A communication error has occurred between modules within the ECM system. This indicates a problem with the data link or signal integrity between internal components.

1. 1

   Inspect all internal communication cables and connectors within the ECM for secure connections.

2. 2

   Check for electromagnetic interference that could disrupt communication signals.

3. 3

   Verify the status LEDs on individual ECM modules for further diagnostic information.
