P0364DC/AC Converter Control Module Control Circuit Range/Performance

  • Generic OBD-II code · Powertrain
How the car detects it
P0364 reports that the control circuit between the engine module and the control module of a DC/AC converter (inverter) behaves implausibly – the command or enable line is present but its signal does not fit what the engine module expects. The code is a late assignment in the P03xx block; the other DC/AC converter codes sit in the P2DAx range (P2DA8–P2DAB). Ford uses it on the 2021 F-150. On the 3.5 L PowerBoost hybrid, whose DC/AC converter module A feeds the Pro Power Onboard sockets, bulletin 21-2229 links P0364 in the PCM to a disabled Pro Power Onboard and a 'Pro Power Onboard Service Required' message; the cause was software parameters in the inverter and the PCM, fixed by reprogramming both. Bulletin 21-2087 lists P0364 among the codes that 3.5 L EcoBoost trucks built up to 2 March 2021 stored with the MIL on, cured by a PCM update alone. Without such a bulletin, check the enable and command wiring between PCM and inverter and the software levels of both modules.
