if that works, it will be random luck as i don't remember even seeing a post about a brake light switch problem on this car.Update
Ok so far, no dash lights coming on (Anti Lock, PCS, Trac off, and Service Vehicle soon).
Hopefully the brake light switch replace solved the issue.
Will post more updates.
Here is a scanner for ~$90 that will read GM ABS codes, but does not have real-time data display:
INNOVA 3100 Diagnostic Scan Tool/Code Reader with ABS and Battery Backup for OBD2 Vehicles
Thanks a bunch for posting all of this. Exact three same codes c0550, c0898, c0896 just lit up for me on my 2000 intrigue. They just randomly show up in the middle of a drive and then clear at the next startup. Starting to get more and more common though.
I'll give a shot at getting the module rebuilt.
