Official OEM Thermo King parts catalog entry for the Thermo King Tool YSAD Expert 2041969, verified by PEAK Thermo King and West Texas Thermo King Texas, Utah, Wyoming, Washington, Oregon, serving all of the USA.
Built for Performance: The Thermo King Tool YSAD Expert 2041969 equips certified technicians with an OEM-level diagnostic interface designed for Thermo King refrigeration systems. This diagnostic interface connects Yanmar engine ECUs to a PC running Yanmar SmartAssist Direct (YSAD) software, enabling fast fault code retrieval, live data access, and precise troubleshooting for temperature-controlled fleets.
Key Features & Customer Benefits
- YSAD Software Compatibility – Supports Yanmar SmartAssist Direct for full ECU diagnostics and configuration, improving service accuracy and reducing downtime.
- USB PC Connectivity – Connects a technician laptop directly to the Yanmar ECU for convenient, on-site data access without powering the entire unit.
- OEM-Grade Materials – Constructed for resistance to temperature and chemical exposure common in transport refrigeration environments for durable field use.
- CAN Bus & Signal Interface – Interfaces with keyswitch power, run signals, and CAN communications to analyze interactions between the Yanmar ECU and Thermo King base controller.
- Faster Diagnostics – Enables rapid fault isolation and operational data retrieval to support uptime and efficient fleet maintenance.
- Fleet ROI – Reduces diagnostic time and unnecessary part swaps, supporting lower service costs and improved asset availability for reefer trailers and refrigerated trucks.
