MBS_K Expansion node is not starting
- Check the fuse, connectors, and cable harness. - Check the indicators on the faulty node: - No LED is powered or flashing. (Dead expansion node) - Orange LED triple flashing (Application is not executing): Missing or damaged application software: Update the application software , - Orange LED blinking every second (Application is running): No error - Yellow LED is not active: No CAN traffic; the node has no connection to MBS (Master) : Check the CAN bus, connectors, and cable harness. - Yellow active (Shimmering ): CAN communication is OK. No Error - Yellow steady : ECU detects CAN bus physical problems, trying to recover. : Check the connections or damaged wiring.

System reaction
Functions dependent on MBS_K are missing or degraded. An amber warning will be shown in the ICL.
Diagnostic depth
No communication has been received from the MBS_K expansion node since startup.
The fault is most likely in the MBS_K unit or the violet CAN bus • During production: - Faulty installation of the expansion node. - Incorrectly connected expansion node. - Dead expansion node. • Bus is in Service (After production) - Dead expansion unit
