HOW TO USE THIS MANUAL B

This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.

The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)

When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.

When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors and ground points of each system circuit.Internal wiring for each junction block is also provided for better understanding ofconnection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.

Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

VOLTAGE CHECK

(a) Establish conditions in which voltage is present at the checkpoint.

Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (SW 2 off)

(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.

CONTINUITY AND RESISTANCE CHECK

(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.

(b) Contact the two leads of an ohmmeter to each of the checkpoints.

If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.

(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT

(a) Remove the blown fuse and disconnect all loads of the fuse.

(b) Connect a test light in place of the fuse.

(c) Establish conditions in which the test light comes on.

Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (Connect the

Relay) and SW 2 off (or Disconnect SW 2)

(d) Disconnect and reconnect the connectors while watching thetest light.The short lies between the connector where the test lightstays lit and the connector where the light goes out.

(e) Find the exact location of the short by lightly shaking theproblem wire along the body.

CAUTION:(a) Do not open the cover or the case of the ECU unless

absolutely necessary. (If the IC terminals are touched,the IC may be destroyed by static electricity.)

(b) When replacing the internal mechanism (ECU part) ofthe digital meter, be careful that no part of your body orclothing comes in contact with the terminals of leadsfrom the IC, etc. of the replacement part (spare part).

DISCONNECTION OF MALE AND FEMALECONNECTORS

To pull apart the connectors, pull on the connector itself, notthe wire harness.

1. SINGLE FILAMENT

CIGARETTE LIGHTERAn electric resistance heatingelement.

2. DOUBLE FILAMENT

CIRCUIT BREAKERBasically a reusable fuse, a circuitbreaker will heat and open if toomuch current flows through it.Some units automatically reset whencool, others must be manually reset.

HORNAn electric device which sounds aloud audible signal.

DIODEA semiconductor which allowscurrent flow in only one direction.

IGNITION COILConverts low–voltage DC currentinto high–voltage ignition current forfiring the spark plugs.

DIODE, ZENERA diode which allows current flow in onedirection but blocks reverse flow only upto a specific voltage. Above that potential,it passes the excess voltage. This acts asa simple voltage regulator.

LIGHTCurrent flow through a filamentcauses the filament to heat up andemit light.

PHOTODIODEThe photodiode is a semiconductorwhich controls the current flowaccording to the amount of light.

LED (LIGHT EMITTING DIODE)Upon current flow, these diodes emitlight without producing the heat of acomparable light.

DISTRIBUTOR, IIAChannels high–voltage current fromthe ignition coil to the individualspark plugs.

METER, ANALOGCurrent flow activates a magneticcoil which causes a needle to move,thereby providing a relative displayagainst a background calibration.

FUSEA thin metal strip which burns throughwhen too much current flows through it,thereby stopping current flow andprotecting a circuit from damage.

FUSIBLE LINK

METER, DIGITALCurrent flow activates one or manyLED’s, LCD’s, or fluorescentdisplays, which provide a relative ordigital display.

FUEL

FUSIBLE LINKA heavy–gauge wire placed in highamperage circuits which burns through onoverloads, thereby protecting the circuit.The numbers indicate the crosssectionsurface area of the wires.

(for Medium Current Fuse)

(for High Current Fuse or Fusible Link)

MOTORA power unit which convertselectrical energy into mechanicalenergy, especially rotary motion.

RELAYBasically, an electrically operatedswitch which may be normallyclosed (1) or open (2).Current flow through a small coilcreates a magnetic field which eitheropens or closes an attached switch.

1. NORMALLY CLOSED

2. NORMALLY OPEN

SWITCH, MANUALOpens and closescircuits, thereby

SPEAKERAn electromechanical device whichcreates sound waves from currentflow.

RELAY, DOUBLE THROWA relay which passes currentthrough one set of contacts or theother.

Opens and closescircuits, therebystopping (1) orallowing (2) currentflow.

1. NORMALLY OPEN

2. NORMALLY CLOSED

RESISTORAn electrical component with a fixedresistance, placed in a circuit toreduce voltage to a specific value.

