What are the common causes of P0DC2?

An open balancing shunt on circuit F. A cell controller that never commands circuit F on. A balancing transistor on circuit F that will not conduct. Broken wiring to the circuit F balancing resistor.

Compare the circuit F cell group balance to the others. Command balancing on and watch for any change on circuit F. Check continuity of the circuit F balancing resistor and wiring. Inspect the cell harness connector at circuit F. Service the balancing board if the circuit F path stays open. Clear the code and retest.
