Serv 4wd

[Andrew09HEMI]

So I recently been having this pop up on start up, stays for about 4-5 secs then is gone. No stored codes, no messages no other lights. I had the fluids changed on the driveline not but maybe 7k miles ago at the dealer. It makes me wonder if they actually did a service though cause they couldnt even diagnose a rear power window right! Anyone else had this before? 4wd does engage and feels alright, minor vibration very minor from level and CV angles..

Also, an unrelated issue is the MDS. I know many of you deactivate via tuner which I can do and I do not use it when driving around town, but on the highway it literally delays for 3 secs sometimes longer when I go to accelerate. It has the right oil, Amsoil 5w20 synthetic and Wix filter that I just did so its not that. I know some people have had issue with the hemi's cam gears which controls the MDS functionality.. Thoughts?

What are you using to check codes?

Mine comes on every time I start the truck. Dealer told me it's the truck running a system check, and not to worry unless it stays on and 4wd won't engage.

No clue about the MDS.

Didn't catch that he said it only goes on for a few seconds then turns off. All the warning lights come on for a few seconds when the truck starts, it's basically a bulb check.
