(3) The part of the part of the part of the part is a diagram of the installation position of the automotive power equipment parts. The automotive power equipment is marked according to the system to facilitate maintenance and detection. Especially the location of the engine sensor and a actuator is often used during maintenance .
parts location diagram
(4) The so -called wiring diagram refers to the instruction diagram specifically used to mark the installation location, appearance, and line direction of electrical equipment. It is drawn according to the actual orientation of the installation of the entire vehicle electrical equipment, and the connection between the components and the components is drawn according to the actual relationship. In order to get closer to the actual situation as possible, the electrical appliances in the figure do not use graphic symbols, but use the outline or features of the electrical appliances. In the figure, you should also pay attention to draw the wires in the same road in the wiring beam as much as possible.
The car wiring diagram clearly reflects the actual line conditions of the car. When checking the line, the branches and contacts in the middle of the wire are easy to find, which

3.1.2 The characteristics of the circuit schematic diagram

① The circuit schematic diagram is not only a complete full -vehicle circuit diagram, but also an interconnected local circuit diagram. The content is detailed and simple.

② In order to better express the working principle and interconnection of the car, the vehicle circuit is drawn together according to the association to become the entire vehicle circuit diagram, and the separate system extraction is extracted and drawn into a local circuit diagram in specific use.

③ In the circuit schematic diagram, use electrical symbols to express various electrical components. See Table 3-1-1.

④ The concept of potential height is established on the circuit schematic diagram. The negative electrode iron potential is the lowest, and the bottom wire in the figure is represented by the bottom wire; the positive connection wire potential is the highest, and the top wire is represented.

⑤ The direction of the current is basically from top to bottom.

⑥ Each electrical appliances no longer follow the installation location of the electrical appliances on the vehicle, but in accordance with the working principle, the reasonable layout in the figure makes each system in a relatively independent position, so that it is easy to perform separate circuit analysis of each electric equipment (picture 3-1-6).

The names and code of electrical appliances are usually marked next to each electrical appliance (such as control devices, relays, overload protection devices, electrical appliances and iron points, etc.).

⑧ All switches and electrical appliances in the circuit principle diagram are not working. For example, the ignition switch is disconnected, the engine does not work, the lights are turned off, etc.

The wire of the circuit diagram is generally marked with color and specifications. Some models also marked the code of the electrical system of the wire. According to the above label, it is easy to find the position of the electrical appliance or wire on the car in the control position.
