Year 3 Outline & Class List

Case Studies – Version 2:

• Using case studies from real world vehicles, students will use their diagnostic skills to solve the vehicle’s problem
• Variety of techniques will be used including current probe diagnostics, scan data interpretation, scope pattern interpretation and oxygen waveform sensor diagnosis
• Each of the vehicles involved were to several shops before finally being diagnosed properly
• Students will be guided in logical steps using information and screens gathered from the vehicles
• Students are encouraged to bring their own problem vehicles for the class and they will be used for a hands on demonstration of the techniques involved

• All vehicles used for examples in this class had been to numerous repair facilities before being correctly diagnosed
• Here is a chance to see the common errors and ensure that you don’t fall victim to them.

No Start Diagnosis:

• What to do when the engine has good fuel pressure, good spark and good injector pulse but will not start
