This class is a continuation of STA-3803-4. It will concentrate on air/ fuel management strategies as implemented on Advanced Tier platforms. Air/Fuel management has changed drastically in recent years and what we expect to see in fuel trim reactions to systems faults may not apply to today’s vehicles. Special emphasis will be placed on the effects of the downstream exhaust gas sensor on fuel control. Completion of our earlier fuel trim classes is encouraged. Topic discussed will include: • The Air Equation • Air control • Fuel delivery • Feedback devices • Control outside of stoichiometry • Adaptive range and strategy • The effects of secondary control • Key PIDS and analysis

This class coves modern vehicle network operation and how to efficiently diagnose them using common tooling. The overwhelming majority of network related issues do not require decoding of individual packets of data. It is important to understand how a network exchanges information, but a deep dive into the bits. bytes, nibbles and ticks of each network is not needed to repair the vehicle. Knowledge of the network type, the expected voltage levels, and the layout of the network wiring to the modules can provide us with enough information to gain diagnostic direction. At that point, we can use our available tooling to determine the root cause of the problem. Topics Include: • Understanding common automotive networks and where to get help if we don’t understand them • Discuss OE and aftermarket scan tool communication benefits and challenges • Developing a logical diagnostic approach using service information and our own tooling • Understanding diagnosis through communication related case studies

Well over 20 years ago vehicle manufacturers began to utilize a more accurate sensor for the measurement of exhaust gas oxygen concentration. It took many years for the new Wide Band Air Fuel Ration sensor technology to become a mainstream component and now they are failing. This course will provide the knowledge necessary to properly identify and diagnose fuel system issues in systems using these sensors. Diagnosing AFR signals can be tricky and your instructor will show you the best way to obtain a clean usable signal trace so that comparisons with the scan data can be made. If you struggle to properly diagnose these AFR sensors or just want clarification on their operation this is another class you just can't afford to miss.

The Scan Tool Academy series will provide a branching path taking a technician from basic scan tool use, building on a solid foundation, until they achieve power user status. There is ample evidence that basic button pushing classes have not produced the comprehension and comfort that allows a technician to break out of basic functionality. Many shops have invested heavily in scan tools only to have them used primarily as code readers and not much else. This series as a whole does not focus on any one scan tool platform, as our clients own and use many variations of scan tools. We will present scan tool concepts using many of the common scan tool platforms including both multi-line (aftermarket) and manufacturer-specific tools. In Module 1, Practical Application and Analysis, we will: • Introduce a focused, efficient diagnostic routine. • Apply the diagnostic routine to scan tool testing. • Describe how scan tool technology has developed and where it is going. • Explore computer inputs and outputs then compare and contrast what is displayed on a scan tool. • Provide examples of functionality from 10+ scan tool platforms • Using service information to understand the data used to monitor specific vehicle systems, as well as information that may be available through the scan tool. • Cover changes in how Global services work, what has been added and how to use the information to find solutions more efficiently.

Finding the source of fluid leaks is a task every technician faces on a weekly (if not daily) basis. Engineers fighting for every inch of room in the modern vehicle have added some difficulty to this task. “It’s just a leak, right?” But, where is it originating and is there anything else I need to check before the repair? Lighter and smaller components, along with higher mechanical stresses, make correct sealing techniques more critical than ever. Sealing today’s engines require utilization of the latest tools and technology. Learn the techniques that will help you make accurate diagnosis and prevent costly comebacks.

Una prueba de manejo no tiene la intención de aislar fallas que puedan estar causando un síntoma o preocupación. El propósito de una prueba analítica es simplemente recopilar información. Luego, una vez que se ha analizado la información que ha reunido, puede determinar la prueba o las pruebas adecuadas para reducir el problema a un sistema o subsistema de vehículo y, finalmente, diagnosticar con precisión la causa raíz de un problema. Esta clase examinará varios ejemplos de datos de escaneo capturados de vehículos GDI. Esta información evaluará rápidamente la condición del sistema de gestión del motor, verificará el funcionamiento correcto o encontrará pistas que dirigirán las pruebas de intrusión puntuales de manera eficiente. Independientemente de si el problema es impulsado por DTC o por síntomas, un ciclo repetible de conducción de prueba determinará si la causa raíz está relacionada con el aire (VE), relacionada con el combustible o relacionada con la adaptación.
