Passive Anti-Theft System (PATS) PIDs
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. 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 concern. They can also be used to determine if unlimited key mode or customer spare key programming are enabled/disabled.
| PATS PID | Module | PID Description | PID reading required for PATS to be enabled |
|---|---|---|---|
| MASTERKEY | RFA module | Determines if the key in the vehicle is a programmed key. | Present |
| MIN_KEYS | RFA module | Minimum number of programmed keys required. This PID always reads 2. | - |
| N_KEYCODE | RFA module | Number of keys currently programmed into the RFA module. | 2 to 4 |
| PATSENABL | RFA module | Indicates if PATS will allow the ignition to transition on or the engine to start. | Enable |
| BCM_ID | RFA module | Indicates if there is a BCM ID currently stored into the RFA module. | TRUE |
| BCM_VFY | RFA module | Indicates if the BCM ID received by the RFA module matches the BCM ID stored in the RFA module memory. | TRUE |
| START_ENABLD | BCM | Indicates if PATS will allow the engine to start. | Enabled |
| PCM_ID | BCM | Indicates if there is a PCM ID currently stored in the BCM . | Stored |
| PCM_VERIFY | BCM | Indicates if the PCM ID received by the BCM matches the PCM ID stored in the BCM memory. | Yes |
