Basic Features

Read and Clear the trouble codes – The adapter is plugged into an OBD2 port, and then it gets access to a vehicle’s computer. When you have Check Engine Light, the computer stores the trouble code which helps you diagnose the engine problem. You can read the codes on your Android devices or Windows PC. After fixing the problem, you can clear the codes to turn off Check Engine Light.

Before the computer triggers Check Engine Light on and sets a trouble code as a permanent code, the computer has already had the code as a pending code. You can read and clear both permanent and pending codes.

Freeze Frame data – It’s a snapshot of engine data at the moment the computer stores a trouble code. It gives a rough idea of vehicle’s condition at that moment and helps you where to start diagnosing first.

I/M Readiness Monitors – The computer performs a self-test on numbers of systems every after being reset (cleared Check Engine Light.) It takes a while and a couple of drive cycles to complete. If they are not finished, it’s not ready to take a car to the state inspection. Regulation of inspection varies from the state to the state. It may pass the inspection even when some systems’ self-tests are not finished.

Live Data – Both OBDLink Android app and OBDwiz can display various engine data such as RPM, Coolant temp, Mass Air Flow volume, etc in a graph, dial, or digital style.
