SYSTEM OUTLINE
THE SRS IS A DRIVER AND PASSENGER PROTECTION DEVICE WHICH HAS A SUPPLEMENTAL ROLE TO THE SEAT
BELTS.
WHEN THE IGNITION SW IS TURNED TO ACC OR ON, THE CURRENT FROM THE CIG FUSE FLOWS TO TERMINAL 16
OF THE AIRBAG SENSOR ASSEMBLY. ONLY WHEN THE IGNITION SW IS ON DOES THE CURRENT FROM THE IGN
FUSE FLOW TO TERMINAL 15 OF THE AIRBAG SENSOR ASSEMBLY.
IF AN ACCIDENT OCCURS WHILE DRIVING, DECELERATION CAUSED BY A FRONTAL IMPACT IS DETECTED BY THE
SENSOR IN THE AIRBAG SENSOR ASSEMBLY, AND WHEN THE FRONTAL IMPACT EXCEEDS A SET LEVEL (WHEN
THE SAFING SENSOR BUILT INTO THE AIRBAG SENSOR ASSEMBLY IS ON, THE FLOOR SENSOR BUILT INTO THE
AIRBAG SENSOR ASSEMBLY IS ON AND THE AIRBAG SENSOR ASSEMBLY IS ON), THE CURRENT FROM THE CIG OR
THE IGN FUSE FLOWS THROUGH THE AIRBAG SENSOR ASSEMBLY TO TERMINALS 7 AND 3 OF THE AIRBAG
SENSOR ASSEMBLY TO TERMINAL 1 OF THE AIRBAG SQUIB → TERMINAL 2 → TERMINALS 6 AND 2 OF THE
AIRBAG SENSOR ASSEMBLY → THE FLOOR SENSOR BUILT INTO THE AIRBAG SENSOR ASSEMBLY → TERMINAL 9,
TERMINAL 10 OR BODY GROUND → GROUND. WHEN THE SAFING SENSOR BUILT INTO THE AIRBAG SENSOR
ASSEMBLY IS ON, AND FLOOR SENSOR BUILT INTO THE AIRBAG SENSOR ASSEMBLY IS ON, ONE OF THE
ABOVE-MENTIONED CIRCUITS IS ACTIVATED SO THAT THE CURRENT FLOWS TO THE AIRBAG SQUIBS, CAUSING
IT TO OPERATE.
THE AIRBAG STORED INSIDE THE STEERING WHEEL PAD IS INSTANTANEOUSLY EXPANDED TO SOFTEN THE
SHOCK TO A DRIVER.
SIMULTANEOUSLY, THE AIRBAG STORED INSIDE THE PASSENGER'S INSTRUMENT PANEL IS INSTANTANEOUSLY
EXPANDED TO SOFTEN THE SHOCK TO A PASSENGER.
