The aim of this chapter is to help you better understand what you stand to gain by acquiring an Automotive Service Excellence certificate.

Welcome to the first chapter of the Manual Drive Train and Axles study guide. The Manual Drive Train and Axle certification test is the third test in the series of tests provided by the Automotive Service Excellence organization. And the objectives of this introductory chapter include the following:

THE OBJECTIVES This chapter introduces the background behind the Automotive Service Excellence test, its history and its benefits to auto-repair technicians. Through the course of this chapter you will learn about the following: •

Why the Automotive Service Excellence program was formed and why it is important to every auto-repair technician.

•

The importance of getting an Automotive Service Excellence certification for auto-repair technicians and,

•

The benefits of having certified auto-repair technicians for light truck and automobile repair business or shops.

The development of more vehicles in the nineteen-sixties and the increased purchasing power of Americans after the great depression led to an increase in the number of 1

vehicle owners across the country. And with this increase in automobile ownership came a problem and the problem was how to efficiently diagnose, service and repair faulty automobiles. As a solution to this problem, hundreds of auto-repair technicians popped up in every nook and cranny of the United States offering repair services. But in three out of five cases, the auto-repair technician was out of his depth, the word ‘his’ is used here because auto-repair technicians of that time were mostly men.

The unprofessionalism in the auto-repair field led to thousands of complaints and a need to bring sanity to the auto-repair industry and this was when the idea behind the Automotive Service Excellence organization was formed. In nineteen seventy – two, a couple of experienced auto-repair technicians came together to form the National Institute of Automotive Service Excellence organization. The National Institute of Automotive Service Excellence body was created as a non-profit organization with the aim of providing certification tests to auto-repair technicians. And with the passage of time, the organization’s name was shortened to Automotive Service Excellence and this name has stuck till date.

Since then, the certification tests offered by the Automotive Certification excellence organization have become the standard for auto-repair technicians looking to legitimize their abilities. Today, you can now sit for the Automotive Service Excellence certification tests in more than seven hundred locations across the country.

MANUAL DRIVE TRAIN AND AXLES TEST A-THREE (A3) The Manual Drive Train and Axles test was developed with the aim of testing your understanding of manual drive train components as well as how they operate in optimal conditions. The test was also developed to check your ability to diagnose the common and not so common problems that relate to modern drive trains and axles. The test will also take into consideration the different equipment and tools needed to diagnose issues with a manual drive train.

The task of servicing a manual drive train not functioning at its best is also covered in details in the third test under the Automobiles and Light Truck test series. Now, in order for a candidate such as you to be successful in taking the test, it is important that you have an understanding of the testing procedure used by the Automotive Service Excellence organization. This is due to the fact that having some understanding of the type of questions to expect will get you better prepared for taking the test. Therefore, the next paragraphs will introduce the question formats used by the Automotive Service Excellence program in conducting its series of tests.

QUESTION FORMATS USED IN THE AUTOMOTIVE SERVICE EXCELLENCE CERTIFICATION PROGRAM Every certification test in the Automotive Service Excellence makes use of the same testing and question format. And the format the Automotive Service Excellence organization makes use of the multiple choice question formats. Multiple choice questions are those questions that are asked or stated and are accompanied by objective answer choices which you are expected to select the correct answer from. Therefore, the Automotive Service Excellence multiple choice question formats includes a question statement and four objective answers titled as A, B, C, and D.

11

LEAST-LIKELY QUESTION FORMAT Finally, we have the LEAST likely format to explore. The Automotive Service Excellence organization makes use of LEAST likely questions as a counterbalance to the most likely question format. And with questions in this format, you are expected to choose the least likely cause of a specific problem from the answer options provided in the exam booklet.

It is also worth noting that the task of identifying questions in this format has been simplified by the Automotive Service Excellence organization. This process is simplified due to the fact that the word ‘LEAST’ will be written in capital letters to highlight the fact that you are about to provide an answer to a LEAST-likely question. A good example of a LEAST likely question is the following: A faulty vehicle is brought into the shop for repairs. What is the LEAST likely diagnostic procedure to start with? a. Listening to the customer’s complaint b. Checking the battery for damage c. Uninstalling the crankshaft d. Listening to the sounds coming from the vehicle.

The answer is C. Removing the engine and uninstalling the crankshaft or any other component is the LEAST likely first step to take when inspecting a car for damage. Here, you can see that LEAST likely questions are a bit easier than some of the other question formats and the word LEAST has been capitalized to help you know the type of question you are tackling.
