Programming Parameters

Note: “Test ECM Mode” can  only be activated if

the engine serial number  has not already been

programmed during normal operation of the ECM.

If the engine serial number is programmed and the

ECM is not in “Test ECM Mode”, the ECM can never

be used as a test ECM.

i03939853

Programming Parameters

6.  Use the “Copy Configuration” feature on  the

electronic service tool to program the test ECM.

The electronic service tool can  be used to view

certain parameters that can affect the operation of the

engine. The electronic service tool can also be used

to change certain parameters. The parameters are

stored in the Electronic Control Module (ECM). Some

of the parameters are protected from unauthorized

changes by passwords. Parameters that  can be

changed have a tattletale number.  The tattletale

number is incremented whenever a parameter  is

changed.

Note: If the “ECM Replacement” feature cannot be

used, program the test ECM with the values from the

“Customer Specified Parameters Worksheet” and the

values from the System Configuration Parameters.

7.  Program the engine serial number into the test

ECM.

Note: The “Test ECM Mode”  must be activated

before the engine serial number is programmed into

the ECM.

i03939990

Test ECM Mode

8.  Verify that the test ECM eliminates the fault.

When the “Test ECM Mode” is activated, an internal

timer sets a 24 hour clock. This clock will count down

only while the ECM is powered and the keyswitch

is in the ON position. After the  ECM has counted

down the 24 hour period, the ECM will exit the “Test

ECM Mode”. The parameters and the engine serial

number will be set.

“Test ECM Mode” is a feature in the software that

can be used to help troubleshoot an engine that may

have a fault in the Electronic Control Module (ECM).

This feature allows a standard ECM to be used as a

test ECM. This feature eliminates the need to stock

a test ECM.

If the test ECM eliminates the fault, the engine can

be released while the “Test ECM Mode” is still active.

1.  Search for the latest flash file for the engine.

Once an ECM has been activated in the “Test ECM

Mode”, the ECM will stay in the “Test ECM  Mode”

until the timer times out. If the ECM is used as a test

ECM for more than one engine, the “Test ECM Mode”

must be reactivated. Anytime prior to the “Test ECM

Mode” timing out, the ECM can be reset to 24 hours.

Note: If a newer software version is available for the

engine, install the newest software on the suspect

ECM. If the new software does not eliminate the fault,

continue with this procedure.

2.  Use the “Copy Configuration” feature on  the

electronic service tool to copy the  parameters

from the suspect ECM.

i03898736

Factory Passwords

Note: If the “ECM Replacement”  feature cannot

be used, record the programmed values  into the

“Customer Specified Parameters Worksheet”. Also

record the system configuration parameters.

NOTICE

3.  Disconnect the suspect ECM. Temporarily connect

the test ECM to the engine. Do not mount the test

ECM on the engine.

Operating the engine with a flash file not designed for

that engine will damage the engine. Be sure the flash

file is correct for your engine.

4.  Flash program the test ECM with the  newest

software that is available.

Note: Factory passwords are  provided only to

Perkins authorized distributors.

5.  Start the “Test ECM Mode” on  the electronic

service tool. Access the  feature through the

“Service” menu. The electronic service tool will

display the status of the test ECM and the hours

that are remaining for the “Test ECM Mode”.

Factory passwords are required to perform each of

the following functions:

This document is printed from SPI². Not for RESALE

KENR9116-01

Troubleshooting Section

•  Program a new Electronic  Control Module

(ECM).

Note: You must have the engine serial number  in

order to search for the part number of the flash file.

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.

2.  Connect the electronic service  tool to the

diagnostic connector.

3.  Turn the keyswitch to the ON position. Do not start

the engine.

4.  Select “WinFlash” from the “Utilities” menu on the

•  Rerate the engine.

electronic service tool.

Rerating may require changing the interlock code,

which is protected by factory passwords.

Note: If WinFlash will not  communicate with the

ECM, refer to Troubleshooting, “Electronic Service

Tool Will Not Communicate with ECM”.

•  Unlock parameters.

5.  Flash program the flash file into the ECM.

Factory passwords are  required in order to

unlock certain system configuration parameters.

Refer to Troubleshooting, “System Configuration

Parameters”.

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.

•  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 the

fault has been corrected. For example, the 190-15

Engine Overspeed requires the use  of factory

passwords in order to clear the code from  ECM

memory.

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.

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. The electronic service tool will display the

information that is required to obtain the passwords.

f.  The electronic service  tool will indicate when

the flash programming has been successfully

completed.

6.  Use the electronic service tool  to check for

diagnostic code 631-2. If this diagnostic code is

active and the flash file is not being installed  in

order to change the engine rating,  repeat this

procedure from 1. If this diagnostic code is active

and the flash file is  being installed in order to

change the engine rating, factory passwords must

be obtained.

Flash Programming

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.

Flash Programming  – A method of loading a flash

file into the Electronic Control Module (ECM)

The electronic service tool is utilized to flash program

a flash file into the ECM.  The flash programming

transfers the flash file from the PC to the ECM.

8.  Start the engine and check for proper operation.

Check that there are no active diagnostic codes.

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 web site.

Injector Code - Calibrate

Illustration 27

Sequence for recording the injector code

The electronic service tool is used to load the injector

codes into the ECM.

Injector codes are codes that are 30 hexadecimal

characters in length that are  supplied with each

injector. The code is on  a plate on the top of the

injector and a card is also included in the packaging

for the injector. The code is used by the Electronic

Control Module (ECM) to balance the performance

of the injectors.

The injector codes must be loaded into the ECM if

any of the following conditions occur:

•  An electronic unit injector is replaced.

•  The ECM is replaced.

•  Diagnostic code 268-2 is active.

•  Electronic unit injectors are exchanged between

cylinders.

Note: Diagnostic code 268-2 will also become active

if the engine serial number,  FLS or FTS are not

entered into the ECM.

If the ECM is  replaced, the injector codes are

normally transferred to the new  ECM as part of

the “Copy Configuration” procedure. If the  “Copy

Configuration” procedure fails, the injector codes

must be loaded manually.

Installing Injector Codes

Note: The injector code is located on the electronic

unit injector.

8.  Click on the “OK” button.

The injector code is loaded into the ECM.

The number of these non-programmable parameters

that are visible  depends on the value  that is

programmed into the “Number of  Switch Inputs”

parameter. “Open” signifies that the switch is in the

OFF position. “Ground” signifies that the switch is

in the ON position.

9.  Repeat the procedure for each  cylinder, as

required.

Exchanging Electronic Unit Injectors

Exchanging electronic unit  injectors can help

determine if a combustion problem is in the electronic

unit injector or in the cylinder. If two electronic unit

injectors that are currently installed in the engine are

exchanged between cylinders, the injector codes

must also be exchanged. Press  the “Exchange”

button at the bottom of the “Injector Trim Calibration”

screen on the electronic service tool. Select the two

electronic unit injectors that will be exchanged and

press the “OK” button. The tattletale for the electronic

unit injectors that were exchanged will increase by

one.
