Disabling & Activating Air Bag System

NOTE: Saab vehicles are equipped with seat belt pretensioners. The SRS controls both air bags and seat belt pretensioners.

NOTE: The control module has 3 backup power sources. Two of them enable the front air bags to be activated for a minimum of 150 milliseconds after the regular power supply has failed and the third backup power source keeps the processor going for 150 milliseconds after the regular power supply has failed.

To disable SRS, disconnect and shield negative battery cable. To activate system, reconnect negative battery cable. Perform a system operation check. See SYSTEM OPERATION CHECK .
