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.

WHEN THE IGNITION SW IS TURNED TO ACC POSITION THE CURRENT FROM THE CIG/RADIO FUSE FLOWS TO TERMINAL 1 OF THE
SHIFT LOCK ECU. WHEN THE IGNITION SW IS TURNED TO ON POSITION THE CURRENT FROM THE ECU±IG FUSE FLOWS TO
TERMINAL 3 OF THE ECU.
1. SHIFT LOCK MECHANISM
WITH THE IGNITION SW ON, WHEN A SIGNAL THAT THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) AND A SIGNAL THAT
THE SHIFT LEVER IS PUT IN ªPº POSITION (CONTINUITY BETWEEN P1 AND P OF THE SHIFT LOCK CONTROL SW) IS INPUT TO THE
ECU, THE ECU OPERATES AND CURRENT FLOWS FROM TERMINAL 3 OF THE ECU " TERMINAL SL+ OF THE SHIFT LOCK
SOLENOID " SOLENOID " TERMINAL SL± " TERMINAL 5 OF THE ECU " GROUND. THIS CAUSES THE SHIFT LOCK SOLENOID TO
TURN ON (PLATE STOPPER DISENGAGES) AND THE SHIFT LEVER CAN SHIFT INTO OTHER POSITION THAN THE ªPº POSITION.
2. KEY INTERLOCK MECHANISM
WITH THE IGNITION SW IN ON OR ACC POSITION, WHEN THE SHIFT LEVER IS PUT IN ªPº POSITION (NO CONTINUITY BETWEEN P2
AND P OF SHIFT LOCK CONTROL SW), THE CURRENT FLOWING FROM TERMINAL 4 OF THE ECU " KEYINTERLOCK SOLENOID IS
CUT OFF. THIS CAUSES THE KEYINTERLOCK SOLENOID TO TURN OFF (LOCK LEVER DISENGAGES FROM LOCK POSITION) AND
THE IGNITION KEY CAN BE TURNED FROM ACC TO LOCK POSITION.
