Engagement and Monitor Unit Display Messages-EH Controls

The engagement and monitor unit (EMU) automatically displays a message for specific machine situations and certain diagnostic trouble codes (DTCs). Depending on machine situation or if a DTC is initially active, a message displays on the EMU until the situation changes, the DTC is resolved, or the operator presses any button on the EMU.

If multiple display messages are generated, the one with the highest EMU priority displays. Pressing any button on the EMU closes the displayed message, allowing the next message to display in order of EMU importance until all generated messages have been displayed.
