60 series detroit, 12.7 435/470HP vin# XXXXX This code I'm getting is off the dash readout on the truck.
Thanks for the info.
This fault is normally for a faulty ecm. There are no circuit breakers for the ecm.I would make sure there is nothing between the ecm and the block shorting it out. Also check the mounting isolators at the ecm and make sure they are not allowing the ecm to touch the block. The only fuse for the power harness is in the battery box or right outside of it. Sometimes there are 2 fuses. You should have a 5 amp ignition fuse in the fuse panel. I would next unplug the power harness from the ecm and check it. It is the top plug on starter side of ecm. You should have 12 volts A and C pins and a good ground at the other 3 pins. I would also inspect the power harness all the way back to the batteries for rubbed spot. I have seen lots of power harness issues. I hope this helps you out. If you have anymore questions, just ask.
