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.
noteFollow the M.U.T.-III SE when performing Steering Torque Calibration. (Steering Torque Calibration cannot be performed without M.U.T.-III SE).
 
 
Work Procedure (Preparation)
1.PERFORM SELF-DIAGNOSIS
  1. Turn ignition switch ON.
  2. Perform self-diagnosis of "ACC/ADAS 2".
  3. Check if any DTC is detected.
Is any DTC detected?
Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to DTC IndexDTC Index .
.
 
2.PREPARATION BEFORE STEERING TORQUE CALIBRATION
  1. Perform pre-inspection for diagnosis. Refer to Work ProcedureInspection 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)
    • MI-PILOT Assist: OFF
    • Vehicle speed: 0 km/h
    • ADAS control unit 2 voltage: More than 10.5 V
  6. Release the parking brake.

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
M.U.T.-III SE
noteOperate M.U.T.-III SE outside the vehicle, and close all the doors.
  1. Select "Special Function", then "Steering Torque Calibration".
  2. Select "OK" to begin the Steering Torque Calibration.
    noteNever touch steering wheel or shake the vehicle when the Steering Torque Calibration is conducted.
  3. Confirm the displayed item.
    • "Completed"： Select "Home"/"Return one level".
    • “Abnormally completed”: Perform the following services.
Displayed item possible cause service procedure:
Possible CauseAction
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 “Read All DTCs” with M.U.T.-III SE.
  • Touch "Retry" after satisfying the execution conditions.
Calibration for torque value is abnormally completed.Touch "OK" (Retry).
Confirm that "Completed" is displayed and then select "Home"/"Return one level" to close the adjustment procedure.
