This guide will provide in-depth information about the diagnosis and repair of each system that is involved in engine performance.  The book is divided into chapters that focus on each system individually to help you truly absorb the information and fully prepare you for the exam.  Take AVI’s practice test to see which sections of the book you need to focus on.  Base on your quiz results, AVI has supplemental training programs to assist you with the sections you need help in so you can be confident that you will leave the ASE test center with A8 certification.

Dave will start with an explanation of CAN data, how it works and why it is necessary.  He will show you how to identify vehicles that are equipped with CAN and how the system differs from others.  Dave provides schematics to help you learn how the system works.

This program explains functional diagnostics and defines buzzwords such as “Virtual Networks,” “Learned Nodes” and “Buddy Systems.”  Dave defines code suffixes and system numbers and shows you how they can help with diagnostics.  He also explains what a “CANDI” (Controller Area Network Diagnostic Interface) module is used for.  Dave packs a huge amount of information into this 1.25 hour seminar.

In order to pass the ASE A6 or L1 Certification exam it is essential that you understand how to read and interpret schematic diagrams.  Instructor Peter Orlando is an expert at electronics and in this program he will help you comprehend electrical schematics using real world case studies.

Reading schematics involves understanding the meaning of different symbols.  This class will explain you what the symbols demonstrate and whether all manufacturers use the same symbols.  Peter shows you how to find components and connectors with location codes. He explains how to trace circuits using OEM and after-market schematics and provides a 3-step power diagnostic process.

You will learn the difference between an open, a short and a ground.  Peter will also explain the difference between a circuit diagram, a schematic diagram and a wiring diagram and why you should ALWAYS know which way the current is flowing.  If you want to pass the A6 or L1 exam, this class is a must.

MUST KNOW Information

• The difference between an open, a short & a ground
• The difference between a circuit diagram, a schematic diagram & a wiring diagram
• ALWAYS know which way the current is flowing

Craig Van Batenburg of ACDC helps you save valuable time by explaining how to put 2 trip and 3 trip monitors into one single monitor. He also goes over the EVAP monitor and the O2 sensor monitor with Zirconia and Heated O2. This class will show you how Honda catalyst monitors are different and how their sensors work and gives you a Great tip on using the injector pulse width, especially on those cars with NO-Codes.

• How to use your scanner data to figure intake vacuum
• Fuel system monitor, what the PCM looks at and how Honda uses 02 sensors for more than just fuel monitoring
• Factory & generic scanner testing data-what to look out for
  Manual covers 1996-2005 Honda and Acura OBD II Models with help sections, common failure problems, suspension & brakes

Most Ford vehicles are equipped with Electronic Returnless Fuel (ERF) systems, which are tough to diagnose.  You will also need to be familiar with this type of system to become ASE A8 or L1 Certified.   AVI and Jim Wilson will give you the information you need to know to pass the fuel system portion of the A8 exam and diagnose and repair Ford ERF systems.

In this program Jim explains why ERF systems are tough to diagnose and why conventional fuel system testing does not work. He covers the components, how to identify ERF systems, the different types of ERF systems, how they work and how to diagnose them.

This course explains how to check the fuel pump duty cycle command and how to use the duty cycle to determine fuel pressure. John also shows you how to test the pressure transducer and how to locate and test the fuel pump driver module. This course is full of great tips to help you diagnose ERF systems.

• Hands-on testing using the scanner and labscope
• Why you can’t ramp the fuel pump
