2. CONTROL SYSTEM
*SFI (SEQUENTIAL MULTIPORT FUEL INJECTION) (EFI (ELECTRONIC FUEL INJECTION) SYSTEM
THE EFI SYSTEM MONITORS THE ENGINE CONDITION THROUGH THE SIGNALS INPUT FROM EACH SENSOR (INPUT SIGNALS
FROM (1) TO (12) ETC.). THE BEST FUEL INJECTION VOLUME IS DECIDED BASED ON THIS DATA AND THE PROGRAM MEMORIZED
BY THE ENGINE CONTROL MODULE (ECU), AND THE CONTROL SIGNAL IS OUTPUT TO TERMINALS #10, #20, #30, #40, #50 AND #60
OF THE ENGINE CONTROL MODULE (ECU) TO OPERATE THE INJECTOR (INJECT THE FUEL). THE EFI SYSTEM PRODUCES
CONTROL OF FUEL INJECTION OPERATION BY THE ENGINE CONTROL MODULE (ECU) IN RESPONSE TO THE DRIVING
CONDITIONS.
*ESA (ELECTRONIC SPARK ADVANCE) SYSTEM
THE ESA SYSTEM MONITORS THE ENGINE CONDITION THROUGH THE SIGNALS INPUT TO THE ENGINE CONTROL MODULE (ECU)
FROM EACH SENSOR (INPUT SIGNALS FROM (1), (3), (4) TO (12) ETC.). THE BEST IGNITION TIMING IS DECIDED ACCORDING TO
THIS DATA AND THE MEMORIZED DATA IN THE ENGINE CONTROL MODULE (ECU) AND THE CONTROL SIGNAL IS OUTPUTS TO
TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5 AND IGT6. THIS SIGNAL CONTROLS THE IGNITER TO PROVIDE THE BEST IGNITION
TIMING FOR THE DRIVING CONDITIONS.
*HEATED OXYGEN SENSOR (OXYGEN SENSOR) HEATER CONTROL SYSTEM
THE OXYGEN SENSOR HEATER CONTROL SYSTEM TURNS THE HEATER ON WHEN THE INTAKE AIR VOLUME IS LOW (TEMP. OF
EXHAUST EMISSIONS IS LOW), AND WARMS UP THE OXYGEN SENSOR (NO. 1 AND NO. 2) TO IMPROVE DETECTION
PERFORMANCE OF THE SENSOR.
THE ENGINE CONTROL MODULE (ECU) EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (9) TO (10)
ETC.), AND OUTPUT CURRENT TO TERMINALS HTL, HTR AND HTS AND CONTROL THE HEATER.
*IAC (IDLE AIR CONTROL (ISC)) SYSTEM
THE IAC (ISC) SYSTEM (ROTARY SOLENOID TYPE) INCREASES THE RPM AND PROVIDES IDLE STABILITY FOR FAST IDLE±UP
WHEN THE ENGINE IS COLD, AND WHEN THE IDLE SPEED HAS DROPPED DUE TO ELECTRICAL LOAD AND SO ON, THE ENGINE
CONTROL MODULE (ECU) EVALUATES THE SIGNALS FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (5), (8), (9) ETC.),
OUTPUTS CURRENT TO TERMINALS RSO AND RSC TO CONTROL IDLE AIR CONTROL VALVE.
*EGR CONTROL SYSTEM
THE EGR CONTROL SYSTEM DETECTS THE SIGNAL FROM EACH SENSOR (INPUT SIGNALS FROM (1), (4), (9), (10), ETC)., AND
OUTPUTS CURRENT TO TERMINAL EGR TO CONTROL THE EGR VALVE.
