  • Generic OBD-II code · Body
How the car detects it
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.
