    How To Use This Manual

    The next few pages describe how this manual is organized. They also

    explain what kind of information the manual contains, what the

    information means, and how to use it to troubleshoot electrical problems.

    Circuit schematics break the entire electrical system into individualsystems, like the Back-up Lights on the next page. Only electrical

    components that work together are shown together, so you wont be

    distracted by unrelated wires.

    Explanations of the abbreviations and symbols used in the schematics

    begin on page . Youll need to know what they mean before you can use

    a schematic effectively.7

    Circuit Schematics

    Each schematic represents one circuit. Acircuits wires and components are arranged toshow current flow, from power at the top of thepage, to ground at the bottom.

    Shared Circuits

    Other circuits may share power or groundterminals or wiring with the circuit shown. Awire that connects one circuit to another, forexample, is cut short and has an arrowhead atthe end of it pointing in the direction of currentflow. Next to the arrowhead is the name of thecircuit or component which shares that wiring.To quickly check shared wiring, check theoperation of a component it serves. If thatcomponent works, you know the shared wiringis OK.

    ConnectorsAll in-line and junction connectors arenumbered (C725, C416, etc.). Componentconnectors are not numbered but are identifiedeither by the name of the component if thecomponent only has one connector, or by acapital letter (A, B, C, etc.) if the componenthas more than oneconnector.

    Below most connector numbers andcomponent names are PHOTO and VIEWnumbers. The PHOTO numberrefers to a photo in the back of the bookthat shows the connectors location on the car.The VIEW number refers to an illustration inthe back of the book that shows the connectorterminals, wire colors, connector cavitynumbers, and other details.

    The connector cavity numbering sequencebegins at the top left corner of the connectoras seen from either of the viewpoints shownon page . Except for the DLC (data linkconnector), disregard any numbers moldedinto the connector housing.

    Wires

    Wires are identified by the abbreviated names

    of their colors; the second color is the color ofthe stripe. Wires are also identified by theirlocation in a connector. The number 2 next tothe male and female wire terminals at C554, forexample, means those terminals join in cavity 2of connector C554.

    Power Distribution schematics show how power is supplied from the positive battery terminal to

    various circuits in the vehicle. Refer to the Power Distribution section to get a more detailed

    understanding of how power is supplied to the circuit you are working on. Individual circuit

    schematics begin with a fuse. So, if Power Distribution shows that an inoperative circuit andanother circuit share a fuse, check a component in the other circuit. If it works, you know the fuse

    is good, and power is available to the inoperative circuit.

    How To Use This Manual

    Connector Terminal Views

    To see the configuration of a connectors cavities, look up its view number in the Connector

    View section that begins on page 202. Each view includes the color of the connector, where

    it is located, and what it connects to.

    Use the Connector View Section to help locate the proper cavity when you need to test aconnector. It can be especially helpful if the connector has more than one wire of the same

    color. A dash symbol ( ) indicates that the cavity is empty.

    Connector views can also be used to help diagnose multiple symptoms in separate circuits

    that could be caused by a single problem in a connector shared by those circuits. Heres

    how:

    1 Pick one of the multiple symptoms and look up the schematic for that circuit.

    2 Make a list of all the in-line and fuse box connectors in that schematic (include page

    numbers).

    3 Then, in the Connector View section, look up each connector on your list to see if circuits

    related to the other symptoms run through one of them. If they do, inspect that connector

    for the problem.

    Example: The blower, rear window defogger, and the windshield wiper dont work. List all

    in-line and fuse box connectors in the blower controls circuit and then check the Connector

    View section (sample below). You find that C324 is common to the rear window defogger

    circuit and wiper/washer circuit, so you inspect C324 and find the problem: damaged

    terminals.

    Light Emitting Diode (LED)

    LEDs are special diodes that emit light when

    connected in a circuit. LEDs work the same

    as a rectifier diode by allowing current to flowonly in one direction.

    Resistor

    This symbol represents a component in

    electrical circuits that resists the flow of

    electrical current. Resistance is denominatedin Ohms. Higher resistance results in less

    current flow. This type of resistor has a fixed

    resistance value.

