| SSM 55240 | 2026-10-13. Service bulletin. Some 2021-2024 Bronco vehicles may exhibit an illuminated red brake warning indicator with diagnostic trouble code (DTC) C0049:01 stored in the anti-lock brake system (ABS) module. This may be due to pin fitment at the brake fluid level sensor connector. To resolve this concern, replace the brake fluid reservoir and replace the brake fluid level sensor electrical connector C1052 with service pigtail wiring kit 3U2Z-14S411-BXAB. For claiming, use causal part 2L210 and labor operations 2140A and 2219D45WR. |

Some 2023-2026 F-Super Duty vehicles equipped with a trailer brake control module and built on or before 08-May-2026 may exhibit a "Trailer Disconnected" message after cycling the ignition off and back on with a trailer connected. This may be due to the presence of an integrated battery charger on a trailer equipped with electric over hydraulic brakes. If trailer functionality is restored after unplugging and plugging the trailer connector back in while the ignition is on, this condition can be corrected by downloading and performing the "Trailer Brake Configuration" application using the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 19H332 and labor operations 12651D and 12651D4.

| SSM 55221 | 2026-10-12. Service bulletin. For 20222026 vehicles equipped with a 8F35 transmission, a revision to the Road Testing Vehicle procedure has been made 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. |
