Troubleshooting Section
Replacement of electronic components should
not be based on snapshot data alone.
If too much
emphasis is put on snapshot data, the result could
be a misdiagnosed root cause. Also when snapshot
data that is triggered by a diagnostic code is being
viewed, the ECM sets a sensor value with an active
diagnostic code to a default value when the code
is active. This is the reason that the sensor value
suddenly jumps to a speci
fi
c value at the trigger point
and the sensor value remains at the speci
fi
c value for
the rest of the snapshot frames.

Factory Passwords
NOTICE
Operating the engine with a
fl
ash
fi
le not designed for
that engine will damage the engine. Be sure the
fl
ash
fi
le is correct for your engine.
Note:
Factory passwords are provided only to
Perkins dealers.
Factory passwords are required to perform each of
the following functions:
•
Program a new Electronic Control Module (ECM).
When an ECM is replaced, the system
con
fi
guration 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.
•
Rerate the engine.
This may require changing the interlock code,
which is protected by factory passwords.
•
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
problem has been corrected. For example,
the E362-1 Engine Overspeed requires the
use of factory passwords in order to clear the
code from ECM memory.
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 and the electronic service
tool will display the information that is required
to obtain the passwords. For the worksheet that
is used for acquiring factory passwords, refer to
Troubleshooting, “Factory Passwords Worksheet”.

Flash Programming
Flash Programming –
A method of loading a
fl
ash
fi
le into the Electronic Control Module (ECM)
The electronic service tool can be utilized to
fl
ash program a
fl
ash
fi
le into the ECM. The
fl
ash
programming transfers the
fl
ash
fi
le from the PC to
the ECM.
Flash Programming a Flash File
1.
Obtain the part number for the new
fl
ash
fi
le.
Note:
If you do not have the part number for the
fl
ash
fi
le, use “PTMI” on the Perkins Internet.
Note:
You must have the engine serial number in
order to search for the
fl
ash
fi
le’s part number.
2.
Connect the electronic service tool to the service
tool connector.
3.
Turn the keyswitch to the ON position. Do not start
the engine.
4.
Select “WinFlash” from the “Utilities” menu on the
electronic service tool.
Note:
If “WinFlash” will not communicate with the
ECM, refer to Troubleshooting, “Electronic Service
Tool Will Not Communicate with ECM”.
5.
Flash program the
fl
ash
fi
le into the ECM.
a.
Select the engine ECM under the “Detected
ECMs”.
b.
Press the “Browse” button in order to select
the part number of the
fl
ash
fi
le that will be
programmed into the ECM.
c.
When the correct
fl
ash
fi
le is selected, press
the “Open” button.
