CAUTION:

Cautions to be taken when handling the MDPS (Motor Driven Power Steering)

  • Failure occurs due to internal damage because of the drop of and shock and excessive external force on the new partial component.

    → Be cautious of shock on the partial component and replace the damaged part (due to drop, etc.) with a new one.

  • When fastening the steering, excessive impact may result in twisting the center point of the torque sensor.
  • When removing/installing the connector the wiring may be damaged (deformed) by excessive external force.
  • Be cautious when storing and replacing the partial components under the abnormal temperature and humidity conditions.