    Motor

    This symbol represents a DC voltage

    electrical motor. Motors can reverse direction

    by changing the polarity of the voltage.

    Variable Resistor

    This symbol represents a component in

    electrical circuits that resists the flow ofelectrical current. Resistance is denominated

    in Ohms. Higher resistance results in less

    current flow. This type of resistor (thermistor)

    has a variable resistance value that changes

    with temperature. The resistance of a

    thermistor decreases as temperature

    increases.

    Pressure Sensor

    A pressure sensor is a variable resistor used

    to monitor the difference in pressure between

    the intake manifold and outside atmosphere

    (Map Sensor). This information is used by

    the engine computer to monitor engine load

    (vacuum drops when the engine is under loador at wide open throttle). When the engine is

    under load, the computer alters spark timing

    and the fuel mixture to control performance

    and emissions.

    NOTE: There is also a FTP (Fuel Tank

    Pressure) Sensor used to monitor EVAP

    System testing.

    Solenoid

    An electromagnet is produced by current

    flowing through a coil of wire. A plunger inside

    the wire coil is moved by the electromagnet

    turning ON or OFF.

    Transistors

    Transistors are electrical devices that havetwo key properties: 1) they can amplify an

    electrical signal and 2) they can switch ON

    and OFF, letting current through or blocking it

    as necessary.

    Five-Step Troubleshooting Test Equipment

    1. Verify The Complaint

    Turn on all the components in the problemcircuit to check the accuracy of the

    customer complaint. Note the symptoms.Do not begin disassembly or testing untilyou have narrowed down the problem area.

    2. Analyze The Schematic

    Look up the schematic for the problemcircuit. Determine how the circuit issupposed to work by tracing the currentpaths from the power source through thecircuit components to ground (certaincircuits contain a How the Circuit Workssection). Also, trace circuits that sharewiring with the problem circuit. The names

    of circuits that share the same fuse,ground, or switch, and so on, are referredto in each circuit schematic. Try to operateany shared circuits you didnt check in step1. If the shared circuits work, the sharedwiring is OK, and the cause must be in thewiring used only by the problem circuit. Ifseveral circuits fail at the same time, thefuse or ground is a likely cause.

    Based on the symptoms and yourunderstanding of the circuits operation,identify one or more possible causes.

    3. Isolate The Problem By Testing The Circuit

    Make circuit tests to check the diagnosisyou made in step 2. Keep in mind that alogical, simple procedure is the key toefficient troubleshooting. Test for the mostlikely cause of failure first. Try to maketests at points that are easily accessible.

    4. Fix The Problem

    Once the specific problem is identified,make the repair. Be sure to use proper

    tools and safe procedures.

    5. Make Sure The Circuit Works

    Turn on all components in the repairedcircuit in all modes to make sure youvefixed the entire problem. If the problemwas a blown fuse, be sure to test all of thecircuits on that fuse. Make sure that nonew problems turn up and that the originalproblem does not recur.

    CAUTION:

    Most circuits include solid-state devices.Test the voltages in these circuits only with

    a 10-megaohm or higher impedance digitalmultimeter. Never use a test light or analogmeter on circuits that contain solid-statedevices. Damage to the devices may result.

    Test Light and DVOM

    On circuits without solid-state devices, usea test light to check for voltage. A test lightis made up of a 12 volt bulb with a pair ofleads attached. After grounding one lead,touch the other lead to various points alongthe circuit where voltage should be present.

    The bulb will go on if there is voltage at thepoint being tested. If you need to know howmuch voltage is present, use a digitalvolt/ohmmeter (DVOM). If, in addition, youneed to know exactly how much resistancethere is between two points, use a digitalvolt/ohmmeter (DVOM).

    In the OHMS range, the DVOM will measureresistance between two points along a circuit.Low resistance means good continuity.

    Diodes and solid-state devices in a circuit can

    make a DVOM give a false reading. To checka reading, reverse the leads, and take asecond reading. If the readings differ, thecomponent is affecting the measurement.

    To order any test equipment shown above,contact your local tool supplier. For a list ofsuppliers and tool numbers, refer to HondaRequired Special Tools and EquipmentService Bulletin.

