SYSTEM CONFIGURATION PARAMETERS
00053 00
System configuration parameters affect emissions, engine power, and machine applications. Default values for the
parameters are programmed at the factory. Some parameters (such as maximum engine rpm and user defined shutdown) may
be changed to suit the needs of the specific application. Other parameters such as Full Load Setting (FLS) or Full Torque Set-
ting (FTS) should not be changed unless the engine is rerated or a new ECM is installed. FLS and FTS are stamped on the
engine information ratings plate located on the engine (TM 5-3805-290-10). These parameters are protected from unautho-
rized change by passwords.
View and/or change parameters using the Configuration Tool on the toolbar, or by selecting "Configuration" from the
"Service" menu in ET. The Configuration display area in ET has four columns: Description, Value, Unit, and TT. The Descrip-
tion column gives the name of the parameter. The Unit column displays the configuration parameter units. The TT column dis-
plays the list of the total tattletales, which represent the number of times the configuration parameter value has changed.
The push-buttons in the Configuration screen are "Change" or "Print". The "Change" push-buttons allow you to change
the configuration values. This is only enabled if the parameter's configuration can be changed. Parameters that cannot be
changed have a yellow key symbol on the left. The ECM Replacement function in ET copies the relevant configuration param-
eters from one ECM to the other. Table 1 lists the system configuration parameters, data range, default value, and unit for the
924G Wheel Loader.

(2)
Copy configuration of the existing ECM to the MSD. Refer to Copy Configuration from ECM in this work
package.
(3)
Remove the ECM. Refer to Remove ECM in this work package.
(4)
Install the new ECM. Refer to Install ECM in this work package.
(5)
Flash program ECM. Refer to Flash Programming in this work package.
(6)
Copy the configuration of the old ECM to the new ECM. Refer to Copy Configuration (Program ECM) in
