Q: What does code P2DCF mean?

Control Pilot Charging Switch B Range/Performance. P2DCF indicates that the control pilot circuit's charging switch B is reporting a range or performance fault, meaning the voltage or signal the module expects from that switch falls outside its valid operating window. The computer has detected an implausible signal from the switch that controls the pilot line during charging, so it cannot confirm the switch is opening and closing correctly.
