Flash: Diagnostic and System Improvements This bulletin involves selectively erasing and reprogramming the Engine Control Module (ECM) with new software.Trucks exhibiting any DTC related to Oxygen Sensor, Oxygen Sensor Module or communication to the Oxygen Sensor Module also require that Service Bulletin?s 25-004-12 (or later bulletin) must be performed (if not previously performed). Pick up trucks equipped with a 6.7L Cummins diesel have a number of software improvements/enhancements available. This SB will include improved robustness for DTC's: P2000 - NOX ABSORBER EFFICIENCY BELOW THRESHOLD P1451 - DIESEL PARTICULATE FILTER SYSTEM PERFORMANCE P0101 - MASS AIR FLOW SENSOR "A" CIRCUIT PERFORMANCE P046C - EGR POSITION SENSOR PERFORMANCE P049D - EGR CONTROL POSITION EXCEEDED LEARNING LIMIT P051B - CRANKCASE PRESSURE SENSOR CIRCUIT RANGE/PERFORMANCE P2002 - DIESEL PARTICULATE FILTER EFFICIENCY BELOW THRESHOLD P2262 - TURBOCHARGER BOOST PRESSURE NOT DETECTED - MECHANICAL P2609 - INTAKE AIR HEATER SYSTEM PERFORMANCE P245B - EGR COOLER BYPASS STATUS LINE INTERMITTENTVehicles flashed to address the above codes should be driven and repair validated. If code(s) return, follow diagnostic procedures available in DealerCONNECT/TechCONNECT.Improvements other than DTC robustness or enhancements: O2 Sensor cleaning cycle Correct Charge Air Cooler (CAC) out voltage reading in WiTech Improve idle shutdown messages Add ability to read Exhaust Manifold Presure (EMP) sensor value in WiTech Display correct Exhaust Gas Recirculation (EGR) position in WiTech Make Grid Heater off time selectable in WiTec Display correct alternator voltage in WiTech Turn Low Voltage Idle Up Off MIL on with no DTC Ability to read EGR valve gap on wiTECH Erroneous, brief brake lamp flash at key onSecure Bootloader softwareIf the Engine Control Module (ECM) does not have a calibration installed, or has an unapproved calibration installed then the ECM will
