Gen 2 Prius taxi came in with hybrid light and check engine light. We pulled the codes and got P3000 and P0A80 (REPLACE HYBRID BATTERY PACK). We checked the freeze frame of P0A80 and noticed one of the battery cells block was below average at 12v normally 14v. Then we checked delta state of charge and normally its at 0 but we were reading at 43%. Any reading not 0 on delta SOC shows that the something is not right with battery.
We sat in the car for about ten minutes and the HV battery suddenly became fully charged. This is another indication of abnormal behavior because HV batteries normally take longer to fully charge. After we concluded the HV battery was bad. I did my first gen2 hybrid battery replacement. Pretty cool day
