Lada Priora (2013+). Car pulls or skids when braking
Reasons for the car to pull or skid when braking
| Cause of malfunction | Elimination methods |
|---|---|
| Wheel cylinder piston jamming | Replace cylinder |
| Blocked brake lines: tubes or hoses | Replace damaged tubes and hoses |
| Separation of the lining from the base of the brake pad | Replace the block (it’s better to have everything on the same axis at the same time) |
| Oiling of brake discs, drums, linings | Clean oily discs and drums and replace pads. Eliminate the cause of the oiling |
| An ice or salt crust has formed on the surface of the linings (in winter). The pads are wet | When starting to drive, check the brakes at low speed. In the rain and after driving through deep puddles, dry the brakes by lightly pressing the brake pedal. |
| Different tire pressures on left and right wheels | Set normal pressure |
| Significant difference in tire wear | Replace your worn tire |
| The pressure regulator drive is incorrectly adjusted | Adjust the drive |
| Pressure regulator faulty | Replace regulator |
| One of the circuits of the service brake system does not work (braking efficiency is significantly reduced) | Eliminate fluid leakage from the brake system, bleed the system |
| Brake disc deformation | Replace both drives |
| Wheel axial play (severe wear of the front wheel bearings or loosening of the hub nut) | Tighten the wheel hub nut, replace the bearing if necessary |
| Brake drum ovality | Grind or replace the drum |
| The strut shock absorber is faulty | Replace both shock absorbers |
| Uneven spring settlement of the front suspension | Replace both springs |
| Wheel alignment angles are incorrect | Adjust wheel alignment |
The main reasons for a car skidding
Changing wheel alignment angles over time
When operating a car, it is impossible to maintain the correct wheel alignment angles for a very long period of time, since if the wheels hit potholes and hit bumps while driving at any speed, the car's wheel alignment will change, even if its suspension is not damaged.
It's extremely important to check your wheel alignment every time you change your tires, but if your car requires alignment every two months or so, it's likely your suspension components are wearing out or you need to rethink your driving style.
Tire defects and uneven wear
If you don't adjust your wheel angles after installing new tires, they will wear out at an even faster rate than your old worn tires.
Effect of brakes on wheel alignment
Brakes do not directly affect wheel alignment, but they can change the direction the car is moving. If one of the brake calipers fails, the wheel controlled by that caliper can either turn freely when braking, or continue to brake after the brake pedal is released. As a result, during braking, the car pulls to one side, and after releasing the brake pedal, the direction of its movement changes.
Accident or suspension wear
If, after your vehicle has been involved in an accident, it begins to constantly pull to one side, or if problems with the suspension are identified that eventually lead to a change in the original position of the steering wheel, this is a high probability indicator of the need to replace the suspension components in the near future. This will help ensure the vehicle moves straight.
Exceeding the vehicle's carrying capacity
Overloading one or more vehicle components can cause wheel misalignment similar to what happens when a coil spring, leaf spring or suspension strut fails.
The ignition switch on a Lada Priora car starts the engine. In order for it to start, the machine needs to be given a command. The price of a part for a Priora car is from 1,800 rubles. Replacing the ignition switch is a simple procedure that a beginner can handle.
The driver, turning the key in the lock with the immobilizer in several different positions, gives the command to turn on the ignition or start the engine. Only after this everything starts to work: the starter turns, the crankshaft begins to move, and finally the spark plugs give a spark for the first portion of the air-fuel mixture. But the operation of all these parts may not take place due to a malfunction of the ignition switch on the Priora.
If the car does not start, and you are sure that the components are working properly and the battery is charged, you will have to remove it in any case to inspect and identify the fault. Repairs can be done by anyone; it’s enough to understand all the steps in detail. If it does not help, then the ignition switch needs to be replaced.
How to change and remove it on a Lada Priora car and how many actions need to be performed, you will learn from the article.
Once the ignition switch is turned, the car remains in the ignition even when you remove the key. Unfortunately, Priora is not deprived of this; as the lock wears out, this happens.
How long it will work depends on how you use it. If you use force once, you can break the ignition switch.
Standard ignition switch - article number, price, how it works, device
The module on Priora does not work directly with the components that initiate the engine start. So that it works properlyyou need to wait a few seconds before starting until the required pressure is created. On the Priora, only wires are connected to it - the paths along which messages pass from the ignition switch to the electronic control unit.
