SSM 55098	2026-08-25. 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

SSM 54601	2026-02-27. Service bulletin. Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k
TSB 25-2570	2025-12-01. Service bulletin. This article supersedes TSB 24-2165 to update the TSB Service Procedure. Some vehicles listed in the Model statement above may exhibit various SYNC performance related concerns including but not limited to: Display operation concerns Navigation inoperative Voice recognition concerns Phone connection issues Dropped phone connections Applink related performance Travel Link not present or showing incorrect traffic Slow system response NOTE: Ford has found some of the APIMs replaced and returned for inspection contained an outdated software level and the APIM did not require replacement. The customer concern may have been resolved by updating the APIM with latest level of software. The SYNC 3 universal thumb drive will be able to update the APIM software without the use of a scan tool and does not require the process to be monitored. Ford will be monitoring APIM replacements to confirm TSB directed software updates have been performed.

TSB 24-2099	2024-05-02. Service bulletin. This article supersedes TSB 22-2444 to add 2024 model year vehicles. Some 2015-2024 Transit vehicles equipped with rear wheel drive (RWD), single rear wheel (only), and U-joints at the transmission flange and rear driveshaft may experience a boom/hum/moan noise from the rear while driving. This noise is most noticeable at highway speeds: 112-121 km/h (70-75 mph) for 4.10 axle ratio 121-128 km/h (75-80 mph) for 3.73 axle ratio 136-145 km/h (85-90 mph) for 3.31 axle ratio The noise may also be present to a lesser degree at roughly half of the noted speeds. This may be due to a 2nd order driveline frequency transmitted through the rear driveshaft, rear axle and into the body through the leaf springs.
SSM 52314	2024-03-20. Service bulletin. During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical.

Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual (WSM) Section, 303-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
