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.

Likely causes

Module or cell group of section I aged beyond its limit
Uneven pack temperature stressing this section
Misjudged state of health in the battery controller

Symptoms

  • MIL or hybrid system warning on
  • Shorter electric range
