What does code P2E8F mean?

Q: What does code P2E8F mean?

Battery Charger B Charge Sequence Signal 2 Circuit Low. P2E8F indicates that the powertrain control module (PCM) has detected a low-voltage condition on the charge sequence signal 2 circuit for battery charger B, which is typically part of a high-voltage battery charging system on electrified vehicles. The PCM monitors this dedicated signal line to confirm that the charger is executing the correct charging steps, and a low signal means the circuit is grounded, shorted, or the charger is not reporting the expected sequence.
