Service bulletins for the 2014 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.

08-001-142018-05-21. Service bulletin. ELECTRICAL SYSTEM; SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE. Flash: Activate The Disable Feature For Hill Start Assist And PTO Enhancement This bulletin involves updating the Anit-Lock Brake System (ABS) module software. No DTC will be found.
18-028-16 REV. A2018-05-07. Service bulletin. ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Flash: 6.7L Diagnostic And System Improvements This bulletin involves selectively erasing and reprogramming the Engine Control Module (ECM) with new software. Several software improvements are available for vehicles equipped with a Cummins 6.7L turbo Diesel. NOTE: There will be a choice between 2 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. Prevent or reduce Malfunction Indicator Lamp (MIL) illumination when no defect is present for the following Diagnostic Trouble Codes (DTCs). These faults have been changed from a one trip fault to a two trip fault: · P0201 - P0206 - Fuel Injector X Circuit/Open Fault Codes. · P049D - Exhaust Gas Recirculation (EGR) Control Position Exceeding Learning Limit. Improvements to prevent or reduce Malfunction Indicator Lamp (MIL) illumination when no defect is present for: · **P229E - NOx Sensor Circuit - Bank 1 Sensor 2 (For non-ammonia delete systems only). · P229F - Aftertreatment NOx Sensor Circuit Performance - Bank 1 Sensor 2 (For non-ammonia delete systems only). · P22A7 - NOx Sensor Heater Circuit Performance - Bank 1 Sensor 2 (For non-ammonia delete systems only). · U059F - Invalid Data Received From NOx Sensor "B" (For non-ammonia delete systems only). · P2459 - Diesel Particulate Filter Regeneration Too Frequent. · P218F - Reductant No Flow Detected. · P242F - Diesel Particulate Filter Restriction - Ash Accumulation.** · P1C55 - NOx Sensor Intermittent - Bank 1 Sensor 1 (For ammonia delete systems only). · 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.
18-096-162018-02-21. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. 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). ·
