What P0D08 means
P0D08 means positive charging contactor A has stayed closed although the control module commanded it open, typically because the contacts have welded. The module notices this when voltage remains on the charging side, for instance at the charge port once a session has ended, as a Toyota patent on charge-relay sticking explains. GM stores P0D08 in the BECM of the 2023 Cadillac Lyriq; bulletin 23-NA-096 traces a joint setting with P0D0F to a software fault after an interrupted level 2 AC session and confirms it with a one-minute test charge. Stellantis lists P0D08-00 for the 2024–2025 Ram ProMaster EV with MIL and a vehicle that may not enable, remedied by BPCM reflash. The negative side is P0D0F, the opposite fault P0D09. A live inlet is a safety risk, so charging or driving gets locked out.
P0D08 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D08
- Malfunction indicator lamp and high-voltage service message
- Charging refused
- Vehicle may not switch to ready mode
Common causes of P0D08
- Most likelyContactor contacts welded, for example after switching under load
- PossibleBattery module software misjudging the contactor state (GM Lyriq, Ram ProMaster EV bulletins)
- Less likelyDriver stage or coil supply that does not switch off
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D08 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 08 | The exact fault in that area. |
What to do next
- Note P0D08 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 P0D08
What does P0D08 mean?
P0D08 means "Battery Charging System Positive Contactor A Stuck Closed". P0D08 means positive charging contactor A has stayed closed although the control module commanded it open, typically because the contacts have welded. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D08?
Drive gently and only to a workshop. With P0D08 the car can go into limp mode (reduced power) to protect itself.
Will P0D08 fail an emissions test?
P0D08 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 P0D08 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0D08 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
