GM Engine Controls – New Technologies Assessment

Product Description

The General Motors fleet of vehicles has been changing rapidly over the last half dozen years. Smaller and more efficient engines now dominate a fleet of downsized vehicles. At the same time, full-size gasoline pickup trucks are still very popular. Producing vehicles with high fuel efficiency and customer demands for performance has brought interesting changes. Computer networks and safety system complexity has grown as well.

The goal of this class is to prepare aftermarket technicians for the diagnosis and repair of the new engine control systems found on GM vehicles. During the class, we will present tips and procedures that will enable the technician to diagnose these faults quickly and accurately.

After completing this class, the technician will be able to:

• Diagnose evaporative system faults
• Diagnose fuel trim faults
• Diagnose variable valve lift and timing faults
• Understand turbocharged engine fueling and evaporative control
• Be aware of common cooling system faults that may cause head gasket failures
• Diagnose high and low-speed communication faults
• Diagnose and repair common GDI faults
