VAZ 2110 2111 2112 (injector) fuses and relays

VAZ 2110 2111 2112 (Lada 110 111 112) - a family of cars produced in 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 and 2009 with sedan and hatchback bodies and a station wagon mainly with 8 and 16 valve gasoline engines ( injector , carburetor). In this article you will find a description of the fuse and relay blocks of the VAZ 2110 2111 2112 with diagrams , photographs and their locations. Electrical connection diagram. Let's highlight the fuse responsible for the cigarette lighter.

The purpose of fuses and relays in your VAZ 2110 (2111 / 2112) relay may differ from those presented and depend on the year of manufacture. The current purpose can be printed on the block itself.

Relays - what they are, what they are responsible for

Cooling fan activation sensor in carburetor cars

If the “ten” is equipped with a carburetor-type engine, then to perform the function of warning about overheating of the power plant, a TM-108 thermobimetallic type cooling fan switching sensor is used, while in VAZ 2110 injectors these functions are assigned to the controller.

If the fan installation is “commanded” by the fan switching sensor, then its initiation is directly related to the temperature setting of this device. This information can be obtained by reading the labels on the product body.

When the temperature reaches critical values, the fan switch sensor must initiate operation of the fan unit. If this does not happen, you should look not only where the fan switch sensor is located, but also the malfunction of this control device.

The test for the functionality of the device is quite simple - you just need to short-circuit the contacts of the device and, if the fan unit works when it starts, then you need to replace the fan switch sensor with a working element.

If during this test the fan device does not turn on, then it is necessary to check the suitability of the fuse for further use and the serviceability of the supply wiring.

Fuses - what they are responsible for, which ones to buy

Basic starter malfunctions

The traction relay does not operate after the ignition key has been turned, and the armature does not rotate.

In this situation, it may be due to the following possible problems:

• the battery is broken or discharged, the solution to this problem is to buy a new battery or charge it;
• the positive contacts have oxidized - you just need to clean them;
• it happens that an interturn short circuit occurs on the winding of the traction relay - to correct this situation, you need to install a new relay;
• the circuit that powers the traction relay has broken - you need to check the wires for integrity, and whether they have become disconnected from the circuit?
• contacts “30” and “50” do not close - you just need to change the contact part of the ignition switch;
• The traction relay armature does not work well - you need to remove it and disassemble it, there may be a lubrication problem.

After turning the key, the starter does not start, the armature rotates slowly, and a click is heard in the traction relay.

This situation may arise due to previously similar situations:

• the battery is discharged or disconnected - you need to check and correct the situation;
• the winding of the traction relay is shorted or broken - you also just need to change the relay;
• the ends of the wires have seriously succumbed to oxidation - they need to be checked and cleaned, starting with the battery.

After turning the key, the starter armature spins, but the flywheel does not spin..

This situation arose due to the fact that:

• the freewheel is slipping - you need to diagnose the starter at the stand and replace the clutch if it is faulty;
• The gears on the gearbox are worn out - you just need to replace them.

The starter makes a lot of noise when the armature is spinning.

This problem arose because:

• The liners on the armature or drive shaft bearings have served their service life - you just need to replace the parts that have failed;
• the starter is not secured properly, and the cover could have broken - you just need to secure it or change it;
• the gears on the gearbox, flywheel crown or drive have failed - you just need to change them, or immediately replace the non-functioning parts entirely.
• the gear is constantly engaged with the flywheel; if the clutch on the shaft splines is stuck, it is possible that the armature of the traction relay is stuck - to solve this problem, you need to lubricate the splines with oil. And if the traction relay is stuck, then you need to either change it or use certain methods to get rid of the jam.

Removing and installing the fuse box

Disconnect the wire from the “–” terminal of the battery.

Open the cover of the mounting block and unscrew the screw securing it.

Pull the block towards you.

Disconnect the blocks with wires from the unit (it is recommended to tie these wires with insulating tape into a bundle).

Remove the unit cover by unscrewing the two screws securing the hinge brackets.

How to check the fan switch sensor using a multimeter?

To check, you will need water, an empty container, a thermometer and a heat source (gas or electric stove). Checking the fan switch sensor is no different from.

