1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–1 ES SFI SYSTEM PRECAUTION NOTICE: • Perform RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM (See page AX-14). • Perform REGISTRATION (VIN registration) when replacing the ECM (See page ES-13). HINT: Initialization cannot be completed by only removing the battery. ES–2 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES DEFINITION OF TERMS Terms Definition Monitor Description Description of what ECM monitors and how detects malfunctions (monitoring purpose and details). Related DTCs Group of diagnostic trouble codes that are output by ECM based on same malfunction detection logic. Typical Enabling Condition Preconditions that allow ECM to detect malfunctions. With all preconditions satisfied, ECM sets DTC when monitored value(s) exceeds malfunction threshold(s). Sequence of Operation Order of monitor priority, applied if multiple sensors and components involved in single malfunction detection process. Each sensor and component monitored in turn, when previous detection operation completed. Required Sensor/Components Sensors and components used by ECM to detect each malfunction. Frequency of Operation Number of times ECM checks for each malfunction during each driving cycle. "Once per driving cycle" means ECM only performs checks for that malfunction once during single driving cycle. "Continuous" means ECM performs checks for that malfunction whenever enabling conditions met. Duration Minimum time for which ECM must detect continuous deviation in monitored value(s) in order to set DTC. Timing begins when Typical Enabling Conditions met. Malfunction Thresholds Value, beyond which, ECM determines malfunctions exist and sets DTCs. MIL Operation Timing of MIL illumination after defected. "Immediate" means ECM illuminates MIL as soon as malfunction detected. "2 driving cycle" means ECM illuminates MIL if same malfunction detected second time during next sequential driving cycle. 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–3 ES PARTS LOCATION PARK/NEUTRAL POSITION (PNP) SWITCH (A/T) ECM - EFI FUSE - EFI2 FUSE - AM2 FUSE - ETCS FUSE - INTEGRATION RELAY MASS AIR FLOW METER FUEL PUMP CHARCOAL CANISTER ASSEMBLY ENGINE ROOM RELAY BLOCK HEATED OXYGEN SENSOR (SENSOR 2) PURGE VSV A112592E01 ES–4 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES IGNITION COIL WITH IGNITER CAMSHAFT POSITION (CMP) SENSOR CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (OCV) CRANKSHAFT POSITION (CKP) SENSOR ENGINE COOLANT TEMPERATURE (ECT) SENSOR KNOCK SENSOR THROTTLE BODY FUEL INJECTOR AIR FUEL RATIO (A/F) SENSOR (SENSOR 1) A115674E02 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–5 ES MAIN BODY ECU (INSTRUMENT PANEL JUNCTION BLOCK) DLC3 COMBINATION METER - ACC RELAY - STOP FUSE - IGN FUSE ACCELERATOR PEDAL POSITION SENSOR CLUTCH START SWITCH (M/T) STOP LIGHT SWITCH A107890E04 ES–6 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES SYSTEM DIAGRAM M IG2 IGN IGSW STSW STOP To Battery Stop Light Ignition Coil No. 1 ST1- STP IGT1 IGT2 IGT3 IGT4 IGF1 Ignition Coil No. 2 Ignition Coil No. 3 Ignition Coil No. 4 ACCR STAR Park/Neutral Position Switch (*1) ST ST AM2 MAIN Battery EFI MREL FC BATT +B +BM STA +B2 EFI C/OPN Fuel Pump IGN ETCS To Starter To ACC Relay Stop Light Switch Ignition Switch Clutch Start Switch (*2) *1: A/T *2: M/T ECM A112578E01 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–7 ES M #10 Injector No. 1 #20 Injector No. 2 #30 Injector No. 3 #40 Injector No. 4 Purge VSV PRG Air-Fuel Ratio Sensor HA1A HT1B OX1B EX1B VG E2G THA ETHA VPMP VCPP PPMP EPPM MPMP IC IC Throttle Actuator Throttle Position Sensor GE01 M- M+ ETA VCTA VTA2 VTA1 KNK1 EKNK Heated Oxygen Sensor Mass Air Flow Meter Knock Sensor Leak Detection Pump Canister Pressure Sensor Vent Valve Canister Pump Module EFI2 ALT Generator W SPD Combination Meter A1A- A1A+ ECM A112579E01 ES–8 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES M TACH TC CANH CANL Engine Coolant Temperature Sensor Camshaft Position Sensor Crankshaft Position Sensor Accelerator Pedal Position Sensor IC IC To DEF Relay TAIL Tail Light THW G2+ NE- NE+ EPA2 VCPA DLC3 FAN FAN2 OC1+ Immobiliser Code ECU OC1- IMI IMO E0M To CAN BUS RDI ECU-IG FAN No. 1 FAN No. 2 Fan Resistor Cooling Fan Motor Camshaft Timing Oil Control Valve VPA EPA VCP2 VPA2 ETHW ID/UP/MIR HTR Defogger ELS3 ELS E1 ME01 E01 E04 EC E02 E03 ECM A112580E01 1NZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–9 ES HOW TO PROCEED WITH TROUBLESHOOTING HINT: *: Use the intelligent tester.