SWITCH, DOUBLE THROWA switch which continuously passescurrent through one set of contactsor the other.

RESISTOR, TAPPEDA resistor which supplies two ormore different non adjustableresistance values.

SWITCH, IGNITIONA key operated switch with severalpositions which allows variouscircuits, particularly the primaryignition circuit, to becomeoperational.

RESISTOR, VARIABLE or RHEOSTATA controllable resistor with a variablerate of resistance.Also called a potentiometer orrheostat.

operational.

SENSOR (Thermistor)A resistor which varies its resistancewith temperature.

SWITCH, WIPER PARKAutomatically returns wipers to thestop position when the wiper switchis turned off.

(Reed Switch Type)

SENSOR, SPEEDUses magnetic impulses to openand close a switch to create a signalfor activation of other components.

TRANSISTORA solidstate device typically used asan electronic relay; stops or passescurrent depending on the voltageapplied at ”base”.

SHORT PINUsed to provide an unbrokenconnection within a junction block.

WIRESWires are always drawn asstraight lines on wiringdiagrams.Crossed wires (1) without ablack dot at the junction are

(1) NOT CONNECTED

SOLENOIDAn electromagnetic coil which formsa magnetic field when current flows,to move a plunger, etc.

black dot at the junction arenot joined;crossed wires (2) with ablack dot or octagonal ( )mark at the junction arespliced (joined)connections.

Memo

There are two types of wire harness for the instrument panel on xA.Type A : The wire harness that uses the color–coded wire.Type B : The wire harness that uses the same colored wire. (Not color–coded)

This means that there is a case where the wire harness used for even the samesection may have different colored wire depending on the models.Therefore, the wire colors are also mentioned in this manual as follows.

In case of using the same colored wires, each terminal number is printed on the wireas shown in the illustration on the left in order to distinguish each wiring.Be sure to connect the terminal to the same place as indicated by the terminalnumber printed on the wire after disconnecting the terminal from the connector.

Memo

There are two types of wire harness for the instrument panel on xA.Type A : The wire harness that uses the color–coded wire.Type B : The wire harness that uses the same colored wire. (Not color–coded)

This means that there is a case where the wire harness used for even the samesection may have different colored wire depending on the models.Therefore, the wire colors are also mentioned in this manual as follows.

In case of using the same colored wires, each terminal number is printed on the wireas shown in the illustration on the left in order to distinguish each wiring.Be sure to connect the terminal to the same place as indicated by the terminalnumber printed on the wire after disconnecting the terminal from the connector.

SCION xA (EM00D0U)

Power Window

When the ignition SW is turned on, the current flows from the GAUGE fuse through the POWER relay to GROUND, thus thePOWER relay is turned on and the current flows through the POWER fuse to TERMINAL 5 of the POWER relay toTERMINAL 3 to TERMINAL B of the power window master SW and TERMINAL B of the power window control SW front RH,Rear LH and RH.

1. Manual Operation (Power Window Master SW)When the power window master SW (Driver’s) is pushed down one step, the current flows from TERMINAL B of the powerwindow master SW to TERMINAL DD to TERMINAL 5 of the power window motor front LH to TERMINAL 4 to TERMINALDU of the power window master SW to TERMINAL E to GROUND, and the motor rotates to open the window. When thepower window master SW is pulled up one step, the current flows from TERMINAL B of the power window master SW toTERMINAL DU to TERMINAL 4 of the power window motor front LH to TERMINAL 5 to TERMINAL DD of the power windowmaster SW to TERMINAL E to GROUND, and the motor rotates in the opposite direction from open and closes the window.All the other windows are opened/closed by operating the respective power window master SW. When the window lock SWis pushed to the lock side, the ground circuit to the passenger’s window becomes open. As a result, even if Open/Closeoperation of the passenger’s window is attempted, the current from TERMINAL E of the power window master SW is notgrounded and the motor does not rotate, so the passenger’s window can not be operated and window lock occurs.

