P0DAFHybrid/EV Battery Cell Balancing Circuit A Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0DAF is a plausibility code: circuit A switches and is electrically intact, but the effect on the cell voltages does not match what the controller expects. FCA is the visible user. Ram 1500 pickups with the 48 V eTorque system (2019-2024, bulletin 08-030-24 and its yearly versions) list P0DAF among the MIL codes fixed by new BPCM software. The 2026 Jeep Cherokee 1.6 hybrid (bulletin 08-186-26) logs P0DAF-00 together with low cell voltage P0DE6; the car may not start or switch off, and the update improves the robustness of the P0DAF check. So a software update is the first step before touching hardware. Pure circuit faults are P0DAC, stuck states P0DAD and P0DAE.
- What you may notice
- MIL on, often together with other battery codes
- Vehicle may not start or cannot be switched off (Jeep Cherokee hybrid)
- Reduced mild hybrid assistance
- Likely causes
- LikelyBattery pack control module software with an oversensitive check (FCA bulletins 08-030-24, 08-186-26)
- PossibleWeak or deeply discharged cells that respond differently to balancing, e.g. after cold cranking
- RareBleed resistor or switch of circuit A with changed resistance
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
