Because modern vehicle electronics are increasingly threatened by tampering and hacking attacks, more and more vehicle manufacturers seek to protect access to the diagnostic data of their new vehicle models. However, Bosch can assist workshop with gaining easier access to such data. 

Restricted access to data can make it impossible to perform active diagnostic tasks such as the calibration of driver assistance systems or service functions. As a result, independent workshops face technical and administrative challenges because some vehicle manufacturers use proprietary security solutions with different access requirements and payment concepts.

Bosch offers a solution in the shape of Secure Diagnostic Access (SDA). As part of the ESI[tronic] Evolution diagnostic software, SDA enables unrestricted work on vehicles with protected vehicle electronics in the future. Access is available for various vehicle manufacturers and models and is continuously being expanded by Bosch. SDA is supported by the latest generation of Bosch diagnostic tools, including the KTS 560, 590, 350 (and KTS 250 with limited functionality).

Instead of separate diagnostic devices and licences for each manufacturer, just a one time registration for SingleKey ID and online user identification are required. This will allow access to all participating manufacturers.

Since 2021, SDA from Bosch has meant full speed ahead for extensive diagnostic work on access-protected vehicle electronics. The current brand coverage includes: 

• Alfa Romeo 
• Audi
• Chrysler
• Dacia
• Fiat
• Ford
• Hyundai/Kia
• Jeep
• Mercedes-Benz
• Nissan
• Polestar
• Porsche
• Renault
• Seat/Cupra
• Skoda
• Subaru
• Volvo

With the integrated and standardised Secure Diagnostic Access solution, Bosch continues to provide centralised access to secure vehicle data through ESI[tronic] Evolution diagnostic software and the brand coverage continues to grow.
