Table 7. For added safety, the model was supplemented with a brake signal and rear lighting. Thanks to different engines, the VAZ engine compartment wiring has its own design differences: the VAZ model has larger wiring harnesses due to the installation of additional sensors and electronic devices; The connectors of some electrical circuits have also changed; The layout of some of the wires has changed.


In addition, the layout of some of the electrical components as a whole was changed. On cars with an injection engine there is an additional unit located in the front passenger's feet.


When the lock socket illumination is on and the engine is running, the anti-theft locking device blocks the VAZ starter from re-engaging. The luggage compartment has become more spacious and convenient due to the increase in the trunk lid.

Summary electrical diagram of VAZ 2115 injector 8 valves

Modifications

The VAZ 2115 manufacturer offers consumers a choice of several configurations, on which their cost depends:

  1. One and a half liter carburetor engine. In this case, the car is marked as VAZ 2115-01.
  2. An engine with the same volume, characterized by the presence of a distributor fuel injection system. In addition, the car is also equipped with electronic control and is labeled as VAZ 2115-20.


Dimensions of the “fifteenth” Lada

Car electrical equipment

VAZ 2115 injectors or carburetors use a single-wire electrical circuit. In this case, the negative terminal of the power supplies is connected to the minus, and the positive terminal itself is supplied with a separate wire.

As a result of the fact that the VAZ 2115 carburetor and injector have certain differences, there is also a difference in the design features of the wiring:

  1. In injection versions, the wiring harnesses are slightly larger in size as a result of the fact that the system is equipped with additional regulators and other electrical equipment.
  2. As a result of the change in the circuit, changes were made to the design of some electrical circuits.
  3. In addition, the layout of some of the electrical components as a whole was changed.


Wiring diagram on the “fifteenth” Lada
On VAZ 2115 cars, as on its predecessors, the process of repairing the electrical wiring diagram and equipment usually leads to damage to the fixing clips. In any case, if these elements are damaged, they must be replaced, otherwise the electrical wiring may be very close to the hot motor, which will damage it.

Machine electrical protection

The electrical circuit, in particular, the power circuits in these car models are protected from various damages using fuses. The cost of these elements in stores is minimal, but they play a very important role and must always be in working order.

Fuses do not protect only:

  • car battery charging diagram;
  • ignition circuit;
  • electrical circuit for powering the generator and starter.

Electrical equipment is protected by a block in which all fuses are collected, and this block is located in the engine compartment. Electrical equipment such as a starter, windshield wipers, as well as optics are connected to the general circuit via a relay. The relay is also installed in the block. In general, the electrical circuit of the wiper motor and optics is protected by bimetallic reusable elements.


Injector relay block

So, how is electrical equipment protected on domestic cars:

  • fuses on the block, which are designed to protect various elements of equipment, are marked as F1-F20;
  • K1 is a device that protects the optical cleaner circuit;
  • K2 - is responsible for the functionality of the light alarm, as well as turn signals;
  • K3 - the element ensures the functionality of the windshield wipers;
  • K4 - the device protects the electrical circuit of optics, in particular, incandescent light bulbs;
  • K5 - if the car is equipped with electric window regulators, then this relay is responsible for their performance;
  • K6 - car steering horn;
  • K7 — rear window heating system device;
  • K8 - long-range vehicle lighting;
  • K9 - low-beam vehicle lighting.

It should be noted that the lamps for the fog lights in the rear headlights are protected separately. For this purpose, a fuse is used, installed in the vehicle interior under the center console. It is located in the wiring harness, next to the optics power button.

Removal instructions

If you don’t know how to remove the window lifter handle, don’t despair, it’s easy to do. Before removing the mechanism, you need to remove the trim from the door. Then be sure to disconnect the wire block and the power window connector. Then remove the three nuts that secure the mechanism to the door. Next are two bolts that secure the lift and the glass itself.


Dismantling process

Then, lift the glass to the very top and fix it, you can use a screwdriver or ask someone to hold it. But it’s better to pull it out, because otherwise there is a risk that the glass may break.

To completely remove the mechanism, you need to additionally remove the door handle. To do this, unscrew its two screws and push the handle inside the door. Then, you will need to disconnect the rubber holder that holds the rod on the handle. Once you're done with this, you can pull out the handle, and then the window regulator itself through the same hole. Now you know how to remove the window handle and the entire mechanism.

Lada 2115 › Logbook › ESP buttons in a modern way

For many owners of VAZ cars, any breakdown requires tuning. I'm not an exception. One unfortunate morning, the power window button on the driver's door let me down. I opened the window a little, and when I tried to close it...click, click...the button ran out. I had to swap places with the one that is responsible for the operation of the ESP of the passenger door. I didn’t put it on the back burner; after an honest week of work, I made it to the garage. I knew for sure that there was such a button there. I quickly found it...

This is interesting: Lighting candles on Shabbat today in Moscow

... and I also found 2 buttons like this.

