Service bulletins for the 2020 Ford Mustang

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 547202026-04-10. Service bulletin. ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. Various 2020-2026 Ford and Lincoln vehicles equipped with blind spot information system (BLIS) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster (IPC). This may also be accompanied by diagnostic trouble codes (DTCs) B118C:11 and/or B118C:15 stored in the driver door module (DDM), and/or B118D:11 and/or B118D:15 stored in the passenger door module (PDM). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z-14A411-B to resolve the concern.

The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad.

SSM 541162025-08-12. Service bulletin. UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Various 2019-2024 Ford and Lincoln vehicles equipped with SYNC 3 may experience a partially or fully black center display screen at start-up using Apple CarPlay or Android Auto. This does not affect rear camera operation. This may be due to interference from the phone being connected into the media hub using a universal serial bus (USB) cable during SYNC system boot up. To correct his condition, advise the customer to disconnect the USB cable from the phone. If the center display screen displays normally, reconnect the phone. If the concern persists, disconnect the phone from the USB cable, cycle the ignition off and open the driver's door so the interior lights come on. Close the door, start the vehicle and wait for the center display screen to boot up past the start-up animation and display the home screen, then reconnect the phone using the USB cable. If the concern persists after this procedure, follow normal Workshop Manual diagnostics for a blank screen concern.
