TAILLIGHT (S/D, C/P)
WHEN THE LIGHT CONTROL SW IS TURNED TO TAIL OR HEAD POSITION, THE CURRENT FLOWS TO TERMINAL 3 OF THE LIGHT
FAILURE SENSOR THROUGH THE TAIL FUSE.
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FLOWS FROM THE GAUGE FUSE TO TERMINAL 8 OF THE LIGHT FAILURE
SENSOR, AND ALSO FLOWS THROUGH THE REAR LIGHTS WARNING LIGHT TO TERMINAL 4 OF THE LIGHT FAILURE SENSOR.
TAILLIGHT DISCONNECTION WARNING
WHEN THE IGNITION SW ON AND THE LIGHT CONTROL SW TURNED TO TAIL OR HEAD POSITION, IF THE TAILLIGHT CIRCUIT IS
OPEN, THE LIGHT FAILURE SENSOR DETECTS THE FAILURE BY THE CHANGE IN CURRENT FLOWING FROM TERMINAL 3 OF THE
LIGHT FAILURE SENSOR TO TERMINAL 9 AND THE WARNING CIRCUIT OF THE LIGHT FAILURE SENSOR IS ACTIVATED.
AS A RESULT, THE CURRENT FLOWS FLOM TERMINAL 4 OF THE LIGHT FAILURE SENSOR " TERMINAL 11 " GROUND AND TURNS
THE REAR LIGHT WARNING LIGHT ON, WHICH REMAINS ON UNTIL THE LIGHT CONTROL SW IS TURNED OFF.

CURRENT ALWAYS FLOWS TO TERMINAL 8 OF THE DOOR LOCK CONTROL RELAY THROUGH THE POWER FUSE.
WHEN THE IGNITION SW IS TURNED ON, THE CURRENT FLOWING THROUGH THE GAUGE FUSE FLOWS THROUGH THE COIL SIDE
OF THE POWER MAIN RELAY TO GROUND, CAUSING THE RELAY TO OPERATE. THE CURRENT FLOWING THROUGH THE POWER
FUSE FLOWS TO THE LH DOOR LOCK CONTROL SW, CAUSING THE INDICATOR LIGHT TO LIGHT UP.
1. MANUAL LOCK OPERATION
WHEN THE DOOR LOCK CONTROL SW AND KEY SW ARE PUSHED TO LOCK POSITION, A LOCK SIGNAL IS INPUT TO TERMINAL 10,
12 OF THE DOOR LOCK CONTROL RELAY AND CAUSES THE RELAY TO FUNCTION. CURRENT FLOWS FROM TERMINAL 8 OF THE
RELAY " TERMINAL 4 " TERMINAL 4 OF THE DOOR LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 7 (C/P FRONT DOOR),
OF THE DOOR LOCK MOTOR TERMINAL 2 OF THE BACK DOOR LOCK MOTOR " TERMINAL 2 OF THE DOOR LOCK MOTORS, (EX.
C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT DOOR) OF THE DOOR LOCK MOTOR TERMINAL 1 OF THE BACK DOOR LOCK
MOTOR " TERMINAL 3 OF THE RELAY " TERMINAL 16 " TO GROUND AND THE DOOR LOCK MOTOR CAUSES THE DOOR TO
LOCK.
2. MANUAL UNLOCK OPERATION
WHEN THE DOOR LOCK CONTROL SW AND KEY SW RH TO UNLOCK POSITION, AN UNLOCK SIGNAL IS INPUT TO TERMINAL 11, 13
OF THE DOOR LOCK RELAY AND CAUSES THE RELAY TO FUNCTION. CURRENT FLOWS FROM TERMINAL 8 OF THE RELAY "
TERMINAL 3 " TERMINAL 2 OF THE DOOR LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT DOOR) OF THE
DOOR LOCK MOTOR TERMINAL 1 OF THE BACK DOOR LOCK MOTOR " TERMINAL 4 OF THE DOOR LOCK MOTORS, (EX. C/P
FRONT DOOR) OR TERMINAL 7 (C/P FRONT DOOR), OF THE DOOR LOCK MOTOR TERMINAL 2 OF THE BACK DOOR LOCK MOTOR "
TERMINAL 4 OF THE RELAY " TERMINAL 16 " TO GROUND AND DOOR LOCK MOTORS CAUSES DOOR TO UNLOCK.