2. Auto Down Operation (Driver’s Window)When the power window master SW (Driver’s) is pushed down two steps, the power window master SW determines that it isAUTO operation and the current flows from TERMINAL B of the power window master SW to TERMINAL DD to TERMINAL5 of the power window motor front LH to TERMINAL 4 to TERMINAL DU of the power window master SW to TERMINAL E toGROUND. Because the hold circuit inside the power window master SW keeps the relay on the down side activated, thepower window motor continues operating even if the power window master SW is released. When the driver’s window is fullyopened, the hold circuit turns off and the relay on the down side turns off, and auto down operation is completed.

3. Stopping of Auto Down Operation (Driver’s Window)When the power window master SW (Driver’s) is pulled to the up side during auto down operation, a ground circuit opens inthe power window master SW and current does not flow from TERMINAL DU of the power window master SW to TERMINALE, so the motor stops, causing auto down operation to stop. If the power window master SW is pulled continuously, the motorrotates in the up direction in manual up operation.

4. Manual Operation (Power Window Control SW Front RH, Rear LH and RH)With the power window control SW (Front RH, rear LH or RH) pulled to the up side, current flows from TERMINAL B of thepower window control SW to TERMINAL U to power window motor to TERMINAL D of the power window control SW toTERMINAL SD to TERMINAL PD, RLD or RRD of the power window master SW to TERMINAL E to GROUND and rotatesthe power window motor (Front RH, rear LH or RH) in the up direction. Up operation continues only while the power windowcontrol SW is pulled to the up side. When the window descends, the current flowing to the motor flows in the oppositedirection, and the motor rotates in reverse. When the window lock SW is pushed to the lock side, the ground circuit to thepassenger’s window becomes open. As a result, even if Open/Close operation of the passenger’s window is attempted, thecurrent from TERMINAL E of the power window master SW is not grounded and the motor does not rotate, so thepassenger’s window can not be operated and window lock occurs.

The current always flows to TERMINAL 14 of the door lock control relay through the D/L fuse.

1. Manual Lock OperationWhen the door lock control SW or door key lock and unlock SW are operated to LOCK position, a lock signal is input toTERMINAL 7 or 9 of the door lock control relay and causes the door lock control relay to function. The current flows fromTERMINAL 14 of the door lock control relay to TERMINAL 1 to the door lock motors to TERMINALS 2 and 13 of the doorlock control relay to TERMINAL 25 to GROUND and the door lock motors locks the door.

2. Manual Unlock OperationWhen the door lock control SW or door key lock and unlock SW are operated to UNLOCK position, an unlock signal is inputto TERMINAL 8, 10 or 11 of the door lock control relay and causes the door lock control relay to function. The current flowsfrom TERMINAL 14 of the door lock control relay to TERMINALS 2 and 13 to the door lock motors to TERMINAL 1 of thedoor lock control relay to TERMINAL 25 to GROUND and the door lock motors unlocks the door.

3. Double Operation Unlock OperationWhen the door key lock and unlock SW front LH is turned to the unlock side, only the driver’s door is unlocked. By turningthe door key lock and unlock SW front LH to the unlock side, a signal is input to TERMINAL 10 of the door lock control relay,and if the signal is input again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL 13of the door lock control relay to the door lock motors to TERMINAL 1 of the door lock control relay to TERMINAL 25 toGROUND, causing all the other doors are unlocked.

Previous automatic transaxle have selected each gear shift using the mechanically controlled throttle hydraulic pressure,governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, electricallycontrols the line pressure and lock–up pressure etc., through the solenoid valve. Engine control module controls eachsolenoid valve based on the input signals from each sensor, which makes smooth driving possible by shift selection for eachgear that is most appropriate to the driving conditions at that time.

