Service bulletin 18M06-S1

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.

SSM 47641	2019-01-07. Service bulletin. Some 2011-2019 F-Super Duty, 2015-2019 Transit, 2016-2019 F-650/F-750 and 2018 F-150 vehicles equipped with a 6.7L, 3.2L or 3.0L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P207F, P20EE, P229F, P2201 and/or P24AE. This may be a result of using aftermarket cleaning liquids or tools for the exhaust gas recirculation (EGR) cooler or intake. Ford does not recommend the cleaning of diesel intakes or EGR coolers using any aftermarket tool that injects a cleaning foam or liquid substance into the EGR cooler or intake. Using these types of fluids can result in sodium poisoning of the NOx and particulate matter (PM) sensors resulting in degraded operation and permanent damage to the aftertreatment system. Use of these cleaning tools may void the emissions warranty of the hot end aftertreatment exhaust system and the attached emissions sensors.
tsb18-2223	2018-09-10. Service bulletin. Some 2015-2018 Transit vehicles equipped with a 3.2L diesel engine may exhibit "Drive To Clean" maintenance messages and/or an illuminated malfunction indicator lamp (MIL) on with DTC P2459, P2463, and/or P246C. Vehicles may also exhibit frequent automatic exhaust regeneration attempts. This may be due to vehicles being used in a stationary or off-highway, low speed applications. If automatic regeneration attempts are unsuccessful, these symptoms may be a result of soot accumulation in the diesel particulate filter (DPF). These vehicles may benefit from operator commanded regeneration (OCR) capability so complete regeneration cycles may be performed in a stationary setting. Information only, follow the Service Procedure steps to correct the condition.

SSM 46085	2017-08-01. Service bulletin. The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
SSM 46122	2017-02-07. Service bulletin. SOME 2015-2017 TRANSIT VEHICLES EQUIPPED WITH A 3.2L PUMA DIESEL ENGINE MAY EXHIBIT AN OVERHEAT CONDITION DUE TO COOLANT LOSS WITHOUT ANY EXTERNAL COOLANT LEAKS. THIS MAY BE DUE TO AN INTERNALLY LEAKING EXHAUST GAS RECIRCULATION (EGR) COOLER. TO CORRECT THIS CONDITION, INSTALL REVISED EGR COOLER CK4Z-9U433-B. REFER TO WORKSHOP MANUAL (WSM), SECTION 303-08. USE CAUSAL PART 9U433 AND APPLICABLE LABOR OPERATIONS FROM SECTION 09 OF THE SERVICE LABOR TIME STANDARDS (SLTS) MANUAL.
