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.
