Yes. The ECM may not work but the physical condition must be in salvageable condition.
No, we do not load the software, just replace components that will not allow the ecm to work. We do have software to restart the ECM in a boot loader and allow the ECM to function in a test enviroment.
At this time we only repair ECM's on Semi Trucks and Heavy Machinery including Cummins, Navistar, Caterpillar, Paccar, Volvo, Mack, Isuzu, Perkins, Deutz, Komatsu, Kubota, John Deere, Mitsubishi, and others.
