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 | |
Shaft | Insufficient steering effort (Uneven between LH and RH) | | Do not use the impacted EPS | |
