3-1 Introduction Note All wiring connections between components are shown exactly as they exist in the vehicles. It is important to realize, however, that no attempt has been made on the schematic to represent components and wiring as they physically appear on the vehicle. For example, a 4-foot length of wire is treated no differently in a schematic from one which is only a few inches long.
Introduction Component Referencing (4) Each component on a schematic has a reference to the component location view or the page where it is shown completely. It is located to the right of each component. Component Names, Notes and Base Part Numbers (5) Component names are placed on the right hand side of each component. Any notes that describe switch positions or operating conditions follow the name. Descriptions of the internals of the component are also included here.
3-3 Introduction Fuse and Relay Information Cell 11 “Fuse and Relay Information” contains a view of the fuse-/relay box in which all fuses and relays are identified. Fuse and Relay Numbering and Naming F1.12 F1.1 F1.13 F1.2 F1.14 F1.3 F1.15 F1.4 F1.23 F1.24 Fuse and relay numbering and naming follow the indication of the fuse panel cover. In addition, a prefix precedes the fuse number to facilitate finding the fuse in the Component Location Charts, e.g. “F1.
Introduction Ground Distribution Cell 10 “Grounds” contains the schematics that show the complete details for each ground connection or main ground splice. This is useful in diagnosing a problem affecting several components at once (poor ground connection or ground splice). All details (wires, splices, connectors) between the ground point and the components are shown. These ground connection details are shown here in order to keep the individual cell schematics as uncluttered as possible.
3-5 Introduction Component and Connector Information Cell 152 “Component Location Charts” helps the user find where the various items depicted on the schematic can physically be found on the vehicle. A brief written description of the location is given, along with a reference to the component location views. Cell 151 “Component Location Views” show the components and their connecting wires as they can be found on the vehicle.
Introduction WARNINGS ! D Always wear safety glasses for eye protection. D Use safety stands whenever a procedure requires being under a vehicle. D Be sure that the Ignition Switch is always in the OFF position, unless otherwise required by the procedure. D Set the parking brake when working on any vehicle. An automatic transmission should be in PARK. A manual transmission should be in NEUTRAL. D Operate the engine only in a well-ventilated area to avoid danger of carbon monoxide.

5-1 Connector Repair Procedures Troubleshooting wiring harness and connector hidden concerns The following illustrations are known examples of wiring harness, splices and connectors that will create intermittent electrical concerns. The concerns are hidden and can only be discovered by a physical evaluation as shown in each illustration. NOTE: Several components, such as the ECM, utilize gold plated terminals in their connections to the wiring harness.
Connector Repair Procedures Defective insulation stripping 1 2 3 4 = = = = Proper crimp Insulation not removed Wire strands missing Intermittent signals through pierced insulation Partially mated connectors 1 = Seal 2 = Displaced tab 3 = Female half 4 = Seal 5 = Intermittent contact 6 = Male half 7 = Intermittent contact Lock may be displaced into an unlocked position; pull on the connector to verify the lock.
5-3 Connector Repair Procedures Deformed (enlarged) female terminals 1 = Enlarged 2 = Normal Any probe entering the terminal may enlarge the contact spring opening creating an intermittent signal. Insert the correct mating terminal (Location A) from the service kit and feel for a loose fit.
Connector Repair Procedures Electrical short within the harness Splice tape removed 1 = Intermittent short Splice covered 2 = 3 = 4 = Wire strand Splice tape Harness tape Broken wire strands in harness 1 = Wiring harness tape 2 = Wiring strand 3 = Broken strands intermittent signal 4 = Circuit insulation Remove the tape and flex/feel each circuit for a reduction in diameter at break.
5-5 Connector Repair Procedures Recommended splicing method − Solder (For 16 AWG and Smaller Diameter Wire Only) 1. Disconnect battery ground cable. 2. Strip wires to appropriate length. 7. Evenly position heat shrink tubing over wire repair. 3. Install heat shrink tubing. 4. Twist wires together. 5. Solder wires together. 8. Use shielded heat gun to heat the repaired area until adhesive flows out of both ends of heat shrink tubing. 9. Reconnect battery ground cable.
Connector Repair Procedures 5-6 Recommended splicing method − Crimp (For 10−22 AWG Diameter Wire to Like Wire Diameter) 1. Disconnect battery ground cable. 2. Remove proper amount of insulation from each wire end, taking care not to nick or cut wire strands. 3. Install heat shrink tubing. 4. Select appropriate wire splice for the wires to be spliced. 5. Install the wire ends into the splice, making sure the ends of the wires are fully inserted. 6.
