Check to see if anyone has made the '19 shop manual available on this site....
If not, grab the one that covers the preceding generation (13-18), and see if the buttonology is the same to read codes.
Odds are very good, your bike doesn't like your alarm installation.... Whether that is due to where and how you installed, or if the alarm is actually compatible with your bike, would be the question.
Can you remove the alarm and clear the check engine light?
