Useful tips

Author: Anastasia Safonova12/27/201612/27/2016

The VAZ 2110 ignition switch cannot be called a reliable part, especially when you compare its service life with the same devices on cars of foreign origin. Therefore, owners of the tenth - twelfth model, who use the car for a long time, sooner or later encounter problems with the lock and its repair. On the other hand, the element can be easily removed from the car and every skilled motorist can replace it. But first you should figure out whether the entire part needs to be replaced, since in most cases it can be repaired.

Diagnostics and repair

If the ignition switch is broken and the key does not turn, you can try to repair the unit without replacing it. Of course, if this is possible (the author of the video is the Auto Electrician HF channel).

Solving the problem without replacement

First of all, you should diagnose the condition of the node; for this you will need a multimeter. Removing the ignition switch is an individual procedure for each car. Before removing the ignition switch, you need to familiarize yourself with the technical features of this unit specifically in your car in order to prevent possible problems during repairs:

1. First you need to level the steering wheel and disconnect the battery, while the key in the 3Z is turned to position 0.
2. Under the steering wheel there are several bolts that secure the decorative trim of the steering column.
3. Next, the 3Z fixing bolts are unscrewed, after which the key should remain in the installed position. Depending on the vehicle, there may be more fixing bolts, and the overall fastening system may be different. In any case, you need to dismantle the 3Z and disconnect all wires from it. When disconnecting wires, they must be marked so that later during installation there will be no installation problems.
4. After this, when the wire blocks are disconnected, using a tester, you will need to diagnose the serviceability of the terminals in the block.
5. As for repairs, after completing the steps, the ignition switch is disassembled. A device can break down for various reasons, but troubleshooting is always the same. To replace failed elements, the structure must be disassembled; to do this, one of the component parts of the housing is disconnected. By doing this, you will be able to see the failed system components and repair or replace them. When assembling, we must not forget about lubrication - all moving components of the system must be lubricated.

1. Disconnect the wires from the device.
2. Unscrew the screws and dismantle it.

Replacement

Replacing the ignition switch is carried out in the same way - first the unit is removed, then a new one is installed.

How to change the ignition switch yourself:

1. After dismantling, a new device must be installed in place of the old one. If you have marked the wiring, then there will be no problems during installation.
2. There should be markings on the terminal harness so that you can connect the block correctly even if you have not marked it.
3. Once all the cables are connected to the appropriate connectors, the 3Z can be installed in place. In general, there is nothing complicated in installation - you simply repeat all the steps you did during removal, only in reverse order. The ZZ is mounted in the installation location until it stops until a characteristic click is heard, after which the fixing bolts can be tightened. Next, the decorative steering column trim, consisting of two casings, is put in place. At this point, the repair can be considered complete; all you have to do is check the functionality of the protection device.

As a rule, one key is used for the rear lock, trunk and doors. This is because all locks use the same cylinders. So, if the ignition switch is replaced, then in order for the key to work with the trunk and doors, the cylinders in them will also have to be changed. Therefore, repairing a device is always preferable to replacing it. Accordingly, if you change only the ZZ, then the new key will be able to work in tandem with it, and to open the driver's door and trunk you will have to use the old key.

Installation of a new larva

To replace the lock core due to mechanical failure, remove it from the vehicle as described above. Then follow this algorithm:

1. Insert the key into the slot and use a Phillips screwdriver to unscrew the 3 screws holding the 2 halves of the lock body together.
2. Separate the housing while holding it with the key facing up. If you hold the lock in a different position during disassembly and do not insert the key, the insides will spill out and you will not understand how to put them back together. In this case, the ball with springs may get lost.
3. Remove the locking mechanism, which consists of two spring-loaded parts, and pull out the spring itself.
4. After removing the key, carefully remove the core so that the ball with the spring (located on the side of the cylinder) is not lost.

To disassemble the case, you need to unscrew 3 screws

Before replacing, it is necessary to remove the return spring from the old cylinder, since it is not sold complete with a new core. The spring is inside the part on the back side in a cocked state; it must be installed in the same form on the new cylinder. Also, do not forget to remove the thin spring from the hole where the ball is inserted.

