P2D6CBattery Charging System Positive Contactor D Control Circuit/Open
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D6C covers the coil supply of positive charging contactor D rather than its main contacts. The module finds the line in a state that contradicts the command to its driver, mostly due to an interrupted wire or coil. No manufacturer documents P2D6C publicly. GM's 2016 check of plus contactor A (P0D0A) looks at both driver states: with the driver off, more than 4 V on the line means open; with it on, a coil current below 57 mA does too; the code needs 40 of 50 samples failing, Type B on the 2016 Volt and Type A on the ELR. CARB requires output circuits to be checked for lost continuity. Contactor D then stays out and the charging mode it serves is unavailable. P2D6D–P2D6F are the other drive faults, P2D73 the minus side.
