P0DAF Hybrid/EV Battery Cell Balancing Circuit A Range/Performance

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.

Likely causes

Battery pack control module software with an oversensitive check (FCA bulletins 08-030-24, 08-186-26)
Weak or deeply discharged cells that respond differently to balancing, e.g. after cold cranking
Bleed resistor or switch of circuit A with changed resistance

Symptoms

  • MIL on, often together with other battery codes
  • Vehicle may not start or cannot be switched off (Jeep Cherokee hybrid)
  • Reduced mild hybrid assistance
