07-9-10 6.4L - PTO/BCP - DISENGAGES WITH VEHICLE BODY MOVEMENT
Publication Date: May 1, 2007
FORD: 2008 F-450, F-550
Some 2008 F450/550 Super Duty vehicles equipped with 6.4L diesel engine may lose power take-off (PTO) or battery charge protection (BCP) function with any small body movement. This includes movement as light as opening a door, or stepping on the bumper. This concern is only on vehicles using the Ford stationary elevated idle control (SEIC) to provide the required engine speed increase and its circuit links to PTO engagement and battery state. When this occurs the engine speed returns to base idle of 650 RPM, and any PTO and BCP circuit links are disconnected. In normal diesel engine operation SEIC automatically reactivates after 3 seconds if no disabling condition remains present, returning to its preset target speed, and re-enabling the PTO or BCP function.
Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 48.12 and higher or 49.2 and higher. This new calibration is not included in the VCM 2007.5 DVD.This calibration filters out small vehicle speed signals shutting down SEIC. Calibration files may also be obtained at www.motorcraft.com
. Vehicle road speed signal is an SEIC disabler, and this calibration makes that signal less sensitive.
