A diagnostic process includes analyzing vehicle data received from a vehicle to identify diagnostic data, and to determine an identity of the vehicle. A most likely fix is determined based on a combined assessment of the diagnostic data and the vehicle identity. A determination of a special function test to run on the vehicle is made based on the determined most likely fix. A signal is generated to run the special function test, and a determination of a pass or fail status is made based on the special function test. If no special function test is associated with the most likely fix, more targeted testing can be implemented through the use of a test box configured to monitor communications along communication pathways on the vehicle, and also to selectively activate/deactivate components on the vehicle.
