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.
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 10b.
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
PTMI data.
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 used as a test ECM,
select “Test ECM Mode” on the electronic service
tool.
8. Download the flash file.
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 flash file.
9. If necessary, use the electronic service tool to clear
the rating interlock. To clear the rating interlock,
enter the factory password when the electronic
service tool is first connected. Activating the Test
ECM mode will also clear the rating interlock.
10. Use the electronic service tool to program the
parameters. Perform the following procedure.
a. If the “Copy Configuration” procedure was
successful, use the “Copy Configuration, ECM
Replacement” function to load the configuration
file into the ECM.
Note: During the following procedure, factory
passwords may be required.
b. If the “Copy Configuration” procedure failed,
configure the parameters individually. The
parameters should match the parameters from
step 3.
11. Perform the “High Pressure Fuel Pump
Calibration” .
12. Check for logged diagnostic codes. Factory
passwords are required to clear logged events.

Electrical Connectors - Inspect
Most electrical faults are caused by poor
connections. The following procedure will help in
detecting faults with connectors and with wiring. If a
fault is found, correct the condition and verify that the
fault is resolved.
