HOW TO USE THIS MANUAL B 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. (All circuit diagrams are shown with the switches in the OFF position.) When 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. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing 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. Wiring related to each system is indicated in each system circuit by arrows (from__, to__). When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL [O]

SYSTEM OUTLINE 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 flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. STOP LIGHT DISCONNECTION WARNING When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection 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 lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off.

[P]

SERVICE HINTS S6 STOP LIGHT SW 2–1 : Closed with the brake pedal depressed L4 LIGHT FAILURE SENSOR 1, 2, 7–GROUND : Approx. 12 volts with the stop light SW on 4, 8–GROUND : Approx. 12 volts with the ignition SW at ON position 11–GROUND : Always continuity

E GLOSSARY OF TERMS AND SYMBOLS GROUND The point at which wiring attaches to the Body, thereby providing a return path for an electrical circuit; without a ground, current cannot flow.

BATTERY Stores chemical energy and converts it into electrical energy. Provides DC current for the auto’s various electrical circuits. CAPACITOR (Condenser) A small holding unit for temporary storage of electrical voltage.

CIGARETTE LIGHTER An electric resistance heating element.

HEADLIGHTS Current flow causes a headlight 1. SINGLE filament to heat up and emit light. A FILAMENT headlight may have either a single (1) filament or a double (2) filament

2. DOUBLE FILAMENT

CIRCUIT BREAKER Basically a reusable fuse, a circuit breaker will heat and open if too much current flows through it. Some units automatically reset when cool, others must be manually reset.

HORN An electric device which sounds a loud audible signal.

DIODE A semiconductor which allows current flow in only one direction.

IGNITION COIL Converts low–voltage DC current into high–voltage ignition current for firing the spark plugs.

DIODE, ZENER

LIGHT Current flow through a filament causes the filament to heat up and emit light.

A diode which allows current flow in one direction but blocks reverse flow only up to a specific voltage. Above that potential, it passes the excess voltage. This acts as a simple voltage regulator.

PHOTODIODE The photodiode is a semiconductor which controls the current flow according to the amount of light.

LED (LIGHT EMITTING DIODE) Upon current flow, these diodes emit light without producing the heat of a comparable light.

DISTRIBUTOR, IIA Channels high–voltage current from the ignition coil to the individual spark plugs.

METER, ANALOG Current flow activates a magnetic coil which causes a needle to move, thereby providing a relative display against a background calibration.

FUSE

METER, DIGITAL Current flow activates one or many LED’s, LCD’s, or fluorescent displays, which provide a relative or digital display.

A thin metal strip which burns through when too much current flows through it, thereby stopping current flow and protecting a circuit from damage.

FUEL

FUSIBLE LINK (for Medium Current Fuse)

(for High Current Fuse or Fusible Link)

A heavy–gauge wire placed in high amperage circuits which burns through on overloads, thereby protecting the circuit. The numbers indicate the crosssection surface area of the wires.

M


MOTOR A power unit which converts electrical energy into mechanical energy, especially rotary motion.

E RELAY Basically, an electrically operated 1. NORMALLY switch which may be normally CLOSED closed (1) or open (2). Current flow through a small coil creates a magnetic field which either opens or closes an attached switch.

SPEAKER An electromechanical device which creates sound waves from current flow.

2. NORMALLY OPEN

SWITCH, MANUAL 1. NORMALLY OPEN

RELAY, DOUBLE THROW A relay which passes current through one set of contacts or the other.

Opens and closes circuits, i it thereby th b stopping (1) or allowing (2) current flow.

2. NORMALLY CLOSED

RESISTOR An electrical component with a fixed resistance, placed in a circuit to reduce voltage to a specific value.

SWITCH, DOUBLE THROW A switch which continuously passes current through one set of contacts or the other.

RESISTOR, TAPPED A resistor which supplies two or more different non adjustable resistance values.

SWITCH, IGNITION A key operated switch with several positions which allows various circuits, particularly the primary ignition circuit, to become operational.

RESISTOR, VARIABLE or RHEOSTAT A controllable resistor with a variable rate of resistance. Also called a potentiometer or rheostat. SENSOR (Thermistor) A resistor which varies its resistance with temperature.

SWITCH, WIPER PARK Automatically returns wipers to the stop position when the wiper switch is turned off.

SENSOR, SPEED Uses magnetic impulses to open and close a switch to create a signal for activation of other components.

