INSPECTION
PROCEDURE
1. INSPECT SPIRAL CABLE SUB-ASSEMBLY
NOTICE:
(a) Visually check the spiral cable sub-assembly for defects.
(1) The defects are as follows:
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.
*a | Component without harness connected (Spiral Cable Sub-assembly) | *b | Color: Light Green |
*c | Color: Black | - | - |
![]() | Interlock | - | - |
NOTICE:
(1) Set the spiral cable sub-assembly to the center position.
