The Central Configuration (CC) or "As-Built" data dictates the feature set activated on the vehicle. DET permits direct editing of these binaries.
If you are a professional technician looking to perform module-level repairs (cloning ECUs, enabling OEM hidden features, recovering dead modules), invest the time to read the manual cover to cover. It is dry. It is technical. But it turns a confusing hex editor into the most powerful diagnostic tool Ford has ever released.
Ford vehicles rely on "As-Built" data—hexadecimal code strings that control everything from door lock behavior to transmission shift points. The engineering manual teaches you how to read, modify, and restore this data using the tool’s advanced features. Ford Diagnostic Engineering Tool Manual
Let’s walk through a common repair to demonstrate how the manual functions.
| Section | Function | |---------|----------| | Dashboard | Active vehicle session, voltage, VIN, sync status | | Network Scan | Detects all ECUs, identifies missing/unauthorized modules | | Advanced Diagnostics | Direct routine control, DTC analysis with engineering data | | Module Programming | Bootloader flash, configuration data blocks | | Oscilloscope Mode | Signal capture on LIN, SENT, and HS-CAN | | Engineering Console | Raw UDS requests, security access (0x27) | The Central Configuration (CC) or "As-Built" data dictates
While the is the official dealer-level software for diagnostics and module programming, the Diagnostic Engineering Tool (DET) is designed for engineers and advanced users who need to perform tasks not typically required (or allowed) in a standard service bay, such as accessing a module's raw configuration data or debugging custom software. The Ford Diagnostic and Repair System (FDRS) is the newer cloud-based platform that is gradually replacing IDS for many tasks.

IDS is Ford's legacy diagnostic platform, designed as a comprehensive dealer-level tool providing full diagnostic coverage for most Ford, Lincoln, and Mercury vehicles manufactured between 1996 and 2018.
