All vehicles* in the U.S. market will be required to implement J1979-2 or J1979-3 automotive standards. What does that mean for you? Are you ready? Do new vehicle cybersecurity standards have you stuck in park? Most SEMA members along with OEM’s are still working on these challenges. Join us for a light lunch and networking at noon, immediately followed by the technology workshop and hands-on exercises. 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 & Past Chair of SAE’s Detroit Section, Director of Vehicle Cyber Engineering at The University of Detroit Mercy, at the SEMA Garage-Detroit on May 21,2026. Raise your game to the next level. Mark Zachos will take you 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 cyber security principles for modern vehicle networks. Why?… Because model year 2027 vehicles in the U.S. 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 2027, and SAE J1979-3 (ZEVonUDS) is required for all zero-emission vehicles (ZEVs) by 2027, with some exceptions. Key Highlights include: The Founder of The Dearborn Group Inc and President of DG Technologies. Mr. Zachos has over 30 years of engineering experience in automotive electronics, cyber security, vehicle diagnostics and communications. He has authored many technical papers on On-Board Diagnostics (OBD) and in-vehicle networking; he holds more than 10 patents on vehicle communications technology. Mark is the Head of USA Technical Advisory Group (TAG) to the International Standards Organization (ISO) Road Vehicle Electronics Standards Sub-committee; he is a member of TMC, SAE and IEEE; he has been directly involved with development of over 25 light and heavy-duty vehicle technical standards. Mark is the chairman of several technical standards teams including: the American Trucking Assoc. TMC Fleet Maintenance Cyber Security Task Force, SAE J1939 Network Security Task Force, SAE J3005 (OBD “dongle” security), SAE Data Link Connector Security Committee (i.e. SAE J3138 “hardening the OBD port”) and co-chair of ISO/TC22/SC31/WG2/PT-Security. He also is a member of the Oakland County (MI) Connected Vehicle Task Force focusing on secure connected vehicle deployment; teaches embedded programming, CANbus and vehicle cyber security at The University of Michigan-Dearborn; instructs hackers at the US Army TARDEC CyberTruck Challenge; and established CyberTech – the TMC service technician troubleshooting skills challenge for identifying and repairing vehicle cyber hacks.
