Q: 08 camry hybrid. Hybrid battery seems to test ok, I removed the entire pack and load tested each cell, but i still get dash light

I had check hybridSystem/vcs, etc. Removed trac batt and cleaned all copper connections of corrosion, took initial voltage reading from each of the 34 cells and all were within 0.2-0.4V (8.0V) of each other. Load tested each cell with halogen headlight for 2 min, rest for 1 min, and took final volt reading and still although approx 1V loss across all 34 after resting, +/- .03v (6.9-7.3V) they seem balanced. Replaced traction battery into car and all seemed ok. Replaced aux battery with new AGM also, just to be safe because it did show 1 dead cell at local parts store test. Now, it is 113 degrees here in Vegas so A/C is necessary, but, A/C if even on low drains the trac batt in 1-2 min if not moving and batt @50% . If i miss turning A/C off before it hits 2 purple lines, I get "checkHybridSytem" and then i have to pull the aux batt lead, let car cool and then all is good again. my question is, is there something I missed? A relay maybe or component that generally goes bad
