    Disconnect the ICP (inverter coolant pump), then replace the AM2 fuse. You can replace the pump after you're sure that is the problem. If you don't first disconnect (or replace) the pump before replacing the AM2 fuse, then the fuse will blow again.

    The AM2 fuse is "#31 AM2 15 amp “IGN” fuse, ignition system", it should be labeled on the inside of the engine fuse box cover.

    Best to just pull and post the codes here.

    You stated having many dash lights illuminated (including the "Red Triangle of Doom"), my WAG is it has finally failed you :whistle:

    I have a SG2/Xgauge it doesn't pull comprehensive hybrid codes.

    I have the mini vci but it was a cranky install. I primarily use the VXDIAG OBD Tester Amazon.com $77. Full Techstream.
    Includes the OBD dongle you just plug the little box into the obd port and then its USB into a laptop.

    I don't use my good Win10 laptop I use a old Dell XP burner laptop.
