    Hey y’all! I had an issue earlier with my 08 Prius it wouldn’t start, and it was giving the hybrid low battery sign. I thought I needed to jump start but it did no good. What worked for me was erasing all the codes, and the engine turned on. Note: I had the coolant control valve error code. I’m not sure if it’s an age thing or that the hybrid battery is bad or that the coolant control valve being bad triggerd all sensors.

    If you can erase all codes and start the car (once), then you most likely have a P0AA6 code for high voltage isolation fault.

    I looked the code up you said, and it looks very similar to my problem yesterday. Thanks for help!
