Circuit Schematics
Each schematic reoresents one circuit.
A circuit's wires and components are
arranged to show current flow, from
power at the top of the page, to ground,
at the bottom.
Other circuits may share power or ground
terminals or wiring with the circuit shown.
A wire that connects one circuit to
another, lor example, is cut short and has
an arrowhead at the end of it pointing in
the direction of current flow. Next to the
arrowhead is the name ol the circuit or
component which shares that wiring. To
quickly check shared wiring, check the
operation of a component it serves. lf that
component works, you know the shared
wiring is OK.
All connectors are numbered (C709,
C416, etc.). Below each connector
number (except those for components)
is the number of a ohoto in the back
of the book showing the connector's
location on the car. Connector cavities
are also numbered. The numbering
sequence begins at the top left corner
of the connector as seen from eilher of
the viewpoints shown on page E.
Disregard any numbers molded into the
connector housing.
Wires are identif ied by the abbreviated
names of their colors; the second color is
the color of the stripe. Wires are also
identif ied by their location in a connector.
The number "2" next to the male and
female wire terminals at C416, for
example, means those terminals join in
cavity 2 of connector C41 6.
A complete description of schematic
symbols begins on page @.
O,e
Arowhead meanswire connects toanother ciacuit;it points in directionof current tlow.
"OK" note tellsYou how tocheck sharedwiring.
"HOT" label tells you whenthe ignition switch suppliesDower lo the fuse. \\

Component Locations
To see where a component or connector is located on the car, look up its photo number in the
Component Location section in the back of the book. The photo will also tell you the color of
the connector. and how manv cavities it has.

How To Use This Manual
Symbols
Ground - "G"
This symbol means the end of
the wire is attached (grounded) Ito the car frame or to a metal Ipart connected to the f rame. \I orol
,
Each wire ground (G) ," -/numbered for reference.
Q,(Switches
These switches move
together; the broken straight
line between them means thev
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted, all switches are shown
in their normal (rest) position,
with power off .
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car f rame or to a metal
part connected to the f rame.
This symbol represents
the bus bar inside a ground
connector. The dots a
i"r*"""*nn"l,':" .,.L I I I
lermtnals connectto. -'--'-:t"'--------<
The ground symbol (large dot)
: Gsoo
is the connection between the
bus bar and metal (grounded)
part of the car.
Terminals - "T"
m
ffi
Solid-state
Fuses
This means power is supplied
when the ignition switch is in ON (ll).
Diodes
A rectifier diode works like a one
way valve. lt allows current to
flow only in the dlrection of the
arrow.
A Zener diode blocks reverse
currenl at normal voltages just like
a rectifier diode. At high voltages,
however, a Zener diode allows
current to flow in reverse.
Q,(
Each 'T" terminal (ring type)
is numbered for reference ano
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interf erence) shielding
around a wire. The
shielding is always
connected to ground.

How To Use This Manual
Test Equipment
lf, in addition, you need to know exactly how
much resistance there is between two ooints.
use a digital volVohmmeter (DVOM).
In the "oHMS" range, the DVOM will show
resistance between two points along a circuit.
Low resistance means good continuity.
Diodes and solid-state devices in a circuit can
make a DVOM give a false reading. To check
a reading, reverse the leads, and take a
second reading. lf the readings differ, the
component is affecting the measurement.
Jumper Wire
Use a jumper wire to bypass an open circuit.
A jumper wire is made up of an in-line f use
holder connected to a set of test leads. lt
should have a tive ampere fuse. Never
connect a jumper wire across a short circuit.
The direct battery short will blow the fuse.
Short Finder (Short Circuit Locater)
Shoft linders are available to locate shorts to
ground. The short finder creates a pulsing
magnetic field in the shorted circuit which you
can follow to the location of the short. lts use
is explained on page 15.
SHORT FINDER
To order any test equipment shown above,
contact your local tool supplier. For a list of
suppliers and tool numbers, refer to Acura
Required Special Tools and Equipment
Service Bulletin.
Troubleshooting Precautions
Before Troubleshooting
1. Check the main fuse and the fuse box.
2. Check the battery for damage. state of
charge, and clean and tight connections.
CAUTION:
. Do not quick-charge a battery unless
the battery ground cable has been
disconnected, or you will damage the
alternator diodes.
. Do not attempt to crank the engine with
the ground cable disconnected or you
will severely damage the wiring.
While You're Working
1. Make sure connectors are clean, and have
no loose terminals or receotacles.
2. Make sure multiple terminal connectors are
packed with dielectric (silicone) grease.
Part Number: 08798-9001 .
Pack with dielectric (silicone) grease
When connecting a connector, push it until it
clicks into olace.
Do not pull on the wires when
disconnecting a connector. Pull
only on the connector housings.
Most circuits include solid-state
devices. Test the voltages in these
circuits only with a 1o-megaohm or
higher impedance digital multimeter.
Never use a test light or analog meter
on circuits that contain solid-state
devices. Damage to the devices
may result.
