Troubleshooting Section
Note: When a test ECM is not available, you may
need to remove a
n ECM from an engine that is not in
service. The ECM must have the same serial number
suffix. Ensure that the replacement ECM and 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 Electron
ic 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 Con
figuration” 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
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
para
meters are stamped on the engine information
plate, but most parameters must be obtained from
the PTMI data on the Perkins Secured Internet.
4. Remove power from the ECM.
5. Rem
ove the ECM.
6. Install the replacement ECM.
7. Download the flash file.
a. Co
nnect the Electronic Service Tool to the
diagnostic connector.
b. Se
lect “WinFlash” from the “Utilities” menu of
the electronic service tool.
c
.
S
elect the downloaded flash file.
8. If necessary, use the electronic service tool to clear
theratinginte
rlock. 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.
9. 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
parameter
s should match the parameters from
step 3.
Perform t
he “Fuel System Verification Test”.
10. Check for logged diagnostic codes. Factory
password
s are required to clear Logged Events.

Self-Diagno s tics
The Electronic Control Module (ECM) has the ability
to detect faults in the electronic system and with
engine operation. When a fault is detected, a code is
generated. An alarm may also be generated. There
are two types of codes:
•
Diagnostic
•
Event
Diagnostic Code – Whenafaultintheelectronic
system is detected, the ECM generates a diagnostic
code. This indicates the specific fault in the circuitry.
Diagnostic codes can have two different states:
•
Active
•
Logged
Active Code – An active diagnostic code indicates
that an active fault has been detected by the control
system. Active codes require immediate attention.
Always service active codes prior to servicing logged
codes.
Logged Code – Every generated code is stored
in the permanent memory of the ECM. The codes
are logged for 100 operating hours unless a code is
cleared by use of the electronic service tool.