TRANSISTOR A solidstate device typically used as an electronic relay; stops or passes current depending on the voltage applied at ”base”.

(Reed Switch Type)

SHORT PIN Used to provide an unbroken connection within a junction block.

SOLENOID An electromagnetic coil which forms a magnetic field when current flows, to move a plunger, etc.


WIRES Wires are always drawn as (1) NOT straight lines on wiring CONNECTED diagrams. Crossed wires (1) without a black dot at the junction are j nott joined; j i d crossed wires (2) with a black dot or octagonal ( ) (2) SPLICED mark at the junction are spliced (joined) connections.

TOYOTA HYBRID SYSTEM SYSTEM OUTLINE FEATURES OF TOYOTA HYBRID SYSTEM This system controls the following modes in order to achieve the most efficient operations to match the driving conditions. (1) Supply of electrical power from the HV battery to motor generator no.2 provides force to drive the wheels. (2) While the tires are driven by the engine via the planetary gears, motor generator no.1 is driven via the planetary gears to supply electricity to motor generator no.2 to drive the wheels. (3) When the vehicle is decelerating, kinetic energy from the wheels is recovered and converted into electrical energy and used to recharge the HV battery by means of motor generator no.2. The hybrid vehicle control ECU switches between these modes (1, 2, 1+2, or 3) according to the driving conditions. However, when the state of charge of the HV battery is low, the HV battery is charged by the engine by turning motor generator no.1. CRUISE CONTROL OPERATION Cruise control is the speed control device, which sets the desired speed by just operating the switch on the control panel without pressing the accelerator pedal. This device is used when you would like to drive the vehicle at the fixed speed. 1. SET CONTROL If you operate the SET/COAST switch when driving (The available range of set speed: between about 40 and 200 km/h) with the main switch is ON (When power indicator comes on), the device memorizes vehicle’s speed when switch is off and controls the fixed speed. 2. SET SPEED CONTROL This device compares the vehicle’s running speed and the memorized speed, and controls the driving power of the motor and the engine by calculating the cruise control requirements so that both speed become equivalent. 3. COAST CONTROL If the SET/COAST switch is continued to be ON during the running with the cruise control, the device recognizes the cruise control requirement is at 0 and decelerates the vehicle’s speed. Then the device memorizes the speed when the switch is off in order to control the fixed speed. In each time you operate SET/COAST switch momentarily (For about 0.5 second), the memorized speed is decreased in about 1.5 km/h. However, in case of the tap–down operation with more than 5–km/h gap between the memorized speed and vehicle’s running speed, the device memorizes the vehicle’s speed when the switch is off and controls the fixed speed. 4. ACCEL CONTROL If the RESUME/ACCEL switch is continued to be ON during the running with the cruise control, the device recognizes the cruise control is on the acceleration side and accelerates the vehicle’s speed. Then the running speed when the switch is off is memorized to control the fixed speed. In each time you operate RESUME/ACCEL switch momentarily (For about 0.5 second), the memorized speed is increased in about 1.5 km/h. However, if there is more than 5–km/h gap between the memorized speed and vehicle’s running speed, this operation does not change the memorized speed. (Tap–up operation is not available.) 5. RESUME CONTROL If the running speed is faster than the low speed limit after the cruise control is canceled manually, the fixed speed is controlled by the OFF–ON operation of RESUME/ACCEL switch, so that the vehicle’s speed returns to the memorized speed at the time the cruise control is released.


6. MANUAL CANCEL CONTROL When each of the following signals is input during driving with cruise control, the cruise control is released with turning the cruise control requirement to 0. (The memorized speed is maintained when following signals except the signal, main switch OFF is input.) ∗ Stop light switch ON (Pressing the brake pedal) ∗ Control switch’s cancel switch ON ∗ Main switch OFF 7. AUTO CANCEL FUNCTION A) The memorized speed is erased and the control is canceled if the following conditions occur. The power indicator blinks at that time until the main switch is turned ON. The speed control is unavailable unless the main switch is turned ON again. ∗ When the stop light switch breaks or short–circuits. ∗ When sudden change of the running speed signal occur. B) The memorized speed is erased and the control is canceled if the following conditions occur. ∗ When the malfunction of the stop light switch input circuit occurs. ∗ When the running speed becomes slower than 40km/h. ∗ When the running speed becomes slower than the speed that 16 km/h subtracted from the memorized speed. 8. REGENERATIVE SYSTEM OPERATION This system operates the motor as a generator to change the kinetic energy of the vehicle into the electricity when accel pedal release or foot braking controls the vehicle, and store the electricity in the battery.

