Steering Angle Differs between Left and Right: Procedure

  1. CHECK STEERING WHEEL POSITION 
    1. Turn the steering wheel from lock to lock at a speed of approximately 90°/sec. Check if the steering wheel angles between the left and right.

      OK

      The steering wheel is centered.

      HINT: 

      If turning the steering wheel quickly while driving at low speeds, the steering angle may differ between the left and right, or the steering wheel may become off-center. However, this is not a malfunction.

    OK → VGRS SYSTEM IS NORMAL 

    NG: Go to next step 

  2. CHECK STEERING EFFORT 
    1. Start the engine.
    2. Turn the steering wheel.
    3. Measure the steering effort.

      Standard steering effort

      Below 6.9 N*m (70 kgf*cm, 61 in.*lbf)

      HINT: 

      After completing the inspection or repair, attempt to simulate the problem and then perform "READ VALUE USING TECHSTREAM" above again to reconfirm that the problem does not occur See step  1.

    NG → See step   4 

    OK: Go to next step 

  3. CHECK WHEEL ALIGNMENT 
    1. Check wheel alignment for the front. Refer to ADJUSTMENT [09/2012 - ] for 2WD. Refer to ADJUSTMENT [09/2012 - ] for AWD) and rear. Refer to ADJUSTMENT [09/2012 - ] .
      RESULT

      Result Proceed to
      The wheel alignment is normal A
      The front wheel alignment is not normal (for 2WD) B
      The front wheel alignment is not normal (for AWD) C
      The rear wheel alignment is not normal D

      HINT: 

      Adjust the tie-rod ends within the specified values so that the tire angles are the same between the left and right when the steering wheel is turned from lock to lock.

    B → See step   5 

    C → See step   6 

    D → See step   7 

    A → PERFORM STEERING GEAR NEUTRAL POSITION CALIBRATION AND STEERING COLUMN NEUTRAL POSITION CALIBRATION 

  4. GO TO POWER STEERING SYSTEM. Refer to  PRECAUTION [09/2012 - ] 
  5. PERFORM FRONT WHEEL ALIGNMENT ADJUSTMENT. Refer to  ADJUSTMENT [09/2012 - ] 
  6. PERFORM FRONT WHEEL ALIGNMENT ADJUSTMENT. Refer to  ADJUSTMENT [09/2012 - ] 
  7. PERFORM REAR WHEEL ALIGNMENT. Refer to  ADJUSTMENT [09/2012 - ]
