- ABBREVIATIONS : Defines the abbreviations used in this manual

- GLOSSARY OF TERMS AND SYMBOLS : Defines the symbols and functions of major parts.

- RELAY LOCATIONS : Shows position of the Electronic Control Unit, Relays, Relay Block, etc.This section is closely related to the system circuit.

- ELECTRICAL WIRING ROUTING : Describes position of Parts Connectors, Splice points, Ground points, etc.This section is closely related to the system circuit

- POWER SOURCE (Current Flow Chart) : Describes power distribution from the power supply to various electrical loads.

- SYSTEM CIRCUITS : Electrical circuits of each system are shown from the power supply through ground points. Wiring connections and their positions are shown and classified by code according to the connection method. (Refer to the section, “How to use this manual”). The “System Outline” and “Service Hints” useful for troubleshooting are also contained in this section.

- GROUND POINTS : Shows ground positions of all the parts described in this manual

- OVERALL ELECTRICAL WIRING DIAGRAM : Provides circuit diagrams showing the circuit connections

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