I got a p0601 code the other day, when my battery died. So i went and bought a new battery. Reset the ecm a few times and drove it around for a few hrs each time but the p0601 just keeps coming back on. I was wondering if all none security code ecu 4.7 auto would work in my dakota. My truck is a 2001 dakota 4.7 auto and i have a guy that says he has a 2001 dakota 4.7 auto but it's from a 4x4 and my truck 2 wheel drive will it still work if it's a no security key ecm too. ? If not will the Durango or ram or jeep 4.7 auto all interchangeable or does it have to be a dakota with the same year make and model.?
