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.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. U110E - Lost Ambient Temperature Message. 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: 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) Sensor Circuit - Bank 1 Sensor 1. P0562 - Battery Voltage Low. P20EE - SCR NOX Catalyst Efficiency Below Threshold - Bank 1. P2201 - Aftertreatment NOX Sensor Circuit Performance - Bank 1 Sensor 1. P24A5 - EGR Cooler Bypass Bank 1 Control Stuck. P2459 - Diesel Particulate Filter Regeneration Too Frequent. P249E - Closed Loop SCR Reductant Injection Control At Limit - Flow Too High.Other Updates:
