A friend just reconditioned the hybrid battery on his 2007 and within three weeks got the red triangle. Code is P3000. Haven't looked at the sub-codes. Dr. Prius app appears to be indicating a slight difference with Block 10. Pulled out the battery, checked the voltage and load tested each module. The two modules for Block 10 seem right in the average with the bulk of the other cells although occasionally the module shows a higher internal resistance (not reflected in the screenshots). Overall, three modules stand out as less than the others (14, 15, 22), but not significantly. Does the load test data reveal which cells should be replaced, if any? Are modules 14, 15, and 22 deficient enough compared to the others to be replaced? Also, any reason Block 10 would be problematic? If the two modules in Block 10 test okay, as far as voltage and load, is it likely the IR that is the issue? Not sure how voltage/load/IR interrelate. Even though there is not great variation here amongst the modules, the bottom line is that he is still getting the red triangle.
