Circuit Description
The major role and, operation of the circuit
and its component parts are explained.
Diagnostic Trouble Code No. and Detection Item Indicates the diagnostic trouble codes, diagnostic
trouble code settings and suspect areas for a
problem.
Wiring Diagram
This shows a wiring diagram of the circuit.
Use this diagram together with ELECTRICAL
WIRING DIAGRAM to thoroughly understand the
circuit.
Wire colors are indicated by an alphabetical code.
B = Black, L = Blue, R = Red, BR = Brown,
LG = Light Green, V = Violet, G = Green,
O = Orange, W = White, GR = Gray, P = Pink,
Y = Yellow, SB = Sky Blue
The first letter indicates the basic wire color and
the second letter indicates the color of the stripe. Inspection Procedures
Use the inspection procedures to determine
if the circuit is normal or abnormal. If it is ab-
normal, use it to determine whether the prob-
lem is located in the sensors, actuators, wire
harness or ECU.
Indicates the condition of the connector of the ECU
during the check.

Connections of tester are
indicated by (+), (±) after
terminals name.
Connector being checked
is connected.Connector being checked
is disconnected.
For inspection of connector
with body ground, there is
nothing about the body
ground written down.

HINT:
The type of connector is shown in the diagram on the previous
page.
(3) Electrical connection check mechanism:This mechanism electrically checks that the con-
nectors are connected correctly and completely.
The electrical connection check mechanism is de-
signed so that the disconnection detection pin con-
nects with the diagnosis terminals when the con-
nector housing lock is locked.
HINT:
The connectors shown in this illustration are connectors, º1º,
º2º, º3º and º4º in the step 1. (4) Half connection prevention mechanism:
If the connector is not completely connected, the
connector is disconnected due to the spring opera-
tion to the extent that no continuity exists.

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 t\
he power
source is received from the battery as far as each ground point. (All c\
ircuit
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 poin\
ts
(see Ground Point section). See the System Outline to understand the c\
ircuit
operation.
When the circuit operation is understood, begin troubleshooting of the p\
roblem
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 b\
etter
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arr\
ows
(from__, to__). When overall connections are required, see the Overall\
Electrical
Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major p\
arts 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 (
EA, IB and IC shown below) can also be
checked this way.

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 condition\
s when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power so\
urce, the power source system must be fully
understood.

circuits, particularly the primary
ignition circuit, to become

and close a switch to create a signal
for activation of other components.TRANSISTORA solidstate device typically used as
an electronic relay; stops or passes
current depending on the voltage
applied at ”base”.
