Well, I own this truck, I tagged it Phat ***.

[rambo]

It's a 01 3500 quad high premium 2wd -7 HO 6spd I bought 2 yrs back. My first diesel, Ram, it's has some miles but no damage or rust, could use a new dash and some paint.  When i picked it up the cruise was Inop. and the trip computer read no CCD but the gauge cluster works fine. Is the CCD bus broken up into diff. sections?32  If both read outs are on the same bus shouldn't they both have No CCD?  The Stereo has a aftermarket deck in its place and the steering wheel  collum radio controls are disconnected. Can a poor radio install cause a bus failure?   It has a strong engine but it's 235 hp,  not the -7 HO it originally had, this is probably my cruz issue , it also pulls allott of value away that  I can't afford to lose  So extended plan is to r&r the engine, I will need a 01 5.9l T.D. 24v -7 HO,  Can i use a dealer to confirm the original P/N for the ECM using the VIN?   which i'm sure was changed,  Was a PCM change required also to do this swap?  And any tips will be very appreciated.    Thank You
