Repair procedures ➤

MDPS Motor ➤

MDPS Control Unit

- Replacement

1.Disconnect the battery negative cable from the battery and then wait for at least 30 seconds.

2.Remove the crash pad lower panel.(Refer to Body - "Crash Pad Lower Panel")

3.Disconnect MDPS ECU connector.

4.Loosen the MDPS ECU bracket bolts and then remove the MDPS ECU.

ASP Calibration

– Steering- angle sensor detects the steering angle and steering angle speed. Steering angle and steering angle speed are used for steering wheel damping and return controls in addition to providing assistance torque.

• You can use a scan tool to (GDS) check if the battery voltage is proper before perform the "ASP Calibration".

• Make sure that no connector engaged to the vehicle or scan tool is disconnected during the "ASP Calibration".

• Once the "ASP Calibration" is complete, turn off the IG switch and wait for 10 seconds or more before starting the engine to check the operation.

1.Connect self - diagnosis connector (16pins) located in the lower of driver side crash pad to self - diagnosis device.

2.Turn the self - diagnosis device after key is ON.

3.Turn the steering wheel to straight ahead position.

4.After Selecting the "vehicle model" and "system", select the "ASP Calibration" on GDS vehicle selection screen.

EPS Type Recognition

• When missing the EPS Type Recognition, occure a problem with motor driven power steering performance.

• You can use a scan tool to (GDS) check if the battery voltage is proper before perform the "EPS Type Recognition".

• Make sure that no connector engaged to the vehicle or scan tool is disconnected during the "EPS Type Recognition".

• Once the "EPS Type Recognition" is complete, turn off the IG switch and wait for 10 seconds or more before starting the engine to check the operation.

1.Connect self - diagnosis connector (16pins) located in the lower of driver side crash pad to self - diagnosis device.

2.Turn the self - diagnosis device after key is ON.

3.Turn the steering wheel to straight ahead position.

4.After Selecting the "vehicle model" and "system", select the "EPS Type Recognition" on GDS vehicle selection screen.

5.Remove the DTC.

6.Turn off the IG switch and wait for 10 seconds or more before starting the engine. And then make sure that MDPS works properly.

MDPS Column and Housing

- Removal

1.Remove the MDPS assembly.(Refer to Steering System - "MDPS Assembly")

2.Remove the MDPS control unit.(Refer to Steering System - "MDPS Control Unit")

3.Remove the MDPS motor.(Refer to Steering System - "MDPS Motor")

1.Install in the reverse order of removal.

2.Perform "set the steering feel torque to zero" using the GDS.

3.Conduct the "ASP Calibration" by GDS.(Refer to MDPS Assembly - "Diagnosis with GDS")

4.Conduct the "EPS Type Recognition" by GDS.(Refer to MDPS Assembly - "Diagnosis with GDS")

5.Check the DTC.

6.Turn off the IGN switch and wait for 20 seconds or more. Then check the operation after starting the engine.
