•
Program a new Electronic Control Module (ECM).
When an ECM is replaced, the system configuration
parameters must be programmed into the new
ECM. A new ECM w
ill allow these parameters to
be programmed once without factory passwords.
After the initial programming, some parameters are
protected by
factory passwords.
•
Rerate the engine.
This may require changing the interlock code,
which is protected by factory passwords.
•
Clear engine events and certain diagnostic codes.
Most engin
e events require factory passwords in
order to clear the code from ECM memory. Clear
these codes only when you are certain that a fault
has been re
ctified. For example, the E362-1 Engine
Overspeed requires the use of factory passwords
in order to clear the code from ECM memory.
Since factory passwords contain alphabetic
characters, the electronic service tool must be
used to pe
rform these functions. In order to obtain
factory passwords, proceed as if you already have
the password. If factory passwords are needed,
the elec
tronic service tool will request the factory
passwords and the electronic service tool will
display the information that is required to obtain the
passwor
ds.

Flash Programming
Flas
h Programming – A method of loading a flash
file into the Electronic Control Module (ECM)
The e
lectronic service tool can be utilized to program
a flash file into the ECM. The programming transfers
the flash file from the PC to the ECM.
Flash Programming a Flash File
1. Obtain the part number for the new flash file.
No
te: If you do not have the part number for the flash
file, use “PTMI” on the Perkins Intranet.
No
te: You must have the engine serial number in
order to search for the part number for the flash file.
2. Co
nnect the electronic service tool to the service
tool connector.
3
.
T
urn the keyswitch to the ON position. Do not start
the engine.
4. Select “WinFlash” from the “Utilities” menu on the
electronic ser
vice tool.
Note: If “WinFlash” will not communicate with the
ECM, refer to T
roubleshooting, “Electronic Service
Tool Will Not Communicate with ECM”.
5. Program the fl
ash file into the ECM.
a. Select the engine ECM under the “Detected
ECMs”.
b. Press the “Browse” button in order to select
the part num
ber of the flash file that will be
programmed into the ECM.
c. When the co
rrect flash file is selected, press
the “Open” button.
d. Verify tha
t the “File Values” match the
application. If the “File Values” do not match
the application, search for the correct flash file.
e. When the correct flash file is selected, press
the “Begin Flash” button.
f. The electronic service tool will indicate
when programming has been successfully
complet
ed.
6. Start the engine and check for proper operation.
7. Access the “Configuration” screen under the
“Service” menu in order to determine the
parame
ters that require programming. Look under
the “Tattletale” column. All of the parameters
should have a tattletale of 1 or more. If a parameter
has a t
attletale of 0, program that parameter.
“WinFlash” Error Messages
If you receive any error messages during
programming, click on the “Cancel” button in order
to st
op the process. Access the information about
the “ECM Summary” under the “Information” menu.
Ensure that you are programming the correct flash
file f
or your engine.

Injecto r Trim File
The electronic service tool is used to load the injector
trim files into the Electronic Control Module (ECM).
The i njector trim files must be loaded into the ECM if
any of the following conditions occur:
•
An electronic unit injector is replaced.
