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.

AVALON (EM00A0U)
B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop lamp 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 lamp 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.

E GLOSSARY OF TERMS AND SYMBOLS
BATTERYStores chemical energy andconverts it into electrical energy.Provides DC current for the auto’svarious electrical circuits.
GROUNDThe point at which wiring attaches tothe Body, thereby providing a returnpath for an electrical circuit; without aground, current cannot flow.
CAPACITOR (Condenser)A small holding unit for temporarystorage of electrical voltage.
HEADLIGHTSCurrent flow causes a headlightfilament to heat up and emit light. Aheadlight may have either a single(1) filament or a double (2) filament
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.

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.

Engine Control
The engine control system utilizes a microcomputer and maintains overall control of the engine, transaxle etc. An outline ofthe engine control is given 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. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.
(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 to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensorsto TERMINALS OX1B and OX2B of the engine control module.
(4) RPM signal circuitCamshaft position is detected by the crankshaft position sensor No.2 (RH exhaust side, RH intake side and LH exhaustside), crankshaft position sensor No.3 (LH intake side) and their signals are input to TERMINALS EV1+, EV2+, VV1+and VV2+ of the engine control module as control signals. Also, the engine RPM is detected by the crankshaft positionsensor installed in the cylinder block and the signal is input into TERMINAL NE+ of the engine control module as acontrol signal.
(5) Throttle position sensor signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA1 and VTA2 of the engine control module.
(6) Vehicle speed 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 ECU with actuator.
(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. When the power SW is pushed on(Power SW type), or when the ignition SW is turned on (Ignition SW type), the voltage for engine control module start–uppower supply is applied to TERMINAL +B and +B2 of engine control module via EFI relay.
(8) Intake air volume signal circuitThe intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of theengine control module.
(9) Stop lamp SW signal circuitThe stop lamp SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP ofthe engine control module as a control signal.
(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking isdetected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuitEngine knocking is detected by the knock control sensors, and is input into TERMINALS KNK1 and KNK2 of the enginecontrol module as a control signal.
(12)Air fuel ratio signal circuitThe air fuel ratio is detected and input as a control signal into TERMINALS A1A+, A2A+ of the engine control module.

2. Control System∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.The control signal is sent to the engine control module TERMINALS #10, #20, #30, #40, #50 and #60 to operate theinjector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the drivingconditions.
∗ ESA systemThe ESA system monitors the engine condition through the signals input from each sensors to the engine control module.The best ignition timing is decided according to this data and the data memorized in the engine control module. Thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5 and IGT6, and these signals control the igniter toprovide the best ignition timing.
∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine controlmodule evaluates the signals from each sensors, and outputs current to TERMINALS HT1B or HT2B to control the heater.
∗ Air fuel ratio sensor heater control systemThe air fuel ratio sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaustemission is low), and warms up the air fuel ratio sensor to improve detection performance of the sensor.The engine control module evaluates the signals from each sensor, current is output to TERMINALS HA1A and HA2A,controlling the heater.
∗ ACISThe ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed inaccordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in allranges from low to high speeds.
∗ ETCS–iThe ETCS–i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, underall driving conditions.
∗ VVT–iControls the intake camshaft to an optimal valve timing in accordance with the engine condition.
3. Diagnosis SystemWhen there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in thememory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail–Safe SystemWhen a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued controlbased on that system. In that case, the fail–safe system either controls the system using the data (Standard values)recorded in the engine control module memory, or else stops the engine.

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 ECU controls the solenoids in the actuators using the signals from the sensors tomove the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the skid controlECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoids in the actuators toincrease 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.
4. Fail Safe FunctionIf an error occurs in the skid control ECU, sensor signals, and/or actuators, the skid control ECU inhibits the brake actuatorcontrol and inputs the error signal to the engine control module. According to the error signal, the brake actuator turns off thesolenoid and the engine control module rejects any electronically controlled throttle open request from the VSC system. As aresult, the vehicle functions regardless of the ABS, TRAC, and VSC systems.

