Summary Highlights

• ECU connection workflow for service diagnostics and inspection
• Read ECU information and identify supported systems
• Fault diagnosis (DTCs): view current and stored faults
• Measurement values / live data viewing for troubleshooting
• Diagnostic tests for checking inputs/outputs (where supported)
• Data logging / saved sessions for later comparison and analysis
• Service settings and adjustment pages (model dependent)

Package contents

• YANMAR DIAGNOSTIC TOOL SA-DIRECT 2.37.0.exe
• 1 SETUP (folder)
• 2 REPLACE (folder)
• 3 FIREWALL (folder)

Compatibility notes

• Coverage depends on the specific Yanmar model, ECU generation, and the supported connection method used in your workshop.
• Some functions may appear or stay hidden depending on the detected ECU and product family.
• If your build includes optional online-related functions, availability depends on access and environment.

Basic usage (quick start)

• Launch SA-Direct and choose the product category (Industrial Engine / Agriculture / Marine/Ocean / Energy System / Construction).
• Connect to the ECU using the supported workshop connection method for your machine.
• Open fault diagnosis to read DTCs, then review measurement values and run available tests if needed.
• Use logging/saved sessions when you need before/after comparisons (repairs, adjustments, intermittent faults).

Operating systems

• Windows PC (x64) (packaged as a Windows executable)

Minimum system requirements

• CPU: Dual-core or better
• RAM: 4 GB (8 GB recommended)
• Storage: 2 GB free space (more if logs/sessions are stored locally)
