Service bulletins for the 2014 Ram 5500

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.

21015142023-01-17. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. Transmission Shift Enhancements
S17090000102023-01-09. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Customer complaints may include abnormal engine noise, rough idle, lack of power, misfire. Upon investigation, it may be found that there is excessive camshaft lobe wear/lifter wear (roller failure) on one or more cam lobes and that camshaft/lifter replacement is necessary.
21-015-142022-08-29. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; POWER TRAIN. Flash: Transmission Shift Enhancements This bulletin involves selectively erasing and reprogramming the Transmission Control Module (TCM) with new software. The customer may indicate that they experience a harsh 2 - 1 downshift.
18-004-142022-08-29. Service bulletin. EXTERIOR LIGHTING; BACK OVER PREVENTION; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ELECTRICAL SYSTEM. Flash: Malfunction Indicator Lamp (MIL) Illumination. Includes Various Driveability Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. A small number of customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the Technician may find that the following Diagnostic Trouble Codes (DTC?s) have been set: (Further improvements over what was released in SB 18-004-14) (applies only to DD/DP vehicles) (applies only to DD/DP vehicles) P2066 - Fuel Level Sensor 2 Performance (applies only to DJ/D2 vehicles) P0441 - Evap Purge System Performance P2504 - Charging System Output High P04D0 - Cooled EGR Temperature Sensor Circuit Low P04D1 - Cooled EGR Temperature Sensor Circuit High
18-042-202020-06-22. Service bulletin. FUEL SYSTEM, DIESEL; ELECTRICAL SYSTEM; EQUIPMENT; ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Flash: Powertrain Control Module (PCM) Updates This bulletin involves reprogramming the Engine Control Module/Powertrain Control Module (ECM/PCM) with the latest available software. Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find that one or more of the following DTCs have been set:There will be a choice between two calibrations. One for vehicles that utilize an ammonia sensor and one for vehicles that have had the ammonia sensor removed. Be sure to select the correct software based on vehicle configuration.Improvements to prevent or reduce MIL illumination when no defect is present for:P2201 - Aftertreatment Nox Sensor Circuit Performance - Bank 1 Sensor 1(Ammonia delete systems only). P229F - Aftertreatment NOx Sensor Circuit Performance - Bank 1 Sensor 2. P20EE - SCR NOx Catalyst Efficiency Below Threshold - Bank 1(New Improvements for ammonia delete systems only). P202E - Diesel Exhaust Fluid (DEF) Reductant Injector Performance(New Improvements for ammonia delete systems only). P218F - Reductant No Flow Detected. P1C55 - NOx Sensor Intermittent - Bank 1 Sensor 1. U0001 - CAN C Bus. P229E - NOx Sensor Circuit - Bank 1 Sensor 2(Non-ammonia delete systems only). U059F - Invalid Data Received From NOx Sensor "B"(Non-ammonia delete systems only). P22A7 - NOx Sensor Heater Circuit Performance - Bank 1 Sensor 2(Non-ammonia delete systems only). P2459 - Diesel Particulate Filter Regeneration Too Frequent. P242F - Diesel Particulate Filter Restriction - Ash Accumulation. P205E - (Diesel Exhaust Fluid) Reductant Tank Temperature Sensor Circuit Intermittent (setting when the block heater is plugged in). P20E8 - (Diesel Exhaust Fluid) Reductant Pressure Too Low. U110E - Lost Ambient Temperature Message. U3017 - Control Module Timer/Clock Performance. P0087 - Fuel Rail Pressure Too Low. P0544 - Exhaust Gas Temperature Sensor Circuit - Sensor 1/1. P2281 - Air Leak Between MAF And Throttle Body.
