   HINT: 

   When the spiral cable with sensor sub-assembly is centered, the alignment marks are aligned and the colored roller (yellow) or flat cable shown in the illustration is visible.

2. If the spiral cable with sensor sub-assembly is not centered, center it.

   If the cable cannot be centered, it is possible that the spiral cable with sensor sub-assembly is broken. Replace the spiral cable with sensor sub-assembly with a new one.

   1. While pushing on the interlock indicated in the illustration, rotate the spiral cable sub-assembly counterclockwise slowly by hand until it stops.

      Interlock

      NOTE:

      • When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock indicated in the illustration to release the interlock mechanism.
      • Do not turn the spiral cable with sensor sub-assembly using the airbag wire harness.
   2. Rotate the spiral cable with sensor sub-assembly approximately 2.5 rotations in the clockwise direction from the locked position until the colored roller (yellow) or flat cable can be seen, and then align the alignment marks.

      HINT: 

      The spiral cable with sensor sub-assembly will rotate approximately 2.5 turns to both the left and right from the center.

1. Check that the engine switch is off.
2. Check that the cable is disconnected from the negative (-) battery terminal.
   WARNING:

   • Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
