TopScan includes a one-touch I/M Readiness button for a quick smog status check and testing reports. The user can analyze a car's carbon emissions faster and more efficiently. It’s a great option for emission pre-tests on annual inspections and spot tests on the road.

TopScan’s vehicle performance tests take accurate measurements of vehicle acceleration, providing results at intervals defined by set speed and fixed distance measurements. Record accurate ⅛-mile, ¼-mile, and zero to 60 times whenever you need to, without a stopwatch.

How well is your engine running? The TopScan’s Volumetric Efficiency (VE) test helps measure airflow and power output just like the pros. Simply enter basic data, and the TopScan calculates your VE instantly, showing you exactly how well your engine is running.

Get more than just numbers, with data displayed the way you want it. TopScan turns raw data into easy-to-read charts and dashboards. Watch sensor values and parameters change in real time and compare up to four data streams side-by-side to spot performance issues instantly.

Turn every scan into a clear, professional report. TopScan logs system status, fault codes, and live data, then creates before-and-after comparisons to show exactly what’s been fixed. Perfect for sharing with customers or tracking your own repair history.

Spend less time inputting VIN numbers and tracking down missing digits with TopScan's AutoVIN and AutoScan functions. You'll work faster while AutoVIN automatically detects the vehicle’s make and model and AutoScan automatically pulls DTCs for review and repair.
