My 01 Tahoe has an issue where the brake and anti-lock lights in the dash are lit all the time. Brakes work fine however it does not appear that the anti-lock feature works at all.
I don’t really care too much about the anti-lock not working or the lights on but it won’t pass my state’s safety inspection with the brake light on.

Anyone have any ideas as to what could be the cause?

Thanks in in advance for any help
