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.)

om

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.

ww w

.E

CU

11

8.c

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 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 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 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 lamp 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.

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.

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

CIGARETTE LIGHTER An electric resistance heating element.

DIODE, ZENER

CU

11

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

HORN An electric device which sounds a loud audible signal.

8.c

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.

om

2. DOUBLE FILAMENT

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

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

.E

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.

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.

ww w

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

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)

http://telegram.me/Ecu118 MOTOR A power unit which converts energy into mechanical www.Ecu118.com electrical energy, especially rotary motion. @ecu118

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

YARIS (EM01V0U)


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

RELAY Basically, an electrically operated 1. NORMALLYswitch 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. 2. NORMALLY OPEN

SWITCH, MANUAL Opens and closes circuits, thereby 1. NORMALLY stopping (1) or OPEN allowing (2) current flow.

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

2. NORMALLY CLOSED

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

8.c 11

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

om

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

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

.E

CU

RESISTOR, VARIABLE or RHEOSTAT A controllable resistor with a variable rate of resistance. Also called a potentiometer or rheostat.

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”.

ww w

SENSOR (Thermistor) A resistor which varies its resistance with temperature.

(Reed Switch Type)

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

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 not joined; crossed wires (2) with a black dot or octagonal ( ) (2) SPLICED mark at the junction are spliced (joined) connections.


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