Work Procedure

After replacing the ADAS control unit 2 and after replacing or removing the following steering components, the steering torque calibration is necessary to operate the system normally.

• Steering wheel
• Combination switch (spiral cable)
• Steering angle sensor
• Steering column assembly
• Steering gear assembly

NOTE: Follow the CONSULT when performing Steering Torque Calibration. (Steering Torque Calibration cannot be performed without CONSULT).

Work Procedure (Preparation) 

1. PERFORM SELF-DIAGNOSIS 
   1. Turn ignition switch ON.
   2. Perform self-diagnosis of "ICC/ADAS 2".
   3. Check if any DTC is detected.

   Is any DTC detected?

   YES>>

   Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to DTC Index .

   NO>>

   GO TO 2.

2. PREPARATION BEFORE STEERING TORQUE CALIBRATION 
   1. Perform pre-inspection for diagnosis. Refer to Work Procedure .
   2. Place the car on a level surface.
   3. Adjust the tire pressure to the specified pressure value.
   4. Maintain no-load in vehicle.
   5. Check if the following conditions are satisfied.
      • Engine: Running
      • Shift position: P Range
      • Steering wheel: Center (within ±15 degrees)
      • ProPILOT Assist: OFF
      • Vehicle speed: 0 km/h
      • ADAS control unit 2 voltage: More than 10.5 V
   6. Release the parking brake.

   Refer to Work Procedure (Steering Torque Calibration).

Work Procedure (Steering Torque Calibration) 

NOTE:

• The steering wheel is operated automatically when "Start" is touched.
• Do not touch the steering wheel.

1. STEERING TORQUE CALIBRATION 

   CONSULT

   NOTE: Operate CONSULT outside the vehicle, and close all the doors.
   1. Select "Work Support", then "Steering Torque Calibration".
   2. Select "START" to begin the Steering Torque Calibration.
      NOTE: Never touch steering wheel or shake the vehicle when the Steering Torque Calibration is conducted.
   3. Confirm the displayed item.
      • "Completed": Select "Completion".
      • "Abnormally completed": Perform the following services.

   Displayed item possible cause service procedure:

   Possible Cause	Action
   Steering wheel torque value is out range.	Check install condition of steering system (from torque sensor to steering wheel). After repairing or replacing error-detected parts, perform calibration again.
   Out of execution condition.	Ensure the following items are within the specified range: ADAS control unit 2 power supply: more than 10.5 V Shift position: P range Steering wheel: Center (within ±15 degrees) Vehicle speed: 0 km/h Touched the steering wheel during calibration: retry without touching the steering wheel. Some parts are not normal: Perform "All DTC Reading" with CONSULT. Touch "Retry" after satisfying the execution conditions.
   Calibration for torque value is abnormally completed.	Touch "Retry".

   Confirm that "Completed" is displayed and then select "End" to close the adjustment procedure.
