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

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 H : Represents a part (all parts are shown in sky blue) The code is the same as the code used in parts position I : 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) L : Page No M : Indicates a shielded cable N : 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 O : 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 Example: 3B indicates that it is inside Junction

short terminal installed (When installing the wire harnesses, the harnesses can be connected to any position within the short terminal grouping Accordingly, in other vehicles, the same wire harness from a different part.) Wire harness sharing the same short terminal grouping have the same color 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 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 show 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 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 shown below) can also be checked this way GROUND POINT * The system shown here is an EXAMPLE ONLY It is different to the actual circuit shown in the SYSTEM CIRCUITS SECTION TROUBLESHOOTING VOLTAGE CHECK (a) Establish conditions in which voltage is present at the check point Example: (b) – Ignition SW on – Ignition SW and SW on – Ignition SW, SW and Relay on (SW off) Using a voltmeter, connect the negative lead to a good ground point or negative battery terminal, and the 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) (b) Disconnect the battery terminal or wire so there is no voltage between the check points Contact the two leads of an ohmmeter to each of the check points 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) 10 Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting of the electrical circuit 23 CAM RY 4 1L B W
