SSM 518452023-08-14. Service bulletin. ELECTRICAL SYSTEM; EXTERIOR LIGHTING. Some 2020-2023 Explorer vehicles may exhibit a condition of intermittent headlamp operation while the vehicle is OFF and have diagnostic trouble code (DTC) B1533 stored in the body control module (BCM).

Some 2020-2023 Explorer vehicles may exhibit a condition of intermittent headlamp operation while the vehicle is OFF and have diagnostic trouble code (DTC) B1533 stored in the body control module (BCM). This may be due to the internal logic within the headlamp switch. Switch and/or module replacement will not resolve this condition. Headlamp operation is not affected while the vehicle is ON. A new headlamp switch is currently under development to correct this condition. The customer can continue to drive the vehicle until parts become available.
