P0D6FA/C Compressor Motor Current High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Needs a drive cycle to confirm a fix
How the car detects it
P0D6F flags excessive current drawn by the electric A/C compressor on its high-voltage DC link while the motor is running. GM's first-generation Volt (2011–2015) and the 2016 Cadillac ELR set it when the DC link current exceeds 27 A in 30 of 60 samples taken every 50 ms with a compressor speed request above zero; it is Type B, MIL after two trips. A separate maker code, P1EC9, catches momentary peaks above 60 A. The second-generation Volt tables no longer list P0D6F. High current points to a mechanically binding or liquid-slugging compressor, a shorted motor winding or a failing power stage; overcharged refrigerant or very high head pressure can also raise the load. Phase-specific current faults are P0D7A to P0D7F.
What you may notice