The locking mechanism tongue peeks out from the bottom of the case

The larva must be pulled out so as not to lose the details

When installing the core, you need to move the spring for the ball into the hole and insert the part into the body. Then push the larva all the way, while simultaneously inserting the ball into the socket. After that, all that remains is to assemble the locking mechanism and tighten the housing with screws. When finished, check the operation of the ignition switch by turning the key to different positions.

The ejection spring from the old core needs to be moved to the new one

Do-it-yourself ignition switch illumination on a VAZ 2110

If you are tuning the interior of your car, then there is another interesting idea for you about creating LED illumination in your car. In our article you will learn how to illuminate the ignition switch on a VAZ 2110 car. The main thing in this matter is to maintain the color scheme of the entire interior. If you do everything in the same color as the rest of the luminous elements of the interior, the effect will be simply fabulous. Let's look at all the possible options for installing this device on a car. The standard lighting of the castle is an Ilyich light bulb shining into the lock cylinder itself

In appearance, the car's standard illumination does not attract attention in any way, one might even say that it frightens the eye. The cheapest and easiest way to replace the lock illumination is to simply replace the standard light bulb with an LED, but this procedure will not bring the desired result

In addition, when replacing lamps, you will need to invest a lot of effort to get the job done. There is another, more modern and beautiful option - to make the lighting in the form of a ring. If you want to illuminate the lock in the form of a ring, like on many foreign cars of our time, then use what is written here. For work we will need: 1. LED strip - one piece (any color of your choice) 2. 1 kOhm resistor - one piece 3. Super glue. 4. Soldering iron. 5. Tin. 6. Rosin. 7. Plexiglas (not thick).

So, let's get to work. To replace the backlight, we will need to disassemble the entire steering column trim and then remove the ignition switch. When the place for tuning is ready, we begin to prepare all the materials for work. First, we need to solder a resistor to the LED strip; if one is not available, then you can use single LEDs (available in multiple lighters). Then we solder pieces of wires of different colors to the poles of the LEDs so that next time we can change them without the help of a soldering iron. Then we make a ring from plexiglass. Next, drill a hole in the ignition switch housing. The hole in the lock is needed to insert the LED strip into it. In the example, you will see that an LED strip 15 centimeters long can easily be placed inside the lock without creating any problems.

The LED strip is held inside the lock due to the fact that the sides of the lock securely fix it. In order for the light emanating from the LEDs to be diffused, you need to either slightly process the back of the ring, or remove the chamfer that is installed on the ignition switch.

If you don't have plexiglass, you can make a ring using a regular jar lid, or use fiber optic wire. You can purchase fiber optics at any store that specializes in Internet connections. But still, in my opinion, plexiglass is the best option. Once the LEDs are in place, attach them to the power supply and then reassemble all the parts in reverse. Next, turn on the dimensions and enjoy. Everything is ready to use. For this work, nothing was given at all, 20 rubles, but what an effect.

Step-by-step instructions for changing the ignition switch

Before you start changing the ignition switch in a VAZ 2110 car, you need to fulfill the main condition, namely, turn off the power to the vehicle. It is necessary to disconnect the “-” terminal on the battery; only after such actions can you begin to remove the cover on the steering column. To facilitate the process of replacing the cylinder, it is recommended to dismantle the entire ignition switch. After replacing the element, the working lock is installed in its place. If we consider the financial side of the issue, it can be noted that changing the contact group will be much more profitable. As in the previous case, you cannot do without removing the casing and the lock itself. To avoid unpleasant moments, when disconnecting the contact group, it is advisable to mark all the dismantled wires. Such measures will prevent tangling and save valuable time.

Note! In rare cases, there may be a retaining ring in the contact group that can be removed with an awl. Upon completion of changing the contact group, you need to put the retaining ring in its original position.

Changing the ignition switch for a VAZ 2110

To change the ignition switch of the "tens" it is not necessary to have any superpowers. At the same time, ignorance of some of the nuances will make you suffer a little and tinker.

