    Yes, they are all on. I have the red triangle, the check engine, the brake, and the vsc lights on. I put in a new high voltage battery this past summer so what now? Any suggestions?

    did you put a brand new battery from Toyota? There could be many things that cause the triangle, but if you have a refurbished battery, that's where I would look first.

    Check the inverter coolant reservoir for fluid turbulence. If you do not see this, the inverter coolant pump has a problem.
    Make sure the 12V battery is in good condition.
    Get Mini VCI to read the DTC if there are no obvious problems that you can see and fix.