ENGINE CONTROL SYSTEM OUTLINE This system utilizes an engine control module and maintains overall control of the engine, transmission and so on. An outline of 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 which varies according to the engine coolant temp. thus the engine coolant temp. is input in the form of a control signal into TERMINAL THW of the engine control module. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a control signal into TERMINAL THA of the engine control module. (3) Oxygen sensor signal circuit The oxygen density in the exhaust gases is detected and input as a control signal into TERMINALS OX1A and OX1B of the engine control module. (4) RPM signal circuit 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 TERMINAL G2 of the engine control module, and engine RPM is input into TERMINAL NE+. (5) Throttle signal circuit The throttle position sensor detects the throttle valve opening angle, which is input as a control signal into TERMINALS VTA and VTA2 of the engine control module. (6) Vehicle speed signal circuit The vehicle speed signal from combination meter, detects the vehicle speed and inputs a control signal into TERMINAL SPD of the engine control module via the combination meter. (7) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, the voltage for engine control module start–up power supply is applied to TERMINAL +B of the engine control module via EFI relay. (8) Engine knock signal circuit Engine knocking is detected by knock sensor and the signal is input into TERMINAL KNK1 of the engine control module as a control signal. 2. CONTROL SYSTEM ∗ SFI system The SFI system monitors the engine condition through the signals, which are input from each sensor to the engine control module. The best fuel injection volume is decided based on this data and the program memorized by the engine control module, and the control signal is output to TERMINALS #10, #20, #30 and #40 of the engine control module to operate the injector. (Inject the fuel). The SFI system produces control of fuel injection operation by the engine control module in response to the driving conditions. ∗ ESA system The ESA system monitors the engine condition through the signals, which are input to the engine control module from each sensor. The best ignition timing is detected according to this data and the memorized data in the engine control module, and the control signal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4. This signal controls the ignition coil and igniter to provide the best ignition timing for the driving conditions. ∗ Fuel pump control system The engine control module operation outputs to TERMINAL FC and controls the CIR OPN relay. Thus controls the fuel pump drive speed in response to conditions. 3. DIAGNOSIS SYSTEM With the diagnosis system, when there is a malfunctioning in the engine control module signal system, the malfunction system is recorded in the memory. The malfunctioning system can then be found by reading the display (Code) of the malfunction indicator lamp. 4. FAIL–SAFE SYSTEM When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded in the engine control module memory or else stops the engine.

SYSTEM OUTLINE With the ignition SW turned on, the current flows to TERMINAL 15 of the body ECU through GAUGE fuse. Voltage is applied at all times to TERMINAL (A) 11 of the body ECU through the TAIL relay. Coil side, and to TERMINAL (A) 2 through the HEAD relay coil side (w/o daytime running light) or through the daytime running light relay (w/ daytime running light). 1. NORMAL LIGHTING OPERATION With the light control SW turned to TAIL position, a signal is input into TERMINAL (A) 18 of the body ECU. Due to this signal, the current flowing to TERMINAL (A) 11 of the body ECU flows to TERMINAL (A) 18 to TERMINAL 14 of the light control SW to TERMINAL 16 to GROUND, and taillight relay causes taillights to turn on. With the light control SW turned to HEAD position, a signal is input into TERMINALS (A) 17 and (A) 18 of the body ECU. Due to this signal, the current flowing to TERMINAL (A) 2 of the body ECU flows to TERMINAL (A) 17 to TERMINAL 13 of the light control SW to TERMINAL 16 to GROUND in the headlight circuit, and causes taillight and HEAD relay to turn the lights on. The taillight circuit is same as above. 2. LIGHT AUTO TURN OFF OPERATION With light on and ignition SW turned off (Input signal goes to TERMINAL 15 of the body ECU), when the driver’s door is opened (Input signal goes to TERMINAL 3 of the body ECU), the ECU operates and the current is cut off which flows from TERMINAL (A) 11 of the body ECU to TERMINAL (A) 18 in taillight circuit and from TERMINAL (A) 2 to TERMINAL (A) 17 in headlight circuit. As a result, all lights are turned off automatically.

