SCHEMATIC DIAGRAMS
The starting point of each system section is the schematic
diagram. These diagrams show how all the components
work together, such as electrical current paths from power
source to ground(via electrical load), switch connections
at each position, and other related circuit functions.
It is important to fully understand how a circuit works prior
to troubleshooting and diagnosis.

COMPONENT LOCATION INDEXES
When you want to locate the schematic components on the
vehicle, use the Component Location Index which follows
each schematic. A Component Location Index lists major
components, connectors, grounds, diodes, and their phys-
ical location and page reference. Almost all components,
connectors or grounds, and diodes shown on a schematic
can be pinpointed visually by using the Component Loca-
tion Illustrations.

TROUBLESHOOTING
INSTRUCTIONS K9A93EB1
TROUBLESHOOTING PROCEDURES
The following five-steps troubleshooting procedure is rec-
ommended.
1. Verify the customer’s complaints
Turn on all the components in the problem circuit to
check the accuracy of the customer’s complaints.
Note the symptoms. Do not begin disassembly or
testing until you have narrowed down the probable
causes.
GI-10 GENERAL
2. Read and analyze the schematic diagram
Locate the schematic for the problem circuit. Deter-
mine how the circuit is supposed to work by tracing
the current paths from the power source through the
system components to ground. If you do not under-
stand how the circuit should work, read the circuit op-
eration text. Also check other circuits that share with
the problem circuit. The name of circuits that share
the same fuse, ground, or switch, for example, are re-
ferred to on each diagram. Try to operate any shared
circuits you did not check in step 1. If the shared cir-
cuit works, the shared wiring is okay, and the cause
must be within the wiring used only by the problem cir-
cuit. If several circuits fail at the same time, the fuse
or ground is a likely cause.
3. Inspect the circuit/ component with the problem
isolated
Make a circuit test to check the diagnosis you made
in step 2. Remember that a logical, simple procedure
is the key to efficient troubleshooting. Narrow down
the probable causes using the troubleshooting hints
and system diagnosis charts. Test for the most likely
cause of failure first. Try to make tests at points that
are easily accessible.
4. Repair the problem
Once the problem is found, make the necessary re-
pairs.
5. Make sure the circuit works
Repeat the system check to be sure you have repaired
the problem. If the problem was a blown fuse, be sure
to test all of the circuits on that fuse.
TROUBLESHOOTING EQUIPMENT
VOLTMETER AND TEST LAMP
Use a test lamp or a voltmeter on circuits without solid-
state units and use a test lamp to check for voltage. A test
lamp is made up of a 12-volt light 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. When the bulb goes on, there is voltage at the
point being tested.>
CAUTION
A number of circuits include solid-state modules,
such as the Engine Control Module(ECM), used
with computer command con trol injection. Volt-
age in these circuits should be tested only with a
10-megaohm or higher impedance digital volt-met er
. Never use a test lamp on circuits that contain solid
state modules. Damage to the modules may result.
A voltmeter can be used in place of a test lamp. While a
test lamp shows whether the voltage is present or not, a
voltmeter indicates how much voltage is present.
TEST LAMP
EGI003A
SELF-POWERED TEST LAMP AND OHMMETER
Use a self-powered test lamp or an ohmmeter to check
for continuity. The ohmmeter shows how much resistance
there is between two points along a circuit. Low resistance
means good continuity.
CAUTION
Never use a self-powered test lamp on circuits that
contain solid state modules. Damage to these mod-
ules may result.
An ohmmeter can be used in place of a self-powered test
lamp. The ohmmeter shows how much resistance there is
between two points along a circuit. Low resistance means
good continuity.
Circuits which include any solid-state devices should be
tested only with a 10-megaohm or higher impedance dig-
ital multimeter. When measuring resistance with a digital
multimeter, the battery negative terminal should be dis-
connected. Otherwise, there may be incorrect readings.
Diodes and solid-state devices in a circuit can make an
ohmmeter give a false reading. To find out if a component
is affecting a measurement, take one reading, reverse the
leads and take a second reading. If different the solid-state
device is affecting the measurement.
SELF-
POWERED
TEST LAMP
EGI003B
JUMPER WIRE WITH FUSE
Use a jumper wire with a fuse to by-pass an open circuit.
TROUBLESHOOTING INSTRUCTIONS GI-11
A jumper wire is made up of an in-line fuse holder con-
nected to a set of test leads. This tool is available with
small clamp connectors providing adaption to most con-
nectors without damage.
CAUTION
Do not use a fuse with a higher rating than the speci-
fied fuse that protects the circuilt being tested. Do not
use this tool in any situation to substitute an input or
output at the solid-state control module, such as ECM,
TCM, etc.
5A
EGI003C
SHORT FINDER
A short finder is available to locate a short to ground. The
short finder creates a pulsing magnetic field in the shorted
circuit and shows you the location of the short through
body trim or sheet metal.
TROUBLESHOOTING TEST
1. TESTING FOR VOLTAGE
This test measures voltage in a circuit. When testing
for voltage at a connector, you do not have to separate
the two halves of the connector. lnstead, probe the
connector from the back(backprobe). Always check
both sides of the connector because dirt and corro-
sion between its contact surfaces can cause electrical
problems.
A. Connect one lead of a test lamp or voltmeter to
a ground. If you are using a voltmeter, be sure
it is the voltmeter’s negative test lead you have
connected to ground.
B. Connect the other lead of the test lamp or volt-
meter to a selected test point(connector or termi-
nal).
C. If the test lamp glows, there is voltage present. If
you are using a voltmeter, note the voltage read-
ing. A loss of more than 1 volt from specification
indicates a problem.

