The vin has to be distributed all through out your vehicle's computers ( which are networked) in order for the systems to work, so if one one of the main computers can't register the vin, then it shuts down different systems and triggers the ABS and Check Engine lights etc. I would try a shop that can re-enter the vin, which may have to be the dealership. They usually are the only ones with the vin capable scan tool for theft reasons.
