What P0D5E means
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.
P0D5E at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D5E
- MIL on (GM)
- Charging blocked after the fault
- Further high-voltage codes such as contactor faults may be stored
Common causes of P0D5E
- Most likelyActive discharge circuit of the charger not working
- PossibleHigh-voltage contactor stuck closed keeps the bus energised
- Less likelyLost communication between charger and hybrid controller
- Less likelyCharger voltage sensor reads falsely high
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D5E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 5E | The exact fault in that area. |
What to do next
- Note P0D5E and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D5E
What does P0D5E mean?
P0D5E means "Battery Charger Hybrid/EV System Discharge Time Too Long". P0D5E means the high-voltage side of the charger did not drop to a safe level in time after it was disconnected. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D5E?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0D5E fail an emissions test?
P0D5E is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0D5E to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0D5E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
