Service bulletins for the 2014 Ram 2500

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.

18-025-142018-06-11. Service bulletin. POWER TRAIN. Flash: Powertrain System Improvements/Enhancements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. The following powertrain system improvements/enhancements are included in this software release: ? Enhanced Automatic Oil Change Indicator(EAOCI) system enhancements that force the use of the severe duty cycle algorithm anytime the PCM is replaced. The vehicle duty cycle information used in the EAOCI calculation is stored in the PCM and cannot be recovered/transferred when the controller is replaced. As a result, the severe duty cycle is used in these scenarios to ensure the customer receives a timely oil change required message. ? Corrected a generic scan tool display issue regarding Mode 6 data accuracy. ? Improved transmission Quick Learn routine performance (Applies only to DJ vehicles)
BJA465972018-06-11. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; POWER TRAIN. Job aid - If you have a suspected TC shudder/vibration, check the Interactive Network for Service Bulletins for the vehicle you are working on. A test-drive snap shot may help you isolate the source of the issue.

18-004-142018-05-21. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Flash: Malfunction Indicator Lamp (MIL) Illumination 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: (applies only to vehicles equipped with a 66RFE sales code DFP) (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
18-096-162018-05-07. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. Flash: 6.4L Diagnostic And System Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. NOTE: **This bulletin contains optional software update that should only be used in situations where the customer is specifically complaining of a Drone Noise, Shudder, Pulsation, or Vibration under light throttle applications while vehicle is operating in MDS/ECO mode. There will be two separate software options displayed on the wiTECH flash tab. The software file released for this condition contains the verbiage ?OPTIONAL?. The other file is the standard software that does not contain improvements for the Drone/Shudder concern. If for some reason the customer finds this shudder improvement objectionable, the PCM software may be returned/reflashed to the standard version. Both software versions will address the remaining conditions noted in the bulletin. A small number of customers may experience a surge, shudder or pulsation type sensation when driving on smooth road surfaces at highway speeds of 64-129 km/h (40-80 mph).** During normal diagnostics a technician may find one or more of the following Diagnostic Trouble Codes (DTCs) present: · **P0335 - Crankshaft Position Sensor Circuit.** · P0300 - Multiple Cylinder Misfire, cold Idle misfire (DJ,D2 or DD vehicles only). · P030X - Cylinder Misfire (any cylinder). · P04D1 - Cooled EGR Temperature Sensor Circuit High. · P04D0 - Cooled EGR Temperature Sensor Circuit Low. · P2504 - Charging System Output High. · P0441 - Evap Purge System Performance. · P2066 - Fuel Level Sensor 2 Performance. · P0401 - EGR System Performance (DJ/D2 vehicles only). · P2096 - Downstream Fuel Trim System 1 Lean (DD/DP vehicles only). · P2098 - Downstream Fuel Trim System 2 Lean (DD/DP vehicles only). ·
