EPS (Electronic 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 the each sensor and CAN (Controller Area Network).
|
- |
Resulting in a more precise and timely control of steering assist
than conventional engine-driven hydraulic systems.Components (Steering
Angle Sensor, Torque Sensor, Fail-safe relay, etc.) of the EPS system
are located inside the steering column & EPS unit assembly must not
be disassemble to inspect or replace them.

Trouble factor |
Check item |
Trouble symtom |
Explanation |
Note |
Drop, impact, and overload |
Motor |
Abnormal noise |
- Visable or unvisable damage can occur.The steering wheel could
pull to one side by using the dropped parts.- Precise parts of motor/ECU
are sensitive to vibration and impact.- Overload can cause unexpected damage |
- Do not use the impacted EPS.- Do not overload each parts. |
ECU |
Circuit damage- Wrong welding point- Broken PCB- Damaged precise
parts |
|||
Torque sensor |
Insufficient steering effort |
Overload to INPUT shaft can cause malfunction of the torque
sensor |
- Do not impact the connecting parts (When inserting and torquing)-
Use the specified tool to remove the steering wheel. (Do not hammer on it)-
Do not use the impacted EPS |
|
Angle sensor |
Insufficient steering effort (Uneven between LH and RH) |
|
Do not use the impacted EPS |
|
Pull/Dent |
Harness |
- Malfunction-impossible power operation- Malfunction of EPS |
Disconnection between harness connecting portion and harness |
Do not overload the harness |
Abnormal storage temperature |
Motor/ECU |
Abnormal steering effort by improper operation of the motor/ECU |
- Waterproof at the normal condition- Even a little moisture
can cause malfunction of the precise parts of the motor/ECU |
- Keep the normal temperature and proper moisture, while storaging-
Avoid drowning |
