B012C code meaning
DC/AC Converter A High Voltage Power Outlet Control Module "A"
What B012C means
B012C names power outlet control module A of converter A without a fault type, so the module itself is under suspicion rather than one socket. Ford calls its unit DCACA; on the F-150 with the 2.0 kW system it sits in the cab under the left rear seat. Ford's SSM 50167 traced a loud fan on early 2021 builds to DCACA software, and SSM 52213 for 2022–2023 F-150 and 2023 Super Duty a dealer-service message with P0A93:96 stored in the DCACA; both were cured by reprogramming. Neither bulletin mentions B012C, and no manufacturer documents the code; it is open whether module A means the inverter itself or a separate outlet controller. Usually all outlets of the converter are unavailable.
B012C at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B012C
- Onboard power unavailable or service message in the centre display
- Unusual fan noise from the module's location
- Module handles 120/240 V AC from a high-voltage source; work only with the system de-energised
Common causes of B012C
- Most likelyOutdated or corrupted module software; reprogramming per maker bulletin
- PossiblePower, ground or network connection of module A faulty
- Less likelyModule A internally defective, e.g. cooling fan or power stage
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B012C means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2C | The exact fault in that area. |
What to do next
- Note B012C 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.
