    check e-mail
    check voltages on ECM connector.

    DR - ignition sw/ power, if ECM is OK it actuates power relay.

    No batt fuse with D12A..... it is powered from cabin, really Volvo never use unswitched (battery) power on engine ECMs. If you see fuse to ECM in battery box - truck got CAT, DD ore Cummins engine.

    No battery power on engine ECM is Vovo feature
