WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The Passive Anti-Theft System (PATS) PIDs are a useful tool when diagnosing a PATS concerns. They can also be used to determine if unlimited key mode or customer spare key programming are enabled/disabled.
| BCMPATS PID | PID Description | PID reading required for PATS to be enabled |
|---|---|---|
| PROGRMD_KEY | Determines if the key in the ignition lock cylinder is a programmed key. | Present |
| MIN_KEYS_RQD | Minimum number of programmed keys required. This PID always reads 2. | - |
| KEYS_PROGMD | Number of keys currently programmed into the Body Control Module (BCM) (If unlimited key mode is enabled, this PID will only read 2 regardless of how many keys are programmed). | 2 to 8 |
| START_ENABLD | Indicates if PATS will allow the engine to start. | Enabled |
| PCM_ID | Indicates if there is a PCM ID currently stored into the BCM. | Stored |
| PCM_VERIFY | Indicates if the PCM ID received by the BCM matches the PCM ID stored in the BCM memory. | Yes |
| UNL_KEY_ID | Displays the unlimited key code 8 digit keycode (this PID is not available when unlimited key mode is enabled). | - |
| UNL_KEY_MODE | Indicates if unlimited key mode is enabled/disabled. | - |
