This unit is sometimes referred to as the Selective Catalyst Reductant (SCR) module or the Adblue Delivery Module (ADM). Units exposed to hydrocarbons have a particular failure mode, the rubber heater unit is crinkled and in some cases the metal heater protrudes through the rubber membrane. The rubber material used in this unit is designed to withstand Diesel Exhaust Fluid (DEF) only. Exposure to fluids that contain hydrocarbons (i.e. diesel fuel) will damage the unit beyond repair. Units returned that exhibit this failure mode will have warranty claims that are rejected. Units that exhibit this failure mode should be considered customer abuse and should not be covered under warranty. Use the Hydroscopic test paper (P/N 223-44-863) available through MoparEssentialTools.com to confirm exposure.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10226281-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10226281-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10226281","components":[{"id":"engine","name":"Engine","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"RAM","model":"2500","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_ram_2500","2014_ram_2500"]},{"make":"RAM","model":"2500","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_ram_2500"]},{"make":"RAM","model":"3500","year_from":2013,"year_to":2016,"match":"exact","vehicle_ids":["2013_ram_3500","2014_ram_3500","2015_ram_3500","2016_ram_3500"]},{"make":"RAM","model":"4500","year_from":2013,"year_to":2016,"match":"exact","vehicle_ids":["2013_ram_4500","2014_ram_4500","2015_ram_4500","2016_ram_4500"]},{"make":"RAM","model":"5500","year_from":2013,"year_to":2016,"match":"exact","vehicle_ids":["2013_ram_5500","2014_ram_5500","2015_ram_5500","2016_ram_5500"]},{"make":"RAM","model":"PROMASTER 2500","year_from":2015,"year_to":2015,"match":"exact","vehicle_ids":["2015_ram_promaster-2500"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
