Autel U.S. has announced it now offers access to Mercedes-Benz enhanced gateway-protected systems.  

Autel has been approved by Mercedes-Benz USA and certified by the Auto Authentication Authority (AutoAuth) to access the enhanced security gateway on select 2021 and newer Mercedes-Benz vehicle models and perform previously restricted operations in the body control module, including ADAS calibrations. 

This capability enables Autel users to perform all “ordinary use” diagnostics, including special functions, active tests, data flow analysis and ADAS calibrations on all Autel tablets in North America with an active subscription and AutoAuth account, according to Autel officials. 

“Autel's goal is to provide technicians access to the latest critical functions to accurately and efficiently diagnose and repair their customers' vehicles,” says Paul A. Marshall, director of product development for Autel U.S. 

“With access to this enhanced gateway, Autel users can now perform additional services, including ADAS calibrations, on the latest Mercedes vehicles." 

Autel officials continue by saying Mercedes-Benz started integrating a security gateway module in specific 2021 vehicle modules to protect critical vehicle systems from unauthorized access and cyberattacks. Before AutoAuth tablet certification, only Mercedes-Benz diagnostic software and tooling could access these systems and perform diagnostics, service, resets and calibrations.  

Mercedes-Benz vehicles with security gateway modules include 2021 or newer CLA (174), CLA (178), AMG GT (192), C (206), E (214), S (223), SL (232), CLE (236), GLC (254), EQE (294), EQE (295), EQS (296), and EQS (297). 

Technicians can also access, along with Mercedes-Benz, Nissan and Stellantis vehicles with a security gateway through an AutoAuth-registered Autel tablet.  

Autel officials say they negotiated with the Volkswagen/Audi Group to add security gateway access capability to its diagnostics and service tablets, and earlier this year, they added the functionality to Autel’s tablets.
