All Wheel Drive Technologies
Trainer: Adam Robertson: Instructor – CarQuest Training
Today’s SUVs, sedans and sports coupes are embracing all-wheel drive to improve vehicle handling and, in some cases, make better use of high torque/high horsepower powerplants. Don’t confuse all-wheel drive with four-wheel drive. Although some components are shared between the technologies, all-wheel drive utilizes advanced software and controls to precisely control torque vectoring and aid in the stability of the vehicle. Repairing these vehicles requires not only an understanding of the hardware, but also electronics and control strategies.
Topics in the course include:
- Differences between AWD design vs. 4WD
- The role of software’s role in AWD operation
- Common AWD components and how they operate
- Proper diagnostic testing procedures Analysis of vibration issues

General Motors Stop-Start Technologies
Trainer: Tom Smith: Instructor – CarQuest Training
General Motors introduced the first Stop-Start system on the 2014 Chevy Malibu as standard equipment and now have over 21 models using Stop-Start technologies. Implementing automated stop-start technology in today’s vehicle’s is a cost-effective way to improve fuel economy and reduce emissions. A Stop-Start system operates by shutting off the engine when the vehicle comes to a complete standstill, and automatically restarts the engine when the driver releases the brake pedal. This operating strategy is often utilized in full hybrid-electric vehicles that have powerful electric systems but is also becoming more popular in non-hybrid vehicles that use traditional starter/battery configurations.
Topics include:
- Dual battery and control methods used to isolate the electrical systems during Autostop/Start
- Robust starter motor technologies-Dual Tandem Starter design and operation
- Capacitor and DC-DC (Transformer) Control Stop-Start systems
- Common components found on each system
- Stop-Start input and output control logic
- DTC descriptors and scan tool diagnostic evaluation methods
- Important best service practices to handle working on GM vehicles equipped with Stop-Start systems.
ADAS Best Practices

Pulse Width Modulation and 3-Phase Controls:
Diagnosing Pulse Width Modulation for Power, Control and Sensing Circuits
Trainer: Gary Smith: DiagNation (sponsored by WorldPac)
Note: This is NOT a Hybrid/EV class!
In this class, we will discuss Pulse Width Modulation (PWM) theory and specifically how it applies to various automotive systems. The class will flow theory to scanner and scope analysis during diagnosis of several recent case studies.
- What is Pulse Width Modulation and How Does It Work? Concepts and Theory
- Understand the differences in use and applications of PWM in power, control and Sensing circuits in BMW and other European vehicle platforms.
- Brief explanation of PWM motor encoding for sensing and motor control applications.
- Introduction to BMW Valvetronic Motor and DME Driver Analysis, 3-phase Motors
- Introduction to 3-Phase AC/DC (Non-ground) Fuel Pumps and Controls in BMW Vehicles
Who should attend?
Anyone seeking a deeper understanding of the concepts of PWM motor control, AC current flow and motor controls from DC drivers. Also, those who seek to understand their scanner and scope data in these systems beyond just viewing the analog signals.
AC current is in play in multiple modern automotive sub-systems and of course is the main motivator behind hybrid and EV platforms. See how AC is managed in a DC digital world and how it affects your diagnostics.
Network Nightmares: Solving the Diagnostic Distress
A real-world, hands-on approach to successful and productive network diagnostics
Trainer: Gary Smith & Adam Robertson: DiagNation (sponsored by WorldPac)
Note: Full 8-hour DAY CLASS!
There is no doubt that data communications and network issues are amongst the most difficult, time consuming and costly diagnostics that we encounter. Factory scan tools offer expanded testing techniques that are manufacturer specific, but even those dedicated software platforms are not enough to accurately diagnose these problems in many cases.
Network problems fall into several categories: Codes and multiple communication DTCs, module errors, vehicle wiring and component faults, intermittent ugliness and more. This class is designed to provide the attendee with unique diagnostic strategy and new approaches toward network and communication issues. In this class, we share the road maps that we have learned and developed over many years of study and application.
Topics will include:
Network Theory, Configuration and Components
Construction and Theory of Operation of the Various Sections of CAN we Analyze in the Physical Layer
- Single and dual wire, ethernet, fiber optic, wireless and the rules that make them work.
- Network “wake-up” strategies and wakeup waveform analysis.
- How the protocol language (actually) means something to us in the waveform.
- The terminated network bus lines and diagnosing this quickly and accurately.
Learn the Physical Rules that Makes any Network Function, Waveform Interpretation and Analysis:
Vehicle communications networks are simply radios, broadcasting and receiving via a balanced antenna (The twisted pair bus lines). Learn how viewing and testing communications faults by segregating the circuit into transceiver and antenna can help demystify the technology and help you target your next step accurately.
Blend the theory parts (Predictable and provable by Physical Laws) with actual waveform analysis and connect the dots in your approach and on-car strategy for network diagnostics. Terminated bus lines and the CAN node’s operation are covered and how this directly relates to useful interpretation of your scope waveform analysis. Knowledge is power.
- Waveform interpretation, serial decoding, math channels, XY views, masks, alarms and more
- Each topic will be backed up with real case studies to re-enforce the strategies used.
- Network topology designs and their operational strategies
