P2E8EBattery Charger B Charge Sequence Signal 2 Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E8E concerns the second CHAdeMO sequence line, which works differently from the first: the station closes switch d2 to tie the line to ground, completing the circuit that sequence signal 1 feeds, and only then may the vehicle close its high-voltage contactors. Before that the connector has been latched and the vehicle has given charge permission. If the vehicle measures this line and finds it high at the moment d2 should be closed, the go-ahead for the contactors never arrives and the session ends just before power transfer; a high level outside a session points to a short to a supply. An open wire on pin 10 or a station whose d2 fails can look the same. No manufacturer documents P2E8E publicly. The low counterpart is P2E8F; faults on signal 1 are P2E8C/P2E8D.
