    2013 Prius had recently hit 200k+ miles and was giving me codes P0A7A & P0A94 after check hybrid system message appeared. I am the second owner of the car and was sold to me as is from a dealership. After replacing the inverter and clearing codes I test drove the car for about 30 miles around town and no issues. The next day the check hybrid system message appeared again but is now showing U0110 under hybrid control codes. Is replacing the Drive motor control module the next step?

    The error code U0110 has subcodes.
    The problem is seen in the connections between the inverter and the power management control ECU (HV CPU).

    Trouble Area:
    Wire harness or connector
    Inverter with converter assembly
    Generator cable
    Motor cable
    Hybrid vehicle transaxle assembly
    Power management control ECU
    PCU fuse
