That's the only code in the power train or anything I can find related in the least (has a loss of comunication with the radio code in some module I came across). I don't get why the heck they had to go back to unlocking the front hub in these bass tirds, or even electric shift for that matter, the manual shift in my dakotas was way faster and easier to engage than this electronical crap. My 4x4 daks barely got any worse MPG than my 2wds and I always keep very meticulous track of what they do. I followed the factory diagnostic chart very carefully about 10 times and it says the solenoid is bad, both the one off this truck and my personal truck work on my truck and neither works on this one. Looking at the wiring diagram none of the wires for this circuit go to the t-case motor, they all go direct to the locker thingy.
