Hi, I would use a diagnostic tool capable of clearing "U" codes before anything else. It's likely that code was set by low battery voltage. Your monitors need to set - and more driving is needed to get that to happen. Try to stay between 55-60 MPH on cruise control for 15 minutes or so. Don't deviate or you'll have to start over. Need an open stretch of road with limited traffic. This is just one element of setting a drive cycle but it's an important one, so try that first. Beyond that, seek the guidance of a local shop that can help. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