The ECU of the Priora car just receives data about the position of the key and can crank the starter if this operation is “not blocked”.
Due to a breakdown, it can only turn on the ignition, leaving the battery to work.
After the ECU key has turned, it gives commands to several parts at once. When you turn on the second position, let the fuel pump run for 5 seconds so that it pumps fuel from the tank closer to the engine.
When the starting process itself begins, the starter rotates - the force it creates goes to the crankshaft;
the ignition system element converts the low voltage current coming from the battery into a high one so that the spark plugs are “charged” and give a spark at the right moment;
The injector creates the first batch of air-fuel mixture to put it into the chamber, where everything is ready for it - the pistons “move”, the spark plugs spark.
In the module itself, everything is simple - there is a cylinder with a return spring inside, between the coils there is a locking ball that does not allow it to curl up more than necessary, and a locking rod holds the structure in place. Finally, as a complication of the entire system, there is an “immobilizer” - an anti-theft system that you can install yourself. It just takes a long time to set it up.
A regular kit with a master key and several door cylinders (with an immobilizer) costs from 1,800 - 2,000 rubles, catalog number - 2170-3704005.
A set without a master key (without an immobilizer) can be purchased for 1,200 – 1,400 rubles, article number -2170-3704006.
Diagram and pinout of the ignition switch on Priora
The diagram looks like this:
Using the diagram, you can track the presence of an immobilizer, as well as a blocker for excessive cranking of the starter. It starts from the battery - the pinout transmits voltage from it to point 30. Here the connection to K4 is a fuse relay. The contact group of the ignition switch of a Priora car will only work if the locking rod is in place and holds the key.
There are two positions in the diagram – I (ignition) and II (engine start). Replace the ignition switch of the Lada Priora in accordance with this diagram.
Basic faults
Usually the module is “sinned” when the battery is dead - nothing will turn on, even the ECU will not receive a signal. You can solve everything by charging the battery or installing a new one. But if you are sure that the key in the ignition switch has turned, but there is no “effect”, then the problem is in the module.
- Firstly, one of the dangerous problems is a faulty locking rod. As was said, it does not allow you to remove the key when it is in position I or II. If you accidentally notice that the key falls out, try to replace the block as soon as possible. It happens that replacement is taken due to an immobilizer error. This can only be done as a last resort, having accurately checked all possible “escape routes”, because reconfiguring the ECU will take a lot of time.
- Secondly, the wiring connected to the unit may become damaged, and it will become “cut off” from the Priora’s electronic control unit. It is necessary to ring all sections of the wiring and change it. In the same group of problems is the fuse relay. If the fuse is blown, the engine will not start.
- Thirdly, the spring may become deformed or break. This manifests itself in the fact that after cranking the starter and starting the engine, the key does not return to position I.
Removing and installing (replacing) the ignition switch on a Priora
Before removing and replacing the module, have a few tools ready:
- chisel;
- hammer;
- pliers;
- key "10";
- Phillips screwdriver.
Replacing the Priora ignition switch is carried out according to the following algorithm:
- Put the car on the handbrake, remove the negative from the battery.
- Remove the steering column covers - to do this, insert a screwdriver into the small technical holes and unscrew the bolts.
- In front of you will be a steering shaft, to which the ignition module is attached with four bolts. They are twisted very tightly - so that potential hijackers would have to waste time removing the module; to do this, they would have to tear off all the fasteners. Place the chisel under the bolt head and tap the chisel with a hammer until the bolt head begins to rise.
- By lifting the threaded fasteners, you can unscrew them - but for convenience, it is better to do this not with your hand, but with prepared narrow pliers - there is a lot of space for standard ones.
- As you unscrew each bolt, try to “catch” the falling module.
- All that holds it is a block of wires. Disconnect it, then install a new ignition module for the Priora car instead of the old one. Tighten the fasteners just as tightly, but try not to tear them off when tightening.
Lock lighting
Illumination of the ignition switch in a Priora car is a convenient modification in the dark. There are ways to tune anything inside your Priora. One of the most practical ways is to help yourself find the ignition switch by highlighting it. But getting a flashlight or phone out takes a long time and is impractical. Instead, you can put a backlight on this part, which will also be aesthetically pleasing to the car owner.
