Who knows about FCCC "MMDC" and its issues?
Gents, I've searched and read many issues regarding the old "VDC" units and the newer MMDC units. I'm thinking I may have developed an MMDC issue. Here's the scenario. We're presently on vacation and...

One of the things I learned yesterday was, there's two resistors in the J1939 data link. One is accessed just down line from the rear diagnostic port, just above the radiator. The other, is located INSIDE the MMDC.
Now if this isn't one of the most asinine things done in auto technology, I don't know what is. You see, that little, "$.50" resistor, is INSIDE a $400.00 computer. So, when that little fifty cent resistor goes bad, you get to spend $400.00 and, pay to have it replaced when, I can have that MMDC out of my coach in right at 2 minutes.
So they put one of the "end of line" resistors inside of a component? Wow, that is one that I haven't seen. I agree.. that is dumb!
