P0D5EBattery Charger Hybrid/EV System Discharge Time Too Long

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
How the car detects it
P0D5E means the high-voltage side of the charger did not drop to a safe level in time after it was disconnected. GM's 2011 Volt charger module fails the test if 60 V or more remain 1.5 s after the discharge command, or 6.75 s after a confirmed communication loss with the hybrid controller; a backup routine then checks for battery current that would reveal a stuck contactor. The 2016 Volt allows 4 s after the contactors open, the 2019 Volt also 4 s against 58 V and adds a case for a failed voltage sensor combined with a stuck negative contactor. All are Type A with immediate MIL. A patent for on-board charger discharge circuits cites roughly 60 V as the safety limit. The opposite fault is P0D5D.
What you may notice
  • MIL on (GM)
  • Charging blocked after the fault
  • Further high-voltage codes such as contactor faults may be stored
Likely causes
  • LikelyActive discharge circuit of the charger not working
  • PossibleHigh-voltage contactor stuck closed keeps the bus energised
  • RareLost communication between charger and hybrid controller
  • RareCharger voltage sensor reads falsely high
