P2CC6Generator Inverter Power Supply B Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2CC6 means supply B of the generator inverter is present but below its permitted level. A weak gate driver feed is dangerous for the power stage: transistors that are not driven fully on run in a lossy partial state and heat up quickly, so the inverter typically blocks the generator. No manufacturer documents P2CC6 publicly. Ford's summary for its 2019 power-split hybrids places the related supply A code P0E10 among the generator-side gate signal faults together with P0BCE and P0BCF, which suggests the same home for supply B. Causes range from a failing internal regulator to low 12 V input during start-up or a corroded ground. CARB requires circuit monitoring for hybrid parts. Siblings: P2CC5 (open) and P2CC7 (high).
- What you may notice
- Hybrid system warning light and MIL on
- Generator limited or switched off, reduced hybrid performance
- Likely causes
- PossibleInternal regulator of supply B delivering too little voltage
- PossibleLow 12 V input to the inverter, e.g. weak auxiliary battery
- RareCorroded ground or connector of the inverter
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
