Quick answer

SERVICE BULLETIN M1557: TOURING AND TRIKE REAR BRAKE SWITCH. PURPOSE: This bulletin informs dealers that Harley-Davidson has a mid year change in how the Touring and Trike vehicles receive its rear brake signal input. The Touring and Trike vehicles will now receive rear brake input signal from a brake switch and will no longer activate the brake light based on rear brake pressure in the Electro Hydraulic Control Unit (EHCU). 2022 Electrical Diagnostic Manual (EDM) and Service Manual will be updated with this change. See Service Information Portal (SIP) for electronic version of manuals.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
