The shorting bar prevents current from traveling through the pretensioner during servicing. The shorting bar disengaged when the connecotr is connected. The pretensioner is an electronically controlled pyrotechnical reactor which reduce seat belt slack when it is actived with air bags. The front seat belt pretensioner must be replaced after an accident that cause its activation.
