P0D09 Battery Charging System Positive Contactor A Stuck Open

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Contactor mechanically failing to close or burnt contacts
Fault in the on-board charger or integrated charging unit (Kia ICCU bulletin)
Control software needing an update (Stellantis, GM Lyriq)
Missing coil supply because of a wiring or fuse fault

Symptoms

  • 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
