2014 Ram 1500
TSB Document:
Affected Component: ELECTRICAL SYSTEM
- Summary
- Flash: MIL Illumination - Diagnostic and System Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. It also involves replacement of the Oxygen (O2) Sensor and cleaning or replacement of the Exhaust Gas Temperature (EGT) Sensor 1/2 if necessary depending on codes that have set. A small number of customers may experience an intermittent engine shudder or vibration which may not set a Diagnostic Trouble Code (DTC). In addition other customers may experience a Malfunction Indicator Lamp (MIL) illumination upon which the technician may find one or more of the following DTCs have been set: ? P2459-00 - Diesel Particulate Filter Regeneration Frequency. ? P0133-00 - O2 Sensor 1/1 Slow Response. ? P2084-00 - Exhaust Gas Temperature Sensor Circuit Performance - (1/2). ? P0171-00 - Fuel System 1/1 Lean. ? P0426-00 - Catalyst Temperature Sensor Circuit Performance (1/1). ? P0045-00 - Turbocharger Boost Control Circuit/Open. ? P0087-00 - Fuel Rail Pressure Too Low. ? P009A-00 - Intake Air Temperature/Ambient Air Temperature Correlation. ? P0128-00 - Thermostat Rationality. ? P0234-00 - Turbocharger Overboost Condition. ? P0420-00 - Catalyst Efficiency (Bank 1). ? P05F8-00 - Reductant Heater Control Module Performance. ? P050E-00 - Cold Start Engine Exhaust Temperature Too Low. ? P200A-00 - Intake Manifold Runner Performance - (Bank 1). ? P200B-00 - Intake Manifold Runner Performance - (Bank 2). ? P202E-00 - Reductant Injection Valve Circuit Performance. ? P20EE-00 - SCR NOX Catalyst Efficiency Below Threshold Bank 1. ? P204F-00 - Reductant System Performance. ? P2080-00 - Exhaust Gas Temperature Sensor Circuit Performance. ? P20BA-00 - Reductant Heater 1 Control Circuit Performance. ? P20BE-00 - Reductant Pressure Line Heater Control Circuit Performance. ? P20C2-00 - Reductant Heater 3 Control Circuit Performance. ? P20E9-00 - Reductant Pressure Too High.
