Electric Power Steering

Electric Power Steering is Lesson 5 of Voltzs Module 28, ABS, Stability, Steering, Suspension & Tyre Electronics. This automotive diagnostic lesson explains Column/rack motors, torque sensors, high current and module supplies. It is designed to show technicians, apprentices, auto electricians and serious DIY learners not only what the system does, but how to reason through it: what to inspect first, which tool or measurement is appropriate, where a test should be made when safe, what the result can prove, what it cannot prove, and what the next diagnostic step should be. By the end, the learner should be able to Diagnose EPAS supply/network/sensor faults with high-current awareness. Voltzs builds this knowledge in sequence from Lesson 4: Stability Control Sensors and prepares the learner for Lesson 6: Electronic Parking Brake. Vehicle-specific values, pinouts and procedures vary, so the full lesson distinguishes universal electrical principles from specifications that must be checked against reliable manufacturer information.
