P0D0EBattery Charging System Negative Contactor A Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D0E is the general circuit code for negative contactor A of the charging system, which connects the minus side of the charging path – from DC inlet or on-board charger – to the traction battery. It is used when the module sees an electrical fault on that contactor that it does not classify more precisely. No manufacturer documents P0D0E publicly. A GM patent on battery disconnect diagnosis shows separate contactor pairs for fast and slow charging and judges each by its coil current, and CARB requires plug-in vehicles to monitor charging components. Welding or failure to close on the negative side are P0D0F/P0D10, driver faults P0D11–P0D14, the positive side P0D07, the main pack contactors P0AA3 ff. In most cases only charging is affected.