3. DOUBLE OPERATION UNLOCK OPERATION
WHEN THE DOOR LOCK KEY SW (DRIVER'S) IS TURNED TO THE UNLOCK SIDE, ONLY THE DRIVER'S DOOR IS MECHANICALLY
UNLOCKED. TURNING THE DOOR LOCK KEY SW (DRIVER'S) TO THE UNLOCK SIDE CAUSES A SIGNAL TO BE INPUT TO TERMINAL 9
OF THE RELAY, AND IF THE SIGNAL IS INPUT AGAIN WITHIN 3 SECONDS BY TURNING THE SW TO THE UNLOCK SIDE AGAIN,
CURRENT FLOWS TERMINAL 3 " TERMINAL 2 OF DOOR LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT
DOOR) OF THE DOOR LOCK MOTOR TERMINAL 1 OF THE BACK DOOR LOCK MOTOR " TERMINAL 4 OF THE DOOR LOCK MOTORS,
(EX. C/P FRONT DOOR) OR TERMINAL 7 (C/P FRONT DOOR), OF THE DOOR LOCK MOTOR TERMINAL 2 OF THE BACK DOOR LOCK
MOTOR " TERMINAL 4 OF THE RELAY " TERMINAL 16 " GROUND, CAUSING THE DOOR LOCK MOTORS TO OPERATE AND
UNLOCK THE DOORS.
4. IGNITION KEY REMINDER OPERATION
*OPERATING DOOR LOCK KNOB (OPERATION OF DOOR LOCK MOTORS)
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE DOOR IS OPENED AND LOCKED USING DOOR LOCK
KNOB (DOOR LOCK MOTOR), THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCKED SOON BY THE FUNCTION OF RELAY.
AS A RESULT, THE CURRENT FLOWS FROM TERMINAL 8 OF THE RELAY " TERMINAL 3 " TERMINAL 2 OF THE DOOR LOCK
MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT DOOR) OF THE DOOR LOCK MOTOR TERMINAL 2 OF THE BACK
DOOR LOCK MOTOR " TERMINAL 4 OF THE DOOR LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 7 (C/P FRONT DOOR),
OF THE DOOR LOCK MOTOR TERMINAL 1 OF THE BACK DOOR LOCK MOTOR " TERMINAL 4 OF THE RELAY " TERMINAL 16 "
TO GROUND AND CAUSES ALL THE DOORS TO UNLOCK.
*OPERATING DOOR LOCK CONTROL SW OR DOOR LOCK KEY SW
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE DOOR IS OPENED AND LOCKED USING DOOR LOCK
CONTROL SW OR KEY SW, THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCK BY THE FUNCTION OF SW CONTAINED IN
MOTORS, WHICH THE SIGNAL IS INPUT TO TERMINAL 6 (DRIVER'S) OR 5 (PASSENGER'S) OF THE RELAY. ACCORDING TO THIS
INPUT SIGNAL, THE CURRENT IN ECU FLOWS FROM TERMINAL 8 OF THE RELAY " TERMINAL 3 " TERMINAL 2 OF THE DOOR
LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT DOOR) OF THE DOOR LOCK MOTOR TERMINAL 2 OF THE
BACK DOOR LOCK MOTOR " TERMINAL 4 OF THE DOOR LOCK MOTORS, TERMINAL 1 OF THE BACK DOOR LOCK MOTOR "
TERMINAL 4 OF THE RELAY " TERMINAL 16 " TO GROUND AND CAUSES ALL THE DOOR TO UNLOCK.