Such an upgrade can be purchased on Chinese websites - preferably only for Priora. To connect, climb under the steering casing, place the LED strip, and the wire soldered to it needs to be “powered.” When connected to contacts No. 8 or No. 9, when the dimensions are turned on, the backlight turns on.
Button instead of ignition switch
As a replacement, the Lada Granta and many foreign car models have a START-STOP button.
We can say that the start button is a matter of driver convenience, but if you want to make your car unique, you can use different options:
- removing the standard module - the steering wheel will not be blocked;
- The standard module remains, but the steering wheel lock does not work;
- The standard module remains in place, the steering wheel lock works.
You can supply a pre-formed kit, or assemble it yourself - it will be several times cheaper, but not faster.
Price
The cost of the set will be from 1,300 to 1,800 rubles, individual parts in total from 300 to 500 rubles.
How to put
To place a button instead of a module, perform the following steps:
- Remove the negative from the battery.
- Remove the steering casing and the plastic panel to the right of the pedal assembly.
- In accordance with the instructions that came with the start button, connect the wires to the block.
- Connect the green cable from the central unit to the brake pedal switch connector.
- The wire from the button should be connected to the three-pin connector of the central unit.
- If you need to disable the steering lock, cut off only the part of the key that fits into the cylinder and leave it in the lock in the first or second position.
- Place the key at the junction of the casing.
- Test the Start-Stop button with a few presses.
The ignition switch is an important element of the car. Without it, the car will not start or drive. If such a part is broken, then it needs to be replaced. A new ignition switch for a Priora in Russia can be purchased for 700-1500 rubles.
What is this?
The ignition switch is a device that transfers energy from the battery to the relay and allows the car to start. This part controls the power supply to the electrical systems and prevents the battery from discharging when the machine is not in use.
The ignition switch consists of:
- Key.
- Contact group.
- Larvae.
- Locking device.
The ignition switch can be called the main element of the starting system of the car's power unit. But such a part is subject to various damages.
Most often, parts fail due to:
- Late machine maintenance.
- Natural wear and tear of individual components of a part.
You can guess that it is time to change the ignition switch by the following signs:
- The key is inserted into the hole with difficulty.
- The core does not turn.
- The steering wheel cannot be unlocked.
- The ignition cannot be turned on.
- The starter does not function.
If the ignition switch fails, it is better to replace it with a new part. Old parts usually have a short service life.
Pricing factors
The ignition switch for a Priora is not an expensive purchase. But all motorists want to save money as much as possible. It must be remembered that the cheapest parts are usually of low quality. Therefore, you should look for a spare part with the optimal price-quality ratio.
When forming prices, sellers take into account the following pricing factors:
- Originality.
- Variety.
- Quality.
- Material of manufacture.
- Company manufacturer.
- The fame of the implementer.
- Place of purchase.
- Delivery price (if we are talking about purchasing goods in an online store).

Brass products are of higher quality and are more expensive.
By the number of contacts there are products:
- Three-pin.
- Four-pin.
- Five-pin.
- Seven-pin.
The most expensive are seven-pin mechanisms.
Ignition switches are also distinguished:
- Specialized(suitable only for a specific car brand).
- Universal(suitable for all types and brands of cars).
Depending on the position there are locks:
- With three key positions.
- With four key positions.
There are details:
- With a key.
- Keyless.
Depending on additional functions, there are devices:
- With steering wheel lock.
- No blocking.
The former are more expensive.
Depending on who the manufacturer is, ignition switches on Priora are:
- Original.
- Unoriginal.
Original spare parts are more expensive.
The new mechanism can be purchased:
- In a store that specializes in selling auto parts.
- At the car market.
- In the online store.
Depending on the brand, the products sold are:
- AvtoVAZ.

- NOKS.
Approximate prices
Russian Priora car owners can purchase a new ignition switch for their car for about 700-1500 rubles.
Approximate prices depending on the manufacturer are given below:
- AvtoVAZ – about 1400 rubles.
- Recardo – about 1000 rubles.
- NOKS about 750 rubles.
Where and what type of auto parts should you buy?
