VARIABLE GEAR RATIO STEERING SYSTEM Steering Angle Differs between Left and Right

INSPECTION PROCEDURE

Tech Tips


  • Check that the steering wheel is centered.

  • After checking that no DTC is output for the VGRS system, perform the following procedure.

PROCEDURE


  1. CHECK STEERING WHEEL POSITION


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

      The steering wheel is off-center A
      The steering wheel is centered B

      Tech Tips

      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.

  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)

      Tech Tips

      After completing the inspection or repair, attempt to simulate the problem and then read the Data List again to confirm that the problem does not occur.

      OK
      The wheel alignment is normal.

      Tech Tips
