Q: What does code P2DAA mean?

DC/AC Converter Control Module A Switch B Circuit. P2DAA indicates that the control module for the DC-to-AC converter (often an inverter for an accessory power outlet) has detected an abnormal condition in the circuit for switch B, which is one of the internal or external switching components that manage power flow. The computer sets this code when the voltage or current on that switch circuit falls outside the expected range during operation, pointing to a fault in the switch itself, its wiring, or the control module's ability to drive it.
