SYSTEM OUTLINE
THE SRS (SUPPLEMENTAL RESTRAINT SYSTEM) AIRBAG IS A DRIVER PROTECTION DEVICE WHICH HAS A SUPPLEMENTAL ROLE
TO THE SEAT BELTS.
CURRENT FLOWS CONSTANTLY TO TERMINAL (A) 4 OF THE CENTER AIRBAG SENSOR ASSEMBLY. WHEN THE IGNITION SW IS
TURNED TO ACC OR ON, CURRENT FROM THE RAD & CIG FUSE FLOWS TO TERMINAL (A) 3 OF THE CENTER AIRBAG SENSOR
ASSEMBLY. ONLY WHEN THE IGNITION SW IS ON DOES THE CURRENT FROM THE GAUGE FUSE FLOW TO TERMINAL (A) 1. AND
THE CURRENT FROM THE AM1 FUSE TO TERMINAL (A) 2.
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 MERCURY SW BUILT INTO THE CENTER AIRBAG
SENSOR ASSEMBLY IS ON AND THE CENTER AIRBAG SENSOR IS ON, FRONT AIRBAG SENSORS ARE OFF), CURRENT FROM THE
RAD & CIG, GAUGE OR AM1 FUSE FLOW TO TERMINAL (A) 8 OF THE CENTER AIRBAG SENSOR ASSEMBLY

WHEN THE MERCURY SW 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 RAD & CIG, GAUGE OR AM1 FUSE FLOWS TO TERMINALS (A) 8
OF THE CENTER AIRBAG SENSOR ASSEMBLY

TERMINAL (C) 2 OR (B) 1 OF CENTER AIRBAG SENSOR ASSEMBLY
GROUND.
WHEN THE MERCURY SW 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.
THE REASON WHY THERE ARE MULTIPLE POWER SOURCES AND GROUND POINTS IS SO THAT IN THE EVENT THAT ONE OR TWO
OF THE POWER SOURCES AND GROUND POINTS DO NOT WORK FOR SOME REASON, THE REMAINING POWER SOURCE AND
GROUND POINT WILL BE AVAILABLE TO COMPENSATE.
