Auto Repair 2009 Ford F-Super Duty 6.4L—Diesel Calibration Updates
ISSUE Some 2009 F-Super-Duty 250-550 vehicles and equipped with a 6.4L diesel engine may require a calibration update which will cover several different concerns. ACTION Follow the Service Procedure steps to correct the condition. NORMAL OPERATING CHARACTERISTICS – EXHAUST SYSTEM REGENERATION This document provides additional information on the conditions of normal operation while the vehicle is in the exhaust filter regeneration process. These are normal conditions and do not require repair. For most driving conditions, normal exhaust filter regeneration will begin anywhere from 100-600 miles (161-966 km) from the completion of the last regeneration cycle. Each occurrence will last from 10-40 minutes.
The exhaust filter regeneration process will not initiate or may be terminated when: • The vehicle is stopped at idle for more than 5 minutes in gear. • The vehicle is operated in Power Take Off (PTO) mode. • Stationary Elevated Idle Control (SEIC) is engaged. • The gear selector is placed in Park or Neutral. Vehicle characteristics change during the exhaust filter regeneration process: • Some white smoke in cold ambient temperatures is normal. The amount of white smoke during this time will be increased during exhaust filter regeneration. • The engine’s peak power is modestly limited during regeneration. • Engine responsiveness may be slightly different than normal operation during regeneration.
• Exhaust smell may be noticed during the exhaust filter regeneration process – especially on new vehicles. • The powertrain sound will be different during exhaust filter regeneration including air induction noise, combustion noise, flutter on deceleration or shut down. SERVICE PROCEDURE Reprogram the Powertrain Control Module (PCM) to the latest calibration before performing diagnostics and clear all diagnostic trouble codes (DTCs) after programming. For DTC’s generated after reprogramming, follow normal diagnostic service procedures. Reprogram the PCM to the latest calibration using Integrated Diagnostic System (IDS) release 61.19 and higher or 62.07 and higher. This new calibration is not included in the VCM 2009.7 DVD. Calibration files may also be obtained at www.motorcraft.com. When reprogramming the PCM on automatictransmission equipped vehicles the Transmission Control Module (TCM) will also automatically be reprogrammed to the latest level.