SYSTEM OUTLINE When the ignition SW is turned ON, the current flows from WIPER fuse to wiper and washer SW TERMINAL 17 and front wiper motor TERMINAL 2 or the current flows from WASHER fuse to washer motor TERMINAL 2. 1. LO POSITION When the wiper and washer SW is at LO position, the current flows from wiper and washer SW TERMINAL 17 to TERMINAL 7 to front wiper motor TERMINAL 5 to TERMINAL 4 to GROUND, and the front wiper motor runs at low speed. 2. HI POSITION When the wiper and washer SW is at HI position, the current flows from wiper and washer SW TERMINAL 17 to TERMINAL 8 to front wiper motor TERMINAL 3 to TERMINAL 4 to GROUND, and the front wiper motor runs at high speed. 3. INT POSITION When the wiper and washer SW is at INT position, the wiper relay is activated and the current flows from wiper and washer SW TERMINAL 17 to TERMINAL 2 to GROUND. This current activates the intermittent circuit, and the current flows from wiper and washer SW TERMINAL 17 to TERMINAL 7 to front wiper motor TERMINAL 5 to TERMINAL 4 to GROUND, and operates the front wipers. 4. WASHER CONTINUOUS OPERATION When the wiper and washer SW is pulled to WASHER position (Washer SW ON position), the current from the WASHER fuse flows to washer motor TERMINAL 2 to TERMINAL 1 to wiper and washer SW TERMINAL 11 to TERMINAL 2 to GROUND, and operates the washer motor to emit a water spray. At the same time, the current flows from the WIP fuse to wiper and washer SW TERMINAL 17 to TERMINAL 7 to front wiper motor TERMINAL 5 to TERMINAL 4 to GROUND, and operates the front wiper motor.

POWER WINDOW SYSTEM OUTLINE Communication between power window master SW and body ECU is controlled and body ECU recognizes the conditions of each SW to control the operation of windows. 1. MANUAL UP OR DOWN OPERATION (DRIVER’S WINDOW, PASSENGER’S WINDOW) During you are pushing power window master SW (Driver side) halfway down, the motor operates and the window on the driver’s side opens. During you are pulling power window master SW (Driver side) halfway up, the motor operates and the windows on the driver’s side closes. The window on the passenger’s side opens or closes by pushing down or pulling up power window master SW (Front passenger, rear passenger) or power window SW front RH, rear LH, RH. 2. AUTO UP OR DOWN OPERATION (DRIVER’S WINDOW) When the power window master SW (Driver side) is fully pushed down, the motor operates and the window on the driver’s side automatically opens. When the power window master SW (Driver side) is fully pulled up, the motor operates and the window on the driver’s side automatically closes. 3. STOPPING AUTOMATIC WINDOW OPERATION If you push the power window master SW (Driver side) halfway down during the window on the driver’s side is raising automatically, the motor’s operation stops. And if you pull the power window master SW (Driver side) halfway up during the window on the driver’s side is lowering automatically, the motor’s operation stops. 4. KEY OFF POWER WINDOW OPERATION After the Ignition SW is turned off, the windows can be operated for about 43 seconds. However, the window operation stops when either front doors opens. 5. JAM PROTECTION FUNCTION (DRIVER’S WINDOW) When any foreign object gets caught during power window UP operation, the motor rotates in the opposite direction to open the window.

SYSTEM OUTLINE When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 1 of the shift lock ECU, in the ON position, the current from the ECU–IG fuse flows to TERMINAL 3 of the ECU. 1. SHIFT LOCK MECHANISM With the ignition SW on, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that the shift lever is put in P position (Continuity between P1 and P of the shift lock control SW) is input to the ECU, the ECU operates and current flows from TERMINAL 3 of the ECU to TERMINAL SLS+ of the shift lock solenoid to solenoid to TERMINAL SLS– to TERMINAL 5 of the ECU to GROUND. This causes the shift lock solenoid to turn on (Plate stopper disengages) and the shift lever can shift into position other than the P. 2. KEY INTERLOCK MECHANISM With the ignition SW ON or ACC position, when the shift lever is put in P position (No continuity between P2 and P of shift lock control SW), the current flowing from TERMINAL 4 of the ECU to the key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock lever disengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

