ABS not available sometime

[Hamza]

I have Ford explorer St 2022.
Recently, I had a problem after a weak battery. I recharged from a friend's car. Suddenly, a malfunction occurred in the brake system ABS, as several warning signs appeared on the instrument panel and the brakes were lost. When I did a comprehensive check, nothing was found in the brake system or its control unit ABS, but the warning signs were still active and the brakes were lost. After that, I disconnected the negative battery terminal for a few minutes, then restarted it. All the warning signs disappeared and the brakes were activated again. I drove the car for three days and everything was normal, then the same problem returned: the warning signs appeared and the brakes were lost, but this time for longer periods. Even after reconnecting the battery and reprogramming, things remained the same, and the fault scanner did not register any faults in the brake control unit ABS. I don't know exactly what happened because there are no fault codes.
and no any problem with CAN bus,
A confusing and unclear situation. Please help me with a solution to this problem.

Weak voltage can give you strange problems. Good chance your battery needs to be replaced if it was dead or near dead. I would start there before diving into the abs system
