An advanced-level course in the application of diagnosing, locating, and correcting trouble encountered in automotive service, using various types of testing equipment. Engine diagnosis includes variable cam timing and variable displacement engine systems. Compression analysis including cylinder compression testing and cylinder leak down testing. Fuel system diagnosis includes pressure and injector tests using active commands and relative flow analysis. Cooling system evaluation and testing, including identification of cooling system components. Coursework also explores various common problems that occur in the servicing of the modern automobile. Ignition system diagnostics that includes the use of secondary ignition scope and electronic system testing.
