Bosch is First Aftermarket Scan Tool Manufacturer to Unlock and Diagnose 2018 and Newer FCA Vehicles in software version 3.7

WARREN, Mich., –Bosch announced today the release of software version 3.7 for the ADS 325 and ADS 625.

Starting with many 2018 and newer models, FCA US requires a diagnostic tool to be compliant with their tester authentication process to perform many diagnostic functions.  Applicable vehicles include many models under Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo brands.

How is this accomplished?  The diagnostic tool will still connect under dashboard to the 16 pin DLC, and via an internet connection, will obtain security credentials that are understood by a vehicle-mounted Secure Gateway Module (SGW).  This module keeps vehicle communication networks secure and protects electronic control modules from being exposed to potential hacking.  Think of the SGW as a device similar to a firewall.  This changes how aftermarket diagnostics work.

What diagnostic functions are affected?  Certain functions like reading codes or live data are not impacted.  But any functions that require performing actions or changes to the vehicle systems, like clearing codes, relearns, actuations, adjustments, now require the diagnostic tool to complete an authentication process and “unlock” the SGW before performing these functions.

Only the FCA US dealership diagnostic tool has been supporting scan tool authentication for SGW unlock.  Until now.

Bosch, in partnership with FCA US and Industry, is the first aftermarket diagnostic tool manufacturer to develop the technology to unlock the SGW.  Bosch has released this feature as a Beta Test with the May 3.7 software release on Bosch ADS 325 and 625 platforms initially.  Other Bosch manufactured diagnostic platforms will follow in coming weeks.  The Beta test will allow customers to follow the FCA US prescribed method by legally and quickly diagnosing all vehicles equipped with the SGW seamlessly and within seconds.  Only an internet connection and active tool subscription are required. **

Bosch software version 3.7 also includes:

• Pre and Post-Scan Coverage for 2019 model year Alfa Romeo, Chrysler, Fiat, Honda, Jeep, Mazda, Nissan, Subaru and Toyota
• ADAS Camera Dynamic Calibrations for 2008-2018 model years BMW, Chrysler, Ford, GM, Honda, Hyundai, Jeep, Kia, Mazda, Mitsubishi and Volvo
• Special Tests for 2017-2018 model years Ford, GM and more
**Secure gateway unlock feature can be interrupted during the course of the Beta test at any time.  Service offering conditions subject to change with official release.
