PATS Parameter Identifications (PIDs)
In conjunction with Diagnostic Trouble Codes (DTCs), the PATS Parameter Identifications (PIDs) are a useful tool when diagnosing PATS concerns.
BCM Parameter Identification (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 Parameter Identification (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 PCM identification received by the BCM matches the PCM identification stored in the BCM memory. 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. |
PCM Parameter Identification (PID) Chart
| Acronym | Name | Description |
|---|---|---|
| PCMID | PCM ID Status Stored | Indicates if there is a BCM identification currently stored in the PCM. Must read stored for the vehicle to be driven. |
| PATSENABL | Vehicle Enable Status | Indicates if PATS allows the vehicle to be driven. Must read enabled for the engine to start. |
