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 | |
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 |
