原廠摘要

以下為英文原文

Flash: Powertrain Control Module (PCM) Updates This bulletin involves reprogramming the Engine Control Module/Powertrain Control Module (ECM/PCM) with the latest available software. Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find that one or more of the following DTCs have been set: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 MIL illumination when no defect is present for:P2201 - Aftertreatment Nox Sensor Circuit Performance - Bank 1 Sensor 1(Ammonia delete systems only). P229F - Aftertreatment NOx Sensor Circuit Performance - Bank 1 Sensor 2. P20EE - SCR NOx Catalyst Efficiency Below Threshold - Bank 1(New Improvements for ammonia delete systems only). P202E - Diesel Exhaust Fluid (DEF) Reductant Injector Performance(New Improvements for ammonia delete systems only). P218F - Reductant No Flow Detected. P1C55 - NOx Sensor Intermittent - Bank 1 Sensor 1. U0001 - CAN C Bus. P229E - NOx Sensor Circuit - Bank 1 Sensor 2(Non-ammonia delete systems only). U059F - Invalid Data Received From NOx Sensor "B"(Non-ammonia delete systems only). P22A7 - NOx Sensor Heater Circuit Performance - Bank 1 Sensor 2(Non-ammonia delete systems only). P2459 - Diesel Particulate Filter Regeneration Too Frequent. P242F - Diesel Particulate Filter Restriction - Ash Accumulation. 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. U110E - Lost Ambient Temperature Message. U3017 - Control Module Timer/Clock Performance. P0087 - Fuel Rail Pressure Too Low. P0544 - Exhaust Gas Temperature Sensor Circuit - Sensor 1/1. P2281 - Air Leak Between MAF And Throttle Body.