DOOR LOCK CONTROL SYSTEM OUTLINE The current is always sent from DOOR fuse to TERMINAL B of body ECU. When ignition SW is turned on, the current is sent from GAUGE fuse to TERMINAL IG of the body ECU. 1. MANUAL LOCK OPERATION When the door lock control SW (Power window master SW) is turned to LOCK position, the lock signal from TERMINAL MPX1 of power window master SW is input to TERMINAL RX of body ECU to operate ECU. The current is sent from TERMINAL ACT+ of ECU to each motor and the motor locks the doors by the current sent from TERMINAL ACT– of ECU to GROUND. 2. MANUAL UNLOCK OPERATION When the door lock control SW (Power window master SW) is turned to UNLOCK position, the unlock signal from TERMINAL MPX1 of power window master SW is input to TERMINAL RX of body ECU to operate ECU. The current is sent from TERMINAL ACT– of ECU to each motor and the motor unlocks the doors by the current sent from TERMINAL ACT+ of ECU to GROUND. 3. DOOR KEY LOCK AND UNLOCK OPERATION ∗ Lock operation from the driver’s side door When the driver’s side door is locked using the ignition key, all the doors are locked. ∗ Unlock operation from the driver’s side door When the driver’s side door is unlocked once using the ignition key, only the driver’s side door is unlocked. If this operation is repeated within 3 seconds, all the other doors are unlocked. ∗ Lock operation from the front passenger’s side door When the front passenger’s side door is locked using the ignition key, all the doors are locked. ∗ Unlock operation from the front passenger’s side door When the front passenger’s side door is unlocked using the ignition key, all the doors are unlocked SERVICE HINTS B8 (A), B9 (B) BODY ECU 15–GROUND : Approx. 12 volts with the ignition SW at ON position 8–GROUND : Always approx. 12 volts (B) 1–GROUND : Always continuity D6, D7, D8, D9 DOOR COURTESY SW FRONT LH, RH, REAR LH, RH 1–GROUND : Closed with each of the door open U1 UNLOCK WARNING SW 1–2 : Closed with the ignition key in the cylinder : PARTS LOCATION Code

SRS NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary instructions and the procedure and precautions in the Repair Manual for the applicable model year. Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. Work must be started after 90 seconds from when the ignition switch is turned to the ”LOCK” position and the negative (–) 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 from disconnecting the negative (–) terminal cable of the battery, the SRS may be deployed.) When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each memory system, never use a back–up power supply from outside the vehicle. Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs. Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly or side airbag sensor directly to hot air or flames. Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly and side airbag sensor assembly should be inspected. Never use SRS parts from another vehicle. When replacing parts, replace them with new parts. Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly or side airbag sensor assembly in order to reuse it. If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly or side airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones. Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits. Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices. After work on the SRS is completed, perform the SRS warning light check. If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual.

SRS SYSTEM OUTLINE 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 ACC or ON, current from the SRS ACC fuse flows to TERMINAL (B) 6 of the airbag sensor assembly. Only when the ignition SW is on does the current flow TERMINAL (B) 5 of the airbag sensor assembly. If an accident occurs while driving, when the frontal impact exceeds a set level, current flows to TERMINALS (B) 14, (B) 10, (A) 2 and (C) 5 of the airbag sensor assembly to TERMINAL 1 of the airbag squibs and the pretensioners to TERMINAL 2 to TERMINALS (B) 13, (B) 11, (A) 1 and (C) 6 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, so that current flows to the front airbag squibs and the pretensioners and causes them to operate. When the side impact also exceeds a set level, current from the ignition SW (IG2) or SRS ACC fuse flows to TERMINALS (A) 5, (C) 2, (A) 2 and (C) 5 of the airbag sensor assembly to TERMINAL 1 of the side airbag squibs and the pretensioners to TERMINAL 2 to TERMINALS (A) 6, (C) 1, (A) 1 and (C) 6 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, causing side airbag squibs and the pretensioners 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 front passenger. Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger (w/ side airbags). The pretensioners make sure of the seat belt restrainability. : PARTS LOCATION Code A17

SYSTEM OUTLINE 1. INPUT SIGNALS (1) Speed sensor signal The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the brake ECU. (2) Stop light SW signal A signal is input to TERMINAL STP of the brake ECU when the brake pedal is depressed. 2. ABS SYSTEM OPERATION During sudden braking the brake ECU has signals input from each sensor, which controls the current to the solenoid inside the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. The pump 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 brake ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current on the solenoid is controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled by the brake ECU, by the same method as above. Pressure reduction, holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.
