Lada Granta electrical diagram: faults


Today we will talk about the reliability of the Lada Grant; the conclusions obtained were based on reviews from car owners.

There are different reviews about this car; in the comments, drivers note both positive qualities and various shortcomings, but on the whole they like the model, and it has every right to exist.

Launched into mass production in May 2011, the Lada Granta passenger car immediately became popular due to its low price and simplicity of design.

The budget car does not have the comfort of limousines, but it is repairable, and spare parts for it are always available.

If you don't take care of the timing drive

Emergency failure most often occurs when the timing belt breaks, and then, perhaps, the matter will be repaired by repairing the cylinder head. All this is provided that the motor is plug-in. This can happen as early as 70,000 km.

The Lada Granta and Datsun mi-DO with eight-valve engines that were used by our editorial team broke earlier than the replacement period stated by the manufacturer. In the car service book, replacement is prescribed at a mileage of 75,000 km. In the end - capital! The same effect can be caused by failed timing belt rollers and a cooling system pump.

To avoid problems, I advise you to check the belt at a mileage of 30,000 km and then at each maintenance. Force it to be changed every 60,000 km.

Is Lada Granta a good car or as always?

By 2011, Granta’s design, although considered modern for the brainchild of AvtoVAZ, was already considered obsolete compared to other automakers. However, for all its unsightly appearance, the car has a very spacious trunk, reliable suspension, low price, cheap components and the boundless love of the Russian people for this car. Availability is perhaps the main advantage of the car and the only reason to buy it.

At the start of sales, three 1.6 engines with 82, 87 or 98 hp were available. With. In 2014, AvtoVAZ released another modification of the Granta - now in a liftback body, with 87, 98 and 106 “horses”.

If you decide to buy a Grant older than 80 thousand km, then check the tension of the timing belt - according to the regulations, it should be changed at 75 thousand. Along with it - a roller, pump and pump. Pay attention to the brand of the replaced spare parts: components for the Lada are cheap, but they last little and often fail before their service life ends. For example, generator bearings often have to be changed, oxygen concentration sensors fail, oil seals leak, spark plugs and coils “die.”

The main thing that Russian cars can boast of, besides competitive prices, is the suspension. No one except the domestic manufacturer knows better what roads cars will have to travel on. The stabilizer struts on the Grant in large cities with relatively acceptable roads change after one hundred thousand km. In the provinces - a little earlier, at 50 thousand. The pads last from 30 to 50 thousand, the discs last twice as long.

Car history

Today, the domestic model Lada Granta is a sales leader. Every year it becomes more and more popular, in demand and interesting to a wide audience, because the car was created using completely new technology, using original design solutions. Engineers have finally begun to move away from the outdated, established stereotypes of automotive design. The result of this search was Granta.

So, at the beginning of the 2000s, the AvtoVAZ plant reminded itself of itself with a good Lada Kalina project. Of course, this car still needed serious improvements and adjustments. But nevertheless, already from this car, new trends in the work of the enterprise emerged, which the press was quick to report and both critics and ordinary car enthusiasts noted. Now the plant management decided to continue the work line that had been started; the next project was to be even more daring, non-standard, combining such qualities as aesthetics, dynamics, comfort and low price.

Initially, the name of the new model was given a lot of words, Low Cost, which translated from English means “low price”. But later it was decided to replace this name with something more sonorous and bright. So, having selected one, Grant, from hundreds of thousands of items, AvtoVAZ began to establish serial production. In 2009, our compatriots saw the first copies of the Lada Grant.

Of course, she was strikingly different from Kalina, and even more so from previous projects. There was no longer that laconic modesty inherent in domestic developments; this car attracted attention with its alluring, elegant forms, an abundance of extraordinary design solutions, and an excellent technical component. It was no longer a shame to show such a car to a global audience, which is what they did.

Granta Sport has repeatedly performed at major international competitions, taking prestigious places. This is how AvtoVAZ’s new idea debuted. But, in addition to the undeniable advantages, there are also flaws in Grant. Here and there there are annoying breakdowns, reminding us that we still have a domestic car in front of us, which is not fully thought out and is still far from ideal.

Salon and trunk

Although the interior plastics are not of high quality, the seats are covered with good material, and they themselves are quite comfortable.

But there is no lateral support in the front seats; the driver’s seat is not height adjustable.

Among the advantages, car owners note the roomy interior; it is quite spacious, despite the small dimensions of the car.

