Reason for update: to update the Service Procedure to remove the fuel tank isolation valve replacement and include fuel vapor vent valve replacement and update the causal part number. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to the software in the PCM and/or the fuel vapor vent valve.

> Front Seats > Diagnosis and Testing lead to the replacement of the front seat cushion extension adjuster, a lower-level part is now available (14C720). It is not necessary to replace the front seat cushion extension adjuster if only the front seat cushion extension motor assembly is damaged. For Corsair, use service part LJ7Z-14C720-A. For Aviator, use service part R2TZ-14C720-A. For 2025-2026 Navigator (both sides) and 2018-2024 Navigator driver side, use service part NL7Z-14C720-A. For 2018-2024 Navigator passenger side, use service part NL7Z-14C720-B.

in the WSM, Section 307-01 > Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements (N>R, N>D, R>D, and/or D>R) should be noted in the warranty claim. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.

Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to the software in the PCM and/or the fuel tank isolation valve.

with diagnostic trouble code (DTC) P04CA stored in the powertrain control module (PCM). This may be due to an open circuit on circuit SBB05 and/or a damaged splice S133. Before performing the pinpoint test for P04CA in Workshop Manual (WSM), Section 310-00, inspect circuit SBB05 and splice S133 for damage such as an open circuit. Repair as necessary. Refer to Wiring Diagram, Cell 005. If no damage is found, refer to WSM, Section 310-00 for normal diagnostics. For claiming use causal 14290 and labor operations 12650D, 12650D45, and 12650D45WR.

1.5/2.0/2.3/3.5L EcoBoost engine and built on 01-Oct-2024 and through 31-May-2025 may exhibit an extended crank condition, strong fuel smell in the engine oil, high engine oil level and/or may have various drivability diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) with an illuminated malfunction indicator lamp (MIL). This may be due to an internal fuel leak of the high-pressure fuel pump causing fuel to enter the crankcase and reduce fuel pressure in the direct injection fuel rail. Diagnose this condition using Pinpoint Test HP located in Workshop Manual (WSM), Section 303-04. If no DTCs are stored in the PCM, proceed from Step HP1 to Step HP5 and continue testing. Repair as necessary outside of this article. For claiming, if high-pressure fuel pump replacement is required, use causal part number 9D376 and labor operation code 9543A. If the root cause is identified as anything other than the fuel injection pump, claim the repair outside of this article.

This may be due to a concern with the front courtesy lamp light module.

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

Maverick/Bronco Sport vehicles built on or before 20-Jan-2026 2024-2026 Nautilus vehicles built on or before 02-Dec-2025 2023-2026 Escape/Corsair may exhibit reduced steering assist and a "Power Steering Assist Fault" message displayed in the instrument panel cluster (IPC) with the diagnostic trouble code (DTC) U2016:47 only, and no other steering DTCs stored in the power steering control module (PSCM). To correct this condition, reprogram the PSCM using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 3C529 and labor operations 3504E and PSCM. If a software update is not available for the PSCM, the PSCM is already at the latest software level. Refer to Workshop Manual (WSM), Section 211-02 for normal diagnostics. If the vehicle does not exhibit any observable symptoms described above and the DTC is only present in continuous memory, this DTC should be ignored. No further service action

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.