*IN CASE OF KEY LESS LOCK
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE UNLOCK FUNCTION IS DISTURBED MORE THAN 0.2
SECONDS, FOR EXAMPLE PUSHING THE DOOR LOCK KNOB ETC., THE DOOR HOLDS ON LOCK CONDITION. CLOSING THE DOOR
AFTER, DOOR COURTESY SW INPUTS THE SIGNAL INTO TERMINAL 2 OR 14 OF THE RELAY. BY THIS INPUT SIGNAL, THE ECU
WORKS AND CURRENT FLOWS FROM TERMINAL 8 OF THE RELAY " TERMINAL 3 " TERMINAL 2 OF THE DOOR LOCK MOTORS,
(EX. C/P FRONT DOOR) OR TERMINAL 5 (C/P FRONT DOOR) OF THE DOOR LOCK MOTOR TERMINAL 1 OF THE BACK DOOR LOCK
MOTOR " TERMINAL 4 OF THE DOOR LOCK MOTORS, (EX. C/P FRONT DOOR) OR TERMINAL 7 (C/P FRONT DOOR), OF THE
DOOR LOCK MOTOR TERMINAL 2 OF THE BACK DOOR LOCK MOTOR " TERMINAL 4 OF THE RELAY " TERMINAL 16 " TO
GROUND AND CAUSES ALL THE DOORS TO UNLOCK.

ABS (ANTI±LOCK BRAKE SYSTEM) (TMC MADE)
THIS SYSTEM CONTROLS THE RESPECTIVE BRAKE FLUID PRESSURES ACTING ON THE DISC BRAKE CYLINDERS OF THE RIGHT
FRONT WHEEL, LEFT FRONT WHEEL AND REAR WHEELS WHEN THE BRAKES ARE APPLIED IN A PANIC STOP SO THAT THE
WHEELS DO NOT LOCK. THIS RESULTS IN IMPROVED DIRECTIONAL STABILITY AND STEERABILITY DURING PANIC BRAKEING.
1. INPUT SIGNALS
(1) SPEED SENSOR SIGNAL
THE SPEED OF THE WHEELS IS DETECTED AND INPUT TO TERMINALS FL+, FR+, RL+ AND RR+ OF THE ABS ECU.
(2) STOP LIGHT SW SIGNAL
A SIGNAL IS INPUT TO TERMINAL STP OF THE ABS ECU WHEN BRAKE PEDAL IS OPERATED.
(3) PARKING BRAKE SW SIGNAL
A SIGNAL IS INPUT TO TERMINAL PKB OF THE ABS ECU WHEN THE PARKING BRAKE IS OPERATED.
2. SYSTEM OPERATION
DURING SUDDEN BRAKEING THE ABS ECU, WHICH HAS SIGNALS INPUT FROM EACH SENSOR, CONTROLS THE CURRENT
FLOWING TO THE SOLENOID INSIDE THE ACTUATOR AND LETS THE HYDRAULIC PRESSURE ACTING ON EACH WHEEL CYLINDER
ESCAPE TO THE RESERVOIR. THE PUMP INSIDE THE ACTUATOR IS ALSO OPERATING AT THIS TIME AND IT RETURNS THE BRAKE
FLUID FROM THE RESERVOIR TO THE MASTER CYLINDER, THUS PREVENTING LOCKING OF THE VEHICLE WHEELS.
IF THE ECU JUDGES THAT THE HYDRAULIC PRESSURE ACTING ON THE WHEEL CYLINDER IS INSUFFICIENT, THE CURRENT
ACTING ON THE SOLENOID IS CONTROLLED AND THE HYDRAULIC PRESSURE IS INCREASED. HOLDING OF THE HYDRAULIC
PRESSURE IS ALSO CONTROLLED BY THE ECU, BY THE SAME METHOD AS ABOVE. BY REPEATED PRESSURE REDUCTION,
HOLDING AND INCREASE ARE REPLATED TO MAINTAIN VEHICLE STABILITY AND TO IMPROVE STEERBILITY DURING SUDDEN
BRAKING.
