Reset the “check engine” light: Once you’ve addressed the issue, use the scanner to clear the codes and turn off the warning light.
Monitor live data: Get real-time insights into various engine parameters like speed, temperature, and oxygen sensor readings.
Perform advanced diagnostics: Some scanners offer more advanced features for in-depth analysis of specific systems like ABS, airbags, and transmission.
