P2E8FBattery Charger B Charge Sequence Signal 2 Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E8F reports the second CHAdeMO sequence line pulled low at a time it should be released. Because the station uses d2 to connect this line to ground as the very last step before the vehicle closes its contactors, and opens d2 first when the session ends, a line already at ground early, or still at ground once d2 is open, contradicts the sequence. A ground short in the inlet or harness, a station switch d2 that sticks closed, or a faulty input stage can be the cause. The vehicle then cannot be sure its contactor release is controlled by the station and normally refuses or aborts DC charging. No manufacturer documents P2E8F publicly; Siemens' CHAdeMO library for charging stations shows the station side, with relays d1 and d2 rated for 2 A. The high counterpart is P2E8E.