As far as I know, these are on all doors except the driver's in Kalinas and Priors. I knew about their existence in the garage for a long time, but did not pay due attention. But it was necessary. The connector is exactly the same as on the Samar buttons. What do you think was my train of thought)))... Of course, it was decided to put “fashionable” and modern ones instead of native ones. The place to install new ones is the armrests on the doors. But there are only 2 buttons, and you need 3, and how can you fit them into the driver’s side... If 2 are next to each other, then the buttons themselves need to be cut, and oh, how I didn’t want that. And it won't turn out very nice. Chasing such thoughts in my head, I went to the store to get the 3rd button. The store found a solution to the problem. Here it is

These are paired buttons from the Grant fret, they also have exactly the same connectors as on the Samar buttons. While the price of a separate button is 140 rubles, this one costs 190 rubles, the difference is not big at all, but I got what I wanted. Plus one button remains in garage supplies))). I also purchased plugs for the standard holes on the doors. Half the job is done, all that remains is installation. I removed the door trims and immediately dug out the old pistons that held them in place. Then I used a marker, a knife and the golden rule: measure 7 times, cut once. The buttons sat straight and tight. The wiring on the driver's door did not create any problems, but the wiring on the passenger door had to be increased. There was literally 3-4 cm missing. You could, of course, tighten it, but what if something breaks or frays over time. I would like all the improvements to be reliable and I would patiently build up the missing wires, insulating everything with heat shrink. Now everything is in reserve, it doesn’t pull or rub anywhere. The casings fell into place safely, instead of the original buttons I installed the purchased plugs, but the new pistons failed and I had to go to the store again. There I bought a good alternative for them and everything fit tightly and reliably the first time. This “alternative” is discussed separately in my blog. And here are photos of the finished result:

Operating principle

A fan is a device that allows you to increase the efficiency of a cooling radiator. The radiator takes heat from the engine and releases it into the air. This process is accelerated by blowing through the blades of an electric fan.

The coolant flows through a closed, sealed system. Its task is to remove excess heat from overheated engine parts. Hot antifreeze flows into the radiator, is cooled here and returns back. While in the radiator, the coolant passes through a system of thin tubes. The incoming air flow while the car is moving helps to quickly remove excess heat from the engine compartment.

But when the car is stuck in traffic or idling, the air flow stops cooling it. In this case, the cooling system may not cope with its task. An electric radiator fan is designed to create air flow artificially. The temperature for turning on the fan on a VAZ 2114 is 85 degrees Celsius.

Differences from its predecessor

The VAZ 2115 car is a more modernized version of model 21099. The improvement of the “ninety-nine” contributed to the updating of the electrical wiring diagram.

It should be noted that, unlike 21099, the VAZ 2115 injector is equipped with newer body parts, in particular, we are talking about:

  • improved shape of the front wings;
  • the appearance of the headlights;
  • back panel shape;
  • different shape of the hood and luggage compartment.


Toy models VAZ 21099 and VAZ 2115
Of course, the changes also affected the engine compartment. Compared to 21099, the VAZ 2115 is equipped with a more powerful engine. Changes also affected the interior - a more advanced center console, instrument panel, and seats. An on-board computer was also added to the design of the car. Accordingly, the overall dimensions of the VAZ 2115 also underwent changes. But in general, this car remained the same - a front-wheel drive, five-door and five-seater sedan.

When 12V voltage is applied to terminals “B” and ground, the light bulb should light up. When a voltage of 15-16V is applied to terminals “B” and ground, the light bulb should not light up. If the light bulb lights up in two cases, then there is a breakdown in the regulator. If it does not light up, there are two options: there is a break in the regulator or there is no contact between the brushes and the terminals of the regulator.

Electrical wiring system maintenance

To ensure the functionality of the electrical system, it is necessary to regularly check and diagnose the components:

  1. If problems are detected in operation (even minimal malfunctions), the condition of the connecting plugs should be analyzed.
  2. Often, after the owner moves the pad, contact is restored. Further use of such elements is not recommended.
  3. The unit needs to be replaced with a similar one, while simultaneously finding out the cause of oxidation of the old parts.

Relay contacts are prone to burning when exposed to high current. The devices can be removed from the unit and the condition of the conductive contacts can be inspected.

This requires:

  1. Remove the plastic protective cover.
  2. Carefully clean the burnt contacts with fine sandpaper and blow with air.

If there is significant wear on parts, it is necessary to install new relays.

Due to the location of the installation box in the air supply channel, it becomes clogged with dust and is exposed to moisture. Over time, this leads to the destruction of the conductive paths on the printed circuit boards and loss of contact. The unit should be inspected once a year; if defects are found, it is recommended to replace it with a new one. At the same time, it is necessary to monitor the condition of the grounding wire, which can oxidize at the connection points.

For correct operation of consumers, it is necessary to check the condition of voltage sources. The battery should be periodically recharged from a stationary device. Charging the battery and the functioning of the electrical circuit while driving depends on the tension and condition of the generator rotor drive belt. When the commutator and brushes wear out, the operation of the generator is disrupted, which leads to the car losing power.

Here is an electrical diagram of the internal connections of the mounting block of fuses and relays of the VAZ 2114-3722.010 brand. It shows relays connecting the main consumers of electricity. These relays are presented with their own internal electrical circuits, providing the opportunity for a better understanding of the operation of this device. This diagram shows plug blocks on both sides with their numbers and the numbers of the terminal connectors. Internal number - indicates the number of the terminal connector. The external designation in the form “Ш1”, “Ш2” and so on is the designation of plug connectors.

Close the starter from the pushrod

Before starting the car directly through the starter, you should find out why the starter failed.

If the reason is a malfunction of the relay, solenoid relay, or starter winding, then you can start it from the pusher.

For this you will need a couple of assistants. They will rest against the trunk of the car and accelerate it, and you turn on the ignition key and first gear. The faster the assistants push the car, the faster it will start.

Did you know?
Acceleration from a pusher is the most popular method of starting a car without a starter among car enthusiasts.
