Super Duty diesel dilemma

Some 6.0L equipped 2004 Ford F-350 Super Duty trucks built between 9-29-2003 and 4-28-2004 may exhibit low rpm, buck/jerk, miss and/or stumble after deceleration down a long grade with the cruise control engaged.

To address this concern, reprogram the powertrain control module (PCM), fuel injection control module (FICM) and transmission control module (TCM) to the latest calibration using WDS release B31.11 or higher. Calibration files may also be obtained at

To update calibrations using WDS, select Module Programming>Module Reprogramming>PCM and ensure that the vehicle is properly identified. This will enable WDS to update the FICM, PCM and TCM with the appropriate calibration.

This calibration update also includes improvements for the electronic throttle control (ETC) pedal, fuel pump diagnostics and enhancements to prevent false DTCs when using the WDS data logger output state control function.
