Monitor Real-time Data: Access live data streams from various sensors, such as engine RPM, coolant temperature, and oxygen sensor readings. This helps monitor vehicle performance and identify potential problems.
Perform Emissions Tests: Check your vehicle’s readiness for emissions testing.
And More: Depending on the scanner, you can perform advanced diagnostics, program keys, and access other vehicle-specific features.
