Diagnostic Trouble Codes
The controller has a DTC feature that, when enabled, allows the controller to receive currently active
DTCs (DM1) messages and display then on the screen as well as optionally store them to the Event
History. The controller can also receive previously active (DM2) messages and display them on
command. DM2 messages are intended for technician troubleshooting and are not stored to Event
History.

DTC Display
This setting enables or disables active fault messages (DM1) monitoring. When the DTC DISPLAY
feature is enabled the controller can receive active faults in the RUNNING, OFF and AUTO modes on the
J1939 bus. Any new received active faults will trigger a message "NEW ACTIVE DTC" and the user can
read the message on the controller front panel display. This new message will also be stored into the
controller’s event log if this feature was enabled.
Active Log DTC
The setting enables/disables the storing of active faults (DM1) in controller Event Log. The Event Log
reserves 30 storage locations for DM1 messages.
Read Stored DTC
The setting enables/disables the ability to request stored fault codes from the ECM (DM2). When this
setting is enabled the controller will allow manually triggered requests of stored faults from the ECM’s
memory (DM2).
