Security Link™

This feature is not available on all diagnostic tools.

To protect vehicle communication networks from unauthorized access, OEM’s are implementing secure gateway modules that only allow authorized users to access certain diagnostic functions using an approved diagnostic tool.

To use Security Link you will need a compatible Snap-on diagnostic tool, and create an AUTOAUTH account as well as a Snap-on profile.

For more information on how to setup these accounts and get authorized:
