- Summary
- Flash: Powertrain Control Module (PCM) Updates This bulletin involves reprogramming the Engine Control Module/Powertrain Control Module (ECM/PCM) with the latest available software. The customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find one or more of the following DTCs.P20EE - SCR NOx Catalyst Efficiency Below Threshold - Bank 1. P1C54 - SCR NOx Catalyst Missing. P229F - Aftertreatment NOx Sensor Circuit Performance - Bank 1 Sensor 2. P207F - Reductant Quality Performance. P2002 - Diesel Particulate Filter Efficiency Below Threshold. P2201 - Aftertreatment NOx Sensor Circuit Performance - Bank 1 Sensor 1. P202E - (Diesel Exhaust Fluid) Reductant Injector Performance. P0300 - Multiple Cylinder Misfire. P0301-00 - Cylinder 1 Misfire. P0302-00 - Cylinder 2 Misfire. P0303-00 - Cylinder 3 Misfire. P0304-00 - Cylinder 4 Misfire. P0305-00 - Cylinder 5 Misfire. P0306-00 - Cylinder 6 Misfire. P249E - Closed Loop SCR Reductant Injection Control At Limit - Flow Too High. P0401 - EGR System Performance. P0128 - Thermostat Rationality. P218F - Reductant No Flow Detected. U0001-00 - CAN C BUS. P24A5 - EGR Cooler Bypass Bank 1 Control Stuck. P1451 - Diesel Particulate Filter System Performance. P229E - NOx Sensor Circuit - Bank 1 Sensor 2. P2281 - Air Leak Between MAF and Throttle Body. P0218 - Transmission High Temperature Operation Activated (68RFE Only). P0868 - Line Pressure Low, MIL Action (68RFE Only). U110E - Lost Ambient Temperature Message. P205E - (Diesel Exhaust Fluid) Reductant Tank Temperature Sensor Circuit Intermittent (setting when the block heater is plugged in). The following Diagnostic Trouble Codes (DTCs) have been changed from a one trip fault to a two trip fault:P0421 - Catalyst 1 Efficiency Below Threshold Bank 1. P2280 - Air Flow Restriction / Leak Between Air Cleaner And MAF. P203C - (Diesel Exhaust Fluid) Reductant Level Sensor Circuit Low.
