P2D5FBattery Charging System Positive Contactor C Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D5F reports that the coil circuit of plus-side charging contactor C is intact yet behaves in a way that does not match the command: the coil current, the voltage on the line or the pull-in delay drift out of their expected band without amounting to a clear open, low or high condition. No manufacturer documents P2D5F publicly, and the published GM tables contain no range test for the coil of any charge contactor. Under CARB, hybrid parts the maker chooses to monitor must show a proper response to commands. A GM patent lists usable measures: rise rate, derivative and integral of the coil current after a short pulse, compared with a reference recorded in advance. Raised resistance in a plug, a coil whose resistance has shifted and a worn driver fit this code. Opens are P2D5E, low and high P2D60/P2D61. Charging may cut out now and then.
