Official summary
Some 2017-2018 F-Super Duty pickups may exhibit an instrument panel cluster (IPC) turn signal indicator that flashes fast with no inoperative turn signal lamps after the pickup box has been removed by the upfitter. This may be due to the body control module (BCM) not recognizing the modified lower current turn signal lighting that was installed. To correct this concern, use Integrated Diagnostic System (IDS) service tool version 104.04 or later to configure turn lamp outage settings as required. Under toolbox > module programming > programmable parameters > exterior lighting, select rear bulb

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
