No, TDK bumpers do not affect airbag functionality. Sensors are located either in the front of the vehicle, in the passenger area, or in the engine compartment. Different types of sensors measure wheel speed, seat occupancy, brake pressure, and impact. Other vehicle status indicators are also monitored by the airbag control unit, which analyzes the data and can relay safety features like seat belt lock and auto door locks in addition to airbag deployment.