∗ ABS systemThis system controls the respective brake fluid pressures acting on the disc 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 improveddirectional stability and steerability during panic braking.∗ Front and rear braking force distribution systemUsing the hydraulic controlling device, this system distributes the braking force to the front and rear wheel in appropriatelyaccording to the running condition of the vehicle.
1. Input Signals(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS 5, 7, 10 and 19 of the skid control ECU with actuator.(2) Stop light SW signal
A signal is input to TERMINAL 20 of the skid control ECU with actuator when the brake pedal is depressed.
2. System OperationDuring sudden braking the skid control ECU with actuator has signals input from each sensor, which controls the current tothe solenoid inside the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. Thepump inside the actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder,thus preventing locking of the vehicle wheels.If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the currenton the solenoid is controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled bythe skid control ECU with actuator, by the same method as above. Pressure reduction, holding and increase are repeated tomaintain 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 (Ignition SWtype) or the power SW is pushed to the ”OFF” position (Power SW type) and the negative (–) terminal cable isdisconnected 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 system reaches an ignition judgment to deploy the following device based on the signals received from the frontairbag sensor and deceleration sensor.– Driver Airbag– Front Passenger Airbag– Knee Airbag– Seat Belt Pretensioner
∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the sideairbag sensors.– Side Airbags– Curtain Shield Airbags
∗ The dual–stage SRS airbag system has been used for the driver and front passenger airbags. This system controls theoptimal airbag inflation by judging the extent of impact, seat position (driver seat), whether or not the seat belt is fastened(driver seat) and information from the front passenger occupant classification system.
∗ The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult orchild (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat beltis buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, andfront passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through theuse of the AIRBAG ON/OFF indicator lights.
∗ The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump when theairbag is deployed.
∗ The Airbag sensor assembly transmits a signal to the body ECU in order to release the door lock when the airbag isdeployed.

