Ethridge, TN | Have had this same problem with ECM wires, also Frieghtliners here. Both the positive and ground for the ECM are in a separate harness, and feed from the battery connections. On the Freightliner, there is also a spot in the harness, where the 12v+ splits, and I've had that connection corrode, will also keep the truck from firing. Then, also had one that just up and acted like you shut it off, going down the road, that one ended up being the ECM died. | |