• The principle is as follows: you need to pour water into the container.
• Lower the threaded part of the DVV there.
• Connect the multimeter terminals to the sensor contacts and turn the device into resistance measurement mode, or into “continuity” mode.
• Now gradually heat the water.
• After the water temperature reaches ~92°, the contacts of the working fan switch sensor should close, after which the multimeter should make a sound.

If you are convinced that the sensor is faulty, replace the sensor.

What to do if they cannot determine the reason why the car does not start?

Attention. We advise you, fellow motorists, to initially, for electronic diagnostics of your car, immediately contact specialized dealership auto centers that service only your or your particular brand of car (office dealer and others). Only they can guarantee you a professional approach to diagnostics and classified repairs of your vehicle.

Typically, such car services have a full range of electronic equipment and expensive software for car diagnostics. Indeed, in ordinary services and in the same garages, despite the high classification of some certain specialists, there is often no highly specialized expensive equipment and software that is necessary for quick troubleshooting.

For example, the cost of some specific software intended for diagnostic equipment can cost several hundred thousand US dollars. (!) Unfortunately, most car services (especially garage technicians) cannot afford to purchase such “autosoftware” for themselves. It is too expensive.

Circuits protected by additional fuses (all fuses on A) on the VAZ-2110:

Additional fuses: 1 – ignition module, controller; 2 – canister purge valve, vehicle speed sensor, oxygen (heating) sensor, air flow sensor; 3 – fuel pump relay, fuel pump, injectors.

Additional relays: 4 – electric fan relay; 5 – electric fuel pump relay; 6 – main relay (ignition relay).

There is a fog lamp fuse installed in the niche of the instrument panel behind the mounting block:

Reason No. 2 - when the engine doesn’t purr-murr

There are also more difficult situations. When you turn the key in the ignition, and there is no purr-purr in response, complete silence. In the vast majority of cases, the culprit for this breakdown will be a dead battery. If you have a car battery charger, you will have to take the battery home to charge. When there is no such charger, you will have to seek the help of another driver who has wires with him for “lighting up”. It is best to replace a battery that has started to feel so bad with a new one in order to save yourself from sudden problems. It also happens that the battery is charged, but the car still refuses to start. In this case, the starter is to blame and will most likely need a relay replacement.

Other reasons why the car won't start.

Having thus checked all the main car systems that could affect the car’s engine starting, you, dear motorists, should know that there are still a number of specific tips that you can resort to and perform them yourself to find out why your car does not start. If you have patience and time to do this kind of troubleshooting, you can do the following yourself:

— Loose starter mounts: Sometimes the starter mounts become loose, which can cause a lack of ignition.

— Bad injectors: A malfunctioning injector affects the entire fuel system, which can cause the engine to fail to start. Especially when starting when the engine is still warm.

— Faulty starting valve: If this part of the car is in a faulty condition, then when starting the engine (especially in cold weather), a malfunction may occur and the car simply will not start. This faulty valve can also cause uneven operation of the engine after it warms up.

— Chips on the flywheel: The starter not only ignites the car, but also transmits torque to the flywheel, which is connected to the transmission. If the flywheel teeth are chipped or damaged, when the starter rotates, you can hear a characteristic sound (squealing, creaking) produced by the flywheel itself which has a defect. It is noteworthy that a similar problem can also be the reason for the engine failure to start.

— Immobilizer or Engine Control Unit (ECU) malfunction: If your vehicle's main computer malfunctions, it can significantly affect the performance of the ignition system itself and fuel injection. Including, if any electronic system malfunctions, then in many modern cars the engine management system can simply block the engine from starting itself. Also, a common reason for failure to start the engine is a specific malfunction in the electronic anti-theft system (immobilizer).

When it breaks down, as a rule, this electronic unit simply does not recognize your key, which contains a chip with an electronic code that disables the security system.

Unfortunately for us, you simply cannot check all these electronic systems yourself, since expensive equipment is needed to diagnose the electronics of the machine.

Ignition

So, if everything listed above is in good condition, check the ignition. First you need to test the ignition coil. It is checked with a multimeter. If such a device is not available, then you can stop by the nearest car service center.

It happens that moisture accumulates in the ignition distribution cover, this can cause the engine to not start. The cover must be removed and checked for moisture. Any moisture or condensation that appears must be removed with a dry cloth. Since you had to remove the cover, you should check it for cracks. A cracked lid should be replaced with a new one.

