Snap-on diagnostic platforms approved to access Mercedes-Benz gateway modules

April 22, 2025
For vehicles with the secure gateway module, access to certain diagnostic functions requires registration and authentication through an approved device.

Snap-on's diagnostic platforms have been approved by Mercedes-Benz and certified by the Auto Authentication Authority (AutoAuth) to access Mercedes-Benz vehicles' gateway modules. Snap-on Wi-Fi-enabled products operating the latest software can work with Mercedes-Benz secure systems. 

Automobile manufacturers are developing solutions to protect vehicles' networks from unauthorized access, including potential cyberattacks, by securing vital systems behind gateways. Mercedes-Benz has implemented a secure gateway module that was introduced during the selection of 2021 and newer model vehicles. For those vehicles with the secure gateway module, access to certain diagnostics requires registration and authentication through an approved device for all aftermarket scan tools. 

The Security Link from Snap-on provides diagnostic platform owners a uniform method to access secured vehicle systems from their diagnostic tool gateway modules. Security Link is included with the current software at no additional charge.
