What does code P0DC5 mean?

Q: What does code P0DC5 mean?

Hybrid/EV Battery Cell Balancing Circuit G Stuck On. P0DC5 indicates that the hybrid or electric vehicle battery management system has detected that the cell balancing circuit for group G is stuck in the active state, meaning the balancing resistor or switch for that cell group remains engaged when it should be off. The computer monitors the balancing circuit and sets this code when the circuit's commanded state does not match the actual state, typically because the balancing transistor is shorted or the control line is grounded.
