# Service bulletin TSB 22\-2443

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.

- Type: Service bulletin
- NHTSA id: 10226938
- Published by NHTSA: 2022\-12\-02

## NHTSA's summary

This article supersedes TSB 22\-2313 to update the Parts List, Service Procedure, and vehicle production fix dates. Some 2020\-2022 F\-Super Duty vehicles may exhibit a condition where the engine will not turn off and/or have various electrical symptoms including a dead battery, horn stays on and no crank/no start. The vehicle may also have an illuminated anti\-lock braking system \(ABS\) indicator with diagnostic trouble codes \(DTCs\) C0020 and U3003 in the ABS module. This may be a result of water/moisture intrusion into the battery junction box \(BJB\). The BJB is located under the hood of the vehicle. This water/moisture intrusion may be related to the BJB cover not installed completely or broken cover tabs/locking fingers allowing water/moisture into the BJB. To correct the condition, follow the Service Procedure to inspect for water/moisture intrusion into the BJB and replace the BJB and cover if water/moisture intrusion is found.

## Other bulletins for the same vehicles and component

- [TSB 26\-2375 v2](/bulletins/11038441.md), 2026-10-13, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM; POWER TRAIN. NOTE: This bulletin has been updated, refer to the change log at the bottom for details. Issue: Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: • Poor shift quality • Illuminated powertrain malfunction \(wrench\) indicator with DTCs P2704 and P0771 stored in the PCM / TCM . This may be due to a calibration in the TCM and/or wear between the input shaft and the E clutch hub causing theinput shaft O\-rings to become damaged resulting in an open E clutch circuit. Action: For vehicles that meet all of the criteria in the Issue and Model statements, follow the Service Procedure toreprogram the PCM / TCM and/or replace the E clutch hub and input shaft O\-rings
- [TSB 26\-2375](/bulletins/11036283.md), 2026-08-19, Service bulletin: POWER TRAIN; ENGINE; ELECTRICAL SYSTEM. This article supersedes TSB 26\-2050 to increase the labor operation allowance of labor operations A and B. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Poor shift quality Illuminated powertrain malfunction \(wrench\) indicator with diagnostic trouble codes \(DTC\) P2704 and P0771 stored in the PCM/TCM. This may be due to a calibration in the TCM and/or wear between the input shaft and the E clutch hub causing the input shaft O\-rings to become damaged resulting in an open E clutch circuit. Additional model information: 6.7L Diesel Engine 2022\-2024 F\-550 or F\-600 F\-Super Duty vehicles built on or before 15\-May\-2024 with over 5,000 miles \(8,000km\)
- [SSM 55031](/bulletins/11035269.md), 2026-07-28, Service bulletin: UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM; ELECTRICAL SYSTEM. Some 2021\-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop system not operating as intended with a "Check Charging System" message in the instrument panel cluster \(IPC\) while the charging system is operating properly with no charging related diagnostic trouble codes \(DTC\) stored. This may be due to someone using an aftermarket programmer to change the body control module \(BCM\) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F\-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System \(FDRS\) application titled "BCM\-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request \(TSR\) requesting support to revert the BCM configuration
- [SSM 54720](/bulletins/11031263.md), 2026-04-10, Service bulletin: ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. Various 2020\-2026 Ford and Lincoln vehicles equipped with blind spot information system \(BLIS\) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster \(IPC\). This may also be accompanied by diagnostic trouble codes \(DTCs\) B118C:11 and/or B118C:15 stored in the driver door module \(DDM\), and/or B118D:11 and/or B118D:15 stored in the passenger door module \(PDM\). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z\-14A411\-B to resolve the concern.
- [SSM 54589](/bulletins/11029595.md), 2026-03-04, Other: ELECTRICAL SYSTEM. Some 2019\-2024 Ford and Lincoln vehicles equipped with SYNC3 may experience various connectivity concerns with The Ford App Lincoln App including but not limited to: missing activation prompt pop\-upon the vehicle's center display screen when attempting to activate vehicle through The Ford App Lincoln App, incorrect location global positioning system GPS reported through The Ford App Lincoln App, problems with remote commands being performed through The Ford App Lincoln App and or incorrect data information reported on The Ford App Lincoln App. These symptoms will be accompanied by diagnostic trouble code DTC B156D 89 in the TCU. This may be due to the accessory protocol interface module APIM software. To correct the condition, update the APIM software.
- [SYNC\-25.2.0.16.1 SD](/bulletins/11029356.md), 2026-03-03, Over\-the\-air update: ELECTRICAL SYSTEM; VISIBILITY/WIPER; UNKNOWN OR OTHER. "Quality Improvements Include: \- Bug Fixing and Feature improvements. \- Resolves black screen issue caused when there is no SiriusXM disk space."

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
