Steering: Description and Operation
Description
EPS (Electric power steering, Column assist type) system uses an electric motor to assist the steering force and it is an engine operation independent steering system.
EPS control module controls the motor operation according to information received from each sensor.
This results in a more precise and timely control of steering assist than conventional engine-driven hydraulic system.
Components (Torque Sensor, Fail-safe relay, etc.) of the EPS system are located inside the steering column & EPS unit assembly. The steering column & EPS unit assembly must not be disassembled or inspected, just replaced.
Notes With Regard To Diagnosis
1. Do not impact the electronic parts, if they are dropped or impacted, replace them with new ones.
2. Avoid heat and moisture to the electronic parts.
3. Do not contact the connect terminal to avoid deformation and static electricity.
4. Do not impact the motor and torque sensor parts, if they are dropped or impacted, replace them with new ones.
5. The connector should be disconnected or connected with IG OFF.
