PURPOSE: Initial Release. This bulletin informs dealers that the Anti-lock Braking System / Electro -Hydraulic Control Unit (ABS EHCU) module on some S2 Del Mar and Mulholland vehicles have a software configuration that prevents them from being unlocked. This prevents the ability to perform an ABS service bleed and software updates. It does not affect the operation of Anti-lock Braking System (ABS). The update is applied by Digital Technician II (DT II) and will apply a seed and key to the Electro Hydraulic Control Unit (EHCU), which enables it to be unlocked via DT II or Firmware Over The Air (FOTA) update. The affected vehicles will also require an EHCU reflash following the update.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11029740-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11029740-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11029740","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null},{"id":"speed-control","name":"Throttle and cruise control","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LIVEWIRE","model":"S2 DEL MAR","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_livewire_s2-del-mar"]},{"make":"LIVEWIRE","model":"S2 MULHOLLAND","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
