Noise/malfunction Repair Procedures

3 Noise/malfunction Inspection

Symptom	Fault description and inspection method	Countermeasure
Noise/rattle	Noise generated near the MDPS column & housing. Remove the surrounding parts and check whether the same noise occurs.	Replace the partial component of the column and housing Replace the motor if the noise occurs
Noise/rattle	Check the handle and surrounding fastening parts. Check DAB wiring arrangement, DAB, clock spring, multi-function switch, etc.	Check the noise of the relevant part Perform a separate inspection.
	2. Check where the C-MDPS is installed. Loosen the cowl fastening bolt and reassemble. (including the through bolt fixing the lower part of the C-MDPS)	Check the installation of the cowl
	3. Check the fastening area of the universal joint bolt. Completely remove the universal joint and check whether the noise occurs after the reinstallation.	Fasten with a new bolt if the universal joint bolt is worn
	4. Check free playing area of the column when steering while the vehicle is stopped. Check the main wiring connected to the MDPS and column/interference around the shroud/friction	Keep spaces between the surrounding parts Check freeplay around the wiring and column and inspect interference.

4 Cautions to be taken while servicing

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.