Like other repair work, it is recommended to change the ignition switch by following the instructions provided:

When replacing a part, you need to use special bolts with break-away heads. Most craftsmen advise replacing them with 20 mm M6 bolts. This can be explained by the fact that they are easier to remove when the next lock repair is necessary.

Note! Despite such advantages, there is a downside, namely a decrease in the safe level and anti-theft protection of the vehicle.

You will need a chisel to loosen the bolts.

They must be used with extreme caution. In the worst case, you can cut off the head of this bolt. Before changing the ignition switch in a VAZ 2110 car, you need to insert the key into it, turning it to the first position

These measures must be taken to enter the lock body of the latch-lock, which blocks the steering shaft mechanism.

• After these steps, switch
  can be placed on the steering column, but it must be secured with a bracket and tightened with new bolts for fastening.
• After removing the key from the lock hole, it is necessary to verify the functionality of the steering shaft locking mechanism. If for some reason the shaft lock does not work after turning the steering wheel, you need to adjust the location of the ignition switch on the steering column.

Note! The actions continue until the latch falls into the corresponding groove.

If, after adjustment, the locking mechanism still does not work, you need to use a size 10 spanner to tighten the bolts. The bolts are carefully tightened until their heads come off.

Of course, you can repair your car at a car service center, but if it comes to minor repairs, for example, changing the ignition switch in a VAZ 2110, you can do it yourself using videos and photos. This is a simple procedure that requires a minimum of knowledge, skills and time. If you replace the part repeatedly, the instructions will no longer be needed. Since the cost of repairs at a service station is considerable, independent actions make it possible to save significantly, the main thing is to purchase high-quality spare components.

Such work as replacing the ignition switch on a VAZ 2110 and 2112 is not uncommon. The reason for frequent malfunctions is the constant operation of this structural element. Low quality parts also have a negative impact. Before replacing, make sure that the problem is in the lock. Sometimes, similar symptoms can occur with other breakdowns. To work, you will need a minimum of tools, but in some cases, it may be difficult to remove the spare part from the car. Do everything carefully and carefully. Then you won't have any problems with this. Please note that the ignition switch has a mechanical anti-theft device.

Tools you will need for your work

To perform the work you may need the following tools:

• chisel;
• hammer
• socket wrench 10;
• a set of standard screwdrivers and wrenches;
• pliers or round nose pliers;
• sandpaper.

An experienced master will spend about an hour on the job, a beginner will have to tinker twice as long. But this is a completely justified time investment, since it allows you to save money - as of January 10, 2019, the average price for replacing the ignition switch of VAZ 2112, 2110 and 2111 in car services costs 800 rubles. In addition, the car owner will be charged another 500 rubles for adjusting the system. While the complete unit itself costs about 1 thousand rubles. Replacing a contact group will cost the car owner about the same money, when the element itself costs an average of 300 rubles.

How to remove and install the part?

If the ZZ is not working, then it needs either repair or replacement. The ignition switch on a VAZ 2110 is replaced only if the device cannot be restored or repaired. In all other cases, you can and should try to repair it.

So, for repairs, do not forget to disconnect the battery and follow these steps:

