The VehicleMRI database consists of thousands of test and data parameters. All tests are not supported by all vehicles and are dependent upon the vehicle being tested. Once the desired inspection test and vehicle to be inspected are known, VehicleMRI will automatically select the correct items to test for you. Here is a sampling of some of the systems and data items that VehicleMRI will collect and analyze.
