During a DE run, I got a "Battery/Alternator Failure" Warning. Came into the paddock with 11 volts showing on the instrument cluster. Diagnosis - alternator failure. When I started the car again to load it on the trailer, I got "Brake Distribution Failure" and "ABS Failure" warnings. Started the car one more time at home to unload from trailer.

I have since replaced the alternator and battery, volts show 14.5, but Brake and ABS failure warnings continue. My (admittedly cheap) OBD2 scanner shows no codes.

Are these warnings triggered by just the low voltage after the alternator failure?

Is the car safe to drive until I can get a friend with a Durametric to find and reset the warnings?

I think once u run car those warnings will reset to normal. Mike

Have started it several times, and taken about a 5 mile drive. Alternator/Battery warning is gone, but ABS and Brake distribution continue.

You may have to clear the ABS codes with a PIWIS tester and cycle the system for the faults to clear. Some cars are this way while some are not
