Service bulletin TSB 19-2201

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 2018-2019 Mustang vehicles equipped with a 5.0L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 and/or P0430. This may be due to the operation of the PCM. To correct the condition, follow the Service Procedure steps to replace the affected catalytic converter and reprogram the powertrain control module (PCM).

Other bulletins for the same vehicles and component
TSB 23-2350	2023-11-22. Service bulletin. Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift, an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes This may be due to the software in the powertrain control module (PCM) or transmission control module (TCM), the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve. To correct the condition, follow the Service Procedure to identify and correct the condition.
SSM 51232	2023-01-05. Service bulletin. Some 2018-2022 Mustang vehicles equipped with a 5.0L engine and a 10R80 transmission may exhibit a buck/jerk sensation that may be perceived as an engine misfire during throttle tip-in between 35-45 MPH (56-72 KPH) and with the transmission in 8th, 9th, or 10th gear. This buck/jerk sensation can be compared to a like vehicle that is equipped with a similar powertrain (engine, transmission, and rear end gear ratio) and driven in the same manner. A diagnostic trouble code (DTC) will not set because of this condition. If a misfire DTC is present, the DTC should be diagnosed first following the correct diagnostic procedure outlined in the Workshop Manual, Section 303-07B.
TSB 22-2302	2022-07-28. Service bulletin. Some 2018-2020 Mustang vehicles equipped with a 5.0L engine and an MT-82 manual transmission may experience a loss of movement and/or difficulty shifting. This may be due to excessive wheel hop which is caused by aggressive acceleration at low speeds while using launch control. To correct the condition, follow the Service Procedure to replace the failed components and replace the peak torque limiter.
TSB 21-2315	2021-10-05. Service bulletin. Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang and 2019-2021 Ranger vehicles equipped with a 10R80 automatic transmission may exhibit a harsh engagement/harsh shift/delayed shift. It is possible the vehicle may also have an illuminated malfunction indicator lamp (MIL) or diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to incompatibility of the adaptive calibration to adapt to hardware wear-in over time. To correct the condition, follow the Service Procedure steps to overhaul the main control valve body and/or perform an adaptive learning drive cycle.
SSM 49821	2021-06-01. Service bulletin. Some 2015-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test HK11 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 49292	2020-11-04. Service bulletin. Some 2018-2020 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number (ESN) displayed or DTCs U2100 and/or B156D in the telematics control unit (TCU). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version (if applicable) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14H092 and applicable labor times in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 47750	2019-03-04. Service bulletin. Some 2018-2019 Ford and Lincoln vehicles equipped with a TCU may exhibit inoperative remote features via Ford Pass/Lincoln Way mobile app, incomplete user authorization and/or accessory protocol interface module (APIM) DTC U0198 or no modem electronic serial number (ESN) displayed. To correct this condition prior to programing remove the TCU fuse for 5 minutes then reinstall. Delete all previous session files for the vehicle. Verify that the electronic serial number (ESN) is now displayed. Start a new IDS/FDRS session. Program the TCU to the latest IDS/FDRS version level. Make sure you are connected to the internet before retesting. If the concern is still present, follow normal diagnostics in Workshop Manual(WSM), Section 415-00. Refer to PTS OASIS home page for TCU version identification. For claiming, use causal part 14G229.
TSB 18-2370	2019-03-04. Service bulletin. Some 2018-2019 Mustang vehicles built on or before 17-Oct-2018 equipped with a 2.3L EcoBoost engine and operating in altitudes of 1067 meters (3500 feet) above sea level and higher may exhibit an illuminated MIL with only DTC P0068 stored in the powertrain control module (PCM). Follow the Service Procedure steps to correct the condition.
TSB 18-2360	2019-03-04. Service bulletin. Some 2018 F-150 and 2018-2019 Mustang vehicles equipped with a 5.0L engine may exhibit an illuminated MIL with DTCs P0390 and/or P0394 stored in the powertrain control module (PCM). Follow the Service Procedure steps to correct the condition.
TSB18-2160	2018-07-23. Service bulletin. Some 2017-2018 F-150/Raptor, 2018 Expedition/Mustang/Navigator vehicles equipped with a 10R80 automatic transmission and built on or before 20-Nov-2017 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0741 and P1744 in the powertrain control module (PCM) or transmission control module (TCM). This may be due to a sticking torque converter clutch (TCC) valve in the main control valve body assembly. Follow the Service Procedure steps to correct the condition.
