P0D08Battery Charging System Positive Contactor A Stuck Closed
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- 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.
