I have a 2014 T590 showing me a code M6604. Saying no power to the ECU
I have switched all the relays found no change, fuses are all good but did notice I have no power going to the ECM fuse after putting the meter on the leads for the fuse. I traced what i could find for these wires and I can find any issues. Not sure what my next step would be. Any help or suggestions ?
