P2CCFHybrid/EV Battery Pack J Deterioration
- 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
- P2CCF belongs to the deterioration series that rates each section of a divided traction battery on its own; J is the tenth section after A (P0A7F), B to F (P0EDD–P0EE1) and G to I (P2CCC–P2CCE). It is not an electrical fault: the controller has decided that the modules of section J have given up more usable capacity or power than allowed. No manufacturer publicly documents P2CCF. The nearest documented case is the Audi Q5 PHEV, whose battery manager reports eight groups and therefore ends at P2CCD. CARB wants faults of individual storage parts such as cells to point at the smallest unit a workshop can renew; a lettered section series follows that logic. Overheating of the same section has its own code, P2D4E. Likely consequences are the MIL, less electric range and possibly reduced drive power.
- What you may notice
- MIL or hybrid system warning on
- Electric range noticeably shorter
- Less power available in electric driving
- Likely causes
- LikelyModules of section J worn beyond the accepted capacity or power limit
- PossibleSection J repeatedly ran hotter than the rest of the pack
- RareHealth estimate of the battery controller wrong after software or sensor issue
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
