Issue 1: Program incompatibility causes throttle response to drop to zero when an attempt is made to operate in economy (Eco) mode. Issue 2: ?Liters to Empty? Smart Gauge function is not programmed; at fuel levels less than 5-10%, zero throttle response results. Agility® is coding a new ECU calibration to remedy these conditions which will be distributed through the Cummins INSITE customer online portal.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10174934-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10174934-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10174934","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"AGILITY FUEL SYSTEMS","model":"CNG FUEL SYSTEM","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"AGILITY FUEL SYSTEMS","model":"CNG FUEL TANK","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"AGILITY FUEL SYSTEMS","model":"CNG PRESSURE RELIEF DEVIC","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
