B012A code meaning
DC/AC Converter A High Voltage Power Outlet "D" Circuit/Open
What B012A means
B012A concerns outlet D. Sockets in a pickup bed live in a harsher place than those in the cab: dust, rain, washing and cords left plugged in. Ford's customer satisfaction program 21B52 shows how tightly bed outlets are tied into the vehicle: on certain 2021 F-150 Raptor trucks with Pro Power Onboard, a bed outlet cover standing open more than about 17 degrees kept the truck from shifting out of Park until the PCM was reprogrammed. In Ford's patent US11043801B2 the bed outlet carries several sockets, each with its own switch and protection, and a second outlet sits in the cab. Whether D is a bed socket is not published, and no manufacturer documents B012A. Moisture in the socket or its connector is a likely cause.

Symptoms of B012A
- Socket D without power, other sockets may work
- Message that onboard power or an outlet is unavailable
- Outlet circuits carry 120/240 V AC from a high-voltage source; work only with the system de-energised
Common causes of B012A
- Most likelyWater or corrosion in socket D or its connector, typical for exterior or bed outlets
- PossibleHarness to outlet D chafed or crushed in the body or bed

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B012A means

| 2A | The exact fault in that area. |
What to do next
- Note B012A and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
