Trip Record ACcess (TRAC)
Data Extraction System Software
TRAC is a PC-based software package that
extracts operational data stored in the Engine
Electronic Control Module (ECM). The extracted
data can be used to automate fleet record
keeping or analyzed to evaluate fleet performance
in key areas; such as, miles driven, fuel
consumed, engine hours, idle/PTO time, etc.
Fault codes and ECM set-up parameters can also
be reviewed to aid in troubleshooting, when
necessary.
TRAC is designed for use with all Detroit Diesel
engines that are equipped with the DDEC II and
new DDEC III ECM. In addition, it may be used to
extract stored data from other ECMs that are
SAE.TCM J1708 compatible. Once the data has
been extracted from the ECM, PC-based tools
such as spreadsheets or databases can be
utilized to organize the data for effective
management reporting and decision-making.
The TRAC system consists of: PC software and
manual, TRAC translator PC interface, data
extraction cable and
adapter.
Advanced Data Hub Analysis Software
The "Advanced Data Hub analysis software" is a
full-featured "smart system" that handles the
collection, analysis and reporting of operational
data generated by all versions of the Data Hub
system. The software is designed reduce the
user's time spent on data analysis. The powerful
analysis and reporting capabilities of the software
provide the user with an overview of the fleet

Data may also be presented in a greater level of
detail by utilizing the "Summary Reporting"
capability of the software. This allows the user to
review specific types of data, which are selected

Finally, the software provides a "User Interactive"
capability which allows the user to rapidly sort
through increasing levels of detail from the
computer keyboard. This feature is very useful in
investigating the occurrence of specific events.
Data generated by the Data Hub system may also
be easily exported to other applications for
additional processing, which allows users to
