Stability control and abs light on

[ObiRamKenobi]

I recently bought a 2021 1500 bighorn rocky ridge k2 28K miles and last night I had to brake hard. The abs and stability control lights came on I cannot use the 4 wheel drive and when I put the truck in reverse it says rear brake assist disabled. There are no error codes in OBD showing the truck functions properly outside of those systems. Nothing is damaged and I disconnected the battery for about five minutes and the lights will not go out and systems come back online. The switch on the center console always doesn’t work for stability control. Any else have this issue and can help? I saw other threads all related to speed sensor but they talked about a code being present which I am not showing.

Alfa OBD, OBD link MX+ or equivalent and a security gateway by-pass cable. I would start with that.
