Vgate iCar Pro diagnostic adapter with diagnostic and error removal function. The adapter connects to the OBD2 diagnostic port and works with applications such as Bimmercode, Torque Pro, JScan and others. Once connected, you will be able to read error codes via a smartphone app and determine what a particular indicator on the dashboard means without having to go to a car service. In real time you can view engine speed, engine speed, coolant temperature, fuel consumption, turbine pressure and about 500 other values. And the adapter can be left on, as it saves battery charge and does not discharge it when idle. After stopping the engine for half an hour, the device goes into sleep mode, and after the startup it turns on again.
