Electronics Fundamentals: Reading Schematics

Modern vehicles use many electronic controls. Diagnosing faults can be more difficult for technicians who have not had the benefit of training in electronics. This can lead to the replacement of unneeded parts, angry customers, and frustrated technicians. The goal of this training series is to prepare technicians to diagnose and repair vehicle electronic systems successfully. Each training segment will reinforce the concepts taught with exercises and a case study.

The goal of this installment is for technicians to be able to understand wiring schematics and to use them effectively when diagnosing faults.

After completing this training, a technician will:

  • Be able to use a wiring schematic for diagnosing faults
  • Understand the wiring schematic “symbol” library and locate it in service information
  • Use the connector and pin-out information in service information
