Pressure Regulating Solenoid: Diagram Information and Instructions
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 diagram 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 diagram from one which is only a few inches long. Furthermore, to aid in understanding electrical (electronic) operation, wiring
inside complicated components has been simplified.
Complete Circuit Operation
Each circuit is shown completely and independently in one set of diagrams. Other components which are connected to the circuit may not be shown
unless they influence the circuit operation.
Current Flow (1)
Each set of diagrams 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 diagram to ground at the bottom of the diagram. A full representation of the power supply of a fuse or the power
distribution from a fuse to various components is given in Power and Ground Distribution Diagrams. Full representation of the ground connections
are shown in Power and Ground Distribution Diagrams.
Switch Positions (2)
Within the diagram, all switches, sensors and relays are shown "at rest" (as if the Ignition Switch were OFF).
Splices (3)
Splices directly connecting to the power distribution are best represented on the power distribution diagrams in Power and Ground Distribution
Diagrams. Splices connected to grounds can be seen completely in Power and Ground Distribution Diagrams. For all other splices, a reference is given
to the diagram where that particular splice can be best viewed.
Component Referencing (4)
The Power Distribution components and ground components on a diagram have a reference to a component location view or the diagram where it is
shown completely. All other components have a reference to a component location view only.
It is located to the right of each component.
Component Names (5)
Component names are placed on the right hand side of each component when possible. Descriptions of the internals of the component are also
included when available. The diagram where the component appears in full is listed in the Vehicle/Locations. The base part number for a component
is listed in Vehicle/Diagrams.
Internal Name and Function Identification Numbers (6)
Some components on each diagram have internal symbols with an identification number located within it. You can identify the internal symbol or
