P0D8ABattery Charger Coupler Status Indicator Control Circuit B Low

  • Generic OBD-II code · Powertrain
How the car detects it
P0D8A means channel B of the charge port status indicator is held at ground level when it ought to rise, i.e. a short to ground on the B line or inside its lamp. The inlet is one of the most exposed electrical points of the car: rain, car-wash water and road salt reach it every time the flap opens, so corroded or wet contacts that bridge to ground are a frequent finding. No manufacturer documents P0D8A publicly; the closest published logic is GM's P0D2C test on the Volt, which checks for a grounded LED line while the lamp is commanded on and sets a Type B fault. The channel normally switches off to protect its driver, so the related colour or segment remains dark. Charging is not restricted. P0D89 covers an open B circuit, P0D8B a short to voltage.
