P2E8DBattery Charger B Charge Sequence Signal 1 Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E8D means the vehicle finds the first CHAdeMO sequence line low while the fast charger should be driving it. Signal 1 is the opening move of a session: once the plug is detected the station closes d1 and applies 12 V, and only after that does the CAN exchange of battery limits begin. If the vehicle side sees no voltage, the session stalls before any current flows. The line can also supply contactor coils in the car, which is why the standard allows up to 2 A on it; a short to ground therefore loads the station switch hard. No manufacturer documents P2E8D publicly. Reasons include a short to ground, a broken wire or pin 2 contact, a corroded inlet, and, on the station side, a switch d1 that never closes, so trying another charger helps narrow it down. The high counterpart is P2E8C.