Lada lacks comfort:

  • sound insulation is low, and this drawback is noted by many car owners;
  • not enough legroom for the front passenger;
  • There is no front armrest.

Car owners also pay attention to the fact that the rear doors are difficult to open; sometimes the trunk lid on a sedan does not slam shut the first time.

The lowered door windows rattle at high speed, and the heater motor makes a lot of noise.

Reviews from owners about the interior and trunk of the Lada Grant are still mostly positive; among the advantages, drivers note:

  • spacious trunk;
  • high seating position for passengers in the cabin;
  • modern interior design.

The trunk volume of the Granta sedan is 500 liters; you can place a lot of different luggage here.

And in the liftback, the rear seats fold down, creating a rather large platform, and an adult can even sleep in the luggage compartment.

Lada Granta electrical system: main characteristics

The electrical circuits that supply the engine compartment control systems are designed using a multi-wire circuit and are connected to the vehicle ground only through an electronic control unit.

As a source of energy to power consumers, the standard Lada Granta electrical equipment scheme involves the use of a battery (when the engine is not running) and a generator (when the engine is running).

To connect (switch) the main consumers in the circuit of the Lada Granta car, the electrical equipment is equipped with a combined switch, namely the ignition switch, which in its design consists of a contact part, as well as an anti-theft device.

Disadvantages of restyling Lada Grants of the first generation

Among the shortcomings, the mediocre build quality is noted; the interior panels were already creaking literally a year after the car was put into use, and it is almost impossible to solve such a problem. Another Achilles heel of the Lada Granta restyling is the corrosion protection of the body. Literally 2-3 winters are enough for the car to become covered with rust spots; in such a case, the car owner needs to carry out body repairs, and often the damaged panels are simply replaced with new ones.

The suspension and chassis on the restyled Grant were noticeably improved, but even this did not allow this car to come close in terms of handling characteristics to at least its Korean or European competitors. The Lada Granta is frankly not suitable for dynamic driving on highways; at high speeds it does not keep track well, and acceleration after a speed of 100 km/h is very difficult for the engine.

Many car owners complain about the mediocre sound insulation of the interior, and it becomes uncomfortable not only when traveling at high speed, but even during everyday use in the city. The frankly stiff suspension does not provide the necessary comfort on rough roads, but at the same time it does not need to be sorted out so often. In the restyled model, the design of the stove was changed, the power of which is clearly insufficient in severe frost, which makes it difficult to operate the car in the winter season.

Transmission

The manual transmission has been modernized more than once. It now has a cable drive, thanks to which the gears are engaged with less effort, and the accuracy of the selection mechanism has increased. This box has the factory index VAZ-2181. But the sound when its gears operate is still too loud. The problem with the second gear synchronizer has not been completely resolved. Poor engagement and rapid wear of the synchronizer, despite numerous upgrades, still occur. As well as oil leaks through the seals. The reason is the low quality of the seals themselves and the insufficient accuracy of the positioning of the seal relative to the shaft. All this fully applies to the VAZ-2182 robotic gearbox, because it was created on the basis of a mechanical one.

In the case of gearbox 2181, the clutch mechanism rarely lasts more than 100,000 km, especially if the car is used in a big city and often sits idle in traffic jams. In robotic gearboxes, the clutch lives even less.

The only truly reliable transmission in the line is a 4-speed automatic from the Japanese company Jatco.

Advantages of restyling the first generation Lada Grants

The advantage of the restyled version of the Lada Granta is the affordable cost of this car, as well as the minimal costs of operating the car. The car has a simple and reliable interior; service and repair of the engine or gearbox with suspension are not particularly difficult, so car owners often carry out such work on their own, without contacting a service center. The advantages of this model include good driving performance, an ergonomic interior, and a spacious trunk, especially in the hatchback and station wagon versions.

Lada Granta with engines developing 106 horsepower has good dynamics, which greatly simplifies driving in the city. At the same time, such engines turned out to be quite economical; with a manual transmission, a car consumes 7-8 liters per hundred kilometers in the city, and on the highway the consumption decreases even more. Car owners also note the high ground clearance of this car, so it can be easily used on country roads or in the winter.

The chassis and engine turned out to be surprisingly reliable; the car runs 100,000 kilometers without major repairs. It is not surprising that this car was often used as a taxi. The mechanics do not cause the car owner any special troubles; the oil is filled in for the entire service life of the car, but on an automatic, you only need to regularly change the ATP fluid and the worn out belt once every hundred thousand.

The engine does not start.

