L10192025-09-09. Service bulletin. ENGINE; EXTERIOR LIGHTING; UNKNOWN OR OTHER. SERVICE BULLETIN L1019: PRODUCT PROGRAM 1901 S2 TCU REPLACEMENT. PURPOSE: LiveWire EV, LLC has identified that certain S2 motorcycles do not recognize the full connectivity benefit due to the lack of completion of regularly scheduled Firmware Over The Air (FOTA) updates. Certain S2 motorcycle’s Telematic Control Unit (TCU) that have not been updated to the latest software version which prevents full operation of the TCU and the motorcycle’s ability to receive FOTA updates will need to be inspected and the TCU replaced. Vehicle performance and safety are not affected. Additionally, there is an upcoming cloud update scheduled for August 31st, 2025, which will prevent motorcycles with these early TCU software versions from connecting to cloud services. If the affected vehicle's TCU is not updated by this time, connected service within the LiveWire S2 mobile app will cease to function.

L10162025-09-09. Service bulletin. EXTERIOR LIGHTING; ELECTRICAL SYSTEM; UNKNOWN OR OTHER. SERVICE BULLETIN L1016: S2 TCU UPDATE PROCEDURE FOR V4.0.6 AND EARLIER.

L10132025-09-09. Service bulletin. UNKNOWN OR OTHER; EXTERIOR LIGHTING; ELECTRICAL SYSTEM. SERVICE BULLETIN L1013: S2 DEL MAR TCU CELLULAR CONNECTIVITY. PURPOSE: This bulletin informs that there is a population of S2 Del Mar motorcycles where the Telematic Control Unit (TCU) is not communicating on the cellular network. A TCU that is not communicating will prevent the LiveWire S2 mobile app from pairing with the motorcycle. That will prevent the app from displaying information such as Charge Level, Available Range, or charging progress. It will not allow the navigation feature to function on the instrument module. Firmware Over the Air (FOTA) updates are also not available without a cellular signal. The symptoms are: the customer cannot pair the motorcycle to the mobile app after repeated attempts, or the TCU signal strength display in the Bike Status screen always shows no signal. The cause for this issue is TCU software based and will be addressed in a future update. Current estimate time for a Digital Technician II (DT II) field release is June 2024.
