Advanced Diagnostics

This course has been written as an extension to Diagnostic Day One and concentrates on the use of code readers and oscilloscopes for automotive diagnostics. The course will cover the function of oscilloscopes and their practical use. At the end of this course the technician should be able to identify common automotive based wave forms as well as be able to test a component for correct operation using both serial and parallel signals.