1. First of all, you need to unscrew the screws that secure the mechanism. First, the on-board network is de-energized; to do this, remove the “-” terminal from the battery. After the plastic cover is removed, the steering column switches are disabled. In this process, removing the bolts is one of the most difficult steps. This is because VAZ engineers initially thought through this point so that in the event of a vehicle break-in, an attacker would not be able to quickly unscrew the unit. Therefore, even at production, the edges of the screws are cut off, so you will have to use a chisel to dismantle the screw. Using a chisel, you only need to move the heads a little from their place, after which the bolts can be unscrewed without any problems using pliers.
2. When the protection is removed, it is necessary to understand what the essence of the problem is. If you need to replace the backlight bulb, you should first disconnect the connector. Using small pliers, remove the lamp socket itself. Just replace it with a new one and install it back.
3. If the problem lies in the operation of the contact group, then you need to either repair it or replace it. As practice shows, repairs often give the necessary results. However, the cost of new elements for a contact group is often not much lower than the price of the group itself. So, to prevent possible problems in the future, it is advisable to completely change the group. To replace using a screwdriver, you simply need to press the latches and remove the component. In the same way, only in reverse order, a new one is installed in accordance with the ignition switch diagram.
4. If you need to change the key controller switch, use a Phillips head screwdriver to remove three bolts. Then the rod is removed from the structure, and then the latch is released and the switch itself is dismantled. Finally, you just need to install a new element in place of the old one.
5. As for installation, in general there is nothing complicated about it - all steps must be repeated, only in reverse order. But during the installation there is one point that should be taken into account. Before starting reassembly, set the key in the lock to the first position. In this position, locking the steering wheel will be impossible. Therefore, the latch, located on the shaft itself and performing the function of a lock, should easily fit into the corresponding connector on the 3Z itself. Only after these steps can the device be installed. In addition, for installation you will need new 3Z fixing fixtures, since it will be impossible to install the old ones. When installation is complete, you need to make sure that the steering wheel will lock when the key is removed. If this does not happen, then you will also have to adjust the position of the ZZ on the column.

The request returned an empty result.

Dismantling

If previous activities have shown that intervention in the design of the ignition switch is required, work in any case will begin with dismantling the device.

We have special step-by-step instructions for this.

1. To begin, disconnect the negative terminal from the battery of your VAZ 2110. This way you will ensure your safety and the safety of all wiring. You know what the consequences of a short circuit are.
2. Next, remove the casing on the steering column. This is how you gain access to the castle.
3. If you feel that the rotary switches will interfere with your work, it is better to remove them immediately. The work does not last for a couple of minutes, so all irritants should be put aside.
4. Armed with a chisel and hammer, unscrew the mounting bolts with round heads. Don't get confused, they are the only ones there. Try to perform this operation as carefully as possible so as not to knock off the bolt head.
5. Now take the pliers and remove the bolts.
6. Insert the key into the ignition and turn it to position zero. This will disable the anti-theft system.
7. Next in line is the bracket that held the previously removed bolts and the ignition switch itself.
8. Mark the contact wires using different colored markers. Otherwise, you can easily mix them up during reassembly.
9. Often it is not necessary to completely replace the lock, but only partial repairs. For example, change the backlight bulb, or fix a microswitch problem.
10. Disconnect the connectors that used to operate the ignition switch.
11. To replace the backlight bulb, disconnect the corresponding connectors, and then use pliers to remove the bulb.
12. To replace the contacts, use a screwdriver to press out the special latches.
13. Using a shaped screwdriver, unscrew three screws, after which you can remove the rod.
14. Use a regular flathead screwdriver to pry out the clips and remove the microswitch.
15. Next, new ones are inserted in place of the dismantled elements.

Checking status

Do we replace the entire lock, or just the contact group?

The issue is purely economic in nature. It is clear that replacing the complete lock will cost three times more, so before replacing the ignition switch completely, it is worth understanding the causes of the malfunction. It is possible that it will be enough to simply replace the contact group if everything is in order with the cylinder and the mechanical part of the lock.

Appearance of the contact group

Ideally, it is better to replace oxidized, and even more so burnt, contacts, however, they can simply be cleaned with very fine sandpaper. Diagnostics of the contact group is carried out using a multimeter in ohmmeter mode. Each pair of contacts on the terminal block is checked using the probes of a multimeter - we turn the key in the ignition switch and test each pair of contacts on the terminal block for a short circuit; if the multimeter shows zero resistance, everything is in order with the contacts.

We check each pair of contacts on the terminal block

There may be problems with the mechanical part of the lock, and in this case, experts do not recommend changing the cylinder yourself - firstly, it is quite difficult to find it on sale, and secondly, replacing the cylinder may be carried out incorrectly and, as a result, the entire lock will not work incorrect. In this case, it is more rational to buy a complete lock and replace it completely. It's more reliable and safer. Good luck to everyone and good travels!

