Summary
Some 2021-2022 Bronco 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. Let the customer know they can continue to drive the vehicle and schedule a follow-up appointment in October 2022, when parts are expected to become available. Follow up with the customer to confirm the appointment once OASIS is updated with the repair information.
