      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 or 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.
  2. INSPECT SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY 
    1. Check that the spiral cable with sensor sub-assembly is center position.

      OK

      The connector is at the top.

      The matchmarks are aligned.

      The colored roller or the top of the flat cable U-turn can be checked from the check window.
