    The Air Coniditoner is not working, hooked up the 134 gauges static pressure of 80 psi. I pulled the 20 Amp HEV fuse the engine started the fans came on, the AC compressor did not engauge, jumped the AC pressure switch the fans came on, no compressor reinstalled the HEV fuse. Got the red Triangle cleared the codes., hoping for a code reset but no. Now it will not start only goes from park to netural, will not set codes.

    Did i kill my HV invertor?

    I replaced the HV battery (new from Toytoa) 10 months ago. I have invertor coolant flow, the 3 way coolant switch connector is clean, HV connections are clean.

    Going to get the 12V battery tested scanner shows 11.6V.

    Help!!!

    Does anything light on the dash now? The triangle perhaps?

    The lights that are on are traction control, circle with ! in it, ABS, VSC, check engine, and tire sensor. The tire sensor is always on. The gas gauge is flashing on empty, but the car has 3/4 of a tank of gas, and of couse the red triangle. The scanner that I'm using is a CGSULIT SC880.

    I'm not familiar with that particular scan tool, but scan tools that can't show you all the codes your Prius has are quite common.

    Because the triangle is on, it would be very helpful to find out the associated code(s), which will require getting access to another scan tool.

    The codes behind the brake/skid/abs lights can be retrieved without a scan tool, this way:

    Blink (a/k/a Flash) Codes – How to. | PriusChat

    You'll probably have at least 58 on the ((!)) light and/or 51 on the VSC light, both of which only tell you there are hybrid codes you need to retrieve, though you kind of already know that.

    From your symptoms, I wouldn't be surprised if P0AA6 with inf code 611 or 614 is among your hybrid-system codes, but it would be good to confirm that with a scan tool.

    What third party scanner works best with a Gen 2?
