The OBD-II Protocol Training is a specialized program designed to provide participants with a comprehensive understanding of the On-Board Diagnostics – Second Generation (OBD-II) protocol. OBD-II is a standardized communication protocol used in vehicles to monitor and diagnose various components and systems for emissions control and performance monitoring. This course aims to equip students with the skills and knowledge to work with OBD-II protocols, interpret diagnostic trouble codes (DTCs), and perform vehicle diagnostics effectively. Through theoretical lectures, hands-on lab sessions, and real-world projects, students will become proficient in the OBD-II protocol and gain the ability to diagnose and troubleshoot automotive systems using OBD-II tools and techniques.