1. Gear Shift OperationDuring driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions,based on input signals from the engine coolant temp. sensor to TERMINAL THW of the engine control module, and also theinput signals to TERMINAL NT+ of the engine control module from the turbine speed sensor devoted to the direct clutch.Current is then output to the electronically controlled transmission solenoid. When shifting to 1st gear, current flows fromTERMINAL S1 of the engine control module to TERMINAL 5 of the electronically controlled transmission solenoid toGROUND, and from TERMINAL S2 of the engine control module to TERMINAL 10 of the electronically controlledtransmission solenoid to GROUND, and continuity to solenoids No.1 and No.2 causes the shift.For the 2nd gear, current flows from TERMINAL S1 of the engine control module to TERMINAL 5 of the electronicallycontrolled transmission solenoid to GROUND, and continuity to the solenoid No.1 causes the shift.For the 3rd gear, there is no continuity to either No.1 or No.2 solenoid.Shifting into 4th gear (Overdrive) takes place when current flows from TERMINAL S2 of the engine control module toTERMINAL 10 of the electronically controlled transmission solenoid to GROUND, and continuity to the solenoid No.2 causesthe shift.

2. Lock–Up OperationWhen the engine control module judges from each signal that lock–up operation conditions have been met, current flowsfrom TERMINAL SL of the engine control module to TERMINAL 4 of the electronically controlled transmission solenoid toGROUND, causing continuity to the lock–up solenoid and causing lock–up operation.

3. Clutch Pressure ControlThe electronically controlled transmission solenoid is controlled by the current from TERMINAL SL of the engine controlmodule, and controls the accumulator hydraulic pressure.As a result, the clutch to hydraulic pressure is adjusted precisely, and allows stable shift change.

4. Line Pressure ControlThe electronically controlled transmission solenoid is controlled by the current from TERMINAL SLT+ of the engine controlmodule, and controls the throttle hydraulic pressure.As a result, the line pressure can be controlled precisely, and the to hydraulic pressure is adjusted according to the shiftchange condition, and allows smooth shift change.

5. Shifting Control in Uphill/Downhill TravelingThis system determines whether the vehicle is traveling on an incline or decline from the throttle opening angle, vehicleacceleration condition and brake pedal operation, and controls the shift up to O/D to allow smooth driving.

6. Clutch to Clutch ControlWhen shifting from the 3rd gear to the 4th gear, the current from the engine control module TERMINAL ST controls theelectronically controlled transmission solenoid, to control the drain orifice hydraulic pressure (Switch orifice). Theelectronically controlled transmission solenoid is also controlled by the current from the engine control module TERMINALSLT+, to adjust the hydraulic pressure precisely, which ensures smooth shifting.

7. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on) when driving in lock–up condition, a signal is input to TERMINAL STP ofthe engine control module, the engine control module operates and continuity to the lock–up solenoid is cut.

8. Overdrive Circuit∗ Overdrive on

When the engine is turned on from ignition off, the engine control module turns the O/D on. When the O/D main SW ispushed while the O/D is off, a signal is input into TERMINAL ODMS of the engine control module, and the O/D is turnedon by the engine control module. In this case, the engine control module controls the gear shift according to the vehicle’sdriving condition, using the O/D range. At this time, the O/D off indicator light is off.

∗ Overdrive offWhen the O/D main SW is pushed while the O/D is on, a signal is input into TERMINAL ODMS of the engine controlmodule, and the O/D is turned off. At this time, the current flows through the O/D off indicator light to TERMINAL ODLP ofthe engine control module. As a result, the O/D off indicator light turns on, and the engine control module controls the gearshift according to the vehicle’s driving condition, without using the O/D range.

1. ABS OperationIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the fourwheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedalis depressed suddenly, the skid control actuator with ECU controls the solenoids in the actuators using the signals from thesensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If theskid control actuator with ECU detects that the fluid pressure in the wheel cylinder is insufficient, the skid control actuatorwith ECU controls the solenoids in the actuators to increase the braking pressure.

2. Traction Control OperationThe traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of thewheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stabilitycorresponding to the road conditions.

