| Broadcast Message | Originating Module | Message Purpose |

| Passive entry target data | BCM | This is a response to the BCM request for the RFA module ID and IA key data. The request is part of the PATS process of the BCM to check the RFA module ID with the ID stored in the BCM. If the RFA module ID and IA key data response is correct, the engine is allowed to start |
| Door ajar status | BCM | The RFA module uses this information to determine if it should search the interior of the vehicle for an IA key. It searches for an IA key if any door or luggage compartment lid is opened and then closed. |
