P0D5DBattery Charger Hybrid/EV System Discharge Time Too Short

  • Generic OBD-II code · Powertrain
How the car detects it
P0D5D concerns the active discharge of the charger's high-voltage side after charging ends: the stored voltage collapses faster than the circuit design allows. No manufacturer documents P0D5D publicly; GM's Volt only publishes the opposite case P0D5E. Patent literature explains why a fast drop is suspicious too: a German application on high-voltage diagnostics describes detecting a discharge path that is permanently switched on, and a quick decay can equally point to lost capacitance or a faulty voltage reading. Safety is not at risk, since the voltage does fall below the touch-safe level, but the electronics may be degraded. CARB requires detection of charger faults that disable or limit charging. Charging may be refused until the fault is repaired.
What you may notice
  • Charging system warning after the end of charging
  • Next charging session may not start
  • No noticeable effect while driving
Likely causes
  • PossibleDischarge switch inside the charger stuck closed
  • PossibleLink capacitor lost capacitance
  • PossibleCharger voltage measurement reads falsely low
