New Technologies

It used to be that diagnosis was streamline and more focused but now with the addition of Can networks and new complex systems it has become convoluted and challenging. It is the intention of this class to teach a thorough understanding of the complex network systems today’s technicians will face and improve their ability to sift through the obstacles when diagnosing emission failures. This course will also give technicians the tools and understanding for diagnosing new systems such as throttle control, Direct Injections, Wide Band O2Sensors and variable cam timing. There is even a chapter dedicated to ignition systems as well as teaching the more advanced systems such as Waist Spark and Coil on Plug. It is the intention of this course to give technicians the confidence and understanding in diagnosing newer technologies that they may encounter in their daily routine of repairing failed vehicle within California smog check program. This course utilizes Materials that are proven the industry and are NATEF certified. These materials are designed for higher education and have been perfected over the years. This manual also includes sound diagnostic strategies based on real world instruction. This course also includes time in the shop with practical labs to enhance materials learned in class. These labs will require the student to hook up a scan tool to monitor OBD II system, Perform Can communication checks, identify codes, Wide band O2 sensor data, and variable cam timing data.
At the end of this course students should have developed knowledge and skills to accurately diagnose CAN communication failures, variable cam timing, Throttle control systems, direct injection and complex ignition system failures. The certificate for completion is valid for two years from the date of the final exam.
