No generator codes listed. The two smaller terminals at the generator are field terminals. The white wire with dark blue tracer is source voltage, engine running, shouldn't be less than 10 volts.
If you want to word it this way, the voltage regulator circuity is in the pcm. The second smaller wire, the computer switches that circuit on and off to control charging. Could be wiring issues, could be computer issue.
Make sure the battery has a full charge. A couple of the codes, you listed, I don't know what they are?
