What Features Should I Look for in a Diagnostic Scan Tool?

When selecting a diagnostic scan tool, consider these key features:

• Compatibility: Make sure the tool is compatible with the vehicles you plan to diagnose.
• Functions: Look for key functions like reading and clearing error codes, performing relearns, and running system tests. Verify that the tool offers the functions you need.
• Updates: Check the update policy, such as how long free updates are offered. Decide whether you prefer a tool with lifetime free updates or one that includes 1-2 years of free updates. Also, look into the cost for annual updates.
