Flash: 6.7L Diagnostic And System Improvements This bulletin involves reprogramming the Engine Control Module (ECM) with the latest available software. Several software improvements are available for vehicles equipped with a Cummins 6.7L turbo diesel. NOTE: There will be a choice between two 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. Improvements to prevent or reduce Malfunction Indicator Lamp (MIL) illumination when no defect is present for the following Diagnostic Trouble Codes (DTCs): · **P20EE - Selective Catalytic Reduction (SCR) NOx Catalyst Efficiency Below Threshold - Bank 1 (For ammonia sensor equipped vehicles).** · P1C55 - NOx Sensor Intermittent - Bank 1 Sensor 1 (For ammonia sensor deleted systems only). · P218F - Reductant No Flow Detected. · P242F - Diesel Particulate Filter Restriction - Ash Accumulation. · U110E - Lost Ambient Temperature Message. · P205E - (Diesel Exhaust Fluid) Reductant Tank Temperature Sensor Circuit Intermittent (setting when the block heater is plugged in). · P20E8 - (Diesel Exhaust Fluid) Reductant Pressure Too Low. · U3017 - Control Module Timer/Clock Performance. · U1421 - Implausible Ignition Key Off Time Received. · P2281 - Air Leak Between MAF And Throttle Body. Other Software Improvements: · Ambient Air Temperature Improvements. · Operational Improvement for Dual Alternators. · Selective Catalytic Reduction (SCR) Efficiency scan tool test improvement. · Fuel Filter Minder calibration changes. · wiTECH Fuel Pressure Override and Fuel System Run Up test improvements. · Exhaust Gas Recirculation (EGR) system improvement to help prevent freeze up. · Diesel Exhaust Fluid (DEF) system enhancement during stationary regeneration.
