• 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 will 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 engine 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 rectified. For example, the E362-
1Engine 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 perform these functions. In order to obtain factory
passwords, proceed as if you already have the
password. If factory passwords are needed, the
electronic service tool will request the factory
passwords and the electronic service tool will display
the information that is required to obtain the
passwords.

Flash Programming
Flash Programming
– A method of loading a flash
file into the Electronic Control Module (ECM)
The electronic 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.
Note:
If you do not have the part number for the flash
file, use
“
PTMI
”
on the Perkins Intranet.
Note:
You must have the engine serial number in
order to search for the part number for the flash file.
2.
Connect the electronic service tool to the service
tool connector.
3.
Turn the keyswitch to the ON position. Do not start
the engine.
4.
Select
“
WinFlash
”
from the
“
Utilities
”
menu on
the electronic service tool.
Note:
If
“
WinFlash
”
will not communicate with the
ECM, refer to Troubleshooting, “Electronic Service
Tool Will Not Communicate with ECM”.
5.
Program the flash file into the ECM.
a.
Select the engine ECM under the
“
Detected
ECMs
”
.
b.
Press the
“
Browse
”
button in order to select
the part number of the flash file that will be
programmed into the ECM.
c.
When the correct flash file is selected, press
the
“
Open
”
button.
d.
Verify that 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
completed.
6.
Start the engine and check for proper operation.
7.
Access the
“
Configuration
”
screen under the
“
Service
”
menu in order to determine the
parameters 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 tattletale of 0, program that parameter.
