All vehicles* in the United States market will be required to implement J1979-2 or J1979-3 automotive standards within the next few years. What does that mean for you? Are you ready? Do new vehicle cybersecurity standards have you stuck in park? Most SEMA members--along with OEMs--are still working on these challenges.
Join SEMA Garage Detroit and DG Technologies next month for a light lunch and networking event, immediately followed by a technology workshop and hands-on exercises that will keep you informed and up-to-date on the latest diagnostics standards. Learn more about these topics and get answers to your advanced-vehicle protocol questions with J1979-2/3 expert Mark Zachos, president DG Technologies, SAE fellow and past chair of SAE's Detroit section and director of vehicle cyber engineering at the University of Detroit Mercy.
During the workshop, scheduled for May 21 at SEMA Garage Detroit in Plymouth, Michigan, Zachos will take attendees through the software-defined diagnostic standard and the basics of access control features based on J1979-2/3 standards for compliance and integration. He will also provide insights into cybersecurity principles for modern vehicle networks.
Why? Because model-year '27 vehicles in the United States market will become even more software-dependent and access-controlled, understanding OBDonUDS is critical for compliance, integration, development, secure diagnostics and long-term aftermarket reliability. Knowing these standards will help you solve problems and save you time.
* SAE J1979-2 (OBDonUDS) becomes mandatory for all internal-combustion vehicles by model-year '27, and SAE J1979-3 (ZEVonUDS) is required for all zero-emissions vehicles (ZEVs) by '27, with some exceptions.
Key Highlights include:
- Background of SAE J1979 classic, emissions compliance and global diagnostics
- Key distinctions and use cases for J1979-2 (Updated OBDonUDS) and J1979-3 OBD diagnostic test modes for Zero-Emissions Vehicles (ZEVonUDS)
- Defined information on Over-the-Air (OTA) updates, DoiP and Secure Gateway Modules
- Cybersecurity implications of diagnostic data access in modern vehicle networks
