What P0DAF means
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.
P0DAF at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.3 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P0DAF
- MIL on, often together with other battery codes
- Vehicle may not start or cannot be switched off (Jeep Cherokee hybrid)
- Reduced mild hybrid assistance
Common causes of P0DAF
- Most 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
- Less likelyBleed resistor or switch of circuit A with changed resistance
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DAF means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| AF | The exact fault in that area. |
What to do next
- Note P0DAF 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 P0DAF
What does P0DAF mean?
P0DAF means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DAF?
Drive gently and only to a workshop. With P0DAF the car can go into limp mode (reduced power) to protect itself.
Will P0DAF fail an emissions test?
Yes, it can. P0DAF 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 P0DAF to fix?
Difficulty: workshop only. A typical repair takes 0.3 to 6 hours of work. This is a job for a workshop.
Will P0DAF 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.
