WIRING DIAGRAM
Provides circuit diagrams showing the circuit connections.
HOW TO USE THIS MANUAL
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power source
is received from the battery as far as each ground point. (All circuit diagrams are shown
with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit where
the problem was detected (see System Circuit section), the power source supplying
power to that circuit (see Power Source section), and the ground points (see Ground
Points section). See the System Outline to understand the circuit operation.
When the circuit operation is understood, begin troubleshooting of the problem circuit
to isolate the cause. Use Relay Location and Electrical Wire Routing sections to find
each part, junction block and wiring harness connectors, wiring harness and wiring
harness connectors, splice points, and ground points of each system circuit. Internal
wiring for each junction block is also provided for better understanding of connection
within a junction block.
Wiring related to each system is indicated in each system circuit by arrows (from
, to ). When o verall connections a re required, see the O verall Wiring Diagram
at the end of this manual.

HOW TO USE THIS MANUAL
The “Current Flow Chart” section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are
explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.
POWER SOURCE (Current Flow Chart)
The chart below shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit
Breaker, Fuse, etc.) and other parts.
The next page and following pages show the parts to which each electrical source outputs current.

POWER SOURCE
* The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CIRCUITS SECTION.
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify the
problem ground quickly. The relationship between ground points ( , , and shown below) can also be
checked this way.
GROUND POINT
* The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CIRCUITS SECTION.

TROUBLESHOOTING
VOLTAGE CHECK
(a) Establish conditions in which voltage is present at the
check point.
Example:
– Ignition SW on
– Ignition SW and SW 1 on
– Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good
ground point or negative battery terminal, and the
positive lead to the connector or component terminal.
This check can be done with a test light instead of a
voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no
voltage between the check points.
(b) Contact the two leads of an ohmmeter to each of the
check points.
If the circuit has diodes, reverse the two leads and check
again.
When contacting the negative lead to the diode positive side
and the positive lead to the negative side, there should be
continuity.
When contacting the two leads in reverse, there should be no
continuity.
(c) Use a volt/ohmmeter with high impedance (10 kΩ/V
minimum) for troubleshooting of the electrical circuit.
10
FINDING A SHORT CIRCUIT
(a) Remove the blown fuse and disconnect all loads of the
fuse.
(b) Connect a test light in place of the fuse.
(c) Establish conditions in which the test light comes on.
Example:
– Ignition SW on
– Ignition SW and SW 1 on
– Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while
watching the test light.
The short lies between the connector where the test
light stays lit and the connector where the light goes
out.
(e) Find the exact location of the short by lightly shaking
the problem wire along the body.
CAUTION
(a) Do not open the cover or the case of the ECU unless
absolutely necessary . (If the IC terminals are touched,
the IC may be destroyed by static electricity.)
(b) When replacing the internet mechanism (ECU part) of
the digital meter , be careful that no part of your body or
clothing comes in contact with the terminals of leads
from the IC, etc. of the replacement part (spare part).
DISCONNECTION OF MALE AND FEMALE
CONNECTORS
To pull apart the connectors, pull on the connector itself, not the
wire harness.
HINT: Check to see what kind of connector you are disconnecting
before pulling apart.

TROUBLESHOOTING
HOW TO REPLACE TERMINAL

construct and use the special tool or like object shown
on the left.
2. DISCONNECT CONNECTOR
3. DISENGAGE THE SECONDARY LOCKING DEVICE OR
TERMINAL RETAINER.

terminal locking clip can be released and the terminal
removed from the connector.
(b) Use a special tool or the terminal pick to unlock the
secondary locking device or terminal retainer.
NOTICE:
Do not remove the terminal retainer from connector body.
For Non–Waterproof Type Connector
HINT: The needle insertion position varies according
to the connector ’s shape (number of terminals
etc.), so check the position before inserting it.
“Case 1”
Raise the terminal retainer up to the temporary
lock position.
“Case 2”
Open the secondary locking device.
12
For Waterproof Type Connector
HINT: Terminal retainer color is different
according to connector body.
Example:
Terminal Retainer
Black or White : Gray
Black or White : Dark Gray
Gray or White : Black
“Case 1”
Type where terminal retainer is pulled up
to the temporary lock position (Pull Type).
Insert the special tool into the terminal
retainer access hole ( Mark) and pull the
terminal retainer up to the temporary lock
position.
HINT: The needle insertion position varies
according to the connector’s shape
(Number of terminals, etc.), so check the
position before inserting it.
: Connector Body
“Case 2”
Type which cannot be pulled as far as
Power Lock insert the tool straight into the
access hole of terminal retainer as shown.
13
TROUBLESHOOTING
Push the terminal retainer down to the temporary lock
position.
(c) Release the locking lug from terminal and pull the
terminal out from rear.
4. INSTALL TERMINAL TO CONNECTOR
(a) Insert the terminal.
HINT:
1. Make sure the terminal is positioned correctly.
2. Insert the terminal until the locking lug locks firmly.
3. Insert the terminal with terminal retainer in the
temporary lock position.
(b) Push the secondary locking device or terminal retainer
in to the full lock position.
