Q: What does code P0B3C mean?

Hybrid/EV Battery Voltage Sense A Circuit Range/Performance. P0B3C indicates that the hybrid or electric vehicle battery pack's voltage sensing circuit for 'A' is reporting a voltage reading that is outside the expected range or is not performing as designed. The battery energy control module compares the sensed voltage against other cell groups and flags this code when the signal is implausible, erratic, or inconsistent with the pack's overall state of charge.
