P0D0A: Battery Charging System Positive Contactor A Control Circuit/Open

Powertrain Battery Charging and Cell Balancing Emissions related

What to do

As P0D07. These are the charging contactors rather than the pack's main pair, so a car with this fault may drive perfectly and simply refuse to charge. High-voltage work throughout.

What this code means

The circuit commanding the positive charging contactor is open. The charging contactors, and how they differ from the pack's main pair, are at P0D07; why both poles are switched is at P0D0E.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
