Fault Family System: Powertrain (P-Codes) 40 SAE Codes

Battery Charger AC Input Circuit

Diagnostic & Technical Explanation
Code P0D27 sets when the onboard charger's AC input rectifier stage reports a voltage, current, or frequency from the EVSE supply that falls outside the expected range for the charge session in progress. The most common physical causes are a corroded or loose connection at the charge inlet's AC pins, a marginal or overloaded EVSE/wall-circuit supply upstream of the vehicle, and a failed input rectifier or PFC stage inside the charger itself. Because the fault originates on the AC (mains) side before any HV conversion happens, testing the inlet and EVSE supply should come before suspecting the charger's internal HV-side hardware.

These 40 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 40 times.
