P2E8CBattery Charger B Charge Sequence Signal 1 Circuit High

P2E8C indicates that the powertrain control module has detected an abnormally high voltage on the charge sequence signal circuit for battery charger B, which is typically part of a high-voltage battery charging system on electrified vehicles. The circuit is expected to carry a specific voltage or duty-cycle signal, and a high reading means the module sees a short to voltage, an open return path, or a charger that is not responding correctly to the commanded charge sequence.
