Vehicle Service Info and Diagnostic Process

Chapter 6 Vehicle Service Information

Lesson Objectives

  • Utilize information systems for vehicle service information.

  • Locate and identify vehicle identification number (VIN) information.

  • Interpret other vehicle information labels.

Introduction to Vehicle Service Information

  • Modern vehicles are complex with various makes and models and may have computer-controlled systems.

  • Understanding how to research and apply service information is critical for proper vehicle maintenance.

Types of Vehicle Information

  • Vehicle Identification Plates: Display essential details about the vehicle.

  • Owner's Manuals: Comprehensive information about operations, maintenance, and specifications.

  • Shop Manuals: In-depth guides for repair procedures and specifications.

  • Repair Orders: Documents detailing service requests and maintenance history.

  • Service and Parts Programs: Electronic databases for part numbers and service guidelines.

  • Technical Service Bulletins (TSBs): Updates regarding vehicle issues and repairs.

Using Information Systems

  • Service Manuals: Provide detailed vehicle repair instructions.

  • Online Resources: Increasingly popular due to frequent updates and broad accessibility.

    • Aftermarket Service Manuals: Often less detailed and more general for ranges of models

  • Service Information Programs: Computer applications that allow technicians to search for specific vehicle repair details efficiently.

    • Utilize keywords and selections to narrow searches, providing text and visual aids.

  • Technical Service Bulletins (TSBs): Include step-by-step guidelines for identifying faults and effective repairs.

  • Service Campaigns and Recalls: Address safety issues with mandatory or voluntary repairs; manufacturers cover the cost; verify recalls by VIN.

  • Labor Guides: Estimate labor times for repairs, aiding in job estimates; utilize average times but may include allowances for various factors.

  • Parts Programs: Electronic catalogs that assist in identifying vehicle parts; all vehicle makes and models have unique part numbers.

Vehicle Service Maintenance

Normal Service Table Example

  • Lists maintenance intervals and procedures for various vehicle components at different mileage milestones (e.g., air filters, spark plugs, tires).

Vehicle Identification Number (VIN)

  • Definition: A unique 17-character serial number that identifies individual vehicles and provides a service history.

  • VIN Locations: Found in multiple places on the vehicle.

  • Significance: Helps deter auto theft and assists in determining production details.

Decoding VINs

  • North American VIN System: Follows ISO Standard 3779. Each character or sequence denotes specific vehicle attributes, including country, make, model year, and assembly location.

Other Vehicle Information Labels

  • **Essential Information: ** Tire pressures, weight capacity, emissions requirements, and fluid types.

    • VECI Label: Includes details on the engine family, model year, and emissions schematic.

    • VSC Label: Contains basic vehicle info, such as manufacturing date, weight ratings, and recommended tire specifications.

Summary Questions

  1. Owner’s manuals provide important vehicle information, including maintenance details and operational guidelines.

  2. Service manuals organize information by systems (e.g., engine, electrical).

  3. Removal time for specialized tasks (like aftermarket wheel locks) is classified under different time categories (standard, additional, etc.).

Conclusion Questions

  • Knowledge of VIN importance includes not only vehicle identification but also service history, engine identification, and recall information.

  • The structure of documentation, such as repair orders, plays a vital role in service history and warranty claims.

  • A vehicle's service history influences its resale value, reflecting regular maintenance and repair.

Chapter 7 Repair Orders, Strategy-Based Diagnosis, and the 3 Cs

Lesson Objectives

  • Mastery of completing repair orders.

  • Employ strategy-based diagnosis to pinpoint faults.

  • Document repairs using the 3 Cs (Concern, Cause, Correction).

Introduction

  • Accurate documentation through repair orders is essential for tracking maintenance, service details, and customer concerns.

Completing a Repair Order

  • Components of a Repair Order: Includes customer and vehicle details, the customer concern, and the summary of service. Maintains transparency and accountability.

  • Key Elements: Shop information, customer contact details, VIN, authorization signatures, history, and labor/part information.

Strategy-Based Diagnosis

  • Steps of Strategy-Based Diagnosis: 1. Verify the concern; 2. Research possible faults; 3. Focused testing; 4. Perform the repair; 5. Verify the repair.

  • Document each step clearly to maintain organized service records and enhance diagnosis efficiency.

Using the 3 Cs in Documentation

  • Concern: Document the customer’s understanding of the problem.

  • Cause: Identify the underlying issue causing the concern through thorough investigation.

  • Correction: Specify the process and parts used to rectify the problem.

Conclusion Questions

  • The importance of utilizing a structured approach (3 Cs) in documenting repairs to ensure clear communication and maintain legal standards on repair orders.
