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 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.

RAV4 (EM03T0U)

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 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.

VOLTAGE CHECK

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

point.
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 ground

point or negative battery terminal, and the positive lead to the
connector 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 voltage

between the check points.

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

points.

If the circuit has diodes, reverse the two leads and check
again.
When contacting the negative lead to the diode positive side
and the positive lead to the negative side, there should be
continuity.
When contacting the two leads in reverse, there should be no
continuity.

(c) Use a volt/ohmmeter with high impedance (10 kΩ/V

minimum) 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 the

test light.
The short lies between the connector where the test light
stays lit and the connector where the light goes out.

(e) Find the exact location of the short by lightly shaking the

problem 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) of

the digital meter, be careful that no part of your body or
clothing comes in contact with the terminals of leads
from the IC, etc. of the replacement part (spare part).

DISCONNECTION OF MALE AND FEMALE
CONNECTORS

To pull apart the connectors, pull on the connector itself, not
the wire harness.

HINT : Check to see what kind of connector you are

disconnecting before pulling apart.

E GLOSSARY OF TERMS AND SYMBOLS

BATTERY

Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto’s
various electrical circuits.

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.

CAPACITOR (Condenser)

A small holding unit for temporary
storage of electrical voltage.

HEADLIGHTS

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

1. SINGLE
FILAMENT

CIGARETTE LIGHTER

An electric resistance heating
element.

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

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.

LIGHT

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

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

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

FUSIBLE LINK

METER, DIGITAL

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

FUEL

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.

(for Medium Current Fuse)

(for High Current Fuse or
Fusible Link)

MOTOR

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

M

E

RELAY

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

1. NORMALLY
CLOSED

2. NORMALLY
OPEN

SWITCH, MANUAL

Opens and closes

SPEAKER

An electromechanical device which
creates sound waves from current
flow.

RELAY, DOUBLE THROW

A relay which passes current
through one set of contacts or the
other.

Opens and closes

circuits, thereby
stopping (1) or
allowing (2) current
flow.

1. NORMALLY
OPEN

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.

operational.

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.

(Reed Switch Type)

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.

WIRES

Wires are always drawn as
straight lines on wiring
diagrams.
Crossed wires (1) without a

black dot at the junction are

(1) NOT
CONNECTED

SOLENOID

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