"SERVICE 4WD SYSTEM"
Hey Guys, would anyone know how to fix "Service 4WD system" the sign
constantly coming up and 4WD is not shifting.
Yes. You need to take it to a Dodge dealership. They will reprogram the TCU with a software update. It only takes a few minutes. Check first though. There was a recall for this problem and you might get them to perform this service free. It's a proprietary software and not available to the general public or a garage.
