NOTE: There are 2 different methods to erase the transponder key code: using
ignition switch, or using LEXUS scan tool. All other master and sub-key
codes are deleted. When using ignition key which was used before
deleting, it is necessary to register the code again.
NOTE: Ensure driver's door is closed and ignition key is not inserted in ignition
switch.
CAUTION: DO NOT crank engine before replacement PCM is programed to
immobilizer system or PCM will be severely damaged. If test procedures

PROGRAMMING POWERTRAIN CONTROL MODULE
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
1. 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.
2. 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).
KEY REPLACEMENT OR ADDITION
require replacement of PCM on a vehicle equipped with immobilizer
system, vehicle must be sent to authorized Mazda dealer to have
replacement PCM programed.
NOTE: Before performing PCM programming procedure, check for any applicable
Technical Service Bulletins (TSBs) that may apply to vehicle application.
NOTE: If using a generic scan tool, follow scan tool manufacturer's instructions
to perform this procedure.
