What you'll learn in this engineering training:

The main focus of the class is to teach the diagnostic strategies today’s technicians should follow to minimize their diagnostic time and improve accuracy. This class will emphasize the utilization of the diagnostics systems that are built into to today’s vehicles such as Mode 6, Fuel Trim, and Emission Diagnostic Monitors, and is especially helpful for the new smog program that utilizes the DAD for emission testing. 

The class begins with a chapter on basic computer operation as a refresher how the computers work and how it makes decisions, then discusses the OBD II system purpose and function, then moves on to some diagnostic approaches such as the 8 step approach, Symptom based diagnostics, Mode 6, and Fuel trim diagnosis.

The diagnostic strategies discussed in this book are valid and real world. 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, identify the 9 modes of operation in the global OBD II system, Interpret Mode 6 Data, and perform Fuel Trim calculations. 

When finished the student should have developed knowledge and skills to accurately diagnose most symptoms based and code related concerns of failed vehicles.
The certificate for completion is valid for two years from the date of the final exam.

If you fail to return this equipment, including books, or other materials, in good condition within the 30 day period, the school may deduct its documented cost for the equipment from any refund that may be due you. Once you pay for the equipment, it is yours to keep without further obligation.
