B012E code meaning
DC/AC Converter A High Voltage Power Outlet Control Module "C"
What B012E means
B012E concerns outlet control module C. GM's name for the part is accessory AC and DC power control module: in program N222385490, 2023 Silverado and Sierra 1500 built from September 2022 without a working inverter, because of the chip shortage, received this module, a fuse and BCM reprogramming, with separate inverters for 110 V (RPO KI4) and 230 V (KI5). Ford's patent US11043801B2 describes the control side: relays switching each socket, run timers and power limits, all managed by the DCACA controller. Whether module C is a third unit or another function is not published, and no manufacturer documents B012E. Typical causes are supply, ground, network faults or missing configuration after replacement.

Symptoms of B012E
- Power outlets in cab and bed inoperative
- Outlet functions missing from the display menu
- Module handles 120/240 V AC from a high-voltage source; work only with the system de-energised
Common causes of B012E
- Most likelyModule C or BCM not configured or programmed after installation or replacement
- PossibleFuse, supply or ground of module C faulty
- Less likelyModule C internally defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note B012E 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.
