10. Inspect the adjusters.

If the adjusters are out of phase (one adjuster reaches its maximum horizontal or vertical travel in a given direction before the other adjuster) phase the adjusters as follows:

• Horizontal travel
  • Operate the seat control switch until 1 adjuster reaches a full-forward position.
  • Detach the horizontal drive cable from the adjuster which has reached a full-forward position.
  • Operate the seat forward until the other adjuster reaches its forward position.
  • Connect the horizontal drive cable.
  • Inspect the horizontal travel of the seat.
• Front or rear vertical travel
  • Operate the seat control switch until one adjuster has reached a fully raised position at both the front and the rear vertical travel limits.
  • Disconnect both of the vertical drive cables from the adjuster which has reached the fully raised position.
  • Operate the seat control switch until the other adjuster reaches the fully raised position at both of the front and the rear vertical limits.
  • Connect the previously removed front and rear vertical drive cables.
  • Inspect the vertical travel by operating the adjusters through 1 or 2 complete cycles.

    The above operation may be repeated on a "as required basis," if the adjusters do not appear to be in phase after the test cycle.
