P2CCEHybrid/EV Battery Pack I 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
- P2CCE is reserved for the ninth section, I, of a traction battery whose controller rates the health of each section on its own. The fault is a capacity or power verdict, not an electrical one: section I no longer delivers what a healthy unit should. No manufacturer publicly documents P2CCE. The nearest published use is Audi's Q5 PHEV, which splits its pack into eight groups and therefore stops at P2CCD for group 8; a battery with nine or more independently monitored modules would continue here, followed by P2CCF for section J. CARB asks for a state-of-health monitor for hybrid storage and, for faults of cells, sensors and cell balancing, for codes that isolate the smallest replaceable unit. Where it is used, expect the MIL, a shorter electric range and, as with Audi's siblings, the replacement of a single module rather than the whole battery.
- What you may notice
- MIL or hybrid system warning on
- Shorter electric range
- Likely causes
- LikelyModule or cell group of section I aged beyond its limit
- PossibleUneven pack temperature stressing this section
- RareMisjudged state of health in the battery controller
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
