Purpose for Service Bulletin
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.

Program Duration
This program is effective starting on March 25th, 2025. Be
advised that services delivered under this product program
will no longer be rendered at factory expense after March 25,
2027.

Replace TCU module if VIN is the on affected VIN list. See