The radar cruise control system allows you to drive at a selected cruising speed, maintaining an appropriatevehicle–to–vehicle distance using the laser radar sensor, the steering sensor and the yaw rate sensor. The laser radarsensor detects the reflection of the vehicle ahead in your lane.
1. Setting Operation<The vehicle–to–vehicle distance control mode>While the ON–OFF SW is ON (The power indicator light is turned on), bring the vehicle to the desired speed, press thecontrol lever downward in the ”– SET” direction and release it. This sets the vehicle at that speed from the lower limit of thepreset speed about 45 km/h (28 mph) to the upper limit of the preset speed about 135 km/h (85 mph). However, the vehiclespeed is faster than 135 km/h (85 mph), the preset spped is the upper limit of the preset speed.<The conventional cruise control mode>While the ON–OFF SW is ON (The power indicator light is turned on), bring the vehicle to the desired speed, press thecontrol lever downward in the ”– SET” direction and release it. This sets the vehicle at that speed. It is possible to set at thatspeed between lower speed limit and higher speed limit.
2. Resetting to a Speed<The vehicle–to–vehicle distance control mode>(1) Resetting to a lower speed
The set speed can be decreased 5 mph (For USA) or 5 km/h (For Canada) each time by pressing the control leverdownward in the ”– SET” direction quickly within 0.5 seconds.And while the cruise control is on and the control lever is held downward in the ”– SET” direction, the preset speed willdecrease every 5 mph (For USA) or 5 km/h (For Canada). But you cannot decrease lower than the lower limit of thepreset speed about 27 mph (For USA) or 43 km/h (For Canada). If the preset speed is changed, the vehicle speed willbe gradually decreased to the preset speed. (In the other case, perhaps the vehicle speed will be increase.)
(2) Resetting to a faster speed∗ The set speed can be increased 5 mph (For USA) or 5 km/h (For Canada) each time by pressing the control lever
upward in the ”+ RES” direction quickly within 0.5 seconds.And while the cruise control is on and the control lever is held upward in the ”+ RES” direction, the preset speed willincrease every 5 mph (For USA) or 5 km/h (For Canada). But you cannot increase faster than the upper limit of thepreset speed. If the preset speed is changed, the vehicle speed will be constantly increased to the preset speed. (In theother case, perhaps the vehicle speed will be decrease.)
∗ When your vehicle follow up cruise function, if press the control lever upward in the ”+ RES” direction, the vehicle speedwill not be increased and the preset speed will be changed only.
<The conventional cruise control mode>(1) Deceleration
∗ While the cruise control is on and the control lever is held downward in the ”– SET” direction, the vehicle speed willgradually decrease. When you release it, this sets the vehicle speed at that speed. If the control lever is released whenthe vehicle speed exceeds the upper limit of the preset speed traveling downhill while you are pressing the control leverdownward, the system will memorize the upper limit of the preset speed as a preset speed.
∗ When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed canbe decreased 1.6 km/h (1 mph) each time by pressing the control lever downward in the ”– SET” direction quickly within0.5 seconds. But if the control lever is released when the difference between the actual vehicle speed an the set speedis more than 5 km/h (3 mph), this sets the vehicle speed at that speed.
(2) Acceleration∗ While the cruise control is on and the control lever is held upward in the ”+ RES” direction, the vehicle speed will
constantly increase. When you release it, this sets the vehicle speed at that speed. If the vehicle speed exceeds theupper limit of the preset speed while you are pressing the control lever downward, the system will cruise at the upperlimit of the preset speed. And if the control lever is released, this sets the vehicle speed at that speed.
∗ When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed canbe increased 1.6 km/h (1 mph) each time by pressing the control lever upward in the ”+ RES” direction quickly within 0.5seconds. But if the control lever is released when the difference between the actual vehicle speed and the set speed ismore than 5 km/h (3 mph), this sets the vehicle speed at that speed.
∗ If you are pressing the control lever downward and released when the vehicle speed is increased by pressing theacceleration pedal, the system will memorize the preset speed at that speed. But if you operate the control leverdownward at the upper limit of the set speed, you cannot set the preset speed.
3. The Lower Limit of the Preset Speed∗ This is the lower limit of the preset speed of the followings. This is a difference of the lower limit of the canceled speed.
∗ For USA : about 27 mph∗ For Canada : about 43 km/h
∗ When the vehicle speed is less than the lower limit of the preset speed, you cannot change the preset speed.

Dynamic Radar Cruise Control
4. The Lower Limit of the Canceled Speed∗ This is the lower limit of the canceled speed about 40 km/h (25 mph). And if the vehicle speed falls below about 40 km/h
(25 mph), the preset speed will be automatically cancelled. In the vehicle–to–vehicle distance control mode the presetspeed will be stored, and in the conventional cruise control mode the preset speed will not be stored.
5. The Upper Limit of the Preset SpeedThis is the upper limit of the preset speed of the followings.
∗ For USA : about 85 mph∗ For Canada : about 139 km/h
6. The Upper Limit of the Possible Speed to Use the Cruise Control (Only for the Conventional Cruise Control Mode)This is the upper limit of the possible speed to use the cruise control.
∗ For USA : about 125 mph∗ For Canada : about 200 km/h
7. Resuming the Preset Speed∗ If the preset speed has been canceled, when you push the lever up in the ”+ RES” direction while ”RADAR READY”
shows up on the instrument cluster and at a vehicle speed of about more than the lower limit of the canceled speed, thespeed set prior to cancellation will be restored.However, once the vehicle speed falls below about 40 km/h (25 mph), the preset speed will not be resumed at theconventional cruise control mode.
∗ During follow–up cruising, if there are no vehicles running ahead because they have changed lanes, your vehicle willaccelerate gradually up to the preset speed. At this time, pushing the control lever upward in the ”+ RES” direction willquickly speed up your vehicle in the vehicle–to–vehicle distance control mode.
8. Shift Down ControlWhile the cruise control is on, there is a possible case of the cancelled over drive on a climbing hill. If the system judge theend of a climbing hill after the cancelled over drive, the vehicle will return the over drive mode after the returned over drivetimer.
9. Canceling the Preset SpeedIf the following signals is put in the micro computer when the cruise control is on, this system will be cancel. (The presetspeed has been stored.)
A) Depressing the brake pedal. (Input the stop light switch signal)
B) Turn the ”D” position circuit in neutral start switch on and then off.When the transmission is changed from ”D” or ”N”, cancel the preset speed.At transmission ”S”, when the transmission is changed from ”5” or ”4” to ”N”, ”3”, ”2” and ”1”, cancel the preset speed.
C) Pulling the control lever in the ”CANCEL” direction.
D) The ON–OFF SW is OFF. (In this case, the set speed is not stored.)
E) VSC system is activated.

