I just bought my used 2012 RAM 2500 Diesel Long Bed Crew Cab 4x4 a few months back and am still learning some of the wonderful features that the totally computerized system provide for me (sarcasm intended)...

Sooo... The other day at work I started to stick the truck in some loose sand. I still have street tires on it so I stopped digging holes, dropped the transfer case into 4x4 Low and started to ease out the way I came in... The "4x4 Low" light went out and a big honkin' "SERV 4x4" lit up... OK, so I then snatch the transfer case back into 4x4 High and extracted myself from the dirt... The 4x4 seems to be working OK in High but faults out every time I put it into Low.

The truck just rolled 150,000 last week and is due for service. I don't have a service record for the truck so am planning on just having the dealer do a baseline "service everything" kinda job. Is this "SERV 4X4" just because service is due or is this something I should take out another bank loan after I have the dealer look at it??

Thanks everyone for making this a really great place to see out help!

Probably a bad transfer case motor.. or faulty solenoid.. either way it will need to be replaced

Easy to do.. 200$ or so in parts

Which transfer case do you have?
Do you have the dial shifter, or lever on the floor?

Hi Muddy,

Sorry, have been offline for a few months... I have the floor shifter and the NV271 transfer case. I haven't had a chance to revisit this problem yet but am getting ready to spend some quality time with my truck and shop.

Thanks!
