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 SINGLE FILAMENT filament to heat up and emit light A headlight may have either a single (1) filament or a double (2) filament 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 18 CAMRY Hybrid Vehicle (EM02H0U) E RELAY Basically, an electrically operated 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 NORMALLY OPEN RELAY, DOUBLE THROW A relay which passes current through one set of contacts or the other SPEAKER An electromechanical device which creates sound waves from current flow SWITCH, MANUAL Opens and closes circuits, thereby NORMALLY stopping (1) or OPEN allowing (2) current flow 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 (Reed Switch Type) 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” 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 not joined; crossed wires (2) with a black dot or octagonal ( ) (2) SPLICED mark at the junction are spliced (joined) connections 19 CAMRY Hybrid Vehicle (EM02H0U) I GROUND POINT A73 Skid Control ECU (GND) A74 Skid Control ECU (GND2) A74 Skid Control ECU (GND3) W–B W–B W–B W–B (E) A50 (E) Turn Signal
