tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.
General Description
The chassis electrical system is a 12–volt system with a
negative ground polarity.
Wire size are appropriate to respective circuits, and
classified by color. (The classification of harnesses by
color is shown on the circuit diagram for ease of harness
identification.)
The wire size is determined by load capacity and the
length of wire required.
The vehicle harness are: body harness, chassis harness,
engine room harness, instrument harness, transmission
harness, engine ECGI harness, dome light harness, door
harness, rear body harness, tailgate harness, SRS
harness and battery cables.
The harnesses are protected either by tape or corrugated
tube, depending on harness location.
The circuit for each system consists of the power source,
wire, fuse, relay, switch, load parts and ground, all of
which are shown on the circuit diagram.
In this section, each electrical device is classified by
system.
For major parts shown on the circuit based on the circuit
diagram for each system, a summary, diagnosis of
troubles and inspection procedures are detailed.
Notes for Working on Electrical Items
Disconnecting the Battery Cable
1.All switches should be in the “OFF” position.
2.Disconnect the battery ground cable (2).
3.Disconnect the battery positive cable (1).
CAUTION:It is important that the battery ground
cable be disconnected first. Disconnecting the
battery positive cable first can result in a short
circuit.
061RW002
Connecting the Battery Cable
Follow the disconnecting procedure in the reverse order.
CAUTION:Clean the battery terminal and apply a
light coat of grease to prevent terminal corrosion.
Disconnecting the Connector
Some connectors have a tang lock to hold the connectors
together during vehicle operation.
Some tang locks are released by pulling them towards
you (1).
Other tang locks are released by pressing them forward
(2).
Determine which type of tang lock is on the connector
being handled.
Firmly grasp both sides (male and female) of the
connector.
Release the tang lock and carefully pull the two halves of
the connector apart.
D08RW128
Never pull on the wires to separate the connectors. This
will result in wire breakage as shown in the figure.
D08RW129
When removing the connector for relay (MR5B type) (3),
unfasten the tang lock of the connector by using a
screwdriver , then pull the relay out as shown in the figure.
D08RW131
Connecting the Connector
Firmly grasp both sides (male and female) of the
connector. Be sure that the connector pins and pin holes
match, Be sure that both sides of the connector are
aligned with each other.
Firmly but carefully push the two sides of the connector
together until a distinct click is heard.
D08RW130
Connector Inspection
Use a circuit tester to check the connector for continuity.
Insert the test probes (1) from the connector wire side.
D08RW132
Never insert the circuit tester test probes (2) into the
connector open end to test the continuity.
Broken or open connector terminals will result.
D08RW133
Waterproof Connector Inspection
It is not possible to insert the test probes (2) into the
connector wire side of a waterproof connector.
Use one side of a connector (1) with its wires cut to make
the test. Connect the test connector (3) to the connector
to be tested. Connect the test probes to the cut wires to
check the connector continuity.
D08RW134
Connector Pin Removal – Connector Housing Tang
Lock Type
1.Insert a slender shaft (1) into the connector housing
open end (5).
2.Push the tang lock (2) up (in the direction of the arrow
in the illustration).
Pull the wire (3) with pin (4) free from the wire side of
the connector.
D08RW135
Connector Pin Removal – Pin Tang Lock Type
1.Insert a slender shaft (1) into the connector housing
open end (5).
2.Push the tang lock (2) flat (toward the wire (3) side of
the connector.
Pull the wire with pin (4) free from the wire side of the
connector.
D08RW136
Connector Pin Insertion
1.Check that the tang lock (1) is fully up.
2.Insert the pin (3) from the connector wire (2) side.
Push the pin in until the tang lock closes firmly.
3.Gently pull on the wires to make sure that the
connector pin is firmly set in place.
D08RW137
Parts Handling
Be careful when handling electrical parts. They should not
be dropped or thrown, because short circuiting or other
damage may result.
D08RW138
Cable Harness
1.When installing the parts, be careful not to pinch or
wedge the wiring harness.
2.All electrical connections must be kept clean and
tight.
D08RW139
3.Use a grommet or guard tube to protect the wiring
harness from contacting a sharp edge or surface.
D08RW139
4. Position the wiring harness with enough clearance
from the other parts and guard the wiring harness with
a vinyl tube (2) and clips (1) to avoid direct contact.
D08RW141
5.The wiring harness between engine and chassis
should be long enough to prevent chafing or damage
due to various vibrations.
D08RW142
Splicing Wire
1.If the harness is taped, remove the tape. T o avoid wire
insulation damage, use a sewing “seam ripper”
(available from sewing supply stores) to cut open the
harness.
If the harness has a black plastic conduit, simply pull
out the desired wire.
2.Begin by cutting as little wire off the harness as
possible. Y ou may need the extra length of wire later if
you decide to cut more wire off to change the location
of a splice. You may have to adjust splice locations to
make certain that each splice is at least 1–1/2” (40
mm) away from other splices, harness branches, or
connectors.
3.When replacing a wire, use a wire of the same size as
the original wire.
Check the stripped wire for nicks or cut stands. If the
wire is damaged, repeat the procedure on a new
section of wire. The two stripped wire ends should be
equal in length.
4.Select the proper clip to secure the splice.
To determine the proper clip size for the wire being
spliced, follow the directions included with your clips.
Select the correct anvil on the crimper. (On most
crimpers your choice is limited to either a small or
large anvil.)
Overlap the two stripped wire ends and hold them
between your thumb and forefinger as shown in the
figure.
The center the spline clip (1) under the stripped wires
and hold it in place.
D08RW143
fOpen the crimping tool to its full width and rest one
handle on a firm flat surface.
fCenter the back of the splice clip on the proper anvil
and close the crimping tool to the point where the
back of the splice clip touches the wings of the clip.
fMake sure that the clip and wires are still in the correct
position. Then, apply steady pressure until the
crimping tool closes as shown in the figure.
D08RW144
Before crimping the ends of the clip (1), be sure that:
fThe wires extend beyond the clip in each direction.
fNo strands of wire are cut loose, and
fNo insulation is caught under the clip.
Crimp the splice again, once on each end.
Does not let the crimping tool (2) extend beyond the edge
of the clip or you may damage or nick the wires as shown
in the figure.
D08RW145
5.Apply 60/40 resin core solder to the opening in the
back of the clip as shown in the figure.
Follow the manufacturer’s instructions for the solder
equipment you are using.
D08RW146
6.Center and roll the splicing tape.
The tape should cover the entire splice.
Roll on enough tape to duplicate the thickness of the
insulation on the existing wires.
Does not flag the tape. Flagged tape may not provide
enough insulation, and the flagged ends will tangle
with the other wires in the harness as shown in the
figure.
D08RW147
If the wire does not belong in a conduit or other
harness covering, tape the wire again. use a winding
motion to cover the first piece of tape as shown in the
figure.

