Service bulletins for the 2021 Ford Explorer

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.

SSM 529412024-10-01. Service bulletin. EXTERIOR LIGHTING. Some 2020-2025 Police Interceptor Utility hybrid vehicles may exhibit multiple warning messages, various driveability concerns and/or an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P061B stored in the powertrain control module (PCM).
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). 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.
SSM 516282023-05-16. Service bulletin. EQUIPMENT:ELECTRICAL; 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). 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. Monitor OASIS for updated repair information.
SSM 507052022-04-20. Service bulletin. STRUCTURE:BODY:DOOR; ELECTRICAL SYSTEM; EXTERIOR LIGHTING:TURN SIGNAL. Some 2021 Explorer vehicles may exhibit inoperative side marker turn signals. This may be due to incorrect data in the driver door module (DDM). To correct the condition, run the DDM and passenger door module (PDM) Configuration Application using the latest level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14B291 and applicable labor times found in Section 10 of the Service Labor Time Standards (SLTS) Manual.
TSB 21-21952021-07-01. Service bulletin. EXTERIOR LIGHTING. Some 2020-2021 Police Interceptor Utility vehicles may exhibit inoperative turn signal lamps after replacement of the light emitting diode (LED) control module. This may be due to a lack of initialization caused by incomplete wiring circuits. To correct the condition, follow the Service Procedure to splice the needed circuits into the wiring harness of the affected side of the vehicle.
