If MIL is indicated, does MDS operate?
Have had a recurring MIL code(twice) on my wife's 2005 5.7 Hemi. Have reset the PCM twice by disconecting the neg. ground cable. Just purchased a Scan Code reader to further isolate the issue. Have been a Jeep owner for many years and all of the "MIL" previous problems(On other Jeeps) have been related to the common evap. issues related to the gas cap. In either case, does the MDS not operate if the MIL light is on? Thanks for any inputs.

I believe most DTCs will prevent the MDS from operating.
