HOW TO USE THIS MANUAL B
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 Wiring 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
Wiring Diagram at the end of this manual.

B 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.
H 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 shown 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.
B
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

J GROUND POINT
* The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the SYSTEM CIRCUITS SECTION.

C TROUBLESHOOTING
VOLTAGE CHECK
(a) Establish conditions in which voltage is
check point.
Example:
A – Ignition SW on
B – Ignition SW and SW 1 on
C – Ignition SW, SW 1 and Relay on (SW2 off)
(b) Using a voltmeter, connect the negative lead to a
ground point or negative battery terminal, and a
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 point.
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 the volt/ohmmeter with high impedance (10kΩ/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:
A – Ignition SW on
B – Ignition SW and SW 1 on
C – 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:
C
(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 internal 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.

according to the connector’s shape
(number of terminals etc.), so check
the position before inserting it.
“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
C TROUBLESHOOTING
Push the terminal retainer down to the temporary lock
