Roush Industries, a leader in automotive engineering and performance innovation, partnered with Symphonize to enhance and modernize RDT 2.0 — a powerful desktop-based diagnostic application used to diagnose vehicles and deploy PCM calibration updates.

Supporting in-plant manufacturing, aftermarket service technicians, and end-consumers required a scalable, secure, and transparent diagnostic platform capable of operating across connected and offline environments.

To meet these demands, Roush collaborated with Symphonize to redesign and rebuild RDT 2.0 — transforming it from a legacy diagnostic tool into a connected, enterprise-grade vehicle service ecosystem.

Our Solution: A Connected, Scalable Diagnostic Platform

Symphonize engineered RDT 2.0 as a hybrid platform — combining local desktop workflows with scalable AWS-backed infrastructure to support manufacturing-grade reliability and end-user flexibility.

Modernized Technician Interface: Redesigned the desktop-based diagnostic workflow to introduce structured testing steps (Preconditions → Key On → Run Test → Results), improving clarity, reducing technician friction, and enhancing DTC visualization.

Real-Time Diagnostic & Logging Layer: Implemented enhanced DTC display modules, structured result views, persistent logging, and downloadable system logs to support audit trails and traceability.

Transparent System Status & Connectivity Monitoring: Developed integrated status panels to display cloud connectivity, device detection, vehicle connection state, and software version validation — reducing operational ambiguity during diagnostics.

Cloud-Integrated Infrastructure: Built scalable web services, ETL workflows, and AWS-hosted backend systems to support calibration distribution, batch processing, and enterprise scalability while maintaining offline compatibility for manufacturing facilities.

Multi-Environment Workflow Support: Engineered adaptable client-side workflows to support in-plant manufacturing, aftermarket service technicians, and at-home end-consumer usage scenarios.

Enterprise Governance & Administrative Controls: Developed VIN-based lookup tools, calibration version control, release state management (Draft / Released / Deprecated), installer portal overrides, and role-based access permissions.

Structured Diagnostic Execution

The guided workflow (Preconditions → Key On → Run Test → Results) introduces clarity into complex service procedures, reducing technician confusion and ensuring accurate diagnostic sequencing.

Real-Time Code Visibility & Action Feedback

Enhanced DTC display screens and confirmation states provide immediate operational feedback, clearer code grouping, and structured exit/confirm actions—improving accuracy during testing and calibration.

Transparent System & Vehicle Connectivity

Integrated status panels clearly display cloud connection, device detection, vehicle communication, and software validation—reducing uncertainty and increasing technician trust during live operations.

Reduced Cognitive Load Through UX Redesign

Refined action zones, structured messaging, and simplified visual hierarchy ensure technicians always understand system state, required actions, and next steps—even during long-running operations.

Enterprise-Level Calibration Governance

VIN lookup tools, version control states (Draft / Released / Deprecated), installer portal overrides, and administrative dashboards enable centralized control of calibration programs across multiple vehicle platforms.

Impact: Enabling Enterprise-Grade Vehicle Diagnostics

The enhanced RDT 2.0 platform has streamlined diagnostic operations, strengthened calibration governance, and improved technician clarity across environments. By combining modern UX design with scalable cloud integration, the system supports manufacturing efficiency, aftermarket service performance, and long-term vehicle program scalability.

Through this modernization, Roush reinforced its position as a leader in automotive diagnostics, calibration technology, and engineering innovation.