How the larva changes - video

The video demonstrates how to disassemble the mechanical part of the ignition switch of a VAZ 2170 (Lada Priora), but in design it does not differ from the elements installed on VAZ 2110-2112 cars.

As a rule, there is no need to change the entire ignition switch, although car enthusiasts often resort to this option to save time. The operation will take the technician at the service station no more than 20 minutes. Replacing it yourself will require more time, but you will be able to replace only the broken part (cylinder or contact group), thereby saving personal funds.

Reasons for replacement

It is necessary to replace the entire lock or just the contact group, depending on the nature of the breakdown and the situation with your car. Therefore, we will consider options when replacement may still be required.

When checking the contact group, be sure to disconnect the negative terminal from the battery, otherwise a short circuit will occur, and not only the contactor will have to be replaced.

Circuit and pinout

First of all, get acquainted with the lock diagram and wire connection diagram, which will allow you to better understand the features of the 3Z pinout.

As you can see, the pinout includes 8 elements. What does each of them mean and what functions are they responsible for? We'll figure out.

1. Power supply for the inserted key sensor microswitch (+12Volt).
2. Power supply to ground when doors are opened on the driver's side.
3. Power supply that supplies current to the starter (+12Volt, pin 50 on the diagram).
4. Source at +12Volt. Activated after turning on the ignition. Power supply for additional equipment, such as video recorders, clocks, etc. (pin 15 in the diagram).
5. Source at +12 Volts. Triggers when the key is inserted. Goes to pin 5.
6. Power supply +12Volt. The illumination of the 3Z larva is activated.
7. +12V source from the battery (pin 30 in the diagram).
8. Not active.

Wiring

Replacing the contact group of the ignition switch of a VAZ 2110

But all electrical faults should be looked for in the contact group. Moreover, it is not at all necessary to change the entire lock completely. There can be many problems, since almost all consumers are connected to the contact group of the lock, and if you do not use the diagram provided, you can easily get confused. To check the functionality of the contact group, you will have to ring each contact using a multimeter. Loaded contacts can sometimes burn out; in this case, it will be enough to simply clean them with a diamond file. You can check the contact group in a simpler way by removing the ground from the battery and dismantling the lower steering column casing. If you disconnect the connector from the ignition switch and check each contact with an ohmmeter, then a serviceable contact group will not short out any of them.

The result of the work done

From all of the above, we can conclude that all these operations are quite simple and, with a minimum amount of tools, anyone who knows how to use a screwdriver and wrenches can do this. And if you do everything yourself, you can save time and money on a trip to the service center.

Our VAZ-2112 is unlikely to have any value if it is impossible to move it. Moreover, for such a banal reason as a malfunction of the ignition switch. An essentially trivial breakdown can lead to loss of time, and sometimes even to the loss of the car itself if the ignition switch is faulty.

Replacing the ignition switch on a VAZ-2110, 2111, 2112

• If the key is lost or the lock fails, the engine cannot be started.
• In addition, the lock also blocks the steering column, and if your car breaks down far from a service center or a car store, and you have no one to ask for help, the car can only be taken away by a tow truck.
• But if you have the opportunity to buy a lock and have a minimum number of tools, you can replace it yourself.

Malfunctions of the ignition switch VAZ 2110

Malfunctions of the ignition switch of the VAZ 2110 and its family are as follows:

• Mechanical destruction - failure of the lock cylinder, steering column locking mechanism, deformation of the key, jamming of the lock in the on position (the engine is running, the car does not stall when you turn the key);
• Electrical circuit failure is excessive wear of the lock contacts and, as a consequence, failure of its electrical part.

Replacing the ignition switch on a VAZ 2110 car

All cars of the VAZ 2110 family have the same ignition switch. It changes in the same way. To remove and install it you will need the following tool:

• crosshead screwdriver;
• pliers;
• thin, sharp chisel;
• hammer;
• key to 10.

