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. Click here
 (2) Measure the resistance between each terminal of the spiral cable sub-assembly according to the value(s) in the table below.

After setting the spiral cable sub-assembly to the center position,
rotate the spiral cable sub-assembly 2.5 times clockwise, and measure
the resistance according to the value(s) in the table below. Then rotate
the spiral cable sub-assembly 5 times counterclockwise, and measure the
resistance according to the value(s) in the table below. Standard Resistance: |
