P2D5EBattery Charging System Positive Contactor C Control Circuit/Open
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D5E concerns the wire that energises the coil of plus-side contactor C, not its power contacts: the module finds that the state of its output driver and that of the line disagree, typically because a wire or the coil winding is broken. No manufacturer documents P2D5E publicly. GM's check of the contactor A counterpart (P0D0A) gives typical criteria: an output reading above 4 V while switched off, or under 57 mA of coil current while on, counts as an open; 40 bad results out of 50, sampled every 12.5 ms, are needed, and the 2016 Volt rates it Type B (two trips), the ELR Type A. Look for a broken wire, a terminal backed out of its plug or an open coil. Range, low and high are P2D5F–P2D61. Contactor C cannot pull in, so its charging mode is lost.
