2005-2006 F-Super Duty

2005-2006 F-Super Duty vehicles built on or before 3/15/2006 equipped with a 6.0L engine may exhibit a buck/jerk condition in Low (L), first (1st), or second (2nd) in manual transmission vehicles, or in manual 1st, manual 2nd, or in tow-haul mode in first (1st) or second (2nd) on automatic transmission vehicles.

This concern occurs anywhere from 1800-2500 RPM at steady throttle or slight tip in. Concern will be more evident under a load, or while pulling a trailer.

This concern is more noticeable in manual transmission equipped vehicles.

ACTION:

Reprogram the powertrain control module (PCM) to the latest calibration using IDS or Ford J2534 release B41.11 and higher or B42.1 and higher.

This new calibration is not included in the B42 CD.

Service Information & Reprogramming

Software necessary to program electronic modules to the latest calibration level, perform module initialization (PATS), and set Programmable Parameters on Ford, Lincoln and Mercury vehicles.

Ford Module Programming (FMP) is a software application that allows subscribers to program electronic modules on Ford, Lincoln and Mercury vehicles. It can be used for:

Reprogramming emission-related (OBDII) modules on some vehicles manufactured in 1995 and all vehicles manufactured from 1996 to the present
Reprogramming or reconfiguring non-emission-related modules on many vehicles (UBP and MS-CAN not supported)

In addition, module initialization (PATS) functions such as Keycode Erase/Reprogram and PCM Parameter Reset can be done using this application.

J2534 Device using Ford Module Programming (FMP) can Reprogram and Configure most Modules.
