Wire Color Coding

Distinct Of Circuit By Wire Base Color

All wires have color-coded insulation.Wires belonging to a system's main harness will have a single color. Wires belonging to a system's sub-circuits will have a colored stripe. Striped wiresuse the codes found in the chart to show wire size and colors.
Abbreviations are used to indicate wire color within a circuit diagram.

How to Identify Connector Terminals

How to Identify Connector TerminalsCavity Numbering System

The cavities (and wire terminals) in each connector are numbered starting from the upper left, looking at the male terminals from the terminal side (orlooking at the female terminals from the wire side. Both views are in the same direction so the numbers are the same.) All actual cavities are numbered,even if they have no wire terminals in them.

NOTE:

Data Link Connector (DLC) terminals are numbered according to SAE standard J1962, not the Honda standard. The numbers of the four endterminals are molded into the corners of the connector face.

CR-V EX 4WD L4-1972cc 2.0L DOHC MFI (2000)

The connector cavity number is listed next to each terminal on the circuit schematic. The cavity / terminal shown is # 6.

Using/Identifying Connector Terminal Views
How to Use Connector Terminal Views

To see the configuration of a connector's cavities, look up its view number in the Connector Views. Each view includes the color of the connector, where

it is located, and what it connects to.Use the Connector Views to help locate the proper cavity when you need to probe a connector. It can be especially helpful if the connector has more thanone 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 which could be caused by a single problem in a connectorshared by those circuits. Here's an example:

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 ,3. Then, in the Connector Views, 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 don't work. List all in-line and fuse box connectors in the blower controls circuitand then check the Connector View (see the sample). You find that C324 is common to the blower controls, rear window defogger, and wiper/washer, soyou inspect C324 and find the problem, bent terminals.

Finding Component/Connector Locations

Finding Component/Connector Locations

To see where a component or connector is located on the car, look up its photo number in the "Component Location". The photo will also tell you thecolor of the connector, and how many cavities it has.

If there is no photo number below or beside a component name or a connector, ground, or terminal number, look up that name or number in theappropriate Connector Identification Chart. The chart lists how many cavities a connector has, where it's located, and what it connects to. The relatedillustration shows the connector's location on the harness, and the harness routing.

Photos listed by number are located at Locations / Components / Photograohs.NOTE:

Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the page, to ground,at the bottom.

Shared Circuits

Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is cut shortand has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or component whichshares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you know the shared wiring isOK.

Connectors

All in-line, pigtail, and fuse box connectors are numbered (C725, C416, etc.).

Component connectors are not numbered but are identified either by the name of the component if the component only has one connector or by a capitalletter (A, B, C, etc.) it the component has more than one connector. Below most connector numbers and component names are PHOTO and VIEWnumbers. The PHOTO number refers to a photo in the back of the book that shows the connector's location on the car. The VIEW number refers to anillustration in the back of the book that shows the connector face, wire colors, connector cavity numbers, and other details. The connector cavitynumbering sequence begins at the top left corner of the connector as seen from either of the viewpoints shown on page [9]. Disregard any numbersmolded into the connector housing.

Wires

Wires are identified by the abbreviated names of their colors; the second color is the color of the stripe. Wires are also identified by their location in aconnector. The number "2" next to the male and female wire terminals at C416, for example, means those terminals join in cavity 2 of connector C416.

Symbols

A complete description of schematic symbols begins on page [8].

Power Distribution Schematics

Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the car. Refer to the "PowerDistribution" to get a more detailed picture of how power is supplied to the circuit you're working on.

From Battery to Ignition Switch, Fuses, and Relays

Individual circuit schematics begin with a fuse. The first half of Power Distribution, however, shows the wiring "upstream" between the battery and thefuses.

From Fuses to Relays and Components

The second half of Power Distribution shows the wiring "From Fuses to Relays and Components." This can speed your troubleshooting by showingwhich circuits share fuses. If Power Distribution shows that an inoperative circuit and another 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.

Electronic Brake Control Module: Diagnostic Aids

Before Troubleshooting
Before Troubleshooting

See: Service Precautions/Vehicle Damage Warnings/Tips and Precautions

1. Check applicable fuses in the appropriate fuse/relay box.2. Check the battery for damage, state of charge, and clean and tight connections.

CAUTION:-

Do not quick-charge a battery unless the battery ground cable has been disconnected, otherwise you will damage the alternator diodes.

-

Do not attempt to crank the engine with the battery ground cable loosely connected or you will severely damage the wiring.

While You're Working

1. Make sure connectors are clean, and have no loose terminals or receptacles.

2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-9001.3. When connecting a connector, push it until it "clicks" into place.

CAUTION:-

Do not pull on the wires when disconnecting a connector. Pull only on the connector housings.

- 10-megaohm

Most circuits include solid-state devices. Test the voltages in these circuits only with a or higher impedance digital multi meter.Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result.

Five-Step Troubleshooting

1. Verify The Complaint

2. Analyze The Schematic

Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power sourcethrough the circuit components to ground. Also, trace circuits that share wiring with the problem circuit. The names of circuits that share the samefuse, ground, or switch, and so on, are referred to in each circuit schematic. Try to operate any shared circuits you didn't check in step 1. If theshared circuits work, the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several circuits fail at thesame time, the fuse or ground is a likely cause.
Based on the symptoms and your understanding of the circuit's operation, identify one or more possible causes.

