When using the FordPass/Lincoln Way application, the customer may receive a message saying Wi-Fi has been disabled from this vehicle. Check the vehicle specifications or vehicle build information for the mfal code on the PTS website (Detailed Vehicle Specifications). If mfal = WAFAC or WAFAB do not replace the TCU, engineering is currently investigating this condition. Inform customers Ford is developing a software fix that is expected in early March. In the interim, let the customer know they can continue to drive the vehicle and schedule a follow-up appointment with the customer for early March. Monitor OASIS for updates.
SSM 494832021-02-04. Service bulletin. POWER TRAIN. Some 2017-2021 F-Super Duty and 2016-2021 F650-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2021 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.
