April 5, 2026: LEMON Manuals is launched! Read the announcement.

Inspection Procedure

  1. CLEAR DTC 
    1. Clear the DTCs (See DTC CHECK / CLEAR ).

    NEXT: Go to next step 

  2. INITIALIZE ROTATION ANGLE SENSOR VALUE AND CALIBRATE TORQUE SENSOR ZERO POINT 
    1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point (See CALIBRATION ).

    NEXT: Go to next step 

  3. RECONFIRM DTC 
    1. Check for DTCs (See DTC CHECK / CLEAR ).

    Condition Proceed To
    DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times. A
    DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration once or twice. B
    Normal system code is output. C

    HINT:

    Replace the power steering ECU assembly if DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.

    B: GO TO step   2 

    C: END 

    A: Go to next step 

  4. REPLACE POWER STEERING ECU ASSEMBLY 
    1. Replace the power steering ECU assembly (See POWER STEERING ECU ).

    NEXT: Go to next step 

  5. CLEAR DTC 
    1. Clear the DTCs (See DTC CHECK / CLEAR ).

    NEXT: Go to next step 

  6. INITIALIZE ROTATION ANGLE SENSOR VALUE AND CALIBRATE TORQUE SENSOR ZERO POINT 
    1. Initialize the rotation angle sensor value and calibrate the torque sensor zero point (See CALIBRATION ).

    NEXT: Go to next step 

  7. RECONFIRM DTC 
    1. Check for DTCs (See DTC CHECK / CLEAR ).

    Result 

    RESULT CHART

    Condition Proceed To
    DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration 3 times. A
    DTCs are still output after performing rotation angle sensor initialization and steering zero point calibration once or twice. B
    Normal system code is output. C

    HINT:

    Replace the power steering link assembly if DTCs are still output after performing rotation angle sensor value initialization and steering zero point calibration 3 times.

    NOTE: If replacing the power steering link assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor value, and calibrate the torque sensor zero point (See CALIBRATION )

    B: GO TO step   6 

    C: END 

    A: REPLACE POWER STEERING LINK ASSEMBLY
