Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

This tool is designed to compare Diamond Logic feature data across multiple vehicle configuration files. It allows users to quickly load files either manually or directly from the Diamond Logic Builder Vehicles folder using VIN-based selection. As files are added or removed, the comparison runs automatically with no manual action required. The program presents results in an interactive table that shows feature codes, descriptions, access levels, and whether each feature is present in each selected file. Built-in search, filtering, and sorting make it easy to locate specific features or focus only on differences between files. Column visibility can be customized to show or hide descriptions and access information as needed. Users can remove files individually or clear all files at once, with results updating instantly. The tool also includes reporting and export options that reflect exactly what is visible on screen, allowing results to be printed, copied, saved as text, or exported to CSV for use in Excel or other spreadsheet tools. Overall, the program streamlines the process of comparing vehicle feature configurations, helping users quickly identify differences, validate setups, and document results without manual comparison or external tools.

In some geographic areas, ambient temperatures reaching below 15°F (-10 °C), including high levels of humidity, an operator may experience engine stalling, low performance, and or poor aftertreatment performance. This is caused by condensation accumulating and freezing within the Charge Air Cooler (CAC); affecting air flow into the engine. This article lists all the currently available winter front covers that can be installed on the front grille and bumper to reduce cold air flow to the engine compartment.
