PATS Parameter Identifications (PIDs)
In conjunction with Diagnostic Trouble Codes (DTCs), the PATS Parameter Identification (PIDs) are a useful tool when diagnosing the PATS concerns.
BCM PID CHART
| Acronym | Name | Description |
|---|---|---|
| KEYS_PROGMD | PATS Number of Ignition Key Codes Supported | Number of keys currently programmed into the BCM. |
| MIN_KEYS_RQD | Minimum number of keys required | Minimum number of programmed keys required. This PID always reads 2. |
| PCM_ID | PCM ID Status Stored | Indicates if there is a PCM identification currently stored in the BCM. Must read stored for the engine to start. |
| PCM_VERIFY | PCM Verify OK | Indicates if the module identification check between the BCM and the PCM passes. Must read yes for the engine to start. |
| START_ENABLD | Vehicle Enable Status | Indicates if the PATS allows the engine to start. Must read enabled for the engine to start. |
