Replacing the ECM
NOTICE
Care must be taken to ensure that fl uids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fl uid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing fl uids.
Dispose of all fl uids according to local regulations and
mandates.
NOTICE
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 fl ash fi le 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.
Use the Electronic Service Tool to read the
parameters in the suspect ECM. Record the
parameters in the suspect ECM. Install the fl ash fi le
into the new ECM. After the ECM is installed on the
engine, the parameters must be programmed into
the new ECM.
Note: When a new ECM is not available, you may
need to remove an ECM from an engine that is not in
service. The ECM must have the same serial number
suf fi x. Ensure that the replacement ECM and the
fl ash fi le match the suspect ECM. Be sure to record
the parameters from the replacement ECM. Use the
“Copy Con fi guration ECM Replacement” function in
the Electronic Service Tool.
NOTICE
If the fl ash fi le 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 Con fi guration ECM Replacement”
function from the Electronic Service Tool. If the
“Copy Con fi guration” is successful, proceed to
Step 4. If the “Copy Con fi guration” 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
“Con fi guration” screen.
•
Record all of the parameters on the “Throttle
Con fi guration” screen.
• Record all of the parameters on the “Mode
Con fi guration” 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 Perkins Secured Internet.
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. Download the fl ash fi le.
a. Connect the Electronic Service Tool to the
diagnostic connector.
b. Select “WinFlash” from the “Utilities” menu of
the electronic service tool.
c. Select the downloaded fl ash fi le.
