Well here we go again, just traded my 02 quad 4x4, HO 6spd for a brand spankin new 3500 drw 325/610 auto quad cab, and with just 300 miles on it , I watched a tow truck take it back to the dealership. I did the 3 key turn thing before it left and got a p0606, any ideas ? Dealer said the enitre computor needs replaced. I haven't done a thing to this vehicle as I learned my lesson with the last truck after installing a multitude of banks stuff. Heck I have not even washed it yet. Any Ideas with the code and has anyone else had their brand new truck go dead ? Causes , or Ideas ?

 

P0606 = ECM Failure

Sorry to hear that with only 300 miles.
