The chart below has a list of participating automakers. It shows the types of information available, model/year coverage, the geographic limitations (if applicable), tools required to perform security-related services, and links to service information websites. Most automakers are participating; some in California only, initially, while others are participating on a national basis.  File will be updated periodically as needed.
