CAB - Controller Anti-Lock Brakes. It's the brains of the system. The DRB, a Dodge scan tool, can read the controller, it is a dealer item. Some brake shops may have a compatible tool, I don't know. Your generic code reader will not pull these codes.

If you've ruled out the mechanical, it's time to get the codes read.

You don't have to have any repairs done at the dealer if you so choose. Just get it diagnosed (and an estimate) then leave. Expect to pay a diagnosis charge though, then fix it yourself.

 

Thanks for the info.
