3 HO TO USE THIS MNU This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (ll circuit diagrams are shown with the switches in the OFF position.) hen troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. hen the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use elay ocation and Electrical iring outing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. iring related to each system is indicated in each system circuit by arrows (from, to ). hen overall connections are required, see the Overall Electrical iring Diagram at the end of this manual. 00 TOYOT TCOM (ED0U)

6 HO TO USE THIS MNU [O] [P] SYSTEM OUTINE Current is applied at all times through the STOP fuse to TEMIN of the stop light S. hen the ignition S is turned on, current flows from the GUGE fuse to TEMIN 8 of the light failure sensor, and also flows through the rear lights warning light to TEMIN of the light failure sensor. STOP IGHT DISCONNECTION NING hen the ignition S is turned on and the brake pedal is pressed (Stop light S on), if the stop light circuit is open, the current flowing from TEMIN 7 of the light failure sensor to TEMINS, changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. s a result, the current flows from TEMIN of the light failure sensor to TEMIN to GOUND and turns the rear lights warning light on. y pressing the brake pedal, the current flowing to TEMIN 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition S is turned off.

72 ENGINE CONTO (VZ-FE) SYSTEM OUTINE The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission, etc. n outline of engine control is given here.. INPUT SIGN () Engine coolant temp. signal system The engine coolant temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance which varies according to the water temp. Thus the engine coolant temp. is input in the form of a control signal to TEMIN TH of the engine control module. () Intake air temp. signal system The intake air temp. sensor is installed inside the mass air flow meter and detects the intake air temp., which is input as a control signal to TEMIN TH of the engine control module. () Heated oxygen sensor signal system The oxygen density in the exhaust emissions is detected and input as a control signal to TEMIN OXS of the engine control module. To maintain stable detection performance by the heated oxygen sensor, a heater is used for warming the sensor. The heater is also controlled by the engine control module (HTS). () PM signal system Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor, camshaft position is input as a control signal to TEMIN G of the engine control module, and engine PM is input to TEMIN NE+. () Throttle signal system The throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TEMIN VT of the engine control module. (6) Vehicle speed signal system The vehicle speed sensor detects the vehicle speed and inputs a control signal to TEMIN SP of the engine control module via the combination meter. (7) /C S signal system The operating voltage of the /C magnetic clutch is detected and input in the form of a control signal to TEMIN C of the engine control module. (8) attery signal system Voltage is constantly applied to TEMIN TT of the engine control module. hen the ignition S is turned to on, voltage for engine control module operation is applied via the EFI relay to TEMIN + of the engine control module. (9) Intake air volume signal system Intake air volume is detected by the mass air flow meter and a signal is input into TEMIN VG of the engine control module as a control signal. (0) Stop light S signal system The stop light S is used to detect whether or not the vehicle is braking and the information is input as a control signal to TEMIN STP of the engine control module. () Starter signal system To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as a control signal to TEMIN ST of the engine control module. () Engine knock signal system Engine knocking is detected by the knock sensor and and the signals are input to TEMINS KNK and KNK of the engine control module. () D signal system hether or not the vehicle is operating in D mode is determined, and a control signal is input to TEMIN D of the engine control module. () ir fuel ratio signal system The air fuel ratio is detected and input as a control signal into TEMIN F+ of the engine control module TOYOT TCOM (ED0U)
