Activities in this Lesson

  • Materials needed:

    • Whiteboard:  (Write the following)  Service and repair information
    • Worksheet:  Service Information Basics
    • PowerPoint presentation:  Vehicle Service Information 
    • Wiring diagram:  Any one you may have handy


    This will be a short introduction to the topic for the lesson.  Students will be asked to share some scenarios of what might happen if correct service information wasn't used when performing vehicle service and repairs.  Then the instructor will lead the students through a review of the worksheet Service Information Basics  they filled in at the start of class.


    Instructor Note:  As students walk in, have them pick up the worksheet Service Information Basics  and start working on it while you're taking roll.  This is an ungraded worksheet that will be used for discussion.  It will help get the students settled and in tune with the topic for the lesson.

    (Slide #1):  Instructor:  " 'Fixed right first time' starts with good service information.  That will be our theme for the day."

    (Slide #2):  Instructor:  "Correct vehicle repair depends heavily on good service and repair information.  This slide shows how our lesson will play out."

    Instructor:  "Most of you know at least the basics of how cars work.  But there are certain systems on the vehicle that require more than just a basic knowledge.  You may need certain bearing clearance specifications.  Or maybe you're troubleshooting a condition that has electronics and wiring involved that requires wiring diagram usage.  How do you approach a situation like that?"

    Instructor:  "Additionally, if you don't have good service information, it could mean the difference between a good or bad repair job.  I'd like to hear from a few of you:  Give some examples of using incorrect vehicle specifications or information and what might be the outcome.   (Lead the class in this discussion by asking for volunteers to answer this question:  You are looking for examples such as wrong oil change information, incorrect lubricants, wrong tightening torque, wrong vehicle year, etc.).

    Instructor:  "Based on our discussion, I think we all understand the importance of accurate service information.  When service information isn't looked up and used properly, the ultimate outcome will likely be negative.  The importance of correct and appropriate service and repair information can't be emphasized enough.  It could have an effect on other related vehicle systems.  It will most likely affect customer satisfaction relations with the technician or the business.  It could even lead to legal risk and possible litigation.  Yes, maybe worst case scenario.  But it's happened!"

     Instructor:   "So at the end of today's lesson, you will understand how to retrieve and interpret vehicle service information specific to the vehicle you're working on.  This will help to ensure "fixed right the first time."

    Instructor:  Any questions to this point?

    Instructor:  "You were given a worksheet when you walked into class today: Service Information Basics.  You were asked to match up words and descriptions.  With that sheet in front of you, we'll go through it as a basic foundation for our lesson today.

    Instructor note:  At this time, lead the students through the worksheet with a short discussion for each of the answers.

    Instructor:  "So with that short background, we're going to move on.  Today this lesson will equip you with the knowledge of how to retrieve and use service information in both electronic and hard-copy format.  You'll understand the importance of information/specifications look-up and use as pertains to a vehicle fixed right the first time. 

    Instructor:  (Hold up a wiring diagram):  "You'll also have opportunity to use a vehicle wiring diagram including interpreting symbols.  Finally, we'll give you time to trace a circuit using a wiring diagram.  You'll be on your way to being an expert!"

  • Materials needed:

    • Powerpoint Presentation:  Vehicle Service Information
    • Student Worksheet:  Vehicle Service Information
    • Vehicle Owner's Manual
    • Vehicle Service Manual (paper-copy)


    During this part of the lesson, the Instructor will use a PowerPoint presentation to guide students through the lecture. The various types of vehicle service and repair information will be discussed and illustrated.   The students will follow along using a related worksheet Vehicle Service Information.  Students will fill in blanks on the worksheet that goes along with the lecture.


    Instructor:  Hand out student worksheet Vehicle Service Information

    (Begin PowerPoint presentation here)

    (Slide #3):  Instructor:  "Our discussion on vehicle service information will begin with the vehicle identification number, or known as the 'VIN'.  As the slide shows, the VIN may be located in a number of places.  The VIN contains vehicle build date, place of manufacture, engine type, and information about some of the vehicle's accessories."

    (Slide #4):  Instructor:  "Engine and emissions information is contained under the hood.  There's a label that provides such information as emissions control devices, OBD classification, engine size, vacuum hose routing, and other useful information. This label is called the Vehicle Emissions Control Information label.  Vehicles produced since 1972 are equipped with this label."

    (Slide #5):  Instructor:  " Every vehicle engine is marked with an engine number by the factory.  The engine number includes coded information, which can be decoded to reveal information such as year of manufacture, country of manufacture, and engine type.  Engine ID numbers are usually stamped in the cylinder block." 

    Vehicle service information sources

    Slide #6):  Instructor:  "Now we'll take a look at the various vehicle service information sources.  One helpful source of vehicle service information is, believe it or not, the vehicle Owner's Manual.  The Owner’s Manual contains information for new owner’s ‘first-drive’.  It is often helpful for technicians verifying customer complaints on systems that may be functioning normally.  And it also contains re programming information for certain late-model vehicle electronic systems."

    (Slide #7)  Instructor:  "Now we'll discuss the various technical service and repair manuals and information available to vehicle owners and repair technicians.  The first of these are the Service Manuals created by the Manufacturer.  These Service Manuals are specific to a vehicle and are designed to be used by technicians in a dealership."

    (Slide #8):  Instructor:  "Next we have generic Service Manuals:  These cover all makes of either import or domestic vehicles.  Two major brands are Chilton and Haynes.  They're not quite as detailed as the factory service manual but are good for the 'Do-it-Yourselfer'.

    Slide #9):  Instructor:  "Next we have Professional trade magazines.  These are intended for the career professional technician.  Motor Magazine, Motor Age, ImportCar are a few published which often include information from the latest factory Technical Service Bulletins (TSB's)."

    Slide #10):  Instructor:  "Another version of Service Manual is electronic.  This CD-ROM or DVD format allows a great deal of service and repair information to be stored electronically.  Saves trees, also!"

    (Slide #11):  Instructor:  "Finally, we have available service and repair information downloadable from the internet.  This web-based information is available in pdf format."

    (Slide #12):  Instructor:  "Next we have Technical Service Bulletins, or TSB's.  TSB's usually contain  field service and repair information that isn't contained in the factory service manual.  Service campaigns and recall bulletins are also sent out in TSB's."

    (Slide #13):  Instructor:  "Finally, we have Hot-Line services.  These groups use service and repair information contained in vast data bases to provide information and help for unique service and repair needs that may not be covered elsewhere."