Fuse
Fuses are the most common form of circuit protection
used in vehicle wiring. A fuse is a thin piece of wire or strip
of metal encased in a glass it or plastic housing. It is wired
in series with the circuit in protects. When there is an
overload of current in a circuit, such as a short of a
ground, the metal strip is designed to burn out and
interrupt the flow of current. This prevents a surge of high
current from reaching and damaging other components in
the circuit.
Determine the cause of the overloaded before replacing
the fuse.
The replacement fuse must have the same amperage
specification as the original fuse.
Never replace a blown fuse with a fuse of a different
amperage specification.
Doing so can result in an electrical fire or other serious
circuit damage. A blown fuse is easily identified as shown
in the figure.
810RX001
Fusible Link
The fusible link is primarily used to protect circuits where
high amounts of current flow and where it would not be
practical to use a fuse. For example, the starter circuit.
When a current overload occurs, the fusible link melts
open and interrupts the flow of current so as to prevent the
rest of the wiring harness from burning.
Determine the cause of the overload before replacing the
fusible link. the replacement fusible link must have the
same amperage specification as the original fusible link.
Never replace a blown fusible link with fusible link of a
different amperage specification. Doing so can result in
an electrical fire or other serious circuit damage.
A blown fusible link is easily identified as shown in the
figure.

