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. Furthermore, to aid in understanding electrical (electronic) operation, wiring inside complicated components has been simplified.

Current Flow (1) Each cell normally starts with the component that powers the circuit, such as a fuse or the ignition switch. Current flow is shown from the power source at the top of the page to ground at the bottom of the page. In order to concentrate on the essential parts, power supply and ground connections are sometimes simplified by a dashed line in the schematics. A full representation of the power supply of a fuse or the power distribution from a fuse to various components is given in cell 13 “Power Distribution”. Full representation of the ground connections are shown in cell 10 “Grounds”. Switch Positions (2) Within the schematic, all switches, sensors and relays are shown “at rest” (as if the Ignition Switch were OFF). Splices (3) A dashed line indicates that the splice is not shown completely. A reference is given to the page where the splice appears in full. It is also listed in the Index.

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. The page where the component appears in full is listed in the Index. The base part number for a component is listed in parentheses next to or under a component. These part numbers will appear any place the component name appears in the publication. Internal Name and Function Identification Numbers (6) Some components on each page have internal symbols with an identification number located to the right. You can identify the internal symbol or function by finding the corresponding number under the component name. Circuit Function Identifiers (7) Some components without internal schematics use symbols or text to describe the function of a circuit in a system.

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. Cell 150 “Connector Views” show the views of the pins and/or cavities of all connectors. The pin and cavity sides are shown separately as if the connector were disconnected. The color of the connector housing is indicated next to the connector number when available. The harness causal number is located above the component name and below the connector number or above the connector face itself. Wiring harness designations are listed in cell 152 “Component Location Charts”. Circuit function charts are located below each connector.

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. D Keep away from moving parts, especially the fan and belts, when the engine is running. D To prevent serious burns, avoid contact with hot metal parts such as the radiator, exhaust manifold, tail pipe, catalytic converter and muffler. D Do not allow flame or sparks near the battery. Gases are always present in and around the battery cell. An explosion could occur. D Do not smoke when working on a vehicle. D To avoid injury, always remove rings, watches, loose hanging jewelry and avoid wearing loose clothing.

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. If those terminals need to be replaced, they must be replaced with a gold plated terminal. Terminal not properly seated 1 = Locked terminal 2 = Male half 3 = Female half 4 = Seal 5 = Intermittent contact 6 = Unlocked terminal (Hidden by wire seal) 7 = Seal Check for unlocked terminals by pulling each wire at the end of the connector.

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. Using the proper crimping tool for the splice, hand crimp the wires and splice. 7. Gently tug on the wires to be sure they are secure. 8. Electrically check the circuit for continuity through the splice.

9. Evenly position supplied heat shrink tubing over wire repair. 10. Use shielded heat gun to heat the repaired area until adhesive flows out of both ends of the heat shrink tubing. 11. Reconnect battery ground cable.

5R110 Transmission The intermediate (SSPC−C), low/reverse (SSPC−E), and overdrive (SSPC−B) clutches are each controlled by a directly proportional Variable Force Shift (VFS) solenoid. The coast (SSPC−A) and direct (SSPC−D) clutches are each controlled by an inversely proportional VFS solenoid. All shift pressure solenoids are electronically controlled by the PCM, which varies the current from 0 to 1 amp (directly proportional) or 1 to 0 amp (inversely proportional).

The Torque Converter Clutch (TCC) solenoid is a directly proportional Variable Force Shift (VFS) solenoid. The pressure output of this three−port device is proportional to the applied DC current supplied through an electronically controlled driver which varies the current from the PCM between 0 and 1 amp.

The Transmission Range (TR−P) sensor assembly is an internally mounted sensor, located next to the solenoid body, and includes the detent spring, rooster comb, and bracket. The sensor is non−adjustable and is serviced as an assembly. The sensor contains electronic circuitry that provides the PCM a fixed frequency at a duty cycle for each of the various positions of the manual lever (Park, Reverse, Neutral, etc.). The PCM uses the sensor signal for engine functions (start, reversing lamps) and for line pressure control, shift scheduling, and TCC operation.
