Title: SUPPLEMENTAL RESTRAINT SYSTEMS: SPIRAL CABLE: INSPECTION; 2019 - 2022 MY Avalon Avalon HV [04/2018 -        ]

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.

NOTICE:

  • 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.
