- How the car detects it
- P0D10 means negative charging contactor A does not close when told to, so the charging path never gets its return line and the session fails. Ford names it in the BECM of the 2021–2023 Mustang Mach-E next to main-contactor codes; the bulletins (23-2020, 23-2257) replace the high-voltage battery junction box and update the BECM. GM's preliminary PIT6083 for the 2024 Lyriq links P0D09 and P0D10 to very long charging sessions and advises disconnecting the cord once a day for 20 minutes or more until new software arrives. Stellantis lists both codes for the Wagoneer S and Charger Daytona, where a no-start can follow, and handles them with BPCM updates. Welding on this side is P0D0F, the control circuit P0D11, the positive counterpart P0D09. Expect charging to stop.