3. Isolate The Problem By Testing The Circuit

and Instructions > Page 47

CR-V EX 4WD L4-1972cc 2.0L DOHC MFI (2000)

Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassemblyor testing until you have narrowed down the problem area.

Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting.Test for the most likely cause of failure first. Try to make tests 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 repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sureto test all of the circuits on that fuse. Make sure no new problems turn up and the original problem does not recur.

Test Equipment

CAUTION: 10-megaohm

Most circuits include solid-state devices. Test the voltages in these circuits only with a or higher impedance digitalmultimeter. Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result.

Test Light and DVOM

12 volt

On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a bulb with a pair of leads attached. Aftergrounding one lead, touch the other lead to various points along the circuit where voltage should be present. The bulb will go on if there is voltage at thepoint being tested. If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM).

Self-Powered Test Light and DVOM

Use a self-powered test light to check for continuity. This tool is made up of a light bulb, battery, and two leads. To test it, touch the leads together: thelight should go on.

Use a self-powered test light only on an unpowered circuit. First, disconnect the battery, or remove the fuse that feeds the circuit you are working on.Select two points in the circuit between which you want to check continuity. Connect one lead of the self-powered test light to each point. If there iscontinuity, the test light's circuit will be completed, and the light will go on.
If, in addition, you need to know exactly how much resistance there is between two points, use a digital volt/ohmmeter (DVOM).

In the "OHMS" range, the DVOM will measure resistance 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 check a reading, reverse the leads, and take a second reading. Ifthe readings differ, the component is affecting the measurement.

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. It should have a fiveampere fuse. Never connect a jumper wire across a short circuit. The direct battery short will blow the fuse.

Short Finder (Short Circuit Locator)

Short finders are available to locate shorts to ground. The short finder creates a pulsing magnetic field in the shorted circuit which you can follow to thelocation of the short.

To order any test equipment shown above, contact your local tool supplier. For a list of suppliers and tool numbers, refer to Honda Required SpecialTools and Equipment Service Bulletin.

Testing For A Short With A Self-Powered Test Light or DVOM

1. Remove the blown fuse and disconnect the battery and load.

2. Connect one lead of a self-powered test light or digital volt/ohmmeter (DVOM) (switched to the lowest "OHMS" range) to the fuse terminal on the
load side.

3. Connect the other lead to a known good ground.4. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about apart while watching the test light or DVOM.six inches

5. If the self-powered test light goes on or the DVOM displays a low reading or no reading (zero), there is a short to ground in the wiring near that
point.

Testing for a Short with a Test Light or DVOM

1. Remove the blown fuse and disconnect the load.

CR-V EX 4WD L4-1972cc 2.0L DOHC MFI (2000)

2. Connect a test light or digital volt/ohmmeter (DVOM), switched to the appropriate DC volts range, across the fuse terminals to make sure voltage
is present. You might have to turn the ignition switch to ON; check the schematic to see.

six inches

3. Beginning near the fuse box, wiggle the harness. Continue this at convenient points about apart while watching the test light or DVOM.4. Where the test light goes , or the DVOM voltage drops to zero, there is a short to ground in the wiring near that point.

Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).NOTE:

Testing For A Short With A Short Circuit Locator (Short Finder)

1. Remove the blown fuse. Leave the battery connected.

2. Connect the short finder across the battery terminals and the load (component) side of the fuse terminal.3. Close all switches in the circuit you're testing.4. Turn on the short finder. This creates a pulsing magnetic field around the wiring between the fuse box and the short.5. Beginning at the fuse box, slowly move the short finder along the circuit wiring. The meter will read current pulses through sheet metal and body
trim. As long as the meter is between the fuse and the short, the needle will move with each current pulse. Once you move the meter past the pointof the short, the needle will stop moving. Check the wiring and connectors in this area to locate the cause of the short.

Testing For Continuity

When testing for continuity at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connectorfrom the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = anopen).

1. Disconnect the negative cable from the car battery. If you're using a DVOM, place it in the lowest "OHMS" range.

and Instructions > Page 50

CR-V EX 4WD L4-1972cc 2.0L DOHC MFI (2000)

2. Connect one lead of a self-powered test light or DVOM to one end of the part of the circuit you want to test.3. Connect the other lead to the other end.4. If the self-powered test light glows, there is continuity. If you're using a DVOM, a low reading or no reading (zero), means good continuity.

Testing For Voltage

When testing for voltage at a connector without wire seals, you do not have to separate the two halves of the connector. Instead, probe the connectorfrom the back. Always check both sides of the connector because dirty, corroded, and bent terminals can cause problems (no electrical contact = anopen).

1. Connect one lead of the lest light to a known good ground, or, if you're using a digital volt ohmmeter (DVOM), place it in the appropriate DC
volts range, and connect its negative lead to ground.

2. Connect the other lead of the test light or DVOM to the point you want to check.3. If the test light glows, there is voltage present. If you're using a DVOM, note the voltage reading. It should be within of measured batteryone volt
voltage. A loss of more than indicates a problem.one volt

Always use a DVOM on high impedance circuits. A test light may not glow (even with battery voltage present).NOTE:

Testing For Voltage Drop

one volt

Wires, connectors, and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than indicates aproblem.

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

2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch).3. Turn on the components in the circuit.4. The DVOM will show the difference in voltage between the two points. A difference, or drop, of more than indicates a problem. Checkone volt
