PATS Parameter Identifications (PIDs)
In conjunction with Diagnostic Trouble Codes (DTCs), the PATS Parameter Identifications (PIDs) are a useful tool when diagnosing PATS concerns.
BCMPID Chart
| Acronym | Name | Description |
|---|---|---|
| KEYS_PROGMD | (PATS) number of ignition key codes supported | Number of keys currently programmed into the BCM (if unlimited mode is enabled, this PID always reads 2 regardless of how many keys are programmed). |
| MIN_KEYS_RQD | Minimum number of keys required | Minimum number of programmed keys required. This PID reads 2 or 4, dependent on the vehicle build. |
| PCM_ID | PCM ID status stored | Indicates if there is a PCM identification currently stored in the BCM. Must read stored for the vehicle to start. |
| PCM_VERIFY | PCM verify OK | Indicates if the PCM identification and the BCM identification match. Must read yes for the vehicle to start. |
| START_ENABLD | Vehicle enable status | Indicates if the PATS allows the engine to start. Must read enabled for the engine to start. |
