| 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 |
