Service bulletins for the 2011 Dodge Ram

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.

25-002-132018-02-21. Service bulletin. FUEL SYSTEM, DIESEL. MIL Illumination Due To P1C56 - NOx Sensor Intermittent - Bank 1 Sensor 2 This bulletin involves verifying excessive Diesel Exhaust Fluid (DEF) deposits in the decomposition tube collected and if present, replacing the Catalytic Converter Shield with a ?clam shell? shield with a metal exterior.This repair is to be performed in addition to diagnostics available in DEALERCONNECT > Service > Repair Information > TechCONNECT > 28 - DTC-Based Diagnostics > MODULE, Powertrain Control (PCM), DD/DP - Chassis Cab > Diagnosis and Testing > P1C56 - NOx SENSOR INTERMITTENT - BANK 1 SENSOR 2 Customer may experience MIL illumination. Further investigation by the technician may find P1C56 - NOx Sensor Intermittent - Bank 1 Sensor 2 is set active or stored.This condition may be caused by insufficient heat retention in the exhaust at or near the DEF doser.

18-066-16 REV. A2017-11-03. Service bulletin. FUEL SYSTEM, GASOLINE; POWER TRAIN; ELECTRICAL SYSTEM. Flash: Powertrain Diagnostic And System Enhancements This bulletin involves reprogramming the Powertrain Control Module (PCM) with updated software. Some customers may describe one or more of the following: MIL Illumination Upon further investigation the technician may find that the following Diagnostic Trouble Codes (DTCs) have been set: · P2096 - Downstream Fuel Trim System 1 Lean (5.7L Engines). · P2097 - Downstream Fuel Trim System 1 Rich (5.7L Engines). · P2098 - Downstream Fuel Trim System 2 Lean (5.7L Engines). · P2099 - Downstream Fuel Trim System 2 Rich (5.7L Engines). Drivability Improvements: · MIL Lamp without DTC Active - Permanent Fault Code Issue (fix permanent fault code retention). · ASD Relay (to improve fuel pump relay initialization at key on). · Fuel pump relay operation at key on. · Engine seems to lacks power at high engine RPMs (5.7L and 4.7L Engines). · Shudder or shake condition on wide open throttle stab during downshift event (5.7L and 4.7L Engines). · EVAP Diagnostic Enhancements. This diagnostic routine will be disabled while the vehicle is in decel fuel shut off mode.(3.7L/4.7L Engines only). · Audible knock sound on WOT launches (DJ/DD 5.7L Engines only). Transmission Improvements: · High engine RPMs needed before vehicle will upshift from 3rd to 4th. (5.7L and 4.7L Engines). · Harsh 1st to 2nd gear upshift (5.7L and 4.7L Engines). · Unexpected or busy downshift while coasting between 45-48 mph (72-77 kmh) (DS 5.7L Engines only).
