Replacing the ignition switch on a VAZ 2110: wiring diagram

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

The ignition switch of a car is almost the most important part.
This part is subject to increased wear, because It is used every time you start and stop the engine, and on domestic cars, alas, its quality is not the best. 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.

Unscrew the screws of the decorative speaker trim and remove it.

Use a flat-head screwdriver to pry the lock of the window lifter handle and remove it.

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.

The work is carried out as follows:

1. When making a replacement, use special bolts with break-away heads, which some motorists recommend replacing with twenty-millimeter M6 bolts, citing the fact that these are easier to remove if the ignition switch needs to be repaired again. Of course, this is so, but there is another side to the coin: by making it easier to disassemble the ignition switch, you yourself reduce the level of security and anti-theft protection of your car.

2. In order to loosen the bolts, you will need a chisel; when using it, you should be extremely careful so as not to accidentally cut off the bolt head;

3. Before replacing the ignition switch of the VAZ 2110, insert the key into it and turn it to position “I”, this is necessary so that the latch locking the steering shaft mechanism enters the lock body.

4. After this, you can install the ignition switch on the steering column, and secure it with a bracket and tighten it with new mounting bolts.

5. After removing the key from the keyhole, be sure to make sure that the steering shaft locking mechanism is working. If the shaft lock does not work after a full turn of the steering wheel, you will need to adjust the position of the ignition switch on the steering column until the lock latch fits into the groove on the steering shaft.

6. Once the adjustment is complete and the locking mechanism is working, using a “10” spanner, carefully tighten the bolts until their heads come off.

That's all I have, now we can say with confidence that the work is finished!

Ignition switch VAZ 2110 diagram, repair, replacement of ignition switch VAZ-2110 video

The VAZ 2110 ignition switch is essentially an electrical breaker that makes and breaks the contacts of electrical circuits. The main purpose of the ignition switch is to start the engine. In addition, the ignition lock protects the VAZ 2110 from theft, especially effectively if the car has an immobilizer that will not allow you to start the engine without the original key with a code.

The VAZ 2110 ignition switch, the diagram of which is shown in the image below, is quite traditional for modern cars. Let's look at the schematic drawing.

A special plug with 8 contacts fits the ignition switch, on the right in the lock diagram. Each contact is used for its own purpose. For what purpose, look further.

• 1 – comes (12 W) for the micro switch of the inserted key
• 2 – ground arrives (zero) when the driver’s door is opened
• 3 – goes (12 W) to the starter (50 in the diagram)
• 4 - goes out (12 W) after connecting the ignition (in diagram 15)
• 5 – goes out (12 W) with the key inserted into the lock at 5 to the BSK contact
• 6 – comes (12 W) to illuminate the lock cylinder
• 7 – comes (12 W) from the battery (30 in the diagram)
• 8 – not used (reserve for connecting additional consumers)

The position of the key according to the diagram determines the operation of the ignition 2110 as follows. In position “0” the ignition is turned off (contacts 30 are energized). In position “I” the ignition is on, when you turn the key to this position you can turn on the headlights, side lights, turn signals, windshield wipers and washers, the instrument panel, cigarette lighter, electric interior heater fan, rear window heating starts working (contacts 30-15 are energized ). Turning the key to position “II” is the normal position of the key in the ignition switch when the engine is running. But in order for the starter to work and the engine to start, the key must be moved slightly until it comes into contact with pin 50. Then the current goes to the starter, it in turn starts the engine, then the key should be released and in a working ignition switch it will return to position “II”, the starter will turn off and the engine will continue to run. Perhaps the most common breakdown of the ignition switch is when the key does not automatically return to position “II”, the starter continues to work simultaneously with the engine and fails.

Next, we offer a video on this topic, repairing the ignition switch on a “ten”. For clarity, we offer a video of replacing the ignition switch of a VAZ-2110 .

To remove the ignition switch of a VAZ-2110 , you must unscrew the negative terminal from the battery. This is a guarantee that you will not damage the electrical circuits of your car. Then unscrew the plastic covers of the steering column from below and disconnect the steering column switches. Perhaps the most difficult thing is to remove the ignition switch itself. After all, when installing it, the edges of the fastening bolts are cut off, this is done to make life more difficult for car thieves. An ordinary chisel will come to the rescue. Let's look at the photo (for clarity, the steering wheel has been removed from the photo) -

Replacing the ignition switch for VAZ 2110, 2111, 2112

One of the most common reasons for the inability to start a VAZ 2110, 2111 or 2112 may be a failure of the ignition switch. This node switches or disconnects groups of electrical circuit contacts, activating or switching off the engine. If there is a problem with it, the driver simply will not be able to operate the car. Replacing the ignition switch of VAZ 2110, 2111 and 2112 is a simple operation; it is quite possible to do the repair yourself. But before you repair the unit, it is advisable to familiarize yourself with its diagram. It is similar on all of the above VAZ models.

Required spare parts

Depending on the type of repair, you may need:

1. switch with assembly (articles: 2110-3704005, 2111-3704005, 2112-3704005, VLT21104-6105006, VLT21104-3704005);
2. contract group (items: 2110-3704005, 2111-3704005, 2112-3704005);
3. bolts with heads that can be torn off, or M6 bolts.