    D Most circuits include solid-statedevices. Test the voltages in thesecircuits only with a 10-megaohm orhigher impedance digital multimeter.Never use a test light or analog meter oncircuits that contain solid-state devices.Damage to the devicesmay result.

    Troubleshooting Precautions

    Jumper Wire

    Use a jumper wire to bypass an open circuit.A jumper wire is made up of an in-line fuse

    holder connected to a set of test leads. Itshould have a five ampere fuse. Neverconnect a jumper wire across a short circuit.The direct battery short will blow the fuse.

    Before Troubleshooting

    1. Check the main fuse and the fuse box.

    2. Check the battery for damage, state ofcharge, and clean and tight connections.

    CAUTION:

    D Do not quick-charge a battery unlessthe battery ground cable has beendisconnected, or you will damage thealternator diodes.

    D Do not attempt to crank the engine withthe ground cable disconnected or youwill severely damage the wiring.

    While Youre Working

    1. Make sure connectors are clean, and haveno loose terminals or receptacles.

    2. Make sure that connectors without wireseals are packed with dielectric (silicone)grease. Part Number: 08798-9001.

    To order any test equipment shown above,contact your local tool supplier. For a list ofsuppliers and tool numbers, refer to HondaRequired Special Tools and EquipmentService Bulletin.

    Testing for Voltage

    When testing for voltage at a connector withoutwire seals, you do not have to separate thetwo halves of the connector. Instead, probe theconnector from the back. Always check bothsides of the connector because dirty, corroded,and bent terminals can cause problems (noelectrical contact = an open).

    1. Connect one lead of the test light to aknown good ground, or, if youre using adigital volt ohmmeter (DVOM), place it inthe appropriate DC volts range, andconnect its negative lead to ground.

    2. Connect the other lead of the test light orDVOM to the point you want to check.

    3. If the test light glows, there is voltage

    present. If youre using a DVOM, note thevoltage reading. It should be within one voltof measured battery voltage. A loss of morethan one volt indicates a problem.

    NOTE: Always use a DVOM on highimpedance circuits. A test light may notglow (even with battery voltage present).

    Testing for Continuity

    When testing for continuity at a connectorwithout wire seals, you do not have to separatethe two halves of the connector. Instead, probethe connector from the back. Always checkboth sides of the connector because dirty,corroded, and bent terminals can causeproblems (no electrical contact = an open).

    1. Disconnect the negative cable from thevehicle battery. If youre using a DVOM,place it in the lowest OHMS range.

    2. Connect one lead of a DVOM to one end ofthe part of the circuit you want to test.

    3. Connect the other lead to the other end.

    4. If youre using a DVOM, a low reading or noreading (zero), means good continuity.

    How To Use This Manual

    Testing for Voltage Drop

    Wires, connectors, and switches are designedto conduct current with a minimum loss ofvoltage. A voltage drop of more than one voltindicates a problem. Circuits must be operatingwhen checking voltage drop.

    1. Place the digital volt/ohmmeter (DVOM) inthe appropriate DC volts range. Connect thepositive lead to the end of the wire(or to the connector or switch) closest to thebattery.

    2. Connect the negative lead to the other endof the wire (or the other side of theconnector or switch).

    3. Turn on the components in the circuit.

    4. The DVOM will show the differencein voltage between the two points. Adifference, or drop, of more than onevolt indicates a problem. Check thecircuit for loose, dirty, or bent terminals.

    Testing for a Short with a Test Light or DVOM

    1. Remove the blown fuse and disconnectthe load.

    2. Connect a test light or digital volt/ohmmeter(DVOM), switched to the appropriate DCvolts range, across the fuse terminals tomake sure voltage is present. You mighthave to turn the ignition switch to ON; checkthe schematic to see.

    3. Beginning near the fuse box, wiggle theharness. Continue this at convenient pointsabout six inches apart while watching thetest light or DVOM.

    4. Where the test light goes off, or the DVOMvoltage drops to zero, there is a short to

    ground in the wiring near that point.

    NOTE: Always use a DVOM on highimpedance circuits. A test light may notglow (even with battery voltage present).
