STEERING SYSTEM ADJUSTMENT

CAUTION / NOTICE / HINT

Tech Tips


  • Use the same procedure for RHD and LHD vehicles.

  • The procedure listed below is for LHD vehicles.

PROCEDURE


  1. STEERING OFF CENTER ADJUSTMENT

    Tech Tips

    This is the adjustment procedure for when the steering is off-center.


    1. Check if the steering wheel is off-center.


      1. A01HGHEC01
        *1 Steering Wheel
        *2 Upper Steering Column Cover
        *a Masking Tape

        Apply masking tape to the top center of the steering wheel and upper steering column cover.

      2. Drive the vehicle in a straight line for 100 m (328 ft.) at a constant speed of 56 km/h (35 mph) and hold the steering wheel assembly to maintain the course.

      3. A01HGGBC01
        *1 Steering Wheel
        *2 Upper Steering Column Cover
        *a Marked Line

        Draw a line on the masking tape as shown in the illustration.

      4. Turn the steering wheel assembly to the center position.

        Tech Tips

        Look at the upper surface of the steering wheel assembly, steering spoke and SRS airbag line to find the center position.

      5. A01HGZ3C01
        *1 Steering Wheel
        *2 Upper Steering Column Cover
        *a Marked Line

        Draw a new line on the masking tape on the steering wheel assembly as shown in the illustration.

      6. Measure the distance between the 2 lines on the masking tape on the steering wheel assembly.

      7. Convert the measured distance to a steering angle value.

        Tech Tips


        • Measured distance 1 mm (0.0394 in.) = Steering angle of approximately 1°.


        • Make a note of the steering angle.

    2. Adjust the steering angle.


      1. A01HEWSC04
        *a Matchmark

        Place matchmarks on the RH and LH tie rod ends and rack ends respectively where they can be easily seen.

      2. Using a paper gauge, measure the distance from the RH and LH tie rod ends to the rack end screws.

        Tech Tips


        • Measure both the RH and LH sides.

        • Make a note of the measured values.

      3. A01HDZU

        Remove the RH and LH boot clips from the rack boots.

      4. Loosen the RH and LH lock nuts.

      5. Turn the RH and LH rack ends by the same amount (but in different directions) according to the steering angle value.

        Tech Tips

        One 360° turn of a rack end (1.5 mm (0.0591 in.) horizontal movement) is equal to a 12° change in steering angle.

      6. Tighten the RH and LH lock nuts to the specified torque.

        Torque:
        88 N*m  { 897 kgf*cm, 65 ft.*lbf }

        Note

        Make sure that the difference in length between the RH and LH tie rod ends and rack end screws is within 1.5 mm (0.0591 in.).

      7. Install the RH and LH boot clips.

      8. Perform rotation angle sensor output calibration.
