A diagnostic system for a vehicle comprises a diagnostic module, a control module, and a hardware interface module. The diagnostic module selectively diagnoses a fault in one or more of components that are integrated within a housing. The control module receives a request for testing of the diagnostic module and retrieves predetermined fault data corresponding to the fault. The hardware interface module receives component data for the diagnosis and the predetermined fault data, disables provision of the component data to the diagnostic module, and provides the predetermined fault data to the diagnostic module for the diagnosis.
