Newer model vehicles run off a central computer system that tells the different aspects of the engine system what to do and when. The computer operates through smaller modules and machines within the car to relay the necessary information. In the case of an injector driver module, when a driver starts the car and presses the gas pedal, the main computer system sends a signal to the injector drive module dictating the amount and timing of fuel. The module then sends that information to the fuel injection system. Diesel engines commonly use power train control modules to operate the injector driver module. An engine that fails to crank can be a module problem.

Since the injector driver module runs off the main computer system, a mechanic can hook the vehicle up to a main repair computer to diagnose IDM failure.
