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.
Course Objectives: Describe the types of networks and serial
communications used on vehicles. Discuss how the networks connect to
the data link connector and to other modules. Explain how to diagnose
module communication faults. Describe the purpose and function of an
electronic throttle control (ETC) system. Explain how an electronic
throttle control system works. List the parts of a typical electronic
throttle control system. Describe how to diagnose faults in an
electronic throttle control system. List the reasons for variable
valve timing. Describe how the valve timing is changed. Discuss the
various types of variable valve timing. Explain how to diagnose
variable valve timing faults. Describe the differences between port
fuel injection and gasoline direct-injection systems. List the various
modes of operation of a gasoline direct-injection system. Explain how
a gasoline direct-injection system works. Perform a visual inspection
of the gasoline direct-injection system and identify the parts. Still
