P2D62Battery Charging System Negative Contactor C Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D62 is the collective electrical code covering minus contactor C, which connects the return conductor of the third charging path to the traction battery. Neither the code nor the meaning of C is documented by any manufacturer. Separate switches in both poles are common on charging paths because only then can the inlet be fully isolated, and diagnosing the pair needs one pole held closed while the other is tested: a Hyundai quick-charge patent checks the plus relay first and then the minus relay against the voltage at the charging inlet, so a minus-side fault is pinned down separately. Under CARB, a plug-in hybrid must flag charging faults that disable or limit charging. Welded and non-closing cases are P2D63/P2D64, driver faults P2D65–P2D68, the plus side P2D5B. The charging mode via C is typically disabled.
