Pinpoint Test F: The Anti-Theft Indicator Is Always/Never On - Vehicle Starts Normally
Normal Operation
The Passive Anti-Theft System (PATS) uses an anti-theft indicator located in the Instrument Cluster (IC). This anti-theft indicator proves out for 3 seconds when the key is turned to ON or START. If there is a PATS concern, this indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to ON or START. PATS also flashes the anti-theft indicator every 2 seconds at key OFF to act as a visual theft deterrent.
This pinpoint test is intended to diagnose the following:
- Anti-theft indicator (part of the IC
- IC
PINPOINT TEST F: THE ANTI-THEFT INDICATOR IS ALWAYS/NEVER ON - VEHICLE STARTS NORMALLY
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Large metallic objects, electronic devices on the key ring that can be used to purchase gasoline or similar items, or a second key on the same key ring as the PATS key may cause a vehicle starting concern and record DTCs under certain conditions. If a fault cannot be identified, examine the customer key ring for such objects or devices. If present, inform the customer that they need to keep these objects from touching the PATS key while starting the engine. These objects and devices cannot damage the PATS key, but can cause a momentary concern if they are too close to the key during engine start. If a concern occurs, turn the ignition off and restart the engine with all other objects on the key ring held away from the ignition key. Check to make sure the PATS key used by the customer is an approved Ford PATS key. (PATS keys from Ford, Rotunda, Strattec, or Huf are approved Ford PATS keys.)

F1 CHECK THE ANTI-THEFT INDICATOR FOR CORRECT OPERATION
- Ignition OFF.
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IC DataLogger.
- Operate the IC active command THEFT_LMP to ON, then OFF.
- Does the anti-theft indicator illuminate, then turn off?
Yes
GO to F2.
No
INSTALL a new IC. REFER to Instrument Panel, Gauges and Warning Indicators. RESET the parameters in both the IC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS). PROGRAM the PATS keys into the new IC. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. REPEAT the self-test.
-------------------------------------------------
F2 CHECK FOR CORRECT IC OPERATION
- Disconnect the IC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IC connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes
INSTALL a new IC. REFER to Instrument Panel, Gauges and Warning Indicators. RESET the parameters in both the IC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS). PROGRAM the PATS keys into the new IC. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. REPEAT the self-test.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
