The BTO system will temporarily close the throttle plate and, in some cases, illuminate the Malfunction Indicator Lamp (MIL) if the brakes and throttle are applied at the same time while the vehicle is in motion. While this operation is normal, it is not always compatible with each individual riding style.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10178839-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10178839-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10178839","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"INDIAN","model":"CHIEF","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF CLASSIC","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF DARK HORSE","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF VINTAGE","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEFTAIN","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEFTAN","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEFTAN DARK HORSE","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"DARK HORSE","year_from":2015,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"VINTAGE","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.
