| 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. |

| SSM 54431 | 2025-12-10. 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. Replace the brake fluid reservoir and the brake fluid level sensor electrical connector. Do not disconnect the brake fluid level sensor electrical connector, cut the connector 3-4 inches (75-100 mm) from the connector end and leave the brake fluid level sensor electrical connector attached to brake fluid reservoir. Include these parts in the same package when returning warranty replacement brake fluid reservoirs. The brake fluid reservoir with the electrical connector still connected should be packaged in the original box to protect it during shipping. For claiming, use causal part 2L210 and labor operations 2140A and 2219D45WR. |
