This one-hour seminar covers an overview of General Motors electric and eAssist hybrid vehicles. Topics include proper safety information for the electrical power supply system, high voltage systems, eAssist, Jump Assist and jump starting procedures. 

This self study course provides an overview of ACDelco belts and hoses including safety, component operation, service, and maintenance. 

Modern brake systems operate on the same principles that braking systems have used for over 100 years. Recent regulation changes combined with the pursuit of improved fuel economy and safety have resulted in changes in the designs. Some changes have increased the occurrences of the braking system noises. This three-hour seminar presents information on diagnosing brake system noise concerns, service tips and procedures to reduce brake noise comebacks. In addition, special service tools and ACDelco brake products are discussed. 

The seminar will cover what's new in light diesel cars and trucks. If you have not noticed, there is a new generation of common-rail diesel engines on the road today: cleaner, quieter and more powerful. Seminar topics include: GM Duramax Gen I, the Chevrolet Cruze Diesel Gen 1, exhaust aftertreatment, as well as sensors and diesel offerings from Ford, Chrysler and VW. Also discussed are safety, maintenance, diagnostics and service related to these modern diesel fuel and emission systems. 

This course covers the features of the global hybrid and electric vehicle high voltage battery systems. It provides the fundamentals of high battery voltage construction, control modules, thermal management, contactors, manual disconnect features, chassis isolation, and safety features. Upon completing this course, participants will be able to:

• Recall the fundamentals of high voltage battery construction
• Recall the fundamentals of high voltage control and monitoring
• Recall the fundamental safety features of high voltage batteries

 

This Instructor-led training Seminar provides an overview of hybrid and electric vehicle designs, operation, and servicing. Diagnosing and servicing Hybrid Electric Vehicles (HEV) and Battery Electric Vehicles (BEV) requires an in-depth understanding of their design and operation. This course covers the operation of HEV and BEV propulsion systems, driveline configurations, high voltage batteries, drive motors / generators, and charging systems. The course also covers HEV and BEV servicing procedures including high voltage safety, high voltage disabling / enabling, loss of isolation diagnosis, and range related conditions. 

This seminar provides an in-person opportunity to complete prerequisite hybrid training for Hybrid ILT participation.
Two-mode hybrid vehicle features and the safety precautions associated with servicing them will be described.
Technicians will identify unique Two-mode hybrid components and systems as they discuss system operation. Procedures for disabling and enabling the Two-mode hybrid 300 volt battery system will be explained.
Operation of the Two-mode hybrid 300 volt battery system and high voltage power electronics will be described. The high voltage disconnect procedure will be explained, as well as how to verify that the high voltage system is disabled. The discharge procedure and jump starting procedure will also be discussed.
Two-mode hybrid supporting systems and self diagnosis logic will also be covered. Voltage conversion components that power various systems will be described. The seminar will conclude with overviews of electric power steering, electric air conditioning compressors, and regenerative braking systems that capture and store energy.

• Identify types, features, and components of Two-mode Hybrid vehicles.
• Identify characteristics, components and system operation of the Two-mode Hybrid 300 volt battery.
• Identify high-voltage warnings and required safety practices when working on Two-mode Hybrid vehicles.

 

This 3 to 4 hour seminar is intended to provide an introduction to vehicle service and safety issues for vehicle owners / students who may lack experience dealing with the vehicle service environment. The topics in this seminar will increase awareness of regular scheduled maintenance, recognizing vehicle problems, and safety concerns. After taking this seminar, students should have the information needed to identify when regular maintenance is necessary. This includes proper tire care, brake system issues, transmission service, frequency of oil changes, and many other relevant topics. Students will also learn how to recognize vehicle service needs including interpreting warning lights, checking fluids, and distinguishing between various brake noises. Extensive use of pass-around components and on-car demonstrations make this a truly, interactive hands on learning session. Students will be presented with the recommended steps for communicating vehicle issues to their technician, as well as steps for ensuring safety on the road to help keep their families protected. Travel tips for the various seasons will also be discussed.
