the 4 wire power only bench test of the ECU , is conclusive.
5vdc dead ECU is dead.
ic17 bad, nobody on earth sells this, so super hard to repair, when blown, or pin 1 is dead IC 17, means IC7 is bad.
if the Cel lamp is dead (will not flash DTC codes at all, IC7 or Q105 are bad.
that is far as I can peel this onion, lacking more tests.
