This Technical Tip reinforces the ELW power disconnect procedure found in the owner's and service manuals. The power disconnect procedure must be followed whenever removing 12 V power. Disconnecting OBC [307-2] and not waiting 5 minutes after placing the OFF/RUN switch in OFF position can cause electrical issues including, but not limited to: • Diagnostic Trouble Codes (DTCs) generated. • Communication errors between the modules (OBC, Electric Vehicle Power-Train (EVPT), Rechargeable Energy Storage System (RESS)) that may be unrecoverable requiring replacement of the part.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10180724-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10180724-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10180724","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"HARLEY-DAVIDSON/LIVEWIRE","model":"ELW (LIVEWIRE)","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
