[s-cars] Resetting Fault Codes on ABS 1992 S4?

[Cody Payne]

Anyone know how to reset the ABS fault code on a 1992 S4?  I have a VAG tool and 2x2 adapter but not sure that the 92 allows you to access the ABS via normal VAG 2x2 interface.  Still trying to diagnose my issues from this AM's jumpstart.
- Radio NO Power (Could be fuse behind the head unit...need to pull to check..coat hangers?)
- ABS Light stuck ON on console..pushing ABS switch does nothing
- No Cell Phone Power

Thx
