Buying advice

When choosing a diagnostic tool, consider your skill level and needs: basic code readers suffice for check engine lights, while advanced DIYers benefit from bi-directional or all-system scanners. Ensure compatibility with your vehicle's OBD2 protocol and check for software update costs. Prices range from $20 to over $700; avoid the cheapest if you need live data or ABS/SRS support.
