Introduction To Automotive TechnologyACKNOWLEDGMENTSThe 2006 revision of Introduction to Automotive Technology represents theInstructional Materials Laboratory’s commitment to the continual improvementof the Automotive Technology Curriculum. Introduction to Automotive Technologyis the first in the nine-module series. The other modules are as follows:Module 2Module 3Module 3Module 3Module 4Module 5Module 6Module 7Module 8Module 9Electrical SystemsEngine Performance, Section 1: Ignition SystemsEngine Performance, Section 2: Fuel and Exhaust SystemsEngine Performance, Section 3: Emission Control SystemsEngine RepairSteering and Suspension SystemsBrakesManual Drive Train and AxlesAutomatic Transmissions and TransaxlesHeating and Air ConditioningAll modules are based on the National Automotive Technicians EducationFoundation (NATEF) task list. For years the National Institute for AutomotiveService Excellence (ASE) has set the professional standards for automotivetechnicians. A strong NATEF orientation makes the nine curriculum guides aneffective tool for preparing students to enter the technologically advanced field ofautomotive technology.IML gratefully acknowledges the important contribution of the advisorycommittee:Roger Donovan, Illinois Central College, East Peoria, ILKen Estes, Grand River Technical School, Chillicothe, MORobin Ferguson, Kirksville Vocational Technical School, Kirksville, MOSam Jeanrenaud, Lee’s Summit, MOKeith Kendrick, John A.

Introduction To Automotive TechnologyCOMPONENTSI.Objectives — Each unit is based on objectives that state the measurableunit and specific behavioral or performance objectives that the student isexpected to achieve. Because the objectives of the unit provide directionfor the teaching-learning process, the teacher and student need a commonunderstanding of the intent of the objectives.II.Information Sheets — Presented in outline format, the information sheetsprovide content essential for meeting the cognitive (knowledge) objectivesin the unit. The student should study the information sheets before anyclass discussion or completion of the assignment sheets. The correspondingStudent Reference page numbers appear in the upper corner of theInstructor Guide.III.Assignment Sheets — The assignment sheets allow the student to respondto cognitive questions in writing.IV.Job Sheets — The job sheets are designed to guide the student throughvarious key tasks and provide a means for the instructor to evaluate astudent’s performance of the task.V.Unit Tests — The unit tests evaluate the student’s knowledge of thematerial.VI.Student Workbook and Student Test Packet Tracking Sheets — Theseprovide the instructor with an effective way to track student progress onthe assignment sheets, job sheets, and unit tests.vii

Brakes Electrical/electrical systems Engine performance Suspension and steering Automatic transmission and transaxle Engine repair Heating and air conditioningS

Automotive Technology b.2.C.Manual drive train and axlesTo be certified, technicians must have at least 2 years ofexperience and pass an ASE written examination. Theymust retake the exam every 5 years to maintain theircertification.The National Automotive Technicians Education Foundation(NATEF), an arm of ASE, reviews training programs to ensurethey are meeting ASE standards and staying up-to-date withthe continuously changing automotive technology and repairmethods.a.Training programs request the review process on avoluntary basis. If a program passes the review, NATEFrecommends it to ASE for certification. Programs must bereviewed again every 5 years to be recertified.b.In ASE’s automobile specialty, training programs can becertified in the eight areas listed in 1a.To stay current with changes and advancements in the field,automotive technicians will need to attend training classesthroughout their careers. Technicians may receive training at theirworkplace or may need to attend classes at a technical school orcollege.S

Introduction To Automotive TechnologyIII.IV.V.Job prospects in the automotive technology fieldA.Prospects are very good for individuals with training and skills indiagnosis, problem solving, electronics, and mathematics. Knowledgein electronics has become crucial because most vehicle concernsinvolve working with or analyzing the electrical system. According tothe Alliance of Automobile Manufacturers, “electronics now controlmore than 86% of all systems in a typical vehicle.”B.Many employers in the industry have reported that there is a shortageof automotive technicians and they have difficulty hiring individualswith education and experience in the areas desired.C.According to the Occupational Outlook Handbook,
