System and method for demonstrating functionality of on-board diagnostics for vehicles

A system for demonstrating operation of on-board diagnostics in a vehicle having an internal combustion engine, the system comprising:

• at least one sensor for providing a signal corresponding to a current vehicle operating condition;
• at least one actuator for positioning a vehicle component;
• a control module in communication with the at least one sensor and at least one actuator, the control module modifying at least one control system parameter value associated with the at least one sensor and/or the at least one actuator in response to a request to demonstrate operation of the on-board diagnostics, and controlling the vehicle based on the modified value to imitate degraded performance of the at least one sensor and/or at least one actuator.

A computer readable storage medium having stored data including instructions executable by a computer to control a vehicle to demonstrate functionality of on-board diagnostics for the vehicle, the computer readable storage medium comprising:

• instructions for changing vehicle operation in response to a request to demonstrate functionality of the on-board diagnostics by changing at least one parameter value used to control the vehicle such that the vehicle operates similar to operation using a degraded component, the vehicle operation activating the on-board diagnostics to demonstrate functionality.
