The on-board diagnostic (OBD) system for the supplemental restraint system module (SRS) continually diagnoses the function of supplemental restraint system components and stores any diagnostic trouble codes (DTCs). The diagnostic trouble codes (DTCs) can then be read off via VIDA (Volvo scan tool). The principle behind VIDA information presentation is the same as for other on-board diagnostic (OBD) systems.