3. VSC OperationUnexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under– orover–steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes toreduce the under– or over–steering.To reduce large over–steering :If the VSC system determines that the over–steering is large, it activates the brakes for the outer turning wheels dependingon the degree of the over–steering to produce the moment toward the outside of the vehicle and reduce the over–steering.To reduce large under–steering :If the VSC system determines that the under–steering is large, it controls the engine power and activates the rear wheelbrakes to reduce the under–steering.TRAC OFF SWThe traction control SW is used to stop the TRAC function. After the engine is started, the TRAC system is stopped (Turnedoff) and the TRAC OFF indicator light lights up. When the TRAC OFF SW is pressed again, the TRAC system enters thestand–by mode. If the engine is stopped and restarted, the TRAC system enters the stand–by mode regardless of thetraction control SW.VSC system cannot cut off by using TRAC OFF SW.

4. Mutual System ControlTo efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlledwhile the VSC system is being operated.Engine throttle controlThe engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing theengine output.Engine control and electronically controlled transmission controlThe strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. andreducing changes in the driving torque at shift–down.VSC system operation indicationThe Slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, whilethe VSC system is being operated.

5. Fail Safe FunctionIf an error occurs in the skid control actuator with ECU, sensor signals, and/or actuators, the skid control actuator with ECUinhibits the brake actuator control and inputs the error signal to the engine control module. According to the error signal, thebrake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open requestfrom the VSC system. As a result, the vehicle functions regardless of the ABS, TRAC, and VSC systems.

ABS without VSC

This system controls the respective brake fluid pressures acting on the brake cylinders of the right front wheel, left frontwheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.This results in improved directional stability and steerability during panic braking.

1. Input Signal(1) Speed sensor signal

The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the skid control actuator withECU.

(2) Stop light SW signalA signal is input to TERMINAL STP of the skid control actuator with ECU when the brake pedal is depressed.

2. System OperationDuring sudden braking, the skid control actuator with ECU which has signals input from each sensor lets the hydraulicpressure acting on each wheel cylinder escape to the reservoir.The pump inside the skid control actuator with ECU is also operating at this time and it returns the brake fluid from thereservoir to the master cylinder, thus preventing locking of vehicle wheels.If the skid control actuator with ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the currentacting on the solenoid is controlled and the hydraulic pressure is increased.Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressurereduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

SRS

NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and thenegative (–) terminal cable is disconnected from the battery.(The SRS is equipped with a back–up power source so that if work is started within 90 seconds fromdisconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)

When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back–up power supply from outside the vehicle.

Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.

Do not expose the following parts directly to hot air or flame;

Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;

Never use SRS parts from another vehicle. When replacing parts, replace with new parts.

For the purpose of reuse, never disassemble and repair the following parts.

If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.

Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.

After work on the SRS is completed, check the SRS warning light.

If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.When the ignition SW is turned to ON, the current from the ignition SW flows to TERMINAL (C) 5 of the airbag sensorassembly.If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the ignition SW flows toTERMINALS (C) 14, (C) 16, (C) 10, (C) 8, (A) 8 (w/ side airbag) or (B) 2 (w/o side airbag) and (D) 9 (w/ side airbag) or (E) 5(w/o side airbag) of the airbag sensor assembly to the airbag squibs and the pretensioners to TERMINALS (C) 13, (C) 17,(C) 11, (C) 7, (A) 7 (w/ side airbag) or (B) 1 (w/o side airbag) and (D) 10 (w/ side airbag) or (E) 6 (w/o side airbag) of theairbag sensor assembly to TERMINAL (C) 27, (C) 28 or BODY GROUND to GROUND, so that current flows to the airbagsquibs and the pretensioners and causes them to operate.When the side impact also exceeds a set level, the current from the ignition SW flows to TERMINALS (A) 12, (D) 5, (A) 9 and(D) 8 of the airbag sensor assembly to the side airbag squibs and the curtain shield airbag squibs TERMINALS (A) 11, (D) 6,(A) 10 and (D) 7 of the airbag sensor assembly to TERMINAL (C) 27, (C) 28 or BODY GROUND to GROUND, causing sideairbag squibs and curtain shield airbag squibs to operate.The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to the frontpassenger.Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.The curtain shield airbag can ease an impact on the head of the front and rear passengers and reduce risks of injury.The pretensioners make sure of the seat belt restrainability.

