P2CFC A/C Clutch Control Circuit

P2CFC is the general fault of the output that powers the compressor clutch coil directly, unlike P0645, which covers a clutch relay. Ford is the documented user and runs it in a body module, not the PCM. Special service messages 50811 and 51380 list P2CFC, often with P0645 and P2CFD, in the HVAC module of 2020–2023 Explorer and Aviator; the cause was spread or pushed-out terminals at body control module C, so pins are checked before that module is replaced. SSM 53061 reports P2CFC in the same module on F-150 trucks of 2021–2024 and Super Duty models of 2023–2024 and says voltage left on the clutch field coil while uncommanded is no reason for a new module. Ford's OBD summaries omit the code. The compressor stays off and only warm air comes out.

Likely causes

Spread or pushed-out terminals at the body control module connector
Open or burnt clutch field coil
Damaged wire or connector between module and compressor
Faulty clutch output in the controlling module

Symptoms

  • A/C blows only warm air
  • Compressor clutch does not engage
  • Code stored in the HVAC or body control module, usually without engine lamp
