Hi I recently posted what was wrong with my dads truck. The ECM was bad from what I was told. My question is if nothing is burnt in the circuits why could they not reflash it. Also where is the powertrain relay located in the truck and what does it do. If I get a remanufactured ECM does it have to be flashed. Thanks. I like to learn and find out what stuff does.
have the same problem?
