WARNING: This page is about a different car, the 2011 Ford Pickup, 2011 Ford F550 Super Duty, 2011 Ford F450 Super Duty, and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The Passive Anti-Theft System (PATS) disables the engine from starting by disabling the fuel injectors and starter. When the ignition is turned to the RUN or START position, the PATS reads the PATS key and checks the PCM ID. If an unprogrammed PATS key is used or an invalid PCM ID is received, the PATS disables the engine. If there is a PATS concern that caused the engine to be disabled, "STARTING SYSTEM FAULT" is displayed in the message center.
This pinpoint test is intended to diagnose the following:
- Driveability concern
- PATS concern
- Starting system concern
