Service bulletins for the 2016 Ram 4500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

T132018-06-11. Service bulletin. POWER TRAIN. Customer Satisfaction Notification T13 Manual Transmission Shift Lever The manual transmission shift lever rubber insert on about 4,300 vehicles may not have properly adhered to the metal shifter housing during the shifter manufacturing process. This condition could cause looseness in the gear shift lever, noise, and additional effort to move the shifter into the selected gear. The manual transmission shift lever must be replaced on all involved vehicles.
90030592018-06-11. Service bulletin. EQUIPMENT:ELECTRICAL. Park Assist Sensor 1) Active or Stored DTC of Signal Shape / Waveform Failure fault: B128E-25, B128F-25, B1290-25, B1291-25, B1292-25, B1293-25, B1295-25, B1296-25, B1297-25, and/or B1298-25, check for snow/mud/ice/obstruction and clean the Sensors, both front and back (behind bumper) of sensor. The snow/mud/ice can be behind the bumper, sensor retainer and/or the sensor which may cause customers to think they have an issue since they cleaned the front of the sensor/bumper, but not behind where dirt/mud/ice snow can accumulate. Once the Bumper and Sensors are completely cleaned and clear of snow, mud, ice, and/or obstruction, the sensors must activate in order for the faults to go STORED. After cleaning the Bumper and Sensors, turn off the engine, wait 10 seconds, turn on the engine and then place the vehicle in REVERSE so that the sensors activate. The faults will go STORED. 2) Active or Stored DTC code of Short to Ground fault: B128E-11, B128F-11, B1290-11, B1291-11, B1292-11, B1293-11, B1294-11, B1295-11, B1296-11, and/or B1298-11, or if you have an active or stored DTC code of Performance or Incorrect Operation fault: B128E-92, B128F-92, B1290-92, B1291-92, B1293-92, B1294-92, B1295-92, B1296-92, B1297-92, and/or B1298-92, then check the wiring behind the sensor. Specifically, ensure that the connector behind the park assist sensor is fully mounted. Ensure also, there is no dirt, corrosion, or damage in this connector behind the park assist sensor as this will also cause a Short to Ground fault. With potential wiring issues addressed, the sensors must activate in order for the faults to go STORED. After all sensors are properly connected (you will likely hear a click once the connector is fully seated on the sensor), turn off the engine, wait 10 seconds, turn on the engine and then place the vehicle in REVERSE so that the sensors activate. The faults will go STORED.

25-001-162018-05-21. Service bulletin. FUEL SYSTEM, DIESEL. Diagnosing A Urea Module That Is Exposed To Diesel Fuel This bulletin involves discussing what will happen to the rubber material used in the urea pump when exposed to diesel fuel. 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.
08-067-162018-05-21. Service bulletin. ELECTRICAL SYSTEM. Ignition Node Module Replacement This bulletin involves replacing the ignition node module. Some customers may experience a no start issue when turning the key fob in the ignition node module(Fig. 1).
