1996 Lexus SC 400FACTORY OEM SERVICE PROCEDURE

System Operation Check

Turn ignition on. AIR BAG warning light should come on for about 7 seconds and then go off, indicating SRS is okay. If AIR BAG warning light does not come on, service Supplemental Restraint System (SRS). If AIR BAG warning light stays on constantly, service SRS. If AIR BAG warning light comes on for about 7 seconds, goes off, then starts flashing, a fault code is set in memory. Repair as necessary.

NOTE: On seat belt pre-tensioner equipped vehicles, the seat belt warning light should also come on for about 7 seconds and then go off (with seat belt fastened).