Bolted 80A Black 40
Bolted 100A Blue 50
Circuit Breaker
The circuit breaker is a protective device designed to
open the circuit when a current load is in excess of rated
breaker capacity. If there is a short or other type of
overload condition in the circuit, the excessive current will
open the circuit between the circuit breaker terminals.
The reset knob (1) pops out when the circuit is open. Push
the reset knob in place to restore the circuit after repairing
it.
D08RW155
Relay
Battery and load location may require that a switch be
placed some distance from either component. This
means a longer wire and a higher voltage drop (1).
The installation of a relay between the battery and the
load reduces the voltage drop (2).
Because the switch controls the relay , amperage through
the switch can be reduced.

Powertrain Control Module (PCM)
General Description
The Powertrain Control Module (PCM) is located in the
passenger compartment.
The PCM constantly monitors the information from
various sensors, and controls the systems that affect
vehicle performance.
The PCM performs the diagnostic function of the system.
It can recognize operational problems, alert the driver
through the Malfunction Indicator Light (MIL) and store a
Diagnostic Trouble Code (DTC) or DTC(s) which identify
the problem areas to aid the technician in making repairs.
The PCM is designed to process the various input
informations and then send the necessary electrical
responses to control fuel delivery, spark timing and other
emission control systems. The input information has an
interrelation to more than one output therefore, if the one
input failed, it could affect more than one system
operation.
Refer to Driveability and Emission in Engine Section and
Automatic Transmission in Transmission section.

Headlight and Fog Light
General Description
The circuit consists of headlight, fog light, lighting switch,
dimmer·passing switch, fog light switch, high beam
indicator, lighting relay and fog light relay. When starter
switch is turned on by setting it at headlight position,
lighting relay is activated to turn on headlight. Optical axis
of headlight can be turned up or down by operating
dimmer switch while headlight is on. Passing switch is
independent of lighting switch, and optical axis of passing
light can be turned up only while switch lever is pulled up
and held in this state.
When fog light switch is turned on while headlight on at
low–beam, fog light relay is activated to turn on fog light.

Cruise Control
General Description
The circuit consists of cruise control unit, cruise main
switch, combination switch clutch switch (M/T), mode
switch (A/T), stoplight switch, actuator and indicator
lights. Cruise control system keeps the vehicle running at
a fix speed until a signal canceling this fixed speed is
received.When the cruise main switch is turned on with
the vehicle in the running mode, the battery voltage is
applied to the control unit.
When a signal from the combination switch is input to the
control unit while vehicle is in this state, the actuator is
activated to operate the system. Also, while the system is
operating, the cruise indicator light in the meter panel
lights up.
Set Function
When the cruise main switch turned on and the set switch
is depressed with the vehicle speed within the set limit
and cancel operation is refused the vehicle speed when
the set switch is released is stored in the control unit as
the set speed. But in case of the vehicle speed is over
maximum limit speed of cruise control, maximum limit
speed in the control unit is stored as the set speed.
Resume Function
Unless the vehicle speed falls below the minimum speed
limit after canceling the set speed by the cancel switch,
pushing the resume switch causes the vehicle to resume
the speed before cancellation.
Acceleration Function
During cruise control driving, pushing the acceleration
switch (on time is more than 0.6 sec.) causes an increase
in cruise speed and vehicle accelerates at a controlled
rate until acceleration switch released. Vehicle speed at
the acceleration switch released plus 1.0 km/h is stored in
the control unit as the set speed.
Top Up Function
During cruise control driving, the set speed can be
increased 1.6 km/h each time by operating the
accelerator switch quickly within 0.6 sec.
Coast Function
During cruise control driving, pushing the coast switch (on
time is more than 0.6 sec.) causes a decrease in cruise
speed and the vehicle decelerate at a controlled rate until
coast switch released. Vehicle speed at the coast switch
released ,minus 1.0 km/h is stored in the control unit as
the set speed.
Top down Function
During cruise control driving, the set speed can be
lowered 1.6 km/h each time by operating the coast switch
quickly within 0.6 sec.
Cancel Function
During cruise control driving, the cruise control is
released if the control unit receives a signal from the
cancel switch, mode switch, clutch switch or brake
switch. But the set speed is not erased.
Down Cancel Function
The cruise control is canceled when the vehicle speed
becomes the set speed minus 20 km/h during the cruise
control working and the set speed is erased.
Over Drive (OD) Cancel Function
OD cancel function is required when the vehicle speed
becomes the set speed minus 3 km/h during the cruise
control working. OD cancel function is enabled when the
acceleration function and/or resume function are working
except the vehicle speed is in more than 120 km/h.

