| SSM 51645 | 2023-05-23. Service bulletin. Some 2021-2022 Bronco Sport vehicles may exhibit a condition where the low beams turn on by themselves while the vehicle is OFF for 10 or more minutes with diagnostic trouble code (DTC) B1533 stored in the body control module (BCM). This may be due to the internal logic within the headlamp switch. To correct this condition, replace the headlamp switch (service base PN: 11654). Refer Workshop Manual, Section 417-01. |
