P0D07Battery Charging System Positive Contactor A Circuit

  • Generic OBD-II code · Powertrain
How the car detects it
P0D07 is the general circuit code for positive contactor A of the charging system, the switch that joins the plus side of a charging path to the traction battery. Depending on the design this path comes from the DC fast-charge inlet or from the on-board charger; the Chevrolet Volt, for instance, places charging contactors between charger and pack. The code stands for an electrical fault in that contactor branch which fits no more specific case. No manufacturer documents P0D07 publicly; a GM patent describes judging such contactors by their coil current, and CARB requires plug-in vehicles to monitor charging components. Welded or non-closing contacts are P0D08/P0D09, driver faults P0D0A–P0D0D, the main pack contactors P0AA0 ff. Usually charging is blocked while driving still works.
