NACE Automechanika

This class demonstrates how to use the multichannel oscilloscope, and in combination with the scanner show the winning combination for diagnosing engine management subsystems and components as they relate to an incomplete combustion, which results in misfire DTCs and/or spark plug failure. Technicians will learn how to:

• Connect the oscilloscope in late model coil on plug 2, 3 and 4 wire coils.
• Read primary and secondary coil sample patterns
• View combustion through the spark plug voltage and current patterns for ION sensing and compression sensing technologies
• Relate scan data with scope patterns

This course will also cover two case studies:   

• GDI carbon deposits intermittent misfires and misdiagnosis caused by modern engine management strategies
• PCV and Active Fuel Management causing spark plug damage
