FLASH: Engine Systems and PTO Enhancements This bulletin involves selectively erasing and reprogramming the Engine Control Module (ECM) with new software. Cab chassis trucks equipped with a 6.7L Cummins diesel have a number of software improvements available. This latest Service Bulletin (SB) will include:Improvements To Prevent Unnecessary Malfunction Indicator Lamp (MIL) Illumination For: P0524 - ENGINE OIL PRESSURE SENSOR CIRCUIT LOW P051B - CRANKCASE PRESSURE SENSOR CIRCUIT RANGE/PERFORMANCE P20EE - SCR NOx CATALYST EFFICIENCY BELOW THRESHOLD - BANK 1 U010E - LOST COMMUNICATION WITH DIESEL EXHAUST FLUID CONTROL UNIT P2609 - INTAKE AIR HEATER SYSTEM PERFORMANCE P061A - ETC LEVEL 2 TORQUE PERFORMANCE P1123 - POWER TAKE OFF SYSTEM MONITOR CONTROL ERROR P2579 - TURBOCHARGER SPEED SENSOR CIRCUIT PERFORMANCE P2453 - DIESEL PARTICULATE FILTER PRESSURE SENSOR A CIRCUIT PERFORMANCE U059F - INVALID DATA RECEIVED FROM NOx SENSOR "B" P20EE - SCR NOx CATALYST EFFICIENCY BELOW THRESHOLD - BANK 1 Vehicles with DTC P20EE set in conditions other than highway speed and/or high load drive cycles should have normal diagnostics performed Enhanced Diagnostics For:Variable Geometry Turbocharger.Fuel level sensor.Misfire without MIL illuminationOther Updates:Too frequent regeneration readiness improvement Correct CAC out voltage in WiTech Add ability to read EMP sensor value in WiTech Display correct crankcase pressure in WiTech Display correct EGR position in WiTech Display correct alternator voltage in WiTech Improve idle shutdown messages - extra message removed Low Diesel Exhaust Fluid (DEF) level EVIC messaging strategy changes. Diesel Exhaust Fluid (DEF) system tampering EVIC messaging strategy changes. Oil change monitor - updated for easier reset (same basic procedure, easier to reset). Scan tool display updates.Enable mobile PTO capability. Correct operation of remote PTO. Correct EVIC messaging related to DEF level reporting System robustness improveme
