Basic and additional diagrams of the VAZ 2109 passenger car

This article contains a color general diagram of a VAZ 2109 passenger car. For a better understanding of how to connect individual electrical devices and circuits to the overall diagram, additional electrical diagrams of these devices are presented on this page. All electrical diagrams have explanations and explanations of the designation points. At the beginning of the article there is a table of modifications of the VAZ 2109 car produced by the Volga Automobile Plant for domestic and foreign markets. It supplements information about the electrical devices of this vehicle. For additional information about the design of electrical systems, equipment and circuits of the VAZ 2109 passenger car and its modifications, there is a section of special technical literature on this page. There you can view and download the necessary catalogs and manuals for the repair and operation of these vehicles.

Generator Differences

It was already mentioned earlier that the wiring diagram of the VAZ 21213 had some differences, primarily related to the installed power unit.

In particular, fuel-injected versions required a more powerful generator, so:

• A generator model 371.3701 was installed on the VAZ 21213;
• The VAZ 21214 was equipped with generator model 9412.3701.

They are structurally similar and are synchronous AC machines with a built-in rectifier and output voltage regulator.

Wiring Differences

The VAZ 21213 engine compartment wiring is made in different designs to facilitate do-it-yourself maintenance.

For versions with an injection power unit, the wiring on the VAZ 21213 has three additional connectors for the contactless ignition unit.

In addition, the VAZ 21214 model has 2 radiator cooling fans, so the wiring for them also has its differences from the “thirteenth”. A schematic diagram of connecting the elements of the cooling system is presented below.

How to read car electrical diagrams - basic symbols

In order to understand the principle of operation of a device, a knowledgeable person will only need to look at the electrical diagram. Let's look at the main nuances that will help even a beginner understand the circuits. It is clear that not a single device will operate without current, which is supplied through internal conductors. These routes are indicated by thin lines, and their color should match the actual color of the wires.

If the electrical circuit consists of a large number of elements, then the route on it is depicted with segments and breaks, and the places of their connections or connections must be indicated.

The numbers indicated on the nodes must correspond to real numbers. The numbers in the circles show the connections of the wires with a “minus”, and the designation of current-carrying paths makes it easier to find elements located on various circuits. Combinations of numbers and letters correspond to detachable connections. There are special tables that make it very easy to identify elements of electrical circuits. They are very easy to find both on the Internet and in manuals for specialists. In general, car electrical diagrams are quite easy to read; the main thing is to understand the functionality of their elements and follow the numbers.

When reading the electrical diagram, you should consider some features:

What are car wiring diagrams?

What devices and elements does the vehicle's electrical wiring and electrical equipment system include? A schematic electrical diagram is a visual representation where all the icons of the components used are indicated without exception. All devices are located in a specific order on the diagram, and they can be connected to each other in either a serial or parallel manner. It must be taken into account that the electrical diagram of a car or truck itself does not actually show the actual location of the equipment. It only shows how all consumers and energy sources are connected.

Regardless of the machine, the circuit includes the following components:

Why understand electrical circuits?

Being able to read such diagrams is quite important for anyone who owns a car, because it will help save a lot of money on the services of a specialist. Of course, fixing any serious breakdowns on your own without the participation of professionals is difficult, and even fraught, because the current does not tolerate mistakes. However, if we are talking about some basic malfunction or you need to connect the battery, ECU, headlights, side lights, etc., then doing it yourself is quite possible.

In addition, we often want to add additional electronic devices into the circuit, such as an alarm system, a radio, or a car air conditioner, which greatly facilitate the driving process and fill our lives with comfort. And here you cannot do without the ability to understand electrical circuits, because they are often included with all of the listed devices. This is also relevant for owners of cars with a trailer, as sometimes problems arise with its connection. And then you will need a wiring diagram for a passenger car trailer and, naturally, the skills to understand it.

Standard elements of a car circuit diagram

Let us finally begin to examine the elements of the diagram and learn how to read it.

Standard power circuits and connection of elements

Power circuits - circuit elements that transmit current, are depicted by lines: at the top of the diagram there are circuits with a positive potential (“plus” of the battery), and at the bottom - with a zero potential, i.e. ground (or battery negative).

Circuit 30 - comes from the positive terminal of the battery, 15 - from the battery through the ignition switch - “Ignition 1” Circuit number 31 - grounding

Some wires also have a digital designation at the point of connection to the device; this digital designation allows you to determine where it comes from without tracing the circuit. These designations are combined in the DIN 72552 (frequently used values):

For convenience, connections between elements on color diagrams are depicted in different colors corresponding to the colors of the wires, and on some diagrams the wire cross-section is also indicated. On black and white diagrams, the colors of the connections are indicated by letters:

Sometimes you can find an empty circle in a node - this means that this connection depends on the configuration of the car, and the lines are usually signed.

Designation of connectors on the electrical diagram - connectors

Wires in car wiring are connected in several ways, and one of them is connectors. The connectors are designated by the letter “C” and a serial number. In the figure on the left you see a schematic representation of the connections of sections of wire through connectors. In general, it is more correct to say not “pin No. 2”, but “terminal No. 2”; if you come across such a concept in the diagram, then now you will know that this is the serial number of the connection (contact) in the connector.

What opportunities open up for a car owner who understands the circuits?

Every car owner should understand the auto electrical circuit, since if problems arise in the operation of the equipment, you can deal with the breakdown yourself. Naturally, if more complex problems occur in the operation of the network and equipment, then it is unlikely that you will be able to identify them yourself without experience. Especially when you consider that modern cars use more complex circuits, which is associated with the use of a larger number of various devices.

Also, the need to understand the operation of a particular circuit for a car may arise for those car owners who want to make adjustments to the operation of the system. For example, if you are planning to improve and tune your vehicle, this does not necessarily mean using upgraded body kits or bumpers. If the interior is being tuned, the car owner can install a new audio system or air conditioner, in which case it is impossible to do without making changes. In addition, you need to understand the operation of the circuit even if you decide to install an anti-theft installation yourself.

Those motorists who periodically use a trailer should also be able to understand the circuit, since our compatriots often face connection problems. One way or another, if you want to install additional devices and add their system, then understanding the electrical circuit is simply necessary.
