Flash: 3.0L Powertrain Diagnostic And System Enhancements This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest available software. A small number of customers may experience bucking under hard acceleration. In addition other customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation a technician may find one of more of the following Diagnostic Trouble Codes (DTCs) set in the PCM memory: ? P1296-00 - EGR Slow Response - Increasing Flow. ? P249C-00 - Excessive Time To Enter Closed Loop Reductant Injection Timing Control. ? P20C2-00 - Reductant Heater 3 Control Circuit Performance. ? P24A4-00 - Particulate Filter Restriction - Soot Accumulation Too High. ? P24D1-00 - Particulate Matter Sensor Regeneration Incomplete. ? P1288-00 - NOX Sensor 1/2 Zero Offset Too High. ? P1289-00 - NOx Sensor 1/2 Zero Offset Too Low. ? P2463-00 - Diesel Particulate Filter - Soot Accumlation . ? U0422-00 - Implausible Data Received From Body Control Module. ? U3017-00 - Control Module Timer/Clock Performance. ? P2196-00 ? O2 Sensor 1/1 Stuck Rich. ? P1E0C-00 ? Empty Fuel Tank. ? P2237-00 ? O2 Sensor 1/1 Pump Cell Current Circuit Open. ? P1297-00 ? EGR Slow Response - Decreasing Flow. ? P0420-00 ? Catalyst Efficiency (Bank 1). ? P24AF-00 ? Particulate Matter Sensor Circuit Performance. ? P26AB ? Engine Coolant Bypass Valve Stuck. ? P204F-00 ? Reductant System Performance. ? P20E9-00 ? Reductant Pressure Too High. ? P2002-00 ? Diesel Particulate Filter Efficiency Below Threshold. ? P2299-00 ? Brake Pedal Position/Accelerator Pedal Position Incompatible. ? P208B-00 ? Reductant Pump 1 Control Performance. ? P016A-00 ? Excessive Time To Enter Closed Loop Air/Fuel Ratio Control. Upon further investigation a technician may find the following Diagnostic Trouble Code (DTC) set in the TCM memory: ? U1424-00 - Implausible Engine Torque Signal Received