Two possible malfunctions: 1. Fuel system malfunction

.
— Fuel lines are clogged. Possibly caused by low-quality gasoline or debris getting into the fuel lines (extremely rare). It is necessary to wash the fuel tank and fuel lines, dry them and fill with high-quality gasoline. It is possible to identify the malfunction by measuring the pressure in the fuel rail, after first making sure that the fuel pump is fully operational. — Fuel pump malfunction. The presence of power can be determined by ear. It should work when the ignition is turned on (do not forget that after 3-4 ignition starts the fuel pump will no longer turn on. Remove it from the gas tank and check it in the tank by turning on the power and measuring the output pressure. It should be at least 2-3 atmospheres. - The fuel filter is clogged. When removing the fuel pump, visually inspect the filter. It may be clogged with dirt, which results in insufficient pressure in the fuel rail. - The pressure regulator in the fuel rail is faulty. On new engines, the pressure regulator can be installed directly in the fuel pump linkage and be located in same housing. In this case, check the pillar assembly. The output pressure should be normal. 2. Ignition system malfunctions
. - There is no spark on the engine spark plugs. The ignition system of the new Granta engine no longer contains high-voltage wires. Perhaps the malfunction arose in the spark plugs or individual coils (break). Replace both with a known good engine. - Throttle assembly is faulty. This is the so-called electronic pedal, which replaces two components of the old engine (throttle valve and idle speed control) with one. In this case, it is an electrically driven throttle assembly. In the event of a malfunction, the composition of the fuel-air mixture may be incorrect, as a result of which the engine will not start. — DPKV is faulty. The crankshaft position sensor counts pulses on the engine crankshaft. If there is no signal from this sensor, the controller does not receive information about crankshaft rotation and, accordingly, does not issue commands to the spark plugs and injectors. — The injectors are faulty. A very rare occurrence, usually one of the 4 injectors fails, but the engine can be started on 3 cylinders. If none of the above reasons solve your problems, then you should contact a specialist.

What is an "engine management system"?

This system is key to the operation of the car. Read more about where it is here!


M74CAN is the “brain” of the Lada Granta car in disassembled form.
It starts and turns off the fuel pump, constantly monitors the volume of air (the air filter is also indirectly involved in this process), which enters the working cylinders, and also directs the same amount of fuel into the intake manifold which is needed at the moment.

In addition, the process of spark formation on the spark plugs is controlled, the ignition timing is adjusted and the frequency at which the crankshaft moves at idle is adjusted.


Engine radiator fan assembly

Additionally, this system controls an electric fan, which is directly related to the engine cooling system. Due to a malfunction in the ECU, the fan may constantly work or not turn on at all.

Disadvantages of Liftback Grants from owner reviews

In addition to the advantages of the new version, its disadvantages were also identified. For example, strong noise in the cabin, associated with both poor-quality insulation and engine operation. The Lux package has reliable sound insulation, but it does not cope with the task completely. Therefore, the owners noted some inconveniences during long driving, especially within large cities.

Problems with unnecessary squeaks were noted by only some drivers. They concern knocks on the driver's door due to poorly secured trim. The rear shelf in the trunk does not knock, but when starting the engine, the hood may rattle and an unpleasant hum may appear. When the speed increases, this phenomenon completely disappears (in this case, you need to check the idle speed. They may be too low).

The small rear window does not allow proper inspection of the road. True, this feature applies not only to the Lada Granta liftback, but also to most other cars in this body. The problem can be easily dealt with by using the side mirrors for visibility. Also a practical solution would be to install a rear view camera.

The overly stiff suspension of the Luxury version does not allow you to fully enjoy driving. The unpleasant phenomenon disappears only when transporting goods or passengers. A similar problem did not affect the Standard and Norma trim levels, although on rough roads they stay on track less well. Replacing the suspension is a very expensive solution, so many owners decided to put up with this phenomenon.

The presence of fairly large gaps was noted only by a small part of buyers. Many of them indicate the appearance of unnecessary sounds due to such equipment of the model. If we look at the problem in more detail, then not all modifications have a perfect assembly. And you should pay special attention to these nuances when purchasing.

The engine runs unsteadily and stalls at idle.

— Insufficient pressure in the ramp. For a description of the solution to the problem, see above in the paragraph “The engine does not start.” — Malfunction of the electronic gas pedal. For a description of the solution to the problem, see above in the paragraph “The engine does not start.” — There is an air leak. The suction is possible through the crankcase ventilation hoses connecting the intake pipe to the vacuum brake booster. Tighten all fastening clamps and, if necessary, replace the hoses with new ones. — Valve clearances are broken. If you have an 8-valve engine, then periodically (every 15-20 thousand km) it is necessary to adjust the timing valves. — Malfunction of the ignition system. For solutions to problems, see above, in the paragraph “Engine does not start.”

