Okay, did a little quick searching and looks like O'Reilly's has my ECM for just over $400, seems well worth the difference in price. I'll be going this route in the next week or two, I'll update the thread and let you all know how it works out for me...

 

A p0601 code is definately an internal Dodge ecm failure. Of all the codes the p0601 should be taken as the most serious because if you don't get a new ecm soon you'll be stranded on the side of the road one day. This happened to me but luckily I was able to find a local shop to rebuild my ecm part number 3942336 for 575.00. They are located in the Detroit area and they have a website http://www.ecmoutlet.com Hopefully this helps any of you guys with a bad cummins ecu.

 

i have an 01 1500 5.2l my truck started making a weird popping sound if im at a set speed then try to accelerate it does it then i lose power but when i floor it,it stops.it has been doing it more and more everytime i drive it so far i changed the fuel pump,plugs and wires,tps,cleaned throttle body, checked pressure in fuel rail cleaned injectors,so i bought a obd2 and the code p0601 came up i know it is my pcm but now my trany is shifting late from first to second and if im on the highway and i give it enough gas to down shift it goes to first and red lines could all of this be coming from the pcm.need help please

 

Need to replace the PCM first, to eliminate that as a possibility.

 

just orderd one matching it to my vin milage and pcm numbers will be here in 4-7 days let you know how i make out and thank you for replying

 

Where did you purchase it from? And yes, please let us know the results.

 

i got it from auto computer exchange for 200 shipped lifetime warranty complety tested and ready to run

 

Uhh, Isn't that the one place that everyone on here suggests NOT to get it from? The search function does work once in a while you know.
