Common on the 05's. Go see your dealer, there is a TSB out, needs a re-flash to go away once and for all.

Re: Service 4WD System Message

But what exactly does the reflash do? I mean is this just some sort of weird glitch that this new software fixes? I mean it has to be doing it for some reason right??!!

Re: Service 4WD System Message

I was told that there is a programming error in a "timing" in the 4wd system , the same message kept popping up on my 06 right after I got it. The dealer did the TSB (re-flashed it) and i haven't seen it since. and they do it for FREE!

Re: Service 4WD System Message

Mine's going in the shop tomorrow for some other things...I'm going to see if they can do this too....Doubt they'll do it for free but I'm sure going to ask.

Re: Service 4WD System Message

I may have to go to the dealer and get mine flashed. This pops up ALL the time for me and its pretty annoying when I'm driving @ interstate speeds and it BINGS really loud...

Re: Service 4WD System Message

my 06 used to do it alot and i had the dealer flash the computer. went away for probably 3 years and is now coming back on intermittently. it will come on if i drive too fast over railroad tracks or if i'm turning into a drive that has a steeper grade than the road. it is annoying. it's back off everytime i restart the jeep though.

Re: Service 4WD System Message

Took mine in today for other stuff and this too. $93 to do the TSB on it so it's not free. We'll see if it fixes the problem.

Re: Service 4WD System Message

Dealer called and said T-case module is bad? Anyone know if this is an easy fix to do it yourself?
