SPIRAL CABLE INSPECTION

CAUTION / NOTICE / HINT

Note


  • Do not remove the steering sensor from the spiral cable sub-assembly when inspecting the spiral cable sub-assembly.

  • Remove the steering sensor from the spiral cable sub-assembly only when replacing the spiral cable sub-assembly.

PROCEDURE


  1. INSPECT SPIRAL CABLE SUB-ASSEMBLY


    1. Visually check for defects with the spiral cable sub-assembly.


      1. The defects are as follows:


        • Scratches

        • Small cracks

        • Dents

        • Chips

        • Cracks or other damage to the connector

          OK
          No defects are found.

        If any defects are found, replace the spiral cable sub-assembly with a new one.

    2. Check the spiral cable sub-assembly.

      Note


      • When rotating the spiral cable sub-assembly, make sure to push on the interlock shown in the illustration to release the interlock mechanism.

      • As the spiral cable sub-assembly may break, do not rotate the spiral cable sub-assembly more than the specified amount.


      1. Set the spiral cable sub-assembly to the center position.
