SummaryFor 20202026 vehicles equipped with the 10R140 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.

SummaryVarious 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.

SummaryFord 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.

SummaryFor 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.
