Service bulletin SSM 47712

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2017-2019 F-Super Duty and 2016-2019 F650-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2019 F-150 with 3.0L diesel engines may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P206C in the powertrain control module (PCM). Review of repair data supports that P206C is often the result of incorrect diesel exhaust fluid (DEF) concentration. Per Powertrain Control/Emissions Diagnosis (PC/ED) Pinpoint Test (PPT) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.

SSM 550982026-08-25. Service bulletin. Some 2013-2016 Super Duty vehicles equipped with a 6.7L diesel engine and 2015-2019 Transit vehicles equipped with a 3.2L diesel engine may not pass a state smog test due to the exhaust gas system (EGS) monitor that will not run after completing the exhaust gas sensor drive cycle located within Section 2 of the Powertrain Control/Emissions Diagnostics (PC/ED) Manual > Drive Cycles. This may be due to the vehicles diesel oxidation catalyst (DOC) age counter being under the 120-minute age requirement. There is an all-new "PCM Catalytic Converter Age Evaluation" application within the latest version of the Ford Diagnosis and Repair System (FDRS). Use this new FDRS application to determine the age (in minutes) of the DOC. If the age is less than 120 minutes, perform manual regenerations to increase the catalyst age counter to satisfy the monitor age requirement. If further assistance is needed, contact the technical assistance center (TAC). Note: this article only applies to the EGS monitor. Problems with other vehicle monitors not running successfully must be addressed using normal diagnostics located i

This may be due to calibration and controls sensitivity.
