You'd need to get more vehicle specific diags connected to dig deeper
Is the check engine light also on?
If not I'm guessing you have some wiring damage somewhere or a poor earth..

1. GOOGLE those codes (proper format is for example U0019-01, not string U001901, but general/generic code is U0019, then -01 is brand/model specific, extra code and it will mean something different than plain "U0019", watch out).
2. Check if everything is working in the car, all electrical appliances (wipers, power windows, fans and so on, test everything).
3. Multiple codes from different modules (like "B" and/or "C" and/or "U") are power delivery related and/or communications (CAN). Sometimes it has something to do with a car configuration ("Proxy alignment" procedure to be redone).
Most of the time it's a: bad alternator/battery, bad main earth/ground strap, wiring damage, water ingress into plugs/sockets (under the bonnet first, for example ABS pump) and main fuse/relay box, doors wiring broken (inside the rubber boots), wiper motor, third (central) stop lamp, faulty modules (like AirBag, radio, Blue&Me) making mess in the CAN lines (to check this you need an oscilloscope - BASIC tool, yet still most automotive shops don't use it, pathetic).
Many threads like that out there (multiple fault codes), Search... Your case is not special (no need for another thread).
