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 a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find one or more of the following Diagnostic Trouble Codes (DTCs): ? P0299 - Turbocharger Underboost ? P226C - Turbocharger Boost Control Slow Response ? P0181 - Fuel Temperature Sensor Circuit Low ? P2BA9 - NOx Exceedence - Insufficient Reductant Quality ? P0401 - EGR System Performance ? P00AF - Turbocharger Boost Control Module A Performance ? P203B - Reductant Level Sensor 1 Circuit Performance ? P203E - Reductant Level Sensor 1 Circuit Intermittent-Erratic ? P22FA - NOx Sensor Performance Slow Response High to Low Bank 1 Sensor 1 ? P2458 - Diesel Particulate Filter Regeneration Duration ? P2459 - Diesel Particulate Filter Regeneration Frequency ? P2463 - Diesel Particulate Filter - Soot Accumulation ? P0402 - Exhuast Gas Recirculation Flow Excessive Detected ? P04FB - Crankcase Ventilation Hose Connection Sensor Range/Performance ? P04E2 - Crankcase Ventilation Hose Connection Sensor Circuit Low ? P051B - Crankcase Pressure Sensor Circuit Range/Performance ? P051C - Crankcase Pressure Sensor Circuit Low ? P051D - Crankcase Pressure Sensor Circuit High ? P04DB - Crankcase Ventilation System Disconnected ? P04FC - Crankcase Ventilation System Performance ? P011B - Engine Coolant Temperature / Intake Air Temperature Correlation ? P04D9 - Closed Loop EGR Control At Limit Flow Too Low ? P04DA - Closed Loop EGR Control At Limit Flow Too High In addition to the DTCs listed above, this software also corrects a condition where incorrect glow plugs were being identified when glow plug DTCs were set for cylinders 2, 3, and 4.
