    Default Volvo XC60 B4 Mild Hybrid D420T8 AWD 2022r critical 12v charging error

    Hello everyone,

    As in the title, I have a problem with loading. The alternator supplies 20v voltage, but charging does not reach the 12v or 48v battery.
    In the hybrid system, I have error B16331F - Starter/generator controller Open circuit.
    Unfortunately, I don't have access to the diagram and I don't really know where to look for the problem.