The procedure for removing the lock is as follows:

Remove the plastic steering column casings by first unscrewing their fastening screws (they are located below, on the side of the lower casing);

Remove the left steering column switch (turn indicators);

Disconnect the ignition switch connector;

Using a chisel and hammer, unscrew the bolts holding the lock on the steering column; to do this, it is necessary to place the sharp edge of the chisel on the head of the bolt at such an angle that when it is hit with a hammer, it turns the bolt counterclockwise;

After breaking the tightening, completely unscrew the bolts with your fingers or pliers.

So, you have the old lock in your hands, you can install a new one.

Installation is carried out in the reverse order, but with one feature: the new bolts are supplied complete with a lock with tear-off caps, this is a kind of alternative to a torque wrench.

The manufacturer recommends tightening the new bolt until its head comes off. This tightening is considered quite strong.

Replacing door and trunk cylinders

To replace the door cylinder, you must remove the interior door panel. It is held on by two screws and pistons located around its perimeter.

Procedure for removing the casing:

Unscrew the “soldier” of the lock from the interior.

Remove the decorative trim of the door open/close handle block from the inside.

Unscrew the screws hidden under it. After releasing the handle, remove it from the rod.

1. Unscrew the screws of the decorative speaker trim and remove it.
2. Use a flat-head screwdriver to pry the lock of the window lifter handle and remove it.
3. Use a special plastic mounting spatula, or something similar, to carefully remove the panel pistons from the door.

It is recommended to pre-purchase several pistons, because... they often break.

Replacing lock cylinders

• Once the panel is removed, you can begin replacing the door lock cylinder.
• It is necessary to disconnect the rod going from the cylinder to the lock by prying it with a screwdriver from the drive side of the cylinder.
• Next, use pliers or a screwdriver to pry the cylinder lock and remove it from the door, then insert a new cylinder and assemble everything in the reverse order.
• All that remains is to pull out the larva.
• Replacing the trunk lock cylinder is somewhat simpler.
• To do this, remove the trunk lid trim, after which full access to the entire lock mechanism opens.
• We unscrew the bolt securing the button with the cylinder to the trunk lid, and remove the mechanism assembly, disconnecting it from the rod going to the lock itself, and replace it with a new one.
• We install and assemble the trunk lid in the reverse order.

The result of the work done

From all of the above, we can conclude that all these operations are quite simple and, with a minimum amount of tools, anyone who knows how to use a screwdriver and wrenches can do this. And if you do everything yourself, you can save time and money on a trip to the service center.

Instructions for removing the element

For disassembly you need to prepare a simple set of tools:

• 10 mm head and ratchet drive;
• Phillips screwdriver;
• narrow chisel (width 5-8 mm);
• hammer;
• round nose pliers with tapered, curved ends.

Ignition switch replacement tool

To successfully install a new or repaired lock in place, it is advisable to purchase 4 special fastening bolts with M6 threads with a head size of 10 mm and a length of 20 mm. Their feature is the heads that come off with a key at a certain tightening torque. After tearing off the heads, semicircular caps remain on the surface, which are much more difficult to unscrew for an untrained person. But you will have to do this during disassembly.

The battery must be disconnected before starting work.

Like any event related to tampering with the electrical part of the car, dismantling the ignition switch begins with disconnecting the negative terminal of the battery. Then proceed in this order:

1. Using a Phillips screwdriver, remove the screws holding the two halves of the plastic frame of the steering column together.
2. Lower the handle that fixes the position of the steering wheel during adjustment all the way down and remove the plastic panels. Disconnect the ignition switch block and carefully cut the tape connecting your bundle of wires to the common harness. In order not to cling to the steering column switch during operation, it can also be pulled out of the connector.
3. On the metal casing of the steering column you will see a lock mount consisting of two clamps. They are held together by 4 bolts with the heads torn off (visible on the left side). Pointing the chisel at the semicircular caps, use a hammer to loosen the tightening of these bolts one by one.
4. Using pliers and then your hands, unscrew all 4 bolts and remove the ignition switch.

