STEERING COLUMN ASSEMBLY(for Power Tilt and Power Telescopic Steering Column) INSPECTION

CAUTION / NOTICE / HINT

Note


  • When using a vise, place aluminum plates between the part and vise.

  • When using a vise, do not overtighten it.

PROCEDURE


  1. INSPECT ELECTRIC POWER STEERING COLUMN SUB-ASSEMBLY


    1. Inspect the preload.


      1. A01H5XVC01
        *a Cloth
        *b Steering Wheel Set Nut or equivalent

        Secure the electric power steering column sub-assembly in a vise between aluminum plates or pieces of cloth as shown in the illustration.

        Note


        • Do not overtighten the vise as the electric power steering column sub-assembly may become deformed.

        • Secure the power steering ECU assembly so that it faces straight up.

      2. Install the 2 nuts to the electric power steering column sub-assembly.

        Tech Tips

        The nuts to use are the steering wheel set nut or equivalents.

        Steering wheel set nut part No. Thread diameter Thread pitch
        90179-12071 12 mm (0.4724 in.) 1.25 mm (0.0492 in.)
      3. A01H6BI

        Turn the steering main shaft by 180° to the left and right at a speed of 1 turn per second. Repeat these movements 2 to 3 times to center the power steering ECU assembly.

      4. A01H6LX

        Check the turning torque of the steering main shaft.

        Standard preload
        0.9 to 1.5 N*m (10 to 15 kgf*cm, 8 to 13 in.*lbf)

        Note

        Make sure that the shaft turns smoothly.

        Tech Tips

        If the result is not as specified, center the power steering ECU assembly again.

    2. Inspect the bushings.


      1. A01H5T7C01
        *a Bushing

        Check that the 2 bushings are securely installed to the electric power steering column sub-assembly.

        Tech Tips

        If the bushings are missing or damaged, replace the electric power steering column sub-assembly with a new one.
