PRINCIPLES OF OPERATION
Newly released modules require configuration after being installed on the vehicle. All configurable modules will be packaged in a kit which contains a warning label and a multi-language sheet reemphasizing requirements to configure replacement modules. Powertrain Control Module (PCM) has to be standard J1962 lead.
Description
Flash 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 it may become necessary to reprogram or reflash the entire contents. This is usually due to an after production strategy change or the Flash 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) 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) scan tool or equivalent. See FLASH VEHICLE IDENTIFICATION BLOCK PROCEDURE . If original PCM is damaged, nonfunctional or incapable of communicating, it will be necessary to manually reprogram VID block. This procedure can only be performed by contacting the "AS BUILT" data center for programming information.
Flash Vehicle Identification Block Procedure
Note. If using a generic scan tool, follow scan tool manufacturer's instructions to perform this procedure.
- To perform this procedure NGS scan tool, 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, POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
- Scan tool display should show 2 selections. The first is selection is for old 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 scan tool display instructions or refer to instruction sheet included with FSF card. If Flash Vehicle Identification (VID) Block has been reprogrammed previously, scan tool 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).
Readiness code must be generated whenever ECM memory is cleared, ECM loses battery voltage or is replaced. Readiness code appears as an 8-digit display in diagnostic function MEASURING VALUE BLOCK 086, display field 1 of scan tool. Each of the 8 digits is related to a specific exhaust related system. During a test sequence OBD system checks function of each of the 8 systems. OBD system checks components and generates Readiness Code at regular intervals during normal driving.
Note. Not all eight diagnostic functions in Readiness Code are used. (Схема №9)
