During the affected model years some Oliver models relied upon providing a ground to the electric braking system through the connection between the tow vehicle hitch and trailer frame. This usually provides sufficient grounding capacity for the brakes to operate normally, however, a better method of grounding the trailer would be to provide a grounding bond through the 7-pin ground wire to the trailer frame.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10164356-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10164356-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10164356","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"trailer-hitch","name":"Trailer hitch","parent":null},{"id":"wiring","name":"Wiring and fuses","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"OLIVER TRAVEL TRAILERS","model":"LEGACY ELITE","year_from":2015,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"OLIVER TRAVEL TRAILERS","model":"LEGACY ELITE II","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