This system utilizes an engine control module and maintains overall control of the engine, transmission and so on. An outlineof the engine control is explained here.

1. Input Signals(1) Engine coolant temp. signal circuit

The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance whichvaries according to the engine coolant temp. thus the engine coolant temp. is input in the form of a control signal intoTERMINAL THW of the engine control module.

(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal into TERMINAL THA of the engine control module.

(3) Oxygen sensor signal circuitThe oxygen density in the exhaust gases is detected and input as a control signal into TERMINALS OX1A and OX1B ofthe engine control module.

(4) RPM signal circuitCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.Camshaft position is input as a control signal to TERMINAL G2+ of the engine control module, and engine RPM is inputinto TERMINAL NE+.

(5) Throttle signal circuitThe throttle position sensor detects the throttle valve opening angle, which is input as a control signal into TERMINALVTA1 of the engine control module.

(6) Vehicle speed signal circuitThe vehicle speed sensor detects the vehicle speed, and the signal is input into TERMINAL SPD of the engine controlmodule via the combination meter, from TERMINAL SP1 of the skid control actuator with ECU.

(7) NSW signal circuit (A/T)The Park/Neutral position SW detects whether the shift position are in neutral, parking or not, and inputs a control signalinto TERMINAL NSW of the engine control module.

(8) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, thevoltage for engine control module start–up power supply is applied to TERMINAL +B of the engine control module viaEFI relay.

(9) Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor during cranking is detected and thesignal is input into TERMINAL STA of the engine control module as a control signal.

Engine Control

2. Control System∗ SFI system

The SFI system monitors the engine condition through the signals, which are input from each sensor to the enginecontrol module. The best fuel injection volume is decided based on this data and the program memorized by the enginecontrol module, and the control signal is output to TERMINALS #10, #20, #30 and #40 of the engine control module tooperate the injector. (Inject the fuel). The SFI system produces control of fuel injection operation by the engine controlmodule in response to the driving conditions.

∗ ESA systemThe ESA system monitors the engine condition through the signals, which are input to the engine control module fromeach sensor. The best ignition timing is detected according to this data and the memorized data in the engine controlmodule, and the control signal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4. This signal controls the ignition coiland igniter to provide the best ignition timing for the driving conditions.

∗ IAC systemThe IAC system increases the RPM and provides idling stability for fast idle–up when the engine is cold and when theidle speed has dropped due to electrical load, etc. The engine control module evaluates the signals from each sensor,outputs current to TERMINAL RSD, and controls the idle air control valve.

∗ Fuel pump control systemThe engine control module operation outputs to TERMINAL FC and controls the C/OPN relay. Thus controls the fuelpump drive speed in response to conditions.

3. Diagnosis SystemWith the diagnosis system, when there is a malfunctioning in the engine control module signal system, the malfunctionsystem is recorded in the memory. The malfunctioning system can then be found by reading the display (Code) of themalfunction indicator lamp.

4. Fail–Safe SystemWhen a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control basedon the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded inthe engine control module memory or else stops the engine.

The current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned to ON position, the current from the GAUGE fuse flows to TERMINAL 5 of the shift lockcontrol SW.

Shift Lock MechanismWith the ignition SW at ON position, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that theshift lever is put in P position (Continuity P SW) is input to the shift lock control SW, the shift lock control SW operates andthe current flows from TERMINAL 5 of the shift lock control SW to TERMINAL SLS+ to the shift lock solenoid to TERMINALSLS– of the shift lock control SW to TERMINAL 1 to GROUND. This causes the shift lock solenoid to turn on (Plate stopperdisengages) and the shift lever can shift into position other than P position.

