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.
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 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, 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 circuit andthen check the Connector View (sample). You find that C324 is common to the rear window defogger circuit and wiper/washer circuit, so youinspect C324 and find the problem, bent terminals.

Circuit Schematics
Each schematic represents one circuit. A circuit's wires and components are arranged to show current flow, from power at the top of the image, toground, 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
Page 12
All in-line, pigtail, and fuse box connectors are numbered (0725, 0416, etc.). Component connectors are not numbered but are identified either by thename of the component if the component only has one connector or by a capital letter (A, B, 0, etc.) if the component has more than one connector.Below most connector numbers and component names are PHOTO and VIEW numbers. The PHOTO number refers to a photo in the connector viewsection of the database. This shows the connector's location on the car. The VIEW number refers to an illustration in the connector view section, thatshows the connector face, wire colors, connector cavity numbers, and other details. The connector cavity numbering sequence begins at the top leftcorner of the connector. Disregard any numbers molded 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 0416, for example, means those terminals join in cavity 2 of connector 0416.
Component Locations
To see where a component or connector is located on the car, look up its photo number in the Component Location section. The photo will also tell youthe color 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.
Connector Views
Page 14
To see the configuration of a connector's cavities, look up its view number in the Connector View section. 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.
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 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.
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. Ifthey 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 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, bent terminals.

Five-Step Troubleshooting
1. Verify The Complaint
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.
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
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.
Troubleshooting Precautions Before Troubleshooting
1. Check the main fuse and the fuse 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, or you will damage the alternator diodes.
- Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring.

While You're Working
1. Make sure connectors are clean, and have no loose terminals or receptacles.
Page 36
2. Make sure that connectors without wire seals are packed with dielectric (silicone) grease. Part Number: 08798-90013. 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.

Most circuits include solid-state devices. Test the voltages in these circuits only with a 1O-megaohm or higher impedance digital multimeter.Never use a test light or analog meter on circuits that contain solid-state devices. Damage to the devices may result.
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.

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 show 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.

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 off, 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 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.
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.