2. TESTING FOR CONTINUITY
A. Disconnect the battery negative terminal.
B. Connect one lead of a self-powered test lamp or
ohmmeter to one end of the part of the circuit you
wish to test. If you are using an ohmmeter, hold
the leads together and adjust the ohmmeter to
read zero ohms.
C. Connect the other lead to the other end.
D. If the self-power test lamp glows, there is conti-
nuity. If you are using an ohmmeter, low or zero
resistance means good continuity.

3. TESTING FOR SHORT TO GROUND
A. Disconnect the battery negative terminal.
B. Connect one lead of a self-powered test lamp or
an ohmmeter to the fuse terminal on the load
side.
C. Connect the other lead to a ground.
D. Beginning near the fuse block move the har-
ness from side to side. Continue this procee-
dure(about six inches apart) while watching the
self-powered test lamp or ohmmeter.
E. When the self-powered test lamp glows, or ohm-
meter registers, there is a short to a ground in the
wiring near that point.

4. TESTING FOR A SHORT WITH A SHORT FINDER
A. Remove the blown fuse. Leave the battery con-
nected.
B. Connect the short finder across the fuse termi-
nals.
C. Close all switches in series in the circuit that is
being tested.
D. Turn on the short circuit locator. It sends pulses
of current to the short. This creates a pulsing
magnetic field around the wiring between the
fuse box and the short.
E. Beginning at the fuse box, slowly move the short
finder along the circuit wiring. The meter will
show current pulses through sheet metal and
body trim. As long as the meter is between the
fuse and the short, the needle will move with
each current pulse. Once the meter is moved
past the point of the short, the needle will stop
moving. Check around this area to locate the
cause of the short circuit.

Turn on the short circuit locator. It sends pulses
of current to the short. This creates a pulsing

Beginning at the fuse box, slowly move the short
finder along the circuit wiring. The meter will
show current pulses through sheet metal and
body trim. As long as the meter is between the
fuse and the short, the needle will move with
each current pulse. Once the meter is moved
past the point of the short, the needle will stop
moving. Check around this area to locate the cause of the short circuit. Schematic Diagram
