TROUBLE SHOOTING APPARATUS AND METHOD FOR BIO-SIGNAL SENSOR EQUIPPED IN VEHICLE

A fault diagnosis method for a bio-signal sensor for the vehicle includes measuring a first bio-signal through the bio-signal sensor in response to a seating detecting signal, measuring a second bio-signal through the bio-signal sensor in response to input through an on-board interface, and determining whether the bio-signal sensor may have malfunctioned according to whether the second bio-signal includes a signal deviating from a range set in response to the first bio-signal.