*ACIS (ACOUSTIC CONTROL INDUCTION SYSTEM)
ACIS INCLUDES A VALVE IN THE BULKHEAD SEPARATING THE SURGE TANK INTO TWO PARTS. THIS VALVE IS OPENED AND
CLOSED IN ACCORDANCE WITH THE DRIVING CONDITIONS TO CONTROL THE INTAKE MANIFOLD LENGTH IN TWO STAGES FOR
INCREASED ENGINE OUTPUT IN ALL RANGES FROM LOW TO HIGH SPEEDS.
THE ENGINE CONTROL MODULE (ECU) JUDGES THE ENGINE SPEED BY THE SIGNALS ((4), (5)) FROM EACH SENSOR AND
OUTPUTS SIGNALS TO THE TERMINAL ACIS TO CONTROL THE VSV (FOR OPENING AND CLOSING THE INTAKE CONTROL VALVE)
3. DIAGNOSIS SYSTEM
WITH THE DIAGNOSIS SYSTEM, WHEN THERE IS A MALFUNCTION IN THE ENGINE CONTROL MODULE (ECU) SIGNAL SYSTEM, THE
MALFUNCTIONING SYSTEM IS RECORDED IN THE MEMORY.
4. FAIL±SAFE SYSTEM
WHEN A MALFUNCTION HAS OCCURRED IN ANY SYSTEM, IF THERE IS A POSSIBILITY OF ENGINE TROUBLE BEING CAUSED BY
CONTINUED CONTROL BASED ON THE SIGNALS FROM THAT SYSTEM, THE FAIL±SAFE SYSTEM EITHER CONTROLS THE SYSTEM
BY USING DATA (STANDARD VALUES) RECORDED IN THE ENGINE CONTROL MODULE (ECU) MEMORY OR ELSE STOPS THE
ENGINE.

CURRENT FROM THE BATTERY IS ALWAYS FLOWING FROM THE FL MAIN " HEADLIGHT RELAY (COIL SIDE) " TERMINAL 5 OF THE
DAYTIME RUNNING LIGHT RELAY (MAIN) AND TERMINAL 14 OF THE DIMMER SW, HEADLIGHT RELAY (COIL SIDE) " TERMINAL 3 OF
THE INTEGRATION RELAY " TERMINAL 4 " TERMINAL 13 OF THE LIGHT CONTROL SW, FL MAIN " DAYTIME RUNNING LIGHT
RELAY NO. 2 (COIL SIDE) " TERMINAL 17 OF THE DAYTIME RUNNING LIGHT RELAY.
1. DAYTIME RUNNING LIGHT OPERATION
WHEN THE ENGINE IS STARTED, VOLTAGE GENERATED AT TERMINAL L OF THE GENERATOR (ALTERNATOR) IS APPLIED TO
TERMINAL 11 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN).
IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON) AT THIS TIME, THE RELAY IS NOT ENERGIZED, SO THE
DAYTIME RUNNING LIGHT SYSTEM DOES NOT OPERATE. IF THE PARKING BRAKE LEVER IS RELEASED (PARKING BRAKE LEVER
SW OFF), THE SIGNAL IS INPUT TO TERMINAL 8 OF THE RELAY. THIS ACTIVATES THE RELAY ALSO, CURRENT FROM FL MAIN
FLOWES TO DAYTIME RUNNING LIGHT RELAY NO. 2 (POINT SIDE) " HEAD (UPR±LH) FUSE " TERMINAL 1 OF THE HEAD LH±HI "
TERMINAL 2 " TERMINAL 2 OF THE HEAD RH±HI " TERMINAL 1 " TERMINAL 4 OF THE DAYTIME RUNNING LIGHT RELAY NO. 3 "
TERMINAL 2 " TO GROUND, SO BOTH TAIL AND HEADLIGHT UP.
THIS IS HOW THE DAYTIME RUNNING LIGHT SYSTEM OPERATES. ONCE THE DAYTIME RUNNING LIGHT SYSTEM OPERATES AND
HEAD HAVE LIGHT UP, HEAD REMAIN ON EVEN IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON).
