Modern cars have the capacity of a few computers, are tooled with software that contains millions of lines of programming code and produce gigabytes of data, but they are still different from connected cars.
An intelligent vehicle is able to optimize its performance to reduce fuel consumption, show the best path based on current road and weather conditions, detect engine errors, and gather information data to negotiate lower insurance rates.
Most cars and light trucks are equipped with onboard diagnostics or an OBD II port, which provides access to data from the engine control unit (ECU). An external device must be connected to obtain the information.
The OBD-II specifications provide a standardized hardware interface – a socket 16-pin (2×8) J1962 connector, so a single external device can be used for most vehicle models. It must also have an internet connection to transmit the collected data. To process all the information collected from the OBD2 device, you still need an on-board vehicle diagnostic application.
Such a tool is ideal for industries such as cab and limousine services, general transportation, and hazardous goods transport. With a vehicle monitoring app that can be customized to meet the needs of your organization and customers, you can make sure your drivers are following best practices.
Let’s take a look at the pros and cons of 7 automotive diagnostic apps to keep your car performing, which we believe to be the market leader at the moment.
THE MOST POPULAR OBD DIAGNOSTIC APPS FOR ANDROID 2021
