System Configuration
Parameters
System configuration parameters affect the emissions
of the engine or the power of the engine. System
configuration parameters are programmed at the
factory. Normally, system configuration parameters
would never need to be changed through the life of
the engine. System configuration parameters must be
reprogrammed if an Electronic Control Module (ECM)
is replaced. System configuration parameters do not
need to be reprogrammed if the ECM software is
changed. Factory passwords are required to change
these parameters. The following information is a
description of the system configuration parameters.
Full Load Setting
The full load setting is a number that represents
the adjustment to the fuel system that was made
at the factory in order to fine tune the fuel system.
If the ECM is replaced, the full load setting must
be reprogrammed in order to prevent a 268-02
diagnostic code from becoming active.
Full Torque Setting
Full torque setting is similar to full load setting. If
the ECM is replaced, the full torque setting must
be reprogrammed in order to prevent a 268-02
diagnostic code from becoming active.
Rating Interlock
The rating interlock is a code that prevents the use of
an incorrect power rating and/or emission rating for
aspecific engine. Each horsepower rating and each
emission certification has a different code to all other
horsepower ratings and emission certifications.
When an ECM is replaced, this rating interlock code
must match the code that is stored in the ECM. If the
rating interlock code does not match the code that is
stored in the ECM, both of the following situations
will exist:
•
The engine will not run.
•
Diagnostic code 0253-02 Personality Module
mismatch will be active.
Note: The flash programming of a new rating
interlock replaces the old rating interlock.
This code does not need to be programmed when
the replacemen
t ECM is for the same engine rating.
If the ECM is for a different engine rating, then the
following com
ponents may need to be changed:
pistons, fuel injectors, and other components.
The engine information ratings plate must also be
changed in or
der to reflect the new rating.
Some systems such as the cooling system or the
transmissio
n may also require changes when the
engine is rerated. Please contact the local OEM
dealer for further information.
Engine Serial Number
When a new ECM is delivered, the engine serial
number in the ECM is not programmed. The engine
serial numbe
r should be programmed to match the
engine serial number that is stamped on the engine
information plate.
ECM Software Release Date
This parameter is defined by the rating interlock
and this parameter is not programmable. The ECM
software r
elease date is used to provide the version
of the software. The Customer parameters and the
software change levels can be monitored by this
date. The d

(NOV05). NOV is the month (November). 05 is the
year (2005).
