   *a	Flat Cable

   HINT: 

   When the spiral cable sub-assembly is centered, the part indicated by (A) is positioned at the top and the flat cable shown in the illustration can be seen.

2. If the spiral cable sub-assembly is not centered, center it.
   1. While pushing on the interlock shown in the illustration, rotate the spiral cable sub-assembly counterclockwise slowly by hand until it stops.

      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.
      • Do not turn the spiral cable sub-assembly using the airbag wire harness.
      • If the spiral cable sub-assembly cannot be centered, it is possible that the spiral cable sub-assembly is broken. Replace the spiral cable sub-assembly or spiral cable with sensor sub-assembly with a new one.
   2. While pushing on the interlock shown in the illustration, rotate the spiral cable sub-assembly clockwise approximately 2.5 times to the position where the alignment marks are aligned and the flat cable shown in the illustration can be seen.

   *b	Pin
   *c	Lock Pin

   NOTE:

   • Do not remove the lock pin before the spiral cable sub-assembly is installed to the steering sensor.
   • Do not damage the pins of the spiral cable sub-assembly and guides of the steering sensor.
   • The spiral cable sub-assembly can be rotated up to 30° even when the interlock is engaged. Therefore, make sure that both guides are aligned properly when installing the spiral cable sub-assembly to the steering sensor.
2. Remove the lock pin from the steering sensor.
