    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".