EVEN IF THE ENGINE STALLS WITH THE IGNITION SW ON AND THERE IS NO VOLTAGE FROM TERMINAL L OF THE GENERATOR
(ALTERNATOR), HEAD REMAIN ON. IF THE IGNITION SW IS THEN TURNED OFF, AND HEAD ARE TURNED OFF.
IF THE ENGINE IS STARTED WHILE THE PARKING BRAKE LEVER IS RELEASED (PARKING BRAKE SW OFF), THE DAYTIME RUNNING
LIGHT SYSTEM OPERATES AND TAIL, HEADLIGHT UP AS THE ENGINE STARTS.
2. HEADLIGHT OPERATION
*(WHEN THE LIGHT CONTROL SW AT THE HEAD POSITION)
WHEN THE LIGHT CONTROL SW IS SET TO HEAD POSITION, THE CURRENT FLOWING TO THE HEADLIGHT RELAY (COIL SIDE)
FLOWS TO TERMINAL 3 OF THE INTEGRATION RELAY " TERMINAL 4 " TERMINAL 13 OF THE LIGHT CONTROL SW " TERMINAL 11
" GROUND, TURNING THE HEADLIGHT RELAY ON.
THIS CAUSES THE CURRENT FLOWING TO THE HEADLIGHT RELAY (POINT SIDE) " DRL FUSE " DAYTIME RUNNING LIGHT RELAY
NO. 3 (COIL SIDE) AND DAYTIME RUNNING LIGHT RELAY NO. 4 (COIL SIDE) " GROUND, TURNING THE DAYTIME RUNNING LIGHT
RELAY NO. 3 AND NO. 4 ON. ALSO, CURRENT FROM THE HEADLIGHT RELAY (POINT SIDE) TO HEAD (LWR) FUSES " TERMINAL 1
OF THE HEADLIGHTS (LO) " TERMINAL 2 " GROUND, SO THE HEADLIGHTS (LO) LIGHT UP.
*(DIMMER SW AT FLASH POSITION)
WHEN THE DIMMER SW IS SET TO FLASH POSITION, CURRENT FLOWS FROM HEADLIGHT RELAY (COIL SIDE) " TERMINAL 14 OF
THE DIMMER SW " TERMINAL 9 " GROUND, TURNING THE HEADLIGHT RELAY ON. AT THE SAME TIME, SIGNALS ARE OUTPUT
FROM TERMINAL 12 AND TERMINAL 14 OF THE DIMMER SW TO TERMINAL 16 AND TERMINAL 5 OF THE DAYTIME RUNNING LIGHT
RELAY (MAIN), ACTIVATING THE DAYTIME RUNNING LIGHT RELAY (MAIN) AND ALSO THE DAYTIME RUNNING LIGHT RELAY NO. 2.
WHEN THE HEADLIGHT RELAY AND DAYTIME RUNNING LIGHT RELAY (MAIN) ARE ACTIVATED, THE HEADLIGHTS (LO AND HI) THEN
LIGHT UP.
*(DIMMER SW AT HIGH POSITION)
WHEN THE LIGHT CONTROL SW IS SET TO HEAD POSITION, A SIGNAL IS OUTPUT FROM TERMINAL 13 OF THE LIGHT CONTROL SW
" TERMINAL 4 OF THE INTEGRATION RELAY " TERMINAL 3 " TERMINAL 5 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN).
WHEN THE DIMMER SW IS SET TO HIGH POSITION, A SIGNAL IS OUTPUT FROM TERMINAL 12 OF THE DIMMER SW TO TERMINAL 16
OF THE DAYTIME RUNNING LIGHT RELAY (MAIN). THESE SIGNALS ACTIVATE DAYTIME RUNNING LIGHT RELAY NO. 2, SO CURRENT
FLOWS FROM DAYTIME RUNNING LIGHT RELAY NO. 2 (POINT SIDE) " HEAD (UPR±LH) FUSE " TERMINAL 1 OF THE HEADLIGHT
