HPOWER SOURCE(Current Flow Chart)Describes power distribution from the power supply to various electricalloads. INDEXIndex of the system circuits. I 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. JGROUND POINTSShows ground positions of all the parts decribed in this manual. KOVERALLWIRING DIAGRAMProvides circuit diagrams showing the circuit connections. ffYDeùííím^l}fí”W[ shenduauto/ [gQQQ1398556747 u5íí18218750259 3 HOW TO USE THIS MANUAL This manual provides information on the electrical circuits in 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. ffYDeùííím^l}fí”W[ shenduauto/ [gQQQ1398556747 u5íí18218750259*The system shown here is an EXAMPLE ONLY.

No shading is used and only the Relay Block No. is shown to distinguish it from the J/B. Example:Indicates Relay Block No. 1. :Indicates the connector to be connected to a part (the numeral indicates the pin No.) Explanation of pin use. The pins shown are only for the highest grade, or only include those in the specification. :Connector Color Connectors not indicated are milky white in color. :() is used to indicate different wiring and connector, etc. when the vehicle model, engine type, or specification is different. :Indicates related system. :Indicates the wiring harness and wiring harness connector. The wiring harness with male terminal is shown with arrows (). Outside numerals are pin numbers. The first letter of the code for each wiring harness and wiring harness connector(s) indicates the component’s location, e.g., “E” for the Engine Compartment, “I” for the Instrument Panel and Surrounding area, and “B” for the Body and Surrounding area. When more than one code has the first and second letters in common, followed by numbers (e.g., IH1, IH2), this indicates the same type of wiring harness and wiring harness connector. :Represents a part (all parts are shown in sky blue). The code is the same as the code used in parts position. :Junction Block (The number in the circle is the J/B No. and the connector code is shown beside it). Junction Blocks are shaded to clearly separate them from other parts (different junction blocks are shaded differently for further clarification). 3B indicates that it is inside Junction Block No. 3. Example: :Indicates the wiring color. Wire colors are indicated by an alphabetical code. B=BlackL=BlueR=Red BR=BrownLG=Light GreenV=Violet G=GreenO=OrangeW=White GR=GrayP=PinkY=Yellow The first letter indicates the basic wire color and the second letter indicates the color of the stripe.Example:L – Y (Blue)(Yellow) :Indicates a wiring Splice Point (Codes are “E” for the Engine Room, “I” for the Instrument Panel, and “B” for the Body). Example: The Location of Splice Point I 5 is indicated by the shaded section. :Page No. :Indicates a sealed wiring harness. :Indicates a ground point. The first letter of the code for each ground point(s) indicates the component’s location, e.g., “E” for the Engine Compartment, “I” for the Instrument Panel and Surrounding area, and “B” for the Body and Surrounding area. :Indicates the pin number of the connector. The numbering system is different for female and male connectors. Example:Numbered in order from upper left to lower right Numbered in order from upper right to lower left :When 2 parts both use one connector in common, the parts connector name used in the wire routing section is shown in square brackets []. ffYDeùííím^l}fí”W[ shenduauto/ [gQQQ1398556747 u5íí18218750259 。。。。。。
