Abstract
A diagnostic system of a vehicle includes an energy absorber sandwiched between a front bumper fascia and a front bumper reinforcement of the vehicle. A sensing tube is located between a portion of the energy absorber and the front bumper reinforcement. A first pressure sensor and a second pressure sensor measure a first pressure of air and a second pressure of air within the sensing tube, respectively. An actuator is configured to actuate and vary a pressure within the sensing tube. A diagnostic module is configured to selectively diagnose the presence of a fault with the sensing tube based on at least one of: a first change in the first pressure in response to actuation of the actuator; and a second change in the second pressure in response to the actuation of the actuator.