Unscrewing the plastic steering column cover

Bolts with intact heads can be unscrewed with a wrench

At the stage of disconnecting the connectors, it becomes possible to check the functionality of the contact group by measuring resistance, as described in the previous section. If you remove the lock due to the loss of the keys and want to move on, then after dismantling you need to do the following:

1. On the “mother” block, which remains hanging after the lock is turned off, find contacts with thick wires of purple and blue color (the latter with a black stripe).
2. Connect these terminals with any conductor, after which the ignition will turn on.
3. The thick red wire leads to the starter. To start, its contact must be temporarily connected to the installed jumper. When the engine starts, the red wire must be disconnected.

This is how jumpers are inserted into the block to start the engine without a key.

After unscrewing the fasteners and disconnecting the wires, the lock can be easily removed from the car

Assembly is carried out in the reverse order, but taking into account the following precautions:

• do not tighten the fastening bolts until you have accurately aligned the position of the lock on the casing so that the facing plastic panel fits smoothly into place;
• before final tightening the bolts, make sure that the lock snaps into place when turning the steering wheel, otherwise adjust the position of the lock;
• The tightening torque should be such that the heads of the new bolts come off and the round heads remain.

When installing and tightening the bolts, their heads should come off

If you think that special fasteners are not an obstacle for car thieves, then you can screw in regular bolts with M6 threads and carefully tighten them.

Starter malfunctions and reasons for their occurrence

The unit does not spin the flywheel due to many factors. Below we will discuss defects in the immobilizer, pull-out relay, injector, as well as in the car wiring. Sometimes repairs are not enough, in which case the device needs to be replaced.

Faulty injector

The standard version of the VAZ 2110 is not equipped with injectors, but they can be supplied separately. Drivers choose these devices for many reasons: reduced fuel consumption, no need to warm up the engine in cold weather, increased power characteristics.

The arrow points to the starter relay

If the starter is not working well, then you need to check the injector, which may be acting up due to bad gasoline. This is the only drawback of the injector - it requires high-quality fuel. It is also worth checking whether the connection diagram is followed.

Overrunning clutch failure

If the overrunning clutch breaks, the engine starts and runs perfectly. But when the car stops, the engine cannot be restarted; it clicks but does not start. In this case, you need to wait until the power plant has cooled down, and only then try to start it.

Also in this case, it is worth inspecting the wiring that comes from the coupling. Sometimes replacing damaged wires can solve a problem where the engine clicks but won't start. Another sign of a faulty clutch is the radio turning on spontaneously.

Solenoid relay

Once behind the wheel, the driver inserts the key and turns it, the fuel pump starts working, the dashboard lights up, but when turning further, the pump and the panel turn off, and the starter does not turn. In such a situation, the solenoid relay is most likely to blame.

Removing the solenoid relay

First of all, you need to check whether there is voltage going to it. If it does, then it’s worth checking the lock itself or the alarm system, which may close the circuit. If all the elements work separately and do not start together, then the starter does not turn due to the solenoid relay.

Poor contact

In this case, the starter starts after several attempts, but it still clicks. This problem occurs due to damaged contacts. The inspection should begin with the battery. If the terminals are oxidized, you need to clean them.

If this does not help, then you should check the starter contacts, because when they are oxidized, the device turns poorly or does not start the crankshaft at all. If the starter refuses to work, but the immobilizer is running, then there is a malfunction in it. Here you won’t be able to remove the defect yourself - you need to go to a car service center. Now readers know how much it costs and why the starter does not work; it is worth doing the work yourself only if you have experience working with wiring.

The connecting link of the whole organism

There is a misconception among most car owners that the main thing in a car is the engine, transmission, and chassis. Someone will ask, why is it wrong? It is necessary to consider the machine as a single, whole organism. And all components and assemblies are exclusively components.

For example, a breakdown of the starting system will lead to the fact that the vehicle will stop and will not be able to continue moving. Requires prompt repair. How well the example was chosen is the topic of today’s article. However, whether or not the reader agrees with my statement is up to him to decide individually.

