What is Navistar Diamond Logic Builder?

The International® Diamond LogicBuilder software provides the ability to program, diagnose and simulate  features in the Electrical System Controller (ESC) module on the Industry’s First High Performance Trucks®.

The Diamond LogicBuilder program allows users to configure switches, the gauge cluster, and the parameters that are programmed in the ESC. The Advanced Logic capability in DLB is covered in a separate manual. Advanced Logic provides the ability to write custom features beyond what is offered by the advertised feature codes. It is not usually offered at the Dealer Level and is primarily intended to be used by Body Builders. Dealers do have the ability to view Advanced Logic when it has been installed on a vehicle.
