SRS (SUPPLEMENTAL RESTRAINT SYSTEM)
THE SRS (SUPPLEMENTAL RESTRAINT SYSTEM) 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, CURRENT FROM THE CIG/RADIO FUSE FLOWS TO TERMINAL 14 OF THE
CENTER AIRBAG SENSOR ASSEMBLY. ONLY WHEN THE IGNITION SW IS ON DOES THE CURRENT FROM THE IGN FUSE FLOW TO
TERMINAL 13.
IF AN ACCIDENT OCCURS WHILE DRIVING, DECELERATION CAUSED BY A FRONTAL IMPACT IS DETECTED BY EACH SENSOR AND
SWITCH, AND WHEN THE FRONTAL IMPACT EXCEEDS A SET LEVEL (WHEN THE SAFING SENSOR BUILT INTO THE CENTER AIRBAG
SENSOR ASSEMBLY IS ON AND THE CENTER AIRBAG SENSOR IS ON, FRONT AIRBAG SENSORS ARE OFF), CURRENT FROM THE
CIG/RADIO OR IGN FUSE FLOWS TO TERMINALS 2, 3 OF THE CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 1 OF THE AIRBAG
SQUIB → SQUIB → TERMINAL 2 → TERMINALS 1, 4 OF CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 6, TERMINAL 5 OR BODY
GROUND → GROUND.
WHEN THE SAFING SENSOR BUILT INTO THE CENTER AIRBAG SENSOR ASSEMBLY IS ON AND THE FRONT AIRBAG SENSOR LH OR
RH IS ON, CENTER AIRBAG SENSOR IS OFF CURRENT FROM THE CIG/RADIO OR IGN FUSE FLOWS TO TERMINALS 2, 3 OF THE
CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 1 OF THE AIRBAG SQUIB → SQUIB → TERMINAL 2 → TERMINALS 1, 4 OF
CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 8 OR 11 → TERMINAL 1 OF FRONT AIRBAG SENSOR → TERMINAL 2 →
TERMINAL 9 OR 10 OF CENTER AIRBAG SENSOR ASSEMBLY → TERMINAL 6, TERMINAL 5 OR BODY GROUND → GROUND.
WHEN THE SAFING SENSOR BUILT INTO THE CENTER AIRBAG SENSOR ASSEMBLY IS ON, AND THE FRONT AIRBAG SENSOR LH OR
RH IS ON AND CENTER AIRBAG SENSOR IS ON ONE OF THE ABOVE–MENTIONED CIRCUITS IS ACTIVATED SO THAT CURRENT
FLOWS TO THE AIRBAG SQUIB AND CAUSES IT TO OPERATE. THE BAG STORED INSIDE THE STEERING WHEEL PAD IS
INSTANTANEOUSLY EXPANDED TO SOFTEN THE SHOCK TO THE DRIVER.
