P0D09 code meaning
Battery Charging System Positive Contactor A Stuck Open
Powertrain system Generic code P0Dxx codes Check engine light
What P0D09 means
P0D09 is set when positive charging contactor A fails to close: after the command the expected voltage never shows up on the charger side. GM documents the check for the Chevrolet Volt (VICM 2016, HPC2 2019): during charger precharge, with charging and precharge contactors on and the negative main contactor still off, a charger voltage under 10 V ends the test; 2016 needs 8 failing samples out of 9, 2019 waits for at least 0.7 s of precharge. Both are Type A, MIL after one trip. Kia lists P0D0972 for the 2023 Niro EV (bulletin 298, ICCU replacement), Stellantis P0D09 for Wagoneer S and Charger Daytona (BPCM update), GM preliminary PIT6083 for the 2024 Lyriq after very long charging. Charging then stops or never starts; the welded case is P0D08.
P0D09 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D09
- Charging does not start or ends shortly after plugging in
- Malfunction indicator lamp after one trip (GM Type A)
- Charging or high-voltage warning in the cluster
Common causes of P0D09
- Most likelyContactor mechanically failing to close or burnt contacts
- PossibleFault in the on-board charger or integrated charging unit (Kia ICCU bulletin)
- PossibleControl software needing an update (Stellantis, GM Lyriq)
- Less likelyMissing coil supply because of a wiring or fuse fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D09 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 09 | The exact fault in that area. |
What to do next
- Note P0D09 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 P0D09
What does P0D09 mean?
P0D09 means "Battery Charging System Positive Contactor A Stuck Open". P0D09 is set when positive charging contactor A fails to close: after the command the expected voltage never shows up on the charger side. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D09?
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 P0D09 fail an emissions test?
P0D09 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 P0D09 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0D09 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
