Summary

Flash: 3.0L Diagnostic And System Improvements This bulletin involves reprogramming the Engine Control Module (ECM) with the latest available software. A small number of customers may experience a Malfunction Indicator Lamp (MIL) Illumination. Upon further investigation a technician may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the ECM memory. ? P00AF-00 - Turbocharger Boost Control Module A Performance. ? P226C-00 - Turbocharger Boost Control Slow Response. ? P2458-00 - Diesel Particulate Filter Regeneration Duration. ? P2459-00 - Diesel Particulate Filter Regeneration Frequency. ? P2463-00 - Diesel Particulate Filter - Soot Accumulation. ? P22FA-00 - NOx Sensor Performance Slow Response High to Low Bank 1 Sensor 1. ? P203B-00 - Reductant Level Sensor 1 Circuit Performance. ? P203E-00 - Reductant Level Sensor 1 Circuit Intermittent-Erratic. ? P0401-00 - EGR System Performance. ? P0402-00 - Exhaust Gas Recirculation Flow Excessive Detected. ? P04FB-00 - Crankcase Ventilation Hose Connection Sensor Range/Performance. ? P04E2-00 - Crankcase Ventilation Hose Connection Sensor Circuit Low. ? P051B-00 - Crankcase Pressure Sensor Circuit Range/Performance. ? P051C-00 - Crankcase Pressure Sensor Circuit Low. ? P051D-00 - Crankcase Pressure Sensor Circuit High. ? P04DB-00 - Crankcase Ventilation System Disconnected. ? P04FC-00 - Crankcase Ventilation System Performance. ? P011B-00 - Engine Coolant Temperature / Intake Air Temperature Correlation. ? P04D9-00 - Closed Loop EGR Control At Limit Flow Too Low. ? P250A-00 - Low Oil Pressure Active ? P04DA-00 - Closed Loop EGR Control At Limit Flow Too High. In addition, this system enhancement will improve the detection capability for "Insufficient Diesel Exhaust Fluid (DEF) Quality" as well as corrects a condition where incorrect Glow Plugs were being identified when Glow Plug DTCs were set for cylinders 2, 3, and 4.