The wires on the ignition coil may be damaged or leaking electrical current. Place the tester near the wire insulation. Functional wires will not conduct current through the insulation. If the tester shows that the wires are faulty, you will have to buy new ones.

Spark plug

Spark plugs are designed to ignite fuel-air mixtures. They come in different types: spark, incandescent, semiconductor and others. If your car does not start, then turning the starter for a long time will lead to flooding of the spark plugs. After which they will need to be changed. Otherwise, working with flooded spark plugs will harm other parts of your car.

Electrical problems starting the engine.

— Check the fuses: Few modern car models have a fuse in their system that is directly related to starting the engine. But still, before examining other components and assemblies of the car, you must first check the fuses themselves for operability.

— Corrosion of battery terminals and cables: Over time, battery connections can become dirty or corroded. Dirt or corrosion breaks the secure connection between the terminals and the battery. As a result of such poor conductivity of electric current, the car may simply not start. Try, friends, to clean the battery terminals and the high-voltage wire connectors themselves, and then try to start the car again.

— Discharged battery: The most common reason why a car will not start is a discharged battery. If you have a special tester for checking battery charging, be sure to check it for charging capacity. If you do not have this special device for measuring battery charging, then you can determine the battery discharge using or using indirect signs.

For example, if from the first start of the engine you hear that the starter in the car is spinning very slowly, then the reason for the failure to start the engine will probably be a discharged battery. In order to start the car in this case, you just need to charge the battery using a special charger. Please remember that if the battery life has expired, then charging the battery even using the charger itself will not help you, since the special battery plates in this case simply do not hold a charge. In this case, you will still have to purchase a new battery for the car.

— Faulty ignition switch: If the battery and high-voltage wires in your car are fine, but you still cannot start the car, then it is likely that the cause of the failure may be a faulty ignition switch. In order to check the serviceability of this component of the car, please insert the key into the ignition switch and turn it, but not all the way (turning on the dashboard). If, after turning the key to the first or second position (depending on the make and model of the vehicle), the red signal icons on the instrument panel do not light up, then most likely the ignition switch in the car is faulty.

If the red instrument lights come on, turn the key to the engine start position. In this position, the red warning lights should go out (in most car models). Another way to check the functionality of the ignition switch. Turn on the low beam headlights and try to start the engine. If at this moment the headlights become very dim or go out completely, then the ignition switch on your vehicle is in working condition. Otherwise, the switch on the machine simply needs to be replaced.

— Starter failure: Corrosion can damage not only the battery itself, it can also affect any electrical component of the vehicle. For example, even the starter can fail in a car under the influence of atmospheric conditions. In order to check the functionality of the starter, you need an assistant. For this check, you need a regular tester that measures electric current. Connect your tester to the wire that powers the starter. Have a helper turn the ignition key to start the engine. If, when the engine starts, the tester shows that electric current is supplied to the starter, but it still does not rotate, then it is necessary to replace the faulty starter with a new one.

Attention. When connecting the electrical tester to the starter wire, be very careful as your hands are near moving engine parts that could cause personal injury.

If the starter spins in the car, then the reason for the failure to start the engine is something else. In order to still find the fault, you need to check other parts and components of the car.

Friends, we continue to search for the reason for the failure to start the engine in order to answer the question - “ Why doesn’t the engine start? ".

Another reason why the power unit does not start may be a simple lack of ignition spark. But don’t tell your friends to immediately rush to check the spark plugs. First, you need to check the ignition coil itself, and check the spark plugs themselves last, after the final diagnosis of other components and parts of the car, which could be the specific cause of the ignition problem.

Reason number 1 - no gasoline or spark

Don’t rush to call a tow truck and take your car to a service center. First, you can try to identify and fix the problem yourself. You should start by checking whether there is gasoline in the car. In your daily worries, you can easily forget about gas stations and not pay attention to the warning lights on the dashboard. If there is gasoline and the fuel pump hums when you turn on the ignition, then we check the spark. We will need an assistant to check.

It is necessary to unscrew the spark plug and put the cap of the high-voltage wire back on it and lean it against the engine body. At this time, the assistant should try to start the car. If there is no spark between the spark plug and the engine, then the problem has been found. Most likely, you need to replace the ignition coil and the car will start normally again.

