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
Converts low±voltage DC current
into high±voltage ignition 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.
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

Fusible Link.)

SRS (SUPPLEMENTAL RESTRAINT SYSTEM)
NOTICE: When inspecting or repairing the SRS (supplemental restraint system), 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 supplemental restraint system are difficult to confirm, so the diagnostic trouble
codes become the most important source of information when troubleshooting.
When troubleshooting the supplemental restraint system, always inspect the diagnostic trouble codes before
disconnecting the battery.
Work must be started after 90 seconds from the time the Ignition SW is set to the ªLOCKº position and the
negative (±) terminal cable is disconnected from the battery.
(The supplemental restraint system is equipped with a back±up power source so that if work is started within
90 seconds of disconnecting the negative (±) terminal cable of the battery, the SRS may be activated.)
When the negative (±) terminal cable is disconnected from the battery, memory of the clock and audio systems
will be cancelled. So before starting work, make a record of the contents momorized by each memory system.
When work is finished, reset the clock and audio system as before and adjust the clock. This vehicle has tilt
and telescopic steering, power seat and outside rear view mirror and power shoulder belt anchorage, which
are all equipped with memory function, it is not possible to make a record of the customer, and ask the
customer to adjust the features and reset the memory.
To avoid erasing the memory of each memory system, never use a back±up power supply from outside the
vehicle.
When removing the steering wheel pad or handling a new steering wheel pad, keep the pad upper surface
facing upward. Also, lock the lock lever of the twin lock type connector at the rear of the pad and take care
not to damage the connector.
(Storing the pad with its metallic surface up may lead to a serious accident if the SRS inflates for some reason.)
Store the steering wheel pad where the ambient temperature remains below 93°C (200°F), without high
humidity and away from electrical noise.
Never use SRS parts from another vehicle. When replacing SRS parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, center SRS sensor assembly or front airbag sensors.
Before repairing the body, remove the airbag sensors if during repair shocks are likely to be applied to the
sensors due to vibration of the body or direct tapping with tools or other parts.
Do not reuse a steering wheel pad or front airbag sensors.
After evaluating whether the center airbag sensor assembly is damaged or not, decide whether or not to reuse
it. (See the Repair Manual for the method for evaluating the center airbag sensor assembly.)
When troubleshooting the supplemental restraint system, use a high±impedance (Min. 10k/V) tester.
The wire harness of the supplemental restraint system is integrated with the cowl wire harness assembly and
engine wire harness assembly.
The vehicle wiring harness exclusively for the airbag system is distinguished by corrugated yellow tubing, as
are the connectors.
Do not measure the resistance of the airbag squib.
(It is possible this will deploy the airbag and is very dangerous.)
If the wire harness used in the supplemental restraint system is damaged, replace the whole wire harness
assembly.
When the connector to the airbag front sensors can be repaired alone (when there is no damage to the wire
harness), use the repair wire specially designed for the purpose.
(Refer to the Repair Manual for the applicable Model year for details of the replacement method.)
INFORMATION LABELS (NOTICES) are attached to the periphery of the SRS components. Follow the
instructions on the notices.
