B012DDC/AC Converter A High Voltage Power Outlet Control Module "B"

  • Generic OBD-II code · Body
How the car detects it
B012D addresses outlet control module B. A converter for household sockets interacts with the rest of the vehicle both electrically and by radio. Ford's TSB 23-2218 for 2021–2023 F-150 with the DCACA inverter shows radio-frequency interference from the inverter upsetting the tyre pressure system, so the BCM stores B124D and lights the TPMS lamp; the procedure confirms the inverter as source and suppresses the interference. Toyota Industries' patent US10050558B2 describes a 12 V-fed inverter that only runs between about 11 and 16 V and shuts down on overvoltage or when its power devices overheat. Which unit module B is remains unpublished; no maker documents B012D. Supply, ground and data lines come before a new module.
What you may notice
  • Outlets switch off or are unavailable
  • Side effects on radio-based systems such as tyre pressure monitoring
  • Module handles 120/240 V AC from a high-voltage source; work only with the system de-energised
Likely causes
  • LikelySupply voltage outside the permitted window, weak 12 V battery or poor ground
  • PossibleModule B overheating, blocked air path or cooling fan failed
  • RareModule B internally defective or emitting interference
