METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to
move, thereby providing a relative
display against a background
calibration. LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes
emit light without producing the
heat of a comparable light. IGNITION COIL
Convert low-voltage DC current
into high-voltage ingition current
for firing the spark plugs. 1. SINGLE
FILAMENT
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.
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. 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.
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.
DIODE
A semiconductor which allows
current flow in only one direction.
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.
PHOTODIODE
The photodiode is a semiconductor
which controls the current flow
according to the amount of light.
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
A heavy-gauge wire placed in
high amperage circuits which
burns through on overloads,
thereby protecting the circuit.
The numbers indicate the cross-
section surface area of the wires.HORN
An electric device which sounds a
loud audible signal.
LIGHT
Current flow through a filament
causes the filament to heat up
and emit light.
METER, DIGITAL
Current flow activates one or
many LED's, LCD's, or fluorescent
displays, which provide a relative
or digital display.
MOTOR
A power unit which converts
electrical energy into mechanical
energy, especially rotary motion. CIGARETTE LIGHTER
An electric resistance heating
element.
DISTRIBUTOR, IIA
Channels high-voltage current
from the ignition coil to the
individual spark plugs.2. DOUBLE
FILAMENT HEADLIGHTS
FUEL
(for High Current Fuse or
Fusible Link.)

1996 RAV4 (RM447U)
INSPECTION
1. VEHICLE NOT INVOLVED IN COLLISION
(a) Do a diagnostic system check (See page DI−285).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check for cuts, minute cracks or marked discoloration of
the steering wheel pad top surface and grooved portion.
2. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Do a diagnostic system check (See page DI−285).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check for cuts and cracks in, or marked discolor-
ation of the steering wheel pad top surface and
grooved portion.
Check for cuts and cracks in wire harnesses, and for
chipping in connectors.
Check for deformation of the horn button contact
plate of the steering wheel.
HINT:
If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.
There should be no interference between the steering
wheel pad and the steering wheel, and the clearance
should be uniform all the way around when the new steer-
ing wheel pad is installed on the steering wheel.
CAUTION:
For removal and installation of the steering wheel pad, see
page SR−12 and SR−19, and be sure to follow the correct
procedure.
