This session explains how to conduct fast, consistent in‑vehicle testing for the environmental diagnostics regulatory protocols SAE J1979‑2/3 (OBDonUDS/ZEVonUDS). By standardizing regulation‑based test procedures and automating compliance checks (J1699‑5 Static/Dynamic, ZEV), we cut repetitive work; and by automating the acquisition and comparative validation of regulatory DA (Digital Annex) data, we lower certification risk.