Devices for diagnostics of electrical equipment

The set of basic diagnostic instruments includes a circuit tester or voltmeter (although it is quite possible to use a banal 12-volt test lamp equipped with a set of connecting wires). If available, you can use an open circuit indicator, which includes a lamp, an independent power source and connecting wires.

In addition, you should always carry a set of cables in your car to start the engine from an alternative source (usually the battery of another car). These wires are equipped with alligator clips.

It would be a good idea to have an electrical circuit breaker, since this equipment can be used to connect circuit elements and bypass electrical equipment during diagnostics.

Weaknesses of the Lada Granta:

The interior is clearly the weakest side of the car. Already from the first minutes of using the car, you can notice a number of its shortcomings. The first is associated with the handle responsible for adjusting the seat. It is quite fragile and breaks quickly. In addition, the gear lever boot also leaves much to be desired. The material is of low quality and cracks quickly. During operation, it constantly crawls out from under the knob.

Almost immediately, the light that controls the operation of the airbags begins to blink. It indicates their malfunction. Soon the power windows fail. They begin to jam and make an unpleasant sound when the glass is lowered.

The car has air conditioning, but the quality of its operation is quite poor. He doesn't cope well with the task. During the day, in the heat, his work is almost invisible. Especially if the car is stationary.

Lights, electronics, thermostat

The weak point is the rear lights. They sweat quickly and are poorly secured. There are large gaps on the lamp side, where dust and dirt quickly accumulate. It will be necessary to carry out measures to remove it.

As for electronics, it became a drawback on the first cars of this model. Quite often the ECU floods the wiring harness. In addition, generator malfunctions occur. The problem lies with its bearings and belt.

In principle, the cooling system has no complaints. Problems appear only with the thermostat, and not in all models. This problem is mainly typical for cars manufactured before 2012.

Body

The above disadvantages are minor and relatively harmless. If we talk about the body, then this is a serious disadvantage of the vehicle. The paint on it wears off quickly. As a result, the body is left without a protective layer and begins to rust. This indicates that the vehicle was installed incorrectly. At the same time, the plastic bumpers are not painted at all, which many buyers do not really like.

Chassis, gearbox, brake pads

The car's chassis became its important drawback. Over time, the front struts begin to make an unpleasant sound. It manifests itself in the form of a knocking sound after 6 thousand kilometers. Over time, the traction control brackets located on the front suspension can burst.

The appearance of a whine in the gearbox indicates a malfunction of the gearbox. This problem often worries car owners. In addition, when cold, this part has a tight movement. It does not tolerate low temperatures well. In winter, there is a high probability of the handle freezing. This problem can be solved by simply changing the gearbox oil to synthetic.

The brake pads that the Lada Granta is equipped with are of low quality. Over time, they make an unpleasant creak and squeal. In addition, brake discs wear out quickly.

The handbrake cable is not very well secured in the car. Experts advise starting to operate the vehicle with extreme caution. It will take time to get used to this feature.

Body corrosion is an integral part of Grants

Almost all Lada Granta owners are faced with body problems that lead to the need for constant repairs, touch-ups and restoration. If you miss the moment when rust began to spread in your car, it will be extremely difficult to correct the consequences or stop the corrosion. The body of the Lada Granta is not protected from corrosion at all from the factory, even though such an item is included in the package. Many owners speak in reviews and interviews about the following problems of the domestic bestseller:

  • in the first year of operation, the car requires body work, unpleasant moments, pockets of rust and other problematic areas appear;
  • the quality of painting is very low, new chips and scratches constantly appear, which even arise from contact with bugs on summer roads;
  • traces of corrosion appear under the plastic elements of the body, rust appears very quickly above the wheel arches, at the bottom of the doors and on the sills;
  • when a source of corrosion appears, the spread occurs incredibly quickly, this significantly reduces the service life and potential life of the vehicle;
  • The attractiveness of a car decreases over time, chips and scratches, poor-quality paint make themselves felt in the form of dull and damaged parts of the car.

Of course, no owner of such a car will like such problems. Domestic traditions remained relevant for this car. We all remember what body problems there were in the Tens. They were inherited by Grant, which, if left uncared for, can rot in just a few months. This car needs to be additionally treated with anti-corrosion materials, and you should also think about painting with more expensive technologies a few years after purchasing the car.

