    I have Peterbilt truck with Cummins ISC tried to start it but no luck, active fault codes as below and I checked all connections for the 6 cylinders harness and all are good as per specs
    I know it could be the ECM itself but I just want to make sure before buying a new ECM and find the same issue exist

    Please advise if there is any more troubleshooting can be done and how to make sure if ECM damaged
