Troubleshooting Section

Replacing the ECM

Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing fluids.
Dispose of all fluids according to local regulations and
mandates.
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
The engine is equipped with an Electronic Control
Module (ECM). The ECM contains no moving parts.
Follow the troubleshooting procedures in this manual
in order to be sure that replacing the ECM will correct
the problem. Verify that the suspect ECM is the
cause of the problem.
Note: Ensure that the ECM is receiving power
and that the ECM is properly grounded before
replacement of the ECM is attempted. Refer to the
schematic diagram.
A test ECM can be used in order to determine if the
ECM on the engine is faulty. Install a test ECM in
place of the suspect ECM. Install the flash file with
the correct part number into the test ECM. Program
the parameters for the test ECM. The parameters
must match the parameters in the suspect ECM.
Refer to the following test steps for details. If the test
ECM resolves the problem, reconnect the suspect
ECM. Verify that the problem returns. If the problem
returns, replace the ECM.
Note: If an ECM is intended to be used as a test
ECM, "Test ECM Mode" must be selected on the
electronic service tool before the engine serial
number is entered.
Use the electronic service tool to read the parameters
in the suspect ECM. Record the parameters in
the suspect ECM. Install the flash file into the new
ECM. After the ECM is installed on the engine, the
parameters must be programmed into the new ECM.

NOTICE
NOTICE
Note: When a new ECM is not available, an ECM
can be used from an engine that is not in service.
The ECM must have the same serial number
suffix. Ensure that the replacement ECM and the
part number for the flash file match the suspect
ECM. Be sure to record the parameters from the
replacement ECM. Use the "Copy Configuration ECM
Replacement" function in the electronic service tool.
NOTICE
If the flash file and engine application are not matched,
engine damage may result.
Perform the following procedure in order to replace
the ECM.
1. Connect the electronic service tool to the
diagnostic connector.
2. Use the "Copy Configuration ECM Replacement"
function from the electronic service tool. If the
"Copy Configuration" is successful, proceed to
Step 4. If the "Copy Configuration" failed, proceed
to Step 3.
Note: Record any Logged Faults and Events for your
records.
3. Record the following parameters:
•
Record all of the parameters on the
"Configuration" screen.
•
Record all of the parameters on the "Throttle
Configuration" screen.
•
Record all of the parameters on the "Mode
Configuration" screen.
•
Record the serial numbers of the electronic unit
injectors. The injector serial numbers are shown
on the "Injector Trim Calibration" screen.
Note: If the parameters cannot be read, the
parameters must be obtained elsewhere. Some
parameters are stamped on the engine information
plate, but most parameters must be obtained from
the PTMI data on the Perkins intranet.
4. Remove power from the ECM.
5. Remove the ECM. Refer to Disassembly and
Assembly, "Electronic Control Module - Remove
and Install".
6. Install the replacement ECM. Refer to Disassembly
and Assembly, "Electronic Control Module -
Remove and Install".
7. If the replacement ECM is intended to be used
as a test ECM, select "Test ECM Mode" on the
electronic service tool.
