Can I Do a Car Diagnostic Myself?

Published by

Yes, you can perform basic car diagnostics yourself using an OBD-II scanner. These devices plug into your car's diagnostic port, usually located under the dashboard, and read trouble codes stored in the computer. Basic scanners cost $20-50 and display codes you can research with our OBD-II code lookup tool. You can also use your phone as a diagnostic tool with a Bluetooth adapter. While DIY diagnostics work well for common issues, some problems require professional equipment. Complex electrical issues, transmission problems, and manufacturer-specific codes often need dealer-level scanners. Compare costs: full diagnostic pricing.