10. Automatically Cancel(1) If any of the following conditions then occurs, the preset speed automatically cancels out and the cruise control system
will be canceled. And then, the ”CRUISE” indicator light in the instrument cluster flashes until the ON–OFF SW will beturned off, the master warning light comes on and the warning tone sounds, and the warning code will appear on thedisplay. The system cannot be entered until the ON–OFF SW will be turned on again.
A) The vehicle speed sensor is malfunction.
B) The parts of the electronic throttle are malfunction.
C) The stop light switch circuits is open or short.(2) If any of the following conditions then occurs, the preset speed automatically cancels out and the cruise control system
will be canceled. And then, the ”CRUISE” indicator light in the instrument cluster flashes until the ON–OFF SW will beturned off, the master warning light comes on and the warning tone sounds, and the warning code will appear on thedisplay. The system cannot be entered until the ON–OFF SW will be turned on again.
A) The laser radar sensor is malfunction.
B) Improper aiming of laser radar sensor beam axis.
C) The radar cruise control system is malfunction except above A), B).(3) If any of the following conditions then occurs, the preset speed automatically cancels out and the cruise control system
will be canceled. And then, the ”CRUISE” indicator light in the instrument cluster flashes until the ON–OFF SW will beturned off, the master warning light comes on and the warning tone sounds, and the warning code will appear on thedisplay. The system cannot be entered until it will be back the normal condition from above A)~E) (It is possible toresume.) and the ON–OFF SW will be turned on again.
A) The laser radar sensor is dirtied.
B) The wipers are operated at high or low speeds (Including high and low speed operations with the wiper lever in the”AUTO” position.)
C) The driving pattern selector switch is set to ”SNOW” mode.
D) Direct the strong light of sunlight, etc. from the front.
E) It is determined that it is difficult to make a measurement because of bad weather (Such as rainy, foggy, or snowyweather).
(4) If any of the following conditions then occurs, the preset speed will be automatically cancelled out.However, at the vehicle–to–vehicle distance control mode the preset speed will be stored.
A) The vehicle speed falls below about 40 km/h (25 mph).
B) The vehicle speed drops 16 km/h (10 mph) below preset speed. (Only for the conventional cruise control mode)
11. Changing the Radar Cruise Control ModeWhen you push the ON–OFF SW, the vehicle–to–vehicle distance mode is activated. To change to the conventional (Fixedspeed) cruise control mode, push the lever in the ”MODE” direction for longer than about 1 second.However, once the vehicle–to–vehicle distance mode activates and is used, it cannot be changed to the conventional cruisecontrol mode using the above operation.To change the mode, turn the ON–OFF SW off and then on. Next push the lever in the ”MODE” direction for longer thanabout 1 second.If the system malfunction then occurs, turn the engine off and then it on again. Next above operation will be changed to it.

