Outcomes and Objectives

Complete all high-voltage safety tests with 100 percent accuracy and safely work on a High-Voltage Electric Vehicle (HEV).
1. Research applicable vehicle and service information for Hybrid Electric Vehicles, VIN, RPO codes, systems description and operations, service precautions, symptoms, technical service bulletins, safety campaigns, scan tool parameters and definitions, diagnostic trouble codes and diagnostic procedures.
2. Identify the main types of hybrid vehicle technologies and voltage categories.
  1. Safely de-power a hybrid electric vehicle.
  2. Safely perform high-voltage disconnects.
  3. Identify the unique service issues related to HEV high-voltage systems.
  4. Demonstrate the appropriate personal protective equipment (PPE) required.
  5. Explain possible hazards of driving, moving, and lifting a hybrid electric vehicle.
3. Define series, parallel, and series-parallel mechanical/electrical power flow.
4. Identify common hybrid powertrain subsystems.
5. Identify a high-voltage cable or wire by its color.
6. Explain how to use the "one hand rule" for working on electrical circuits.
7. Explain the use of different classes of personal protection equipment (PPE), electrical-safety gloves. Select the proper gloves for working safely on available hybrid vehicles, test gloves for certification and insulation integrity.
8. Describe and perform the different methods for jump starting or jump start assisting on different hybrid vehicles.
9. Verify hazards and proper use of testing equipment, do's and don'ts and the correct use on high-voltage systems.
10. Describe the effects of different levels of electrical currents on the human body.
11. Select proper multimeter category (CAT) and learn how to use on a hybrid electrical system.
12. Demonstrate proficiency in the use of CAT III DMM and perform the necessary systems and components assessments.
13. Verify using insulation tester on high-voltage circuits or components.
14. Identify and verify operation of the high-voltage safety systems, the interlock system, the bus discharge circuit, comparators, voltage and fuel cutoffs, manual/service disconnect and isolation-fault detection systems.
15. Practice Emergency Response. After studying first responder's techniques and safety procedures you will:
  1. Safely de-power a Hybrid electric vehicle.
  2. Safely perform high-voltage disconnects.
  3. Identify the unique service issues related to HEV high-voltage systems.
  4. Demonstrate the appropriate personal protective equipment (PPE) required.
  5. Explain possible hazards of driving, moving, and lifting a Hybrid electric vehicle.