Board layout and layout

For the entire Lada line, the lock is located on the right side of the steering wheel, sewn into a plastic box, presented in the form of a complete block made of duralumin alloy. On the back side there is a board with contact connectors (8 in total). The contact group of wires has strictly its purpose, the diagram (pinout) is as follows:

1. Key microswitch;
2. Voltage directly from the battery;
3. Reserve socket for connecting other devices at the driver’s discretion.

Despite the fact that old and new locks are sold, with and without backlighting, the structure of the core and contact board is absolutely identical. When the wire connection diagram does not match, carefully refer to the operating instructions.

Symptoms of a problem

1. After starting the engine, the car key does not return to position “II”. This indicates that the ignition switch cylinder is already very worn, the return spring is weak, and the resistance has decreased. At this moment, the starter and motor work simultaneously, which is detrimental to both components of the car. Systematic such “starts” will lead to the fact that the owner will have to buy new “brushes” for the starter, worse when the starter is entirely. And this is not a cheap pleasure. The spring cannot be repaired, so purchasing a new one is required.
2. Mechanical damage due to an attempt to steal a vehicle by intruders;
3. The entire system does not work: due to careless handling by the driver himself. It's no secret that each of us has our own manners and driving style. Some treat their “favorites” with care, others change them like gloves.

Solutions

Drivers without experience, as practice shows, at the first breakdown, run to service stations or car markets to buy a new ignition switch, giving away their hard-earned money. My advice is, don't rush to do this. Perhaps the reason is completely trivial, not worth such waste. Do-it-yourself replacement will take no more than 5 minutes. If you are not sure, contact a highly qualified electrician at a service station to carry out diagnostics and identify the fault. Having the skills, disassemble the lock and repair the damage. The lock from Priora is similar in design to the younger and older models, for example, the VAZ 2107, and the VAZ 2114 has a similar structure.

How to replace and disassemble?

For those who are unsure, you can use the car's operating manual, which describes in detail this or that unit, connection diagram, assembly, and photos are attached. Agree that the difference in price is significant, whether to buy the entire lock, or just the core.

Recommendation: good quality spare parts and components from the Dimitrovgrad Automotive Assembly Plant (DAAZ). Buy it, you won't regret it. The online store will help you quickly buy a part directly from the manufacturer. To choose a particular brand, be sure to read customer reviews and watch video tutorials.

The main thing when starting the car is to use the original key that “comes” from the factory. Since the immobilizer is a kind of anti-theft device that will prevent the engine from starting. The electrical circuit is connected to the car alarm or central locking.

If your car key is lost or fails for any reason, you must contact certified service centers to make a duplicate. Some “craftsmen” manage to deactivate the immobilizer, but this is similar to disabling the antivirus program on the computer. Would you do it? I doubt. One can only guess how much the repair costs.

This concludes the discussion of the topic. I really hope that the article will be useful to many readers. Due to numerous requests from car enthusiasts, in the following articles we will consider such topics as the injector, the on-board computer displays errors on the VAZ 2114, the clutch cable on the VAZ 2114 has fallen, what to do

Thank you all for your attention. See you soon

The engine won't start?

If, as a result of the check, it became clear that the spark hits the spark plugs, but the VAZ 2110 injector engine still does not start, then it is also necessary to diagnose it. The faults that cause this problem can be serious or not very serious.

At the same time, it is sometimes possible to cope with their solution without anyone’s help:

• It is necessary to purchase a spark gap and a Hall Sensor, which is inexpensive, but has an irreplaceable purpose. With their help, you can find out about the presence of a spark in the candles;
• Check the spark plugs to see if they are OK. A spark gap can be used for this purpose. However, you need to remember that the controller will be broken if candles are placed on its body;
• Perform fuel pump diagnostics. When you try to start a VAZ 2110 car, a characteristic sound will appear from under the rear seat. If there is no sound, then you need to check the fuses and the main relay. In a VAZ 2110 car they are located behind the side cover of the driver's seat.

If, after diagnostics, problems were identified with one of these elements, then you can fix them yourself. Usually the spark plugs begin to work after proper wiping, although this does not always happen, so they have to be replaced.
