1. A method for monitoring a controller of a vehicle, the method comprising:

  • detecting occurrence of a fault associated with operation of the controller in the vehicle;

    determining configuration information associated with the vehicle;

    determining vehicle operating states, wherein the vehicle operating states include software execution states including a software mode change, a module triggering event including a power-on or a power-off event, and a function request;

    correlating, via a second controller, the fault with the vehicle operating states and the configuration information associated with the vehicle;

    isolating, via the second controller, the fault to one of a hardware fault or a software fault associated with the controller based upon the correlation and the configuration information associated with the vehicle; and

    generating, via the second controller, an output indicating the fault that is isolated to one of the hardware fault or the software fault;

    wherein the second controller is disposed off-vehicle.
