  • Pass Emissions Tests with Ease & Gain Live Engine Insights: Drive to your smog test with confidence. The I/M Readiness mode on this obd scanner​ instantly shows if your car will pass. Avoid costly re-tests. Go beyond codes with real-time Live Data​ to monitor sensor health, spot trends, and use Freeze Frame to see the exact conditions when a fault occurred. It's like having a mechanic's insight on your dashboard.
  • Professional Accuracy for DIYers and Home Mechanics: Enjoy professional-level accuracy without the price tag. The T400 intelligent chip ensures 99.8% accurate battery diagnostics.
