INSPECTION

PROCEDURE

1. INSPECT SPIRAL CABLE SUB-ASSEMBLY

NOTICE:

  • 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.

(a) Visually check the spiral cable sub-assembly for defects.

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

(b) Check the spiral cable sub-assembly.
