    Note
    Perform a push-pull-push test at each end of air line to ensure proper seating in voss fitting. If line dislodges at either end, discontinue procedure then add relevant correction code for repair.
  18. Secure the air suspension fill tube.
  19. Position the RH rear wheel liner to the fender carrier, and then install the clips (x2) that attach the liner to the carrier.
  20. Install the RH rear fender flare. See Front and Rear Garnish - Rear Fender Flare - RH (Remove and Install).
  21. Install the bed floor assembly. See Truck Bed - Bed Floor Assembly (Remove and Install).
  22. Close the tonneau cover.
  23. Close the tailgate.
  24. Park the vehicle where it can remain for 12 or more hours.
    Informational PurposesAn informational icon, calling your attention
    Note
    If possible, leave the vehicle parked in a climate controlled area to avoid pressure variation due to temperature change.
  25. On the vehicle touchcreen, navigate to UI > Service Mode > Chassis > Suspension, and then record the air suspension height sensor values (in millimeters) from each corner.
  26. Leave the the vehicle in position for 12 or more hours.
  27. Record and compare the air suspension height sensor values with those recorded prior to test.
    Informational PurposesAn informational icon, calling your attention
    Note
    Investigate further if ride height has dropped in excess of ~5mm at any corner. If a single corner shows evidence of droop, there is likely an internal air spring module leak that requires the air spring to be replaced. If multiple or all corners have dropped further, diagnostic steps are required. Discontinue the procedure then add relevant correction code as required.
  28. Remove the air suspension from "Jack Mode" and set the ride height to "Medium".

    Note
    For "Jack Mode": UI > Controls > Service > Jack Mode. To set the ride height to "Medium": UI > Controls > Ride Height > Medium
  29. Raise the LH front window and close the LH front door.
