Introduction/Context / This lesson will instruct the student on how to access and use service information to perform step-by-step (troubleshooting) diagnosis. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in an Automotive Repair Facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to an automobile accident or create customer satisfaction issues.

Content/Presentation/Demonstration Outline
Inform students that there are four basic types of diagnostic charts. These are tree, block, illustrated, and component location charts.
Explain to students that a tree diagnosis chart provides a logical sequence for what should be inspected or tested when trying to solve a repair problem. For instance, if a horn will not work, the top of the tree chart may tell them to check the horn's fuse. Then, if the fuse is good, it may have them measure the voltage going to the horn. Tell students they can work their way down the "tree" until the problem is fixed.
Inform students that a block diagnosis chart lists conditions, causes, and corrections in columns. Let them know that the most common cause is the top listing. For example, if an engine overheats, loss of coolant appears at the top of the "causes" column. Check the coolant level. If this is the problem, fill the radiator and check for leaks. If the coolant level is OK, go to the next listing.
Teach students that an illustrated diagnosis chart uses pictures, symbols, and words to guide them through a sequence of tests. If an engine oil pressure gauge shows low oil pressure, for example, the chart shows them exactly what to do, step by step, until the problem is corrected. This type of diagnosis chart not only tells them what to do, but it shows them how to do it.
Instruct students that a component location chart shows where various parts are located on the vehicle. This type of chart is often used for the engine compartment. Explain that the chart helps locate the numerous sensors, relays, fuses, and other components housed in this area.
INSTRUCT STUDENTS THAT TO USE A SERVICE MANUAL, FOLLOW THESE BASIC STEPS TO ACCESS SERVICE INFORMATION: 1. Locate the proper service manual. Some manuals come in sets or volumes that cover different repair areas. Others cover all subjects and all car makes. If you are working on engines, find the manual that gives the most information for the type of engine being serviced. 2. Turn to the table of contents or the index to quickly find the needed information. Never thumb through a manual looking for a subject. 3. Use the page listings given at the beginning of each repair section. Most manuals have a small table of contents at the beginning of each section. 4. Read the procedures carefully. A service manual gives highly detailed instructions. They must not overlook any step or the repair may fail. 5. Study the manual illustrations closely. The pictures in a service manual contain essential information. They cover special tools, procedures, torque values, and other data essential to the repair.
Let students know that most repair information today comes in a COMPUTER BASED FORMAT. Computer-based service data is information stored or retrieved electronically using a personal computer. Explain that automotive service information can be stored on computer's hard drive, CD-ROMs, DVDs, or a computer network. A computer can find and retrieve this information much more quickly than a technician paging through a service manual. Modern repair shops are using computer based service data everyday.
Inform students that computer systems can be used to store and access a variety of service-related information, including: 1. Repair procedures. 2. Repair illustrations. 3. Part prices. 4. Labor times. 5. Safety rules. 6. Troubleshooting charts. 7. Diagnostic trouble code charts. 8. Business software for billing and ordering parts.
Applications/Practice
Evaluation and feedback Prior to Testing or Lab Work
STUDENT ASSESSMENT:(Assess student progress with performance criteria.)
IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)
REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)
