Mercedes HHT-WIN - Classic Diagnostic & Programming Tool

Full Diagnostics, ECU Programming & Key Functions for Pre-2001 Mercedes Vehicles

HHT-WIN (Hand-Held Tester for Windows) is the original Mercedes-Benz dealer software used for servicing pre-CAN systems — covering 1980s to early 2000s models. This tool offers more than just diagnostics: it delivers full offline access to ECU programming, variant coding, and key adaptation, making it a must-have for any workshop working with classic Benz platforms.

Seamlessly integrated into the DAS environment, HHT-WIN runs offline and communicates with older K-line-based control units that modern systems no longer support.

Key Features

• ✅ Offline ECU programming and variant coding on supported modules
• ✅ Key adaptation and immobilizer pairing for older DAS/EIS systems
• ✅ Full system diagnostics: engine, ABS, SRS, transmission, climate, IC, and more
• ✅ View and log live sensor data from legacy modules
• ✅ Execute actuator tests and system resets
• ✅ Control unit identification, coding, and personalization

📌 Ideal for workshops maintaining legacy Mercedes models with programming needs no longer supported by newer platforms.
