SPIRAL CABLE INSPECTION

CAUTION / NOTICE / HINT

Note

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

PROCEDURE


  1. INSPECT SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY (w/o Steering Heater)


    1. Visually check for defects with the spiral cable with sensor sub-assembly removed from the vehicle.


      1. The defects are as follows:


        • Scratches on the spiral cable with sensor sub-assembly

        • Small cracks on the spiral cable with sensor sub-assembly

        • Dents on the spiral cable with sensor sub-assembly

        • Chips on the spiral cable with sensor sub-assembly

        • Cracks or other damage to the connector

          OK
          No defects are found.

        Tech Tips

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

    2. Check the spiral cable with sensor sub-assembly.
