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.

A) IF ANY OF THE FOLLOWING OPERATING CONDITIONS OCCURS DURING CRUISE CONTROL OPERATION, THE SET SPEED IS
ERASED, CURRENT FLOW TO MAGNETIC CLUTCH IS CUT OFF AND THE CRUISE CONTROL IS RELEASED. (MAIN SW TURNS OFF).
WHEN THIS OCCURS, THE IGNITION SW MUST BE TURNED OFF ONCE BEFORE THE MAIN SW WILL TURN ON AGAIN.
*OVER CURRENT TO TRANSISTOR DRIVING MOTOR AND/OR MAGNETIC CLUTCH.
*WHEN CURRENT CONTINUED TO FLOW TO THE MOTOR INSIDE THE ACTUATOR IN THE THROTTLE VALVE ªOPENº DIRECTION.
*OPEN CIRCUIT IN MOTOR AND/OR MAGNETIC CLUTCH.
*MOMENTARY INTERRUPTION OF VEHICLE SPEED SIGNAL.
*SHORT CIRCUIT IN CRUISE CONTROL SW.
*MOTOR DOES NOT OPERATE DESPITE THE MOTOR DRIVE SIGNAL BEING OUTPUT.
B) IF ANY OF THE FOLLOWING CONDITIONS OCCURS DURING CRUISE CONTROL OPERATION, THE SET SPEED IS ERASED AND
THE CRUISE CONTROL IS RELEASED. CURRENT FLOW TO MAGNETIC CLUTCH IS CUT OFF UNTIL THE SET SW IS ªONº AGAIN.)
*WHEN THE VEHICLE SPEED HAS FALLEN BELOW THE MINIMUM SPEED LIMIT, APPROX. 40 KM/H (25 MPH)
*WHEN THE VEHICLE SPEED HAS FALLEN MORE THAN 16 KM/H (10 MPH) BELOW THE SET SPEED, E.G. ON AN UPWARD SLOPE.
*WHEN POWER TO THE CRUISE CONTROL SYSTEM IS MOMENTARILY CUT OFF.
C) IF ANY OF THE FOLLOWING CONDITIONS OCCURS DURING CRUISE CONTROL OPERATION, THE CRUISE CONTROL IS
RELEASED.
*OPEN CIRCUIT FOR TERMINAL 1 OF CRUISE CONTROL ECU.
8. AUTOMATIC TRANSMISSION CONTROL FUNCTION
*IN OVERDRIVE. IF THE VEHICLE SPEED BECOMES LOWER THAN THE OVERDRIVE CUT SPEED (SET SPEED MINUS APPROX. 4
KM/H, 2.5 MPH) DURING CRUISE CONTROL OPERATION, SUCH AS DRIVING UP A HILL, THE OVERDRIVE IS RELEASED AND THE
POWER INCREASED TO PREVENT A REDUCTION IN VEHICLE SPEED.
*AFTER RELEASING THE OVERDRIVE, IF VEHICLE SPEED BECOMES HIGHER THAN THE OVERDRIVE RETURN SPEED (SET
SPEED MINUS APPROX. 2 KM/H, 1.2 MPH) AND THE ECU JUDGES BY THE SIGNALS FROM POTENTIOMETER OF THE ACTUATOR
THAT THE UPWARD SLOPE HAS FINISHED, OVERDRIVE IS RESUMED AFTER A WHILE.