Owners of Priora cars who need a new ignition switch have questions regarding the choice of the type of car part and the optimal place to purchase. Car mechanics are advised to purchase original products from the AvtoVAZ plant. Such spare parts are sold in specialized stores and on the Internet.
But the original is expensive. Therefore, sometimes you have to look for the best option among non-original parts. Such spare parts are sold in specialized stores and at the car market. They are presented by different companies. It is better not to buy little-known brands: such parts are usually of low quality and fail after a short period of time. You should also be wary of buying Chinese counterfeits. It is better to give preference to proven manufacturers Recardo and NOKS. The products of these companies are sold in stores and are cheaper than parts from the AvtoVAZ plant.
Unforeseen car repairs may be required when a key breaks in a domestic car. There are not many people willing to spend time and effort extracting pieces from the larva. Most motorists agree that, for example, replacing the ignition switch on a Priora is a less painful way out of the situation.
Usually, under standard conditions, a key/lock pair can serve for a long time. In practice, they work for 10 years or more. Failure occurs more often due to operating characteristics, and not due to design flaws.
Before changing the ignition switch on a Priora, you must take into account that this operation will be more labor-intensive than a similar process when working with classic VAZ car models.
A motorist can complete this job in an hour. He also needs to stock up on tools:
- Phillips screwdriver or screwdriver with a similar bit;
- hammer 0.5 kg;
- a pointed chisel or punch with a blade width of 8–10 mm;
- hex head 10;
- ratchet equipment with middle extension.
Due to the fact that the repairs are supposed to be carried out in dark, cramped conditions, it is worth thinking about local comfortable lighting. Some find it convenient to work with a car lamp equipped with a hook or magnet for hanging in any conditions. Some motorists are accustomed to using a bright headlamp with LEDs for such purposes.
How to remove the ignition switch on a Priora
Before carrying out work, it is necessary to remove the terminals from the battery. Experts recommend using a proven algorithm:
- At the initial stage, you will need to get rid of the casing that hides the ins and outs of the steering column. The operation is simple and requires only a screwdriver or screwdriver to unscrew threaded hardware.
- The second stage involves unscrewing the special bolts. They are manufactured with tear-off caps and are disposable materials. This design approach provides a certain degree of security, minimizing the possibility of unauthorized access to starting the car. A chisel is used to unscrew them. It is important to remember that they have a right-hand thread.
- Having torn the hardware out of place, you can finally get rid of them using long-nose pliers (curved or straight).
- Remove the clamp. Special bolts held the clamp installed on the steering column. The latter is installed to hold the lock.
- The dismantling work is completed by disconnecting the power plugs in order to have full access to working with the lock.
Next, we purchase a new lock with an immobilizer and relearn it if necessary. Usually you can do it the first time. In some situations, transponders in keys are changed so that the standard protection can recognize electronic signals and unlock in a timely manner.
New lock installation stage
For installation, you will need the bolts used in breakaway fasteners. When a certain force is created, the edges will break off, leaving a head that the classic key will not take. As a result, the clamps will be tightened sufficiently tightly and at the same time receive additional protection.
All four bolts are screwed in the same way with the edges breaking off. The estimated cost of the castle is about 1000 rubles. Most often, special bolts may be included in the kit so as not to purchase them separately.
It is important to know that it is not recommended to reuse old torn hardware to attach the clamp.
A replacement service will cost another few hundred. As a result, by doing everything yourself, you can save money.
Conclusion
The motorist can independently carry out all operations without outside help. The main thing is to have a lock and tools available.
12. ...and remove the contact group from the ignition switch cover.
13. Inspect the ignition switch cover contacts. Clean oxidized or burnt contacts with fine-grained sandpaper. If the contacts are severely damaged, replace the contact group or ignition switch assembly.
14. Assemble the ignition switch in the reverse order of removal, paying attention to the location of the terminals with wires in the wiring harness connector.
15. Install the ignition switch and all removed parts on the car in the reverse order of removal, having first pushed in the locking rod of the anti-theft device. To do this, insert the key into the ignition switch and turn it from position “0” to any other position.
NOTE
When replacing the ignition switch, it is necessary to replace the electronic code elements (transponders) in the ignition key heads of the new lock with the corresponding code elements of the keys from the ignition switch removed from the vehicle.
There is no need to carry out a training procedure after such a replacement.
