International Diamond Logic Builder 2024 description of the catalogue:

DIAMOND LOGIC BUILDER FLEET SOFTWARE

In 2001 International Truck and Engine introduced the Industry’s First High Performance Trucks®. With this introduction, a very innovative and flexible electrical system employing multiplexing technology was introduced. The system is standard on all high performance trucks. In addition, many options can be ordered and/or added to the vehicle by the dealer.

The initial release of The Industry’s First High Performance Truck® used the INTUNE® Fleet software program to diagnose electrical system problems.
As customers, dealers, body builders, suppliers and International engineers worked with this new multiplexed system, it was determined that a new software tool was necessary to fully utilize the many advantages and opportunities of the new vehicle electrical system.

The Diamond Logic® Builder Fleet software enhances diagnostic functions for the end user. This Diamond Logic® Builder Fleet User’s Manual describes the new software in detail and shows how to use it to maximize the efficiency and effectiveness of The Industry’s First High Performance Truck’s® electrical system integration.
