Description
Electronically Erasable Programmable Read Only Memory (EEPROM) is contained in an Integrated Circuit (IC) inside of Powertrain Control Module (PCM). The EEPROM contains the vehicle strategy and any calibration information specific to vehicle. The IC is reprogrammable and at times 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) block 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).
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. See FLASH VEHICLE IDENTIFICATION (VID) BLOCK PROCEDURE. 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).
Flash Vehicle Identification (VID) Block Procedure
- To perform this procedure NGS tester, Ford Service Function (FSF) card and NGS Flash Cable (007-00531) must be used. Plug flash cable into scan tool. Plug other end of flash cable into Data Link Connector (DLC). From the scan tool main menu, select SERVICE BAY FUNCTIONS, PCM-POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
- The NGS tester display should show 2 selections. The first is selection is for the old PCM information to be retrieved and stored. The second selection is for restoring the new PCM with information that has been retrieved from the old PCM. Follow 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 Service Bay Technical System (SBTS).
