Questions:
1. If car runs fine, can we assume the ECU is good?
2. CAN communication is between which computers?
3. OPV is new, battery good, what else I can check?
The codes you read "point" toward a deteriorating wiring harness and/or a crumbling ETA wire harness. Need to inspect it to be sure.

You need to actually determine if the w-h has been replaced; if not, it MUST be done before anything else, since it does cause the #17 and cruise control to APPEAR bad when they're not.
