GM has introduced a new line of vehicles called the Cobalt. The Cobalt has individual unique features. This course will cover the mechanical features of the 2.2L ECO-TECH Engine, Electronic Throttle Control, Computer Controlled Start / Crank System, Electronic Power Management System including the Required Voltage Control System. The list of changes continues.

Complicated vehicles with interrelated systems still break down. Even deciding which system is at fault can be a problem. No single piece of test equipment will diagnose every problem for you. This course is intended to help you diagnose late model GM Drive-ability issues. The course begins with teaching GM Strategy Based Diagnostics. It then continues with Diagnosing Ignition, Fuel Delivery, and PCM Code Diagnostics. Scan Data Interpretation will be highlighted in class.

Case Studies from numerous GM Vehicles will be providing test Data. A late model Prop will be used.

GM has used numerous types of ignition systems over the past years and throughout their various vehicle lines. Many of the systems currently in use are many of the Ignition systems currently In use are older Ignition systems that have evolved over the past number of years.  Keeping up with the numerous types of Ignition systems can be overwhelming.  When the vehicle is in your bay you are required to make a quick and accurate diagnosis of components that are sometimes hard to access.  Flow charts can seem inconclusive. More often that not the problem is intermittent. Maybe it really did need both crank sensors and a cam sensor and a module and a PCM and a coil all at once??? This course is designed to help you diagnose and repair various GM ignition systems and related problems.  We will focus primarily on GM vehicles from the early 1990's to the early 2000's.   The information presented here will help you diagnose quickly and efficiently, the various GM ignition systems. A working model of an Opti-Spark will be used to facilitate training. This course Is designed for both apprentices and journeyman technicians.

All manufacturers build vehicles to meet consumer demands for greater “creature comfort”.  Air conditioning is almost considered standard equipment on all vehicles.  While basic air conditioning operation remains unchanged, the controls for air conditioning continue to change.  Mode operation and even fan speed controls continue to evolve.  Even though the PCM controlling the compressor is not a new concept, how the AC request is sent to the PCM varies greatly among vehicle lines.  Often multiplexing and/or the BCM is involved in the AC request signal even on simple vehicles.

This course will cover GM HVAC controls including front and rear truck controls and some dual zone systems.  This course will also teach how multiplexing is involved in AC controls.  Basic AC operation will be reviewed, but this is not a basic course. GM Trucks and Cars will be covered.