Current is always applied from the DOME fuse to TERMINAL (A) 7 of the combination meter. When the ignition SW is turnedto ON position, the current from the GAUGE fuse flows to TERMINAL (A) 1 of the combination meter.

1. Seat Belt Warning SystemWhen the ignition SW turned on, a signal is input to the combination meter. To determine whether the driver has fastened theseat belt, a signal is input from the buckle SW LH to TERMINAL (B) 6 of the combination meter. When the seat belt is notfastened, the seat belt warning light in the combination meter blinks, and emits a warning sound.In addition, the front passenger is recognized by a sensor (Occupant detection sensor) is installed in the front passengerseat, and determines whether the seat belt is fastened. When not fastened, the signals from the buckle SW RH is input toTERMINAL (B) 8 of the combination meter, and the front passenger seat belt warning light blinks.

2. Key Reminder SystemWhen the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SWon), a signal is input from the unlock warning SW to TERMINAL (B) 18 of the combination meter, and from the door courtesySW front LH to TERMINAL (B) 25 of the combination meter. As a result, the buzzer in the combination meter goes on andwarns the driver that the key is remaining in the key cylinder.

The current is applied at all times through the RDI fuse to TERMINAL 3 of the FAN NO.1 relay.When the ignition SW is turned on, the current flows through the ECU–IG fuse to FAN NO.1 relay (Coil side) to TERMINAL 6of the engine control module. At the same time as this current flow, the current from ECU–IG fuse flows to the FAN NO.2relay (Coil side) to TERMINAL 7 of the engine control module.

1. Low Speed OperationWhen the A/C system is operating, the FAN NO.1 Relay is turned on. As a result, the current flows from the RDI fuse to FANNO.1 relay (Point side) to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay toTERMINAL 4 to TERMINAL 2 of the A/C condenser fan resistor to TERMINAL 1 to GROUND, and the radiator fan motorrotates at low speed.

2. High Speed OperationWhen the engine control module operated, the FAN NO.1 and NO.2 relay is turned on. As a result, the current flows from theRDI fuse to FAN NO.1 relay (Point side) to radiator fan motor to TERMINAL 3 of the FAN NO.2 Relay to TERMINAL 5 toGROUND, and the radiator fan motor rotates at high speed.

SCION xA (EM00D0U)

Air Conditioning

Current is applied at all times through the HTR fuse to TERMINAL 5 of the HTR relay.When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 1 of the HTR relay toTERMINAL 2 to TERMINAL 6 of the blower SW.

Blower Motor Operation∗ Low speed operation

When the blower SW is moved to LO position, the current flows to TERMINAL 2 of the blower SW to TERMINAL 1 toGROUND, causing the HTR relay to turn on. This causes the current flows from the HTR fuse to TERMINAL 5 of theHTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 1 of the blower resistor toTERMINAL 4 to GROUND, rotating the blower motor at low speed.

∗ Medium speed operation (Operation at M1, M2)When the blower SW is moved to M1 position, the current flows to TERMINAL 2 of the blower SW to TERMINAL 1 toGROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of theHTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 1 of the blower resistor toTERMINAL 2 to TERMINAL 7 of the blower SW to TERMINAL 5 to GROUND. At this time, the blower resistance of theblower resistor is smaller than at low speed, so the blower motor rotates at medium low speed.When the blower SW is moved to M2 position, the current flows through the HTR relay to TERMINAL 1 of the blowermotor to TERMINAL 2 to TERMINAL 1 of the blower resistor to TERMINAL 3 to TERMINAL 6 of the blower SW toTERMINAL 1 to GROUND. At this time, resistance of the blower resistor is smaller than at M1 position, so the blowermotor rotates at medium high speed.

∗ High speed operationWhen the blower SW is moved to HI position, the current flows to TERMINAL 2 of the blower SW to TERMINAL 1 toGROUND, causing the HTR relay to turn on.This causes the current flows from the HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 1 ofthe blower motor to TERMINAL 2 to TERMINAL 10 of the blower SW to TERMINAL 1 to GROUND, rotating the blowermotor at high speed.
