1 ENGINE CONTOL (S-FE) SYSTEM OUTLINE THIS SYSTEM UTILIZES AN ENGINE CONTOL MODULE AND MAINTAINS OVEALL CONTOL OF THE ENGINE, TANSMISSION AND SO ON. AN OUTLINE OF THE ENGINE CONTOL IS EXPLAINED HEE.. INPUT SIGNALS () ENGINE COOLANT TEMP. SIGNAL SYSTEM THE ENGINE COOLANT TEMP. SENSO DETECTS THE ENGINE COOLANT TEMP. AND HAS A UILT-IN THEMISTO ITH A ESISTANCE HICH VAIES ACCODING TO THE ENGINE COOLANT TEMP. THUS THE ENGINE COOLANT TEMP. IS INPUT IN THE FOM OF A CONTOL SIGNAL INTO TEMINAL TH OF THE ENGINE CONTOL MODULE. () INTAKE AI TEMP. SIGNAL SYSTEM THE INTAKE AI TEMP. SENSO DETECTS THE INTAKE AI TEMP., HICH IS INPUT AS A CONTOL SIGNAL INTO TEMINAL THA OF THE ENGINE CONTOL MODULE. () OXYGEN SENSO SIGNAL SYSTEM THE OXYGEN DENSITY IN THE EXHAUST GASES IS DETECTED AND INPUT AS A CONTOL SIGNAL INTO TEMINAL OX AND OX OF THE ENGINE CONTOL MODULE. (4) PM SIGNAL SYSTEM CANKSHAFT POSITION AND ENGINE PM AE DETECTED Y THE PICK-UP COIL INSTALLED INSIDE THE DISTIUTO. CANKSHAFT POSITION IS INPUT AS A CONTOL SIGNAL INTO TEMINALS NE OF THE ENGINE CONTOL MODULE, AND PM IS INPUT INTO TEMINAL G+. () THOTTLE SIGNAL SYSTEM THE THOTTLE POSITION SENSO DETECTS THE THOTTLE VALVE OPENING ANGLE, HICH IS INPUT AS A CONTOL SIGNAL INTO TEMINAL VTA OF THE ENGINE CONTOL MODULE. () VEHICLE SPEED SIGNAL SYSTEM THE VEHICLE SPEED SENSO, INSTALLED INSIDE THE TANSMISSION, DETECTS THE VEHICLE SPEED AND INPUTS A CONTOL SIGNAL INTO TEMINAL SPD OF THE ENGINE CONTOL MODULE. (7) PAK/NEUTAL POSITION S SIGNAL SYSTEM THE PAK/NEUTAL POSITION S DETECTS HETHE THE SHIFT POSITION AE IN NEUTAL, PAKING O NOT, AND INPUTS A CONTOL SIGNAL INTO TEMINAL NS OF THE ENGINE CONTOL MODULE. (8) A/C S SIGNAL SYSTEM THE A/C AMPLIFIE INPUTS THE A/C OPEATIONS INTO TEMINAL AC OF THE ENGINE CONTOL MODULE AS A CONTOL SIGNAL. (9) ATTEY SIGNAL CICUIT VOLTAGE IS CONSTANTLY APPLIED TO TEMINAL ATT OF THE ENGINE CONTOL MODULE. HEN THE IGNITION S IS TUNED ON, THE VOLTAGE FO ENGINE CONTOL MODULE STAT-UP POE SUPPLY IS APPLIED TO TEMINALS + OF ENGINE CONTOL MODULE VIA EFI MAIN ELAY. (0) INTAKE AI VOLUME SIGNAL SYSTEM INTAKE AI VOLUME IS DETECTED Y THE MANIFOLD ASOLUTE PESSUE SENSO (FO MANIFOLD PESSUE) AND IS INPUT AS A CONTOL SIGNAL INTO TEMINAL PIM OF THE ENGINE CONTOL MODULE. () STATE SIGNAL CICUIT TO CONFIM HETHE THE ENGINE IS CANKING, THE VOLTAGE APPLIED TO THE STATE MOTO DUING CANKING IS DETECTED AND THE SIGNAL IS INPUT INTO TEMINAL STA OF THE ENGINE CONTOL MODULE AS A CONTOL SIGNAL. () ENGINE KNOCK SIGNAL CICUIT ENGINE KNOCKING IS DETECTED Y KNOCK SENSO AND THE SIGNAL IS INPUT INTO TEMINAL KNK AS A CONTOL SIGNAL. () ELECTICAL LOAD SIGNAL SYSTEM THE SIGNAL HEN SYSTEMS SUCH AS THE EA INDO DEFOGGE, HEADLIGHTS, ETC. HICH CAUSE A HIGH ELECTICAL UDEN AE ON IS INPUT TO TEMINAL ELS AS A CONTOL SIGNAL. 88

