Display DTC (Diagnostic Trouble Codes)
DTC codes can be read by clicking on the Diagnostics tab at the bottom of the monitor page. The source of
the DTC stream can be set manually for the MEFI ECM or the S3000 ECM, or left in the default All position for auto
detection of the DTC codes from either MEFI or the S3000 ECM. Codes that can be viewed are set in two catego-
ries, active and historic. Active codes are codes that are set and the fault that is causing the code to set is
constant. Historic codes are codes that have set in the past, but the fault that caused them has been corrected
such as with an intermittent problem. This function is selectable by choosing the Active or Historic, as shown in
the above image. Codes can be cleared by clicking the Clear box. The DTC set code list may also be saved by
clicking the Save box shown above. The file will be saved in a convenient HTML file compatible with Windows In-
ternet Explorer and will provide a browse function to save the file to a location of choice for the service technician.