Fuel system.

If the starter in the car is spinning at full strength and a good spark is observed in the ignition system, then possible problems with starting the engine may be associated with the fuel system.

If your car is equipped with electronic fuel injection, then several of its subsystems may specifically cause the power unit to fail to start.

True, it should be noted here that in most of these cases you simply will not be able to independently diagnose all kinds of electronic systems and subsystems, which may actually be the reason for the failure to start the engine. The point is this: this check requires special diagnostic equipment, which is only available in car service centers or car service dealerships.

True, there are some moments when you can check certain subsystems yourself in a garage. And all this thanks to certain and specific methods of such checking. Although you will not find the specific cause of the breakdown, in any case you will significantly narrow the scope of the search for this malfunction, which will save you a lot of money when you go to a car service for electronic diagnostics of the car.

— Electrical connections: There are many electrical connections in the fuel injection system. Each fuel injector has its own connector on top. There are electrical connectors in the air system of the car, as well as on the cylinder head. You should check all the electrical connectors that are under the hood of the car. This is quite difficult, we understand, but nevertheless, you will save a lot of money on this, which you can then give to a car repair shop without regret .

— Fuel pump and relay: To check the fuel pump you will need special equipment that diagnoses the vehicle's fuel system (pressure). Since most of us motorists do not have this kind of equipment, all we can do ourselves is to completely check all electrical connections .

For example, check the flow of electrical current on the positive wire that powers the fuel pump itself.
To do this you need an electrical tester. Before checking, make sure the ignition key is in the “ On” .
If the tester shows that current is flowing to the pump, then proceed to the next troubleshooting step. If there is no current and does not flow, then you need to check the fuse. If the fuse is in good condition, then the problem with starting the engine is in the fuel pump relay itself. Replace this relay with a new one. — Fuel filter: If the fuel pump is working correctly, this does not mean that fuel is getting into the engine in the normal sufficient quantity. For example, due to this fuel filter, fuel may not flow into the combustion chamber in sufficient quantities, which may cause the power unit to fail to start. In order to avoid such problems, you need to change the fuel filter in your car every 20 thousand kilometers, which can be heavily contaminated with enzyme-forming substances present in the fuel itself .

You can easily check all these elements in the car yourself and, if necessary, replace them yourself, specifically using everyday auto tools. Unfortunately, there are many other fuel electronic systems that simply cannot be checked without the use of special equipment. Therefore, remember, our dear motorists, to do electronic diagnostics of a car, it is best to trust specifically to professionals and contact a car service center.

What to do if the car does not start (the engine does not start)?

What should you do if your car won't start? Maybe try starting the car by pushing it a little? Maybe the battery just died? Or maybe the starter has failed or the key in the ignition is broken? Have you encountered (familiar) with such problems? For many of our car enthusiasts, these are not simple questions to which it is not so easy for them to get answers. Many of them have encountered similar problems more than once and, as luck would have it, at the most inopportune moment. What should you do if your car does not want to start? Firstly, the main thing is to remain calm. We'll fix everything.

If you get into your car and turn the ignition key and do not wait for the engine to start, this can immediately ruin your (any driver’s) mood. The main question that worries all car enthusiasts at this moment is “Why won’t the engine start?”

Unfortunately, it is very difficult and not so easy to establish the reason or reasons why the car refuses to start. After all, there are many reasons that are hidden under the hood of a car due to which the engine may not start. In general, of course, everything that is under the hood can actually and practically be the reason for the failure of the car’s power unit to start.

In order to determine the cause of the engine failure to start, you must first start by checking the battery (the most common reason for the engine failure to start). Only after checking the battery can you move on to other parts of the car and further look for the cause. The main thing here is the consistency of the check itself. This way you will gradually check all the systems in the car that affect the ignition and engine starting.

Some of our tips for testing car units and components due to which the car may not start are not at all complicated and are easy to implement. True, it should be noted that certain recommendations are quite complicated for those motorists who are not at all familiar with the structure of the car and its repair. Nevertheless, friends, most of our advice in this case will still have to be followed in order to find the cause of the engine failure. Thus, if when you turn the key in the ignition switch you do not hear the sound of the engine, we suggest you, friends, do the following:
