Title: Demonstrate knowledge of electric power-steering (EPS) system operation.
Course: Automotive Technology II (MLR 3-Year Program) (20104-IIA) > Section: SUSPENSION AND STEERING: Steering Systems

Demonstration should include

- how an EPS system operates
- the components and functionality of an EPS
- advantages, disadvantages, and diagnostic considerations.

Process/Skill Questions:

- What are the differences between hydraulic and EPS systems?
- How does one use a scan tool to retrieve diagnostic trouble codes (DTCs) from the EPS control module?
- What are some common symptoms of EPS system issues, and how would one identify the root causes?
- What steps should one take to verify whether an EPS issue is electrical (e.g., wiring, motor) or mechanical (e.g., steering rack)?
- What sensors does the EPS system use?
- What speeds does the EPS system use to adjust the amount of assistance the driver receives?
