I have a 2010 Ram with a 5.7 Hemi. Today The check engine light came on and the MDS won't engage. I was wondering if there was a way to check the fault codes like there is in older models by cycling the key.

Thanks

Should be the same key trick, turn the key from off to on like 3 times I believe?

Yes, 5/20. I tried cycling the key 3 times earlier today. I will try again in the morning.

Thanks

Tried it again, but couldn't get it to work. I tried it at different speeds but nothing happened. If it does work on the 4th gen, what's the trick?
