Anti-Theft Indicator

NOTE: Replacement of the Passive Anti-Theft System (PATS) transceiver does not require the PATS keys to be programmed into the Instrument Panel Cluster (IPC) again.

NOTE: Make sure any non-Ford remote start systems have been removed from the vehicle before any PATS-related no-start concerns are investigated.

NOTE: A minimum of 2 PATS keys must be programmed into the IPC before the vehicle starts. They do not need to be Integrated Keyhead Transmitter (IKT) keys. Either 2 IKT keys, or 2 standard PATS keys, or a combination of an IKT key and a standard PATS key is sufficient for the vehicle to start.

NOTE: If the IPC and/or the Transmission Control Module (TCM) is being replaced, the parameters must be reset in both modules or the vehicle experiences a PATS no-start. Refer to Passive Anti-Theft System (PATS) Parameter Reset .

PATS uses a visual anti-theft indicator located in the IPC. The indicator proves out for 3 seconds when the ignition key is in the ON or START position under normal operation. If there is a PATS concern, this anti-theft indicator either flashes rapidly or glows steadily when the ignition key is turned to the ON or START position. PATS also flashes the anti-theft indicator every 2 seconds when the ignition key is in the OFF position to act as a visual theft deterrent. Refer to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES for the anti-theft indicator.
