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. These improvements are separated into the following categories. WARNING: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 Unnecessary Malfunction Indicator Lamp (MIL) Illumination For The Following Diagnostic Trouble Codes (DTCs). These DTCs Are Currently Set As A One Trip Fault And Should Be A Two Trip Fault: ? P0201 - P0206 - Fuel Injector X Circuit/Open. ? P049D - EGR Control Position Exceeded Learning Limit. These DTCs Are Currently Set As A Two Trip Fault And Should Have Been A One Trip Fault: ? U12A4 - Lost Communication With Ammonia Sensor. Improvements To Prevent Or Reduce Unnecessary Malfunction Indicator Lamp (Mil) Illumination For: ? P205E - (Diesel Exhaust Fluid) Reductant Tank Temperature Sensor Circuit Intermittent (setting when the block heater is plugged in). ? U110E - Lost Ambient Temperature Message. ? P20E8 - (Diesel Exhaust Fluid) Reductant Pressure Too Low. ? P2281 - Air Leak Between MAF and Throttle Body. ? U3017 - Control Module Timer/Clock Performance. ? U1421 - Implausible Ignition Key Off Time Received. ? P0128 - Thermostat Rationality. In cold ambient temperatures. ? P0087 - Fuel Rail Pressure Too Low. ? P0544 - Exhaust Gas Temperature Sensor Circuit - Bank 1 Sensor 1. ? P2002 - Diesel Particulate Filter Efficiency Below Threshold. ? P061A - Level 2 Torque Performance. ? P0234 - Turbocharger Overboost condition. ? P026A - Charge Air Cooler Efficiency Below Threshold. ? P0299 - Manifold Pressure Sensor Out of Range Low. ? P0544 - Exhaust Gas Temperature (EGT