2 . CONTOL SYSTEM * SFI (SEQUENTIAL MULTIPOT FUEL INJECTION) SYSTEM THE SFI SYSTEM MONITOS THE ENGINE CONDITION THOUGH THE SIGNALS, HICH AE INPUT FOM EACH SENSO (INPUT SIGNALS FOM () TO () ETC.) TO THE ENGINE CONTOL MODULE. THE EST FUEL INJECTION VOLUME IS DECIDED ASED ON THIS DATA AND THE POGAM MEMOIZED Y THE ENGINE CONTOL MODULE, AND THE CONTOL SIGNAL IS OUTPUT TO TEMINALS #0, #0, #0 AND #40 OF THE ENGINE CONTOL MODULE TO OPEATE THE INJECTO (INJECT THE FUEL). THE SFI SYSTEM PODUCES CONTOL OF FUEL INJECTION OPEATION Y THE ENGINE CONTOL MODULE IN ESPONSE TO THE DIVING CONDITIONS. * ESA (ELECTONIC SPAK ADVANCE) SYSTEM THE ESA SYSTEM MONITOS THE ENGINE CONDITION THOUGH THE SIGNALS, HICH AE INPUT TO THE ENGINE CONTOL MODULE FOM EACH SENSO (INPUT SIGNALS FOM (), (), (4) TO () ETC.) THE EST IGNITION TIMING IS DETECTED ACCODING TO THIS DATA AND THE MEMOIZED DATA IN THE ENGINE CONTOL MODULE, AND THE CONTOL SIGNAL IS OUTPUT TO TEMINAL IGT. THIS SIGNAL CONTOLS THE IGNITE TO POVIDE THE EST IGNITION TIMING FO THE DIVING CONDITIONS. * IAC (IDLE AI CONTOL) SYSTEM THE IAC SYSTEM (OTAY SOLENOID TYPE) INCEASES THE PM AND POVIDES IDLING STAILITY FO FAST IDLE-UP HEN THE ENGINE IS COLD AND HEN THE IDLE SPEED HAS DOPPED DUE TO ELECTICAL LOAD, ETC. THE ENGINE CONTOL MODULE EVALUATES THE SIGNALS FOM EACH SENSO (INPUT SIGNALS (), (4) TO (8), () ETC.), OUTPUTS CUENT TO TEMINALS SO AND SC, AND CONTOLS THE IDLE AI CONTOL VALVE. * FUEL PUMP CONTOL SYSTEM THE ENGINE CONTOL MODULE OPEATION OUTPUTS TO TEMINAL FC AND CONTOLS THE CICUIT OPENING ELAY. THUS CONTOLS THE FUEL PUMP DIVE SPEED IN ESPONSE TO CONDITIONS. * EG CONTOL SYSTEM THE EG CUT CONTOL SYSTEM CONTOLS THE VSV (EG SYSTEM) Y EVALUATING THE SIGNALS FOM EACH SENSO HICH AE INPUT TO THE ENGINE CONTOL MODULE (INPUT SIGNALS (), (), (), (9) ETC.) AND Y SENDING OUTPUT TO TEMINAL EG OF THE ENGINE CONTOL MODULE. * A/C CUT CONTOL SYSTEM HEN THE VEHICLE SUDDENLY ACCELEATES FOM LO ENGINE SPEED, THIS SYSTEM CUTS OFF AI CONDITIONING OPEATION FO A FIXED PEIOD OF TIME IN ESPONSE TO THE VEHICLE SPEED AND THOTTLE VALVE OPENING ANGLE IN ODE TO MAINTAIN ACCELEATION PEFOMANCE. THE ENGINE CONTOL MODULE ECEIVES INPUT SIGNALS ((), () ETC.), AND OUTPUTS SIGNALS TO TEMINAL ACT.. DIAGNOSIS SYSTEM ITH THE DIAGNOSIS SYSTEM, HEN THEE IS A MALFUNCTIONING IN THE ENGINE CONTOL MODULE SIGNAL SYSTEM, THE MALFUNCTION SYSTEM IS ECODED IN THE MEMOY. THE MALFUNCTIONING SYSTEM CAN THEN E FOUND Y EADING THE DISPLAY (CODE) OF THE MALFUNCTION INDICATO LAMP. 4. FAIL-SAFE SYSTEM HEN A MALFUNCTION OCCUS IN ANY SYSTEM, IF THEE IS A POSSIILITY OF ENGINE TOULE EING CAUSED Y CONTINUED CONTOL ASED ON THE SIGNALS FOM THAT SYSTEM, THE FAIL-SAFE SYSTEM EITHE CONTOLS THE SYSTEM Y USING DATA (STANDAD VALUES) ECODED IN THE ENGINE CONTOL MODULE MEMOY O ELSE STOPS THE ENGINE. 89
