SPIRAL CABLE INSPECTION
PROCEDURE
-
INSPECT SPIRAL CABLE SUB-ASSEMBLY
Note
-
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.
-
Visually check the spiral cable sub-assembly for defects.
-
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.
-
-
-
Check the spiral cable sub-assembly.

Interlock - - Note
-
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.
-
Set the spiral cable sub-assembly to the center position.
-
Measure the resistance between each terminal of the spiral cable sub-assembly according to the value(s) in the table below.