Cruise Control
The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valveby the SW, and allows driving at a constant speed without depressing the accelerator pedal.
Set OperationWhen the ON–OFF SW is turned on, the systems starts preparations for cruise control and turns on the indicator light in thecombination meter.
Set Speed ControlWhen the – SET SW is operated with the ON–OFF SW turned on during driving, the speed is controlled at a constant speed.
Coast ControlWhen the – SET SW is kept turned on during cruise control driving, the engine control module controls the throttle valve todecelerate the vehicle speed.Every time the – SET SW is turned on instantaneously, the vehicle speed is decelerated by approx. 1.6 km/h.
Accel ControlWhen the + RES SW is kept turned on during cruise control driving, the engine control module controls the throttle valve toaccelerate the vehicle speed.Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated by approx. 1.6 km/h.
Resume ControlIf the vehicle speed is within the low speed limit (Approx. 40 km/h, 25 mph) when canceling the cruise control, operation ofthe + RES SW accelerates the vehicle speed and resumes the level before canceling the cruise control.
Manual Cancel MechanismIf any one of the following signals is input during cruise control driving, the cruise control is canceled.∗ The stop light SW is on∗ The CANCEL SW is turned on∗ The ON–OFF SW is turned off∗ When switching from ON to OFF of ”D” position circuit in neutral start switch.
When the transmission is shifted from ”D” to ”N”.When the transmission is shifted from 5, 4 to 3, 2, 1 in S mode.
Auto Cancel FunctionIf any of the following conditions are detected, the cruise control is canceled:∗ Failure in the stop light SW wiring∗ Abnormality in the vehicle speed signal∗ Malfunction in the electronically controlled throttle parts∗ When the vehicle speed gets slower than the low speed limit.∗ When the vehicle speed falls to 16 km/h less than the set speed.
Overdrive FunctionThe overdrive may be canceled if the vehicle travels on a upward slope during cruise control driving. When the throttleopening information indicates the hill climbing is finished after the overdrive is canceled, the vehicle returns to overdrivemode again as the overdrive return timer is completed.

1. Line Pressure Optimal ControlThrough the use of the solenoid valve SLT, the line pressure is optimally controlled in accordance with the engine torqueinformation, as well as with the internal operating conditions of the torque converter and the transaxle. Accordingly, the linepressure can be controlled minutely in accordance with the engine output, traveling condition, and the ATF temperature, thusrealizing smooth shift characteristics and optimizing the workload in the oil pump.
2. Clutch Pressure Optimal ControlThe engine control module monitors the signals from various types of sensor such as the input turbine speed sensor,allowing shift solenoid valves SL1, SL2 and SL3 to minutely control the clutch pressure in accordance with engine outputand driving conditions. As a result, smooth shift characteristics have been realized.
3. Shifting Control in Uphill/Downhill TravelingThis control minimizes the shifting of gears when the driver operates the accelerator pedal while driving on a winding roadwith ups and downs, in order to ensure a smooth drive.
4. Flex Lock–Up Clutch ControlThe flex lock–up clutch control operates during acceleration, in the 4th and 5th gear in the D range, and during deceleration,in the 4th and 5th gear in the D range and in the 4th gear in the 4 range.
5. Multi Mode Automatic TransmissionMulti mode automatic transmission have [S]–position is beside of [D]–position. If moving the selector lever ”S” side, you canselect shift range just link manual shifting.

AVALON (EM00A0U)
Cooling Fan
System OperationWhen the power SW is pushed to IG ON position (Power SW type), or when the ignition SW is turned to ON (Ignition SWtype), the current from the HTR fuse is sent to the coil side and the FAN NO.1 relay is turned to ON. Then the current flows toTERMINAL 3 of the cooling fan ECU. At the same time, the conditions of the A/C SW, A/C pressure sensor, engine coolanttemp. sensor and engine rotation are sent to the TERMINAL 2 as signals from front controller. As a result of that, the coolingfan ECU continuously controls the rotation of the fan motor and keeps a balance between the cooling efficiency andsilentness with the optimal fan rotation.
