                                                    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 Point 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__, to__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
    [O]          SYSTEM OUTLINE
            Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
            When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows
            through the rear lights warning light to TERMINAL 4 of the light failure sensor.
           STOP LIGHT DISCONNECTION WARNING
           When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current
           flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the
           disconnection and the warning circuit of the light failure sensor is activated.
           As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights
           warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning
           circuit on and holds the warning light on until the ignition SW is turned off.

B HOW TO USE THIS MANUAL
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 ( 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 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.

           J 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.
