• Read and Clear Error Codes: View and clear diagnostic trouble codes (DTCs) stored in your car’s computer.
• Monitor Live Data: Access real-time information from various sensors, such as engine speed, coolant temperature, and oxygen sensor readings.
• Assess Vehicle Health: Get a better understanding of your car’s overall health and identify potential problems before they become major headaches.
