Summary

Some 2017 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 turn outage and outage ABM and change the setting on each parameter from outage to no outage. Changes to lamp outage settings on pickups as a result of upfitter modifications are non-warrantable. Upfitters are responsible for FMVSS 108 compliance.
