  Summary

  For 20202026 vehicles equipped with the 10R60 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System (FDRS). This test utilizes the pressure and vacuum transducer (PVT) when available. Workshop Manual (WSM) updates related to this diagnostic procedure are planned for release in Q4 2026. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification for transmission replacement.

  Summary

  Some 2021-2024 Bronco vehicles equipped with a manual transmission may experience a rotational scraping noise while the transmission is in neutral, 1st and/or 2nd gear with the clutch pedal released. The noise may be more noticeable in ambient temps below 10°C (50°F) and after a cold soak. This noise may also diminish as the transmission warms up. This may be due to the 5th and 6th gear synchronizer rings. The 5th and 6th gear synchronizer rings are now only available in the 6th/5th gear synchronizer assembly (service part number MU7Z-7124-Q). To correct the condition, replace the 6th/5th gear synchronizer. Remove the transmission from the vehicle. Refer to Workshop Manual (WSM), Section 308-03 > Removal. Disassemble the transmission. Refer to WSM, Section 308-03 > Disassembly. Disassemble the input shaft to gain access to the 6th/5th gear synchronizer. Refer to WSM, Section 308-03 > Disassembly and Assembly of Subassemblies > Input Shaft. Replace the 6th/5th gear synchronizer and assemble the input shaft. Assemble the transmission. Refer to WSM, Section 308-03 > Assembly. Install the transmission.

  Summary

  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.

  Summary

  Some 2021-2023 Bronco vehicles may exhibit a charging system lamp that illuminates intermittently, and/or diagnostic trouble code (DTC) B11DB:08 in the body control module (BCM). This may be due to a loose fuse terminal for the low voltage high current fuse (3A). If this condition is present, compare fuse removal effort between the low voltage high current fuse and like fuses in the battery junction box (BCMC). If removal effort for the fuse is low, replace the low voltage high current fuse panel assembly to correct this condition. Refer to Workshop Manual (WSM) Section 414-01 > Removal and Installation > Low Voltage High Current Fuse. For claiming, use causal part 14526 and labor time MT14526SSM with a limit of 0.5 hours.

  Summary

  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

  Summary

  For 20172026 vehicles equipped with a 10R transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, located in 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, or D>R) should be noted. 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.
