    Hello everyone, I have code P0C73. The coolant in the inverter pump is not moving.
    I bought and installed a new inverter pump thinking that it would solve my problem. But unfortunately it didn't help the problem.
    I'm looking for advice on how I should go about troubleshooting this issue. I have checked and replaced all fuses under the hood and inside the car that were bad or looked questionable.
    Does anyone have some sort of wire diagram for it? Or a good way to troubleshoot it?

    is there 12 volts at the pump connector?

    is it an oem pump from a dealer?

    The wiring is fairly simple.
