Matching Security Identification Between Instrument Cluster & PCM (Type "B")
- Using New Generation Star (NGS) or Worldwide Diagnostic System (WDS) tester, perform instrument cluster self-test. If DTC B2139 is retrieved, go to next step. If DTC B2139 is not retrieved, system is okay at this time.
- Perform security access for instrument cluster. See KEY PROGRAMMING - SECURITY ACCESS PROCEDURE (TYPE "B"). Using NGS/WDS tester, select PARAMETER RESET command for instrument cluster. Using NGS/WDS tester, select PARAMETER RESET, PCM, ACTIVE COMMANDS, then KEEP ALIVE MEMORY RESET. Select CANCEL to return to previous screen. Turn ignition off. Disconnect NGS/WDS tester. Turn ignition switch to RUN position for 3 seconds. Turn ignition switch to LOCK position for 3 seconds. Repeat for a total of 3 times. Using NGS/WDS tester, perform instrument cluster self-test. If DTC B2139 is not retrieved, system is okay at this time. If DTC B2139 is retrieved, verify PCM calibration is correct for vehicle. If calibration is okay, replace instrument cluster and repeat this test. If DTC B2139 still exists, replace PCM.
Note. Security access must be granted to erase ignition keys, enable/disable spare key programming switch, or perform parameter resets for instrument cluster and PCM. This procedure has a 10-minute time delay prior to granting security access during which the New Generation Star (NGS) or Worldwide Diagnostic System (WDS) tester must remain connected to vehicle. After security access has been granted, security access command menu is displayed which offers various command options. Multiple security access commands can be executed (if necessary) prior to exiting security access command menu. Execution of all necessary security access commands prior to exiting command menu avoids the performance of an additional security access procedure and the associated 10-minute time delay.
Matching Security Identification Between Instrument Cluster & PCM (Type "C")

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 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. 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) or equivalent.
Note. If using a generic scan tool, follow scan tool manufacturer's instructions to perform FLASH VEHICLE IDENTIFICATION (VID) BLOCK PROCEDURE.
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 NGS tester. Plug other end of flash cable into Data Link Connector (DLC), located under instrument panel next to steering column. From the NGS tester main menu, select SERVICE BAY FUNCTIONS, PCM-POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
- NGS tester display should show 2 selections. The first selection is for old PCM information to be retrieved and stored. The second selection is for loading 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 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) or equivalent.
