Hybrid/EV Battery Cell Balancing Circuit G Stuck Off
Powertrain system Generic code P0Dxx codes Check engine light
What P0DC6 means
P0DC6 is set when circuit G stays idle although balancing is requested, so group G cannot give up charge. Ford names the code in its 2015 hybrid OBD summary and decides it from the start-up voltage comparison of the six cells per circuit. Ford's own patent application US20130030617A1 shows why this matters during charging: a resistor placed across a nearly full cell routes some of the charging current past it, or the higher cells are bled down at the end and the pack is topped up again. With circuit G dead, neither route works, and the cells of G define when charging must stop. The driver sees a slowly shrinking electric range, not a breakdown. Detecting it is a CARB requirement for hybrids. Opposite: P0DC5.
P0DC6 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1.5 to 8 hours
- Clears after repairAfter a drive cycle
Symptoms of P0DC6
- Electric range shrinks gradually over weeks
- Charging stops before the indicated target
- Check engine light without immediate drivability change
Common causes of P0DC6
- Most likelyShunt resistor of group G open, no current can bypass the cells
- PossibleBalancing switch of group G does not close on command
- Less likelyPin backed out of the cell harness connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DC6 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C6 | The exact fault in that area. |
What to do next
- Note P0DC6 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0DC6
What does P0DC6 mean?
P0DC6 means "Hybrid/EV Battery Cell Balancing Circuit G Stuck Off". P0DC6 is set when circuit G stays idle although balancing is requested, so group G cannot give up charge. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DC6?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0DC6 fail an emissions test?
Yes, it can. P0DC6 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0DC6 to fix?
Difficulty: workshop only. A typical repair takes 1.5 to 8 hours of work. This is a job for a workshop.
Will P0DC6 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
