    I have a 2010 first gen Toyota Prius
    Last night the DTC popped up which was A0943 which showed “inverter water cooling system performance “
    So I checked to see if the pump was working and the sound was coming even could feel the water flowing through the pipes but the water in the tank of the electric pump was empty
    When I checked the radiator water levels they were normal
    But the water from the electric water pump tank kept getting empty
    This is my dilemma
    Anyone can help me out as to why this would happen??

    welcome!

    are you conflating the inverter coolant with the engine coolant?
