Patent abstract

Disclosed is a calibration apparatus for an airbag inflator resistance. The calibration apparatus for an airbag inflator resistance includes: an airbag inflator unit for applying a deployment signal for deployment of an airbag; a resistance detection unit for detecting a change in the resistance of the airbag inflator connector; and a control unit for self-cleaning the airbag inflator connector in accordance with the resultant resistance detected by the resistance detection unit. The calibration apparatus is effective in preventing malfunction of an airbag warning light and ensuring reliability by preventing an increase in resistance due to the contamination of the airbag inflator by the self-diagnosing and self-cleaning effect using an electric current.
