Flash Electronically Erasable Programmable Read Only Memory: Description

Flash Electronically Erasable Programmable Read Only Memory (EEPROM) is contained in an Integrated Circuit (IC) inside of PCM. The EEPROM contains the vehicle strategy and any calibration information specific to vehicle. The IC is reprogrammable and at times it may become necessary to reprogram or reflash the entire contents. This is usually due to an after production strategy change or the Vehicle Identification (VID) area has been previously reprogrammed and has reached its limit. The VID block can be tailored to accommodate various hardware changes made since vehicle production. This procedure can only be performed using Ford's Service Bay Technical System (SBTS) or equivalent.

A replacement PCM will have a label stating PROGRAMMING REQUIRED. This indicates that it is necessary to retrieve VID data from the original PCM before removing PCM from vehicle. This procedure can be performed using New Generation Star (007-00500) tester or equivalent. If original PCM is nonfunctional, it will be necessary to manually reprogram VID block. This procedure can only be performed using Ford's Service Bay Technical System (SBTS).

  1. To perform this procedure New Generator Star (NGS) tester, Ford Service Function (FSF) card and NGS Flash Cable (007-00531) must be used. Plug flash cable into NGS tester. Plug other end of flash cable into Data Link Connector (DLC). From the NGS tester main menu, select SERVICE BAY FUNCTIONS, POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
  2. NGS tester display should show 2 selections. The first selection is for the old Powertrain Control Module (PCM) information to be retrieved and stored. The second selection is for restoring new PCM with information that has been retrieved from the old PCM. Follow NGS tester display instructions or refer to instruction sheet included with FSF card. If Vehicle Identification (VID) block has been reprogrammed previously, NGS tester will display a message indicating the need to reflash entire Integrated Circuit (IC). This procedure can only be performed using Ford's Worldwide Diagnostic System (WDS).
