC) Index to continue diagnostics.
7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics.

PINPOINT TEST G: THE ANTI - THEFT SYSTEM DOES NOT OPERATE Test Step Result / Action to Take
NOTE:
Large metallic objects, electronic debit transponder devices or a second key on the same
key ring as the PATS ignition key may cause vehicle starting problems and record DTCs under
certain conditions. If a fault cannot be identified, examine the customer's key for such objects or
devices. If present, inform the customer that they need to keep these objects from touching the
PATS ignition key while starting the engine. These objects and devices cannot damage the
PATS ignition key, but can cause a momentary problem if they are too close to the key during
engine start. If a problem occurs, turn ignition OFF and restart the engine with all other objects
on the key ring held away from the ignition key. Check to ensure the encoded ignition key used
by the customer is an approved Ford encoded ignition key (encoded ignition keys from Rotunda,
Ilco, Curtis, or Strattec are approved Ford encoded ignition keys). F1 USE THE DTCS FROM THE INSTRUMENT
