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.

Likely causes

Outdated or corrupted module software; reprogramming per maker bulletin
Power, ground or network connection of module A faulty
Module A internally defective, e.g. cooling fan or power stage

Symptoms

  • 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
