Official summary
Some 2016 F-Super Duty vehicles equipped with a 6.7L and dual generators built on 26-Oct-2015 and through 9-Dec-2015 may exhibit an illuminated malfunction indicator lamp (MIL) with no drivability symptoms and diagnostic trouble codes (DTCs) P02CC, P02CE, P02D0, P02D2, P02D4, P02D6, P02D8 and/or P02DA. This may be caused by a thickness variation in the accessory drive belt due to a cord shift during manufacturing that resulted in excessive tensioner movement at hot idle with no accessory drive belt loads present. To repair, replace the accessory drive belt per workshop manual (WSM) section 303
Vehicles covered
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.
