CLAAS 7F07h – BDG: No Communication from WLP Module

Issue description

The Dashboard module (DBD A101) has not received a message from the Working Light Panel module (WLP A104) for more than five seconds. This indicates a CAN bus communication timeout error, suggesting an interruption in the data link between the two components. The system is designed to return to normal operation once communication is re-established.