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.

Order of Operations

It is worth immediately noting that independently replacing the ignition switch cylinder of VAZ 2110, 2111 and 2112 is problematic. This part is difficult to find on sale, and working with it requires special skills. An incorrectly performed operation will result in unstable operation of the ignition system. In this case, you need to purchase the assembly and change it completely:

1. Since there is work to be done on the on-board electrical system, you need to disconnect the battery; to do this, disconnect the negative terminal of the battery. In addition, it is rational to provide good lighting in the work area, so you will spend less time performing operations.
2. Now you need to lower the steering column all the way and remove the plastic casing, after unscrewing the screws.

Using a chisel, unscrew the bolts with cut heads and pull them out with pliers. Hammer blows should be directed clockwise.

Now you can remove the bracket and the lock itself from the steering column by disconnecting the electrical connector.

If the backlight lamp needs to be replaced, the contact is disconnected and its socket is removed with pliers. Installing a new device.

To replace the contact group of the ignition switch of a VAZ 2110, 2111 or 2112, the clamps are released.

If the microswitch stops working, unscrew the screws, remove the rod, and pull out the latch. We install a working device.

• We replace the contact group of the ignition switch of VAZ 2110, 2111 or 2112.
• Now the operations are performed in reverse order. We install the assembled unit on the steering shaft, clamp it with a strap and tighten it with bolts. They need to be screwed in all the way; for this you can use a 10mm spanner or a socket with a knob. IMG8
• Without breaking off the heads from the fasteners, we begin to adjust the steering wheel: the key is located opposite the I icon, and the steering shaft is in the same position. If the shaft does not lock and the steering wheel continues to rotate freely, you need to find the correct location of the lock so that its latch engages the groove in the shaft.
• Now you can break off the heads from the bolts.
• Once again we test the functionality of the mechanism. If everything is in order, you can connect the contacts.
• We connect the lock with the battery by replacing the negative terminal. And again we test the performance of the node. If the results are positive, the decorative plastic casing is mounted in its original place.

Failure of the lock may be due to normal oxidation of the contacts in the group. In this case, you only need to clean with fine sandpaper. This malfunction can be determined using a multimeter in ohmmeter mode. Each pair must be tested for short circuits.

Let's summarize

Repairing the ignition switch of a VAZ 2112, 2110 or 2111 is a simple procedure, as is replacing the group of contacts of the unit. You can do it yourself, saving money. To replace the entire switch, experts recommend purchasing a Togliatti lock with article number 21100-3704005-30. He is considered the most reliable.

Installation of a new larva

Ignition switch daewoo nexia and matiz: replacing the assembly, contact group and cylinder
To change the lock core due to mechanical failure, remove it from the car 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

Replacing the ignition switch

If on old domestic cars the ignition switch could be changed without much difficulty, then on Priora and other front-wheel drive cars you can take longer with this repair. Basically, the reasons why replacement is necessary are as follows:

To replace the ignition switch, you will need the following tool:

1. Sharp and thin chisel
2. Hammer
3. 10 mm wrench
4. Phillips screwdriver
5. Long nose pliers

Report on replacing the ignition switch on a Lada Priora

So, to get to the lock mount, we first need to remove the steering column cover. After this, this entire structure becomes available to us. Now, using a sharp chisel, you need to tear off all the bolts securing the lock, since the caps there are without edges.

Actually replacement...

The first thing that is necessary before changing the ignition switch of a VAZ 2110 is to turn off the power to the car. To do this, disconnect the negative terminal on the battery, then remove the steering column cover. In order to facilitate the procedure for replacing the cylinder, it is necessary to remove the ignition switch, then replace the faulty cylinder with a working one and put the lock back.

If we talk from a financial point of view, we can say that replacing the contact group is the most profitable. The disassembly principle is somewhat similar to the previous one; you will also have to remove the casing and lock. In order to avoid any unpleasant moments, I advise you to mark all the wires being removed when disconnecting the contact group; this will allow you to avoid confusion and save your time. Some cars have a retaining ring in the contact group, which you will need an awl to remove. After replacing the contact group, do not forget to return the retaining ring to its place.

To replace the ignition switch of a VAZ 2110 you also won’t need any super abilities, but if you don’t know some of the nuances, you can tinker a lot and get tired.

How to change the ignition switch on a VAZ 2110 with your own hands

Professional advice

Such advice is as follows:

1. Even having an understanding of the rules for replacing larvae and contact groups, it is better to refrain from this work. The repair process is complex and time-consuming. If you have an idea of ​​how to change the ignition switch on a VAZ 2110, then it is better to replace the entire assembly.
2. Graphite grease is used as a lubricant for the cylinder. It reduces the risk of biting the part.
3. Even knowing how to change the ignition switch on a VAZ 2110, as well as how to change the door lock on a VAZ 2110, in the process of work you should give preference to branded products.

The procedure for replacing the ignition switch on a VAZ 2110 is a simple type of repair work. Even a beginner will not experience big problems. The main thing is to have the necessary equipment and tools on hand, and also to read the instructions well.

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.
