Hello Everyone, i wanted to share mi finding to a common problem we all have, the famous VSC,ECM,ABS,TRACK OFF lights in the dash. I had a tech with Techstream come check out my car, he Determined it was the VSC,TRACK,ABS Module, he also recommended to change the ABM Module/Pump that is a one unit piece. Now i though i could purchase a used one and maybe reprogram it to my vehicles VIN, but I'm confused, in some forums i read they just need to be calibrated to the vehicle with TechStream for it to work, Somewhere else i read that only Lexus can Reprogram the Parts, and somewhere else i read that these Modules are not reprogrammable and that the only Solution is to buy them Brand New through the dealer, Has anyone Replaced these parts? Any Suggestions? or Advise?
