Thanks goes to Sprintguy Carl.
vicCan I get everyone on the this forum straight.. Mercedes Benz diagnostic aid ie scanner is called a SDS 2 different systems.
T1N = DAS (Diagnostic Assistants System) used from 2002-2013.
2014 to present MB system is SDS [Mercedes-Benz Star Diagnosis System] running Xentry program.
Now Chrysler used 2002-2006 DRBIII [Diagnostic Readout Box 3rd Gen] ... 2007-2009 Chrysler used the Starscan, Star mobile etc.
Just trying to get the terminology correct.
Make sure all powers are present at the controller both battery circuits and ignition circuit, also make sure the TCM is turning the relay on .. there should be more than 1 ground If I remember correctly.