Anti–Lock Brake System (ABS)
General Description
The circuit consists of the starter switch, stoplight switch
EHCU wheel speed sensor, ABS warning light, BRAKE
warning light, and data link connector.
When the service brake is applied while in the running
mode, the EHCU (Electronic Hydraulic Control Unit)
judges which wheel is about to lock by using the wheel
rotation speed signals sent from the three wheel speed
sensors at the front wheels and rear differential. And the
brake fluid pressure applied to the four wheels is
controlled by the EHCU to prevent the wheels from
locking.
Refer to Brake Control System in Brakes section in detail.

A/T Shift Lock
General Description
With the starter switch in the “ON” position and the shift
lever in “P” position, the shift lever cannot be shifted from
“P” to another position unless the brake pedal is
depressed. This is because, unless the brake pedal is
depressed, the solenoid pin underneath the shift lever
retracts and the link lever then locks the shift lever cam.

each vehicle are added to the signal. But, when
starter switch is on or any of the doors opens,
lock/unlock function is not unable to work.
2.Answer back function
When receiving the signal from the transmitter, the
keyless entry control unit responds by using the dome
light. In case of being locked, the keyless entry control
unit turns on the dome light at two times (about 0.5
second at each time). In case of being unlocked, it
turns on the dome light at one time (about 3 seconds).
3.Autolock function
After unlock function is done, in case of effecting one
of following conditions within about 30 seconds, the
keyless entry control unit automatically sends the
lock signal to lock each door.
1. The doors are closed.
2. Starter key is not inserted

Heater and Air Conditioning
General Description
Using the signals from a variety of sensors, the full
automatic heater and air conditioning system accurately
senses outside air temperature, solar radiation quantity,
evaporator’s blowing temperature, heater core water
temperature and interior temperature. These signals
enable the control unit to automatically control blow
temperature and air blow quantity, turn on or off the
compressor and switch the blow port as well as switching
between the fresh air intake and interior air circulation.
Resetting the automatic function allows the system to
switch to the manual control mode.
The self-diagnosis function of the control unit allows the
unit to access and diagnose failed parts easier and
quicker.
Refer to Air Conditioning System in HVAC System.

Sunroof
General Description
The circuit consists of the starter switch, sunroof switch,
sunroof control unit, limit switch, and sunroof motor.
When the sunroof switch is turned on, the battery voltage
is applied to the sunroof control unit through the circuit
breaker and the power window relay on the circuit.
Accordingly, when the sunroof switch is set to “Open” or
“Close” position, the open or close relay incorporated into
the control unit is activated to change the rotational
direction of the sunroof motor to open or close the
sunroof.
Also, the operational process (full close → limit stop → full
open → safety stop → full close) of the sunroof is
controlled by the control unit in accordance with signals
received from the sunroof switch and limit switch.

Supplemental Restraint System (SRS) – Air Bag
General Description
The circuit consists of Sensing and Diagnostic Module
(SDM), driver’s air bag assembly, SRS coil assembly,
passenger’s air bag assembly, and “AIR BAG” warning
light. SDM, SRS coil assembly (driver side only), driver air
bag assembly, passenger air bag assembly and
connector wire make up the deployment loops. The
function of the deployment loops is to supply current
through air bag assembly, which will cause deployment of
the air bags in the event of a frontal crash of sufficient
force, up to 30 degrees off the center line of the vehicle.
The air bag assemblies are only supplied enough current
to deploy when the SDM detects vehicle velocity changes
severe enough to warrant deployment.
The SDM contains a sensing device which converts
vehicle velocity changes to an electrical signal.
The electrical signal generated is processed by the SDM
and then compared to a value stored in memory. When
the generated signal exceeds the stored value, the SDM
will cause current to flow through the air bag assembly
deploying the air bags.
Refer to Supplemental Restraint System (SRS) and
Restraint Control System in Restraints.
