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 @.

From Fuses to Relays and Components
The second half of Power Distribution shows the wiring "From Fuses to Relays and
Components." This can speed your troubleshooting by showing which circuits share fuses. lf
Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a
component in the other circuit. lf it works, you know the fuse is good and power is available to
the inooerative circuil.

Five-Step Troubleshooting
1. Verify The Complaint
Turn on all the components in the problem
circuit to check the accuracy of the customer
complaint. Note the symptoms. Do not begin
disassembly or testing until you have
narrowed down the Problem area.
2. Analyze The Schematic
Look up the schematlc for the problem
circuit. Determine how the circuit is
supposed to work by tracing the current
paths from the power source through the
circuit components to ground. Also, trace
circuits that share wiring with the problem
circuit. The names of circuits that share the
same fuse, ground, or switch, and so on' are
referred to in each circuit schematic. Try to
operate any shared circuits you didn't check
in steo 1. lf the shared circuits work, the
shared wiring is OK, and the cause must be
in the wiring used only by the problem
circuit. lf several circuits fail at the same
time, the fuse or ground is a likely cause.
Based on the symptoms and Your
understanding of the circuit's operation,
identify one or more possible causes.
3. lsolate The Problem By Testing The Circuit
Make circuit tests to check the diagnosis
you made in step 2. Keep in mind that a
logical, simple procedure is the key to
eff icient troubleshooting. Test for the most
likely cause of failure f irst. Try to make tests
at points that are easily accessible.
4. Fix The Problem
Once the specific problem is identified,
make the repair. Be sure to use proper tools
and safe procedures.
5. Make Sure The Circuit Works
Turn on all components in the repaired
circuit in all modes to make sure you've
fixed the entife problem. lf the problem was
a blown f use, be sure to test all of the
circuits on that {use. Make sure no new
problems turn up and the original problem
does not recur.
Test Equipment
CAUTION:
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 citcuits that contain solid-state
devices. Damage to the devices may result.
Test Light and DVOM
On circuits without solid-state devices, use a
test light to check for voltage. A test light is
made up of a 12 volt bulb with a pair of leads
attached. After grounding one lead, touch the
other lead to various points along the circuit
where voltage should be present. The bulb
will go on i{ there is voltage at the point being
tested. lf you need to know how much
voltage is present, use a digital
volVohmmeter (DVOM).
Selt-Powered Test Light and DVOM
Use a self-powered test light to check for
continuity. This tool is made up of a light bulb,
battery, and two leads. To test it, touch the
leads together: the light should go on.
Use a self-powered test light only on an
unoowered circuit. First, disconnect the
battery, or remove the fuse that feeds the
circuit you are working on. Select two points
in the circuit between which you want to
check continuity. Connect one lead ol the
self-powered test light to each point. lf there
is continuity, the test light's circuit will be
completed, and the light will go on.

I
SELF.POWERED TEST LIGHT

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.

Testing for Voltage Drop
Wires, connectors, and switches are designed
to conduct current with a minimum loss of
voltage. A voltage drop of more than one volt
indicates a oroblem.
1. Place the digital volvohmmeter (DVOM) in
the appropriate DC volts range. Connect
the positive lead to the end of the wire
(or to the connector or switch) closest to
the battery.
Connect the negative lead to the other
end of the wire (or the other side of the
connector or switch).
Turn on the components in the circuit.
The DVOM will show the difference
in voltage between the two points. A
difference, or drop, of more than one
volt indicates a oroblem. Check the
circuit for loose, dirty, or bent terminals.
