Lexus NX: Inspection
INSPECTION
PROCEDURE
1. INSPECT SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY
NOTICE:
- Do not remove the steering sensor from the spiral with sensor cable sub-assembly.
- As the spiral with sensor cable sub-assembly may break, do not rotate the spiral with sensor cable sub-assembly more than the specified amount.
(a) Visually check for defects with the spiral with sensor cable sub-assembly.
(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 with sensor cable sub-assembly with a new one.
(b) Check the spiral with sensor cable sub-assembly.

NOTICE:
When rotating the spiral with sensor cable sub-assembly, make sure to push on the interlock indicated in the illustration to release the interlock mechanism.
(1) Set the spiral with sensor cable sub-assembly to the center position.
