"Charging system circuit not responding to control signal".
I've never run into that code, but I'd start by measuring battery voltage while the engine is running. It must be between 13.75 and 14.75 volts. If it's low, measure the voltages on the two small wires on the back of the alternator. That must be done while the engine is running.
