This downloadable diagnostic manual provides factory troubleshooting procedures for 2004-2006 International DT466, DT570, and HT570 diesel engines. Designed for diesel technicians, fleet maintenance personnel, and independent repair shops, it focuses on symptom-based diagnostics and electronic control system troubleshooting to help identify and resolve engine performance issues quickly and accurately.

Unlike a repair manual, this publication is dedicated to diagnosing faults and determining the root cause of engine and ECM-related problems. Detailed procedures guide you through engine symptom diagnostics, electronic control system testing, diagnostic trouble codes (DTCs), and the use of International’s Electronic Service Tool (EST).

The manual covers a wide range of common engine concerns, including hard starting, no-start conditions, rough idle, low power, excessive fuel consumption, smoke, low oil pressure, overheating, fuel system issues, coolant contamination, and intermittent engine performance problems. Step-by-step diagnostic tests help technicians pinpoint failures before replacing parts unnecessarily.

Additional sections explain engine systems, vehicle features, diagnostic software operation, cruise switch diagnostics, performance specifications, and the proper use of diagnostic tools and accessories. A complete DTC reference is included to assist with electronic fault diagnosis and repair.

For ease of use, the PDF features clickable table of contents links, allowing you to quickly navigate to the desired section on your computer, tablet, or smartphone. The manual is fully searchable and can be printed as needed for shop use.
