Engine Diagnostics
When choosing this selection, the display will query the engine(s) ECU and provide feedback on any diagnostic codes that have been activated and stored in the ECU for service needs.
The Engine Diagnostics option displays faults based on engine or transmission source. A description of the fault as well as the suggested action for correction is provided for each fault occurrence.
The following is a list of field definitions contained on the ENGINE DIAGNOSTICS screen:
•Source – identifies the component having the fault; engine 1, 2, or auxiliary.
•Status – indicates whether the fault has been corrected.
•SPN
If not translated into text by the display, see the engine manufacturer's literature for the definition of the SPN number.
