Service bulletin SSM 54629

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.

NHTSA's 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.

SSM 552402026-10-13. 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.
TSB 26-23802026-09-29. Service bulletin. This article supersedes TSB 25-2575 to update the Parts list to add the applicable body wiring harnesses and underbody shield bolts. Some vehicles listed in the Model statement above may exhibit a "Sta-bar Disconnect Service Required" message in the instrument panel cluster (IPC) with any of the following diagnostic trouble codes (DTCs) stored in the chassis control module (CHCM): C103A, C1A99, C1B03, C1B07, C1B14 and/or B1A67. This may be due to water intrusion in the stabilizer bar wiring harness connector.

SSM 550732026-08-11. Service bulletin. Some 2021-2026 Bronco vehicles may require the removal and installation of the transfer case for various reasons. Installation requires Loctite® 243 adhesive applied to the mounting bolt threads in the transmission. Make sure that the mating faces are clean and dry. Tightening the mounting bolts also requires an updated two-stage tightening sequence. Workshop Manual (WSM), Sections 307-07C/D and 308-07C/D Installation > Transfer Case have been updated to reflect this change.