Main types of faults

So, as you can see, there are more than enough places for potential breakdowns. In case of errors, the “check engine” indicator will light up on the instrument panel screen.


This is what the engine warning light icon looks like

All engine modifications of the Lada Granta are controlled by an electronic control system.

Problems with the fuel pump


Location of the fuel pump in Grant (I apologize for the dirty interior, there were rogue kids driving before the shooting)

In this component, two parameters must be monitored, among which the operating pressure, as well as performance during operation, stand out. In most cases, the problem can be resolved through repair work rather than completely replacing the part.

First, you need to check the voltage at the connector that supplies power to the gasoline pump. This comes from the on-board energy system. If possible, this value should be 12 V or even slightly higher. In addition, during operation, slight noise during operation of the pump is considered normal.

The difficulty with this testing method lies in the fact that it can be very difficult to detect an unreliable contact in an electrical circuit on the way to the connector.

If we talk about control relays, then they are all located inside the car. And, if they do not work correctly, they can give themselves away with characteristic clicks. But, this malfunction is quite easy to fix, since replacing the relay is accompanied by monitoring the symbols, which will tell you where and what component needs to be mounted.

Problems associated with starting the Lada Granta engine

Naturally, many other problems are possible that are directly or indirectly related to its management system. These include wear on the injection elements of the fuel pump. Problems may also relate to the fuel supply process, as we already discussed in the previous section.

Reviews from owners Grants liftback: special advantages

The high-quality optics of the car have won the hearts of many owners. Grant owners note the good illumination of the roadway, which is especially important for increased safety.

There were no complaints about operation or malfunctions due to strong vibrations. Stylish taillights allow cars driving behind to see the moving Lada from afar.

Buyers of domestic cars carefully study the performance characteristics that allow them to purchase truly high-quality vehicles. For the stylish and comfortable Lada Granta liftback, owner reviews touched on the high ground clearance.

The clearance is 16 cm, which is quite a lot for such a nimble model. It is more than possible to drive through complete off-road conditions without damaging the bottom of the car or getting stuck in a deep rut. In addition, an important advantage of such clearance is the ease of travel at any time and on any site.

Interior comfort is another factor in the search for a workhorse. If we take into account the use of transport in winter, then it is worth paying special attention to the stove. Granta Lada, according to drivers, has one of the best heating systems. It quickly heats up the interior, so there is no need to worry about the stove taking a long time to start.

Also, the purchase of Granta liftback pleased the owners with cheap service. For the most part, small parts that do not require special costs fail. Moreover, repairs during the warranty period are carried out not only in a minimum of time, but also completely free of charge.

You can install not only original spare parts, but also some elements from its progenitor - Lada Kalina. This makes it much easier to find the item you need.

The engine does not develop full power.

— The engine is new, has not yet been run-in. The new Granta engine needs an initial run-in of up to 6-7 thousand km. During this period, the engine does not develop full rated power. The crankshaft revolutions during the break-in period should not be raised above 3000. — Malfunction of the electronic gas pedal. For a description of the solution to the problem, see above in the paragraph “The engine does not start.” — Insufficient pressure in the ramp. For a description of the solution to the problem, see above in the paragraph “The engine does not start.” — Valve clearances are broken. If you have an 8-valve engine, then periodically (every 15-20 thousand km) it is necessary to adjust the timing valves. — Malfunction of the ignition system. For solutions to problems, see above, in the paragraph “Engine does not start.” — Low compression in the cylinders.

Insufficient oil pressure.

1. Using oil that is not suitable for the engine. Use only oils and specifications recommended by the manufacturer. 2. Oil dilution/foaming as a result of fuel/antifreeze entering the engine crankcase. It is necessary to identify leaks and eliminate them. After this, be sure to replace the oil with a new one, with flushing. 3. Worn oil pump. The oil pump resource is quite long. Its failure is rare. If damaged, replace with a new one. 4. The oil filter is clogged. Replace with a new one, along with an oil change. 5. Damage to the crankcase. Check for external damage to the engine crankcase. It may be damaged by the road surface, which will reduce the gap between the oil receiver and the bottom of the oil sump. 6. Clogged oil channels and lines. May be caused by contaminated oil over a long period of time. The system needs to be flushed. 7. Cracks, uninstalled oil channel plugs. Carry out a visual inspection and install missing plugs.

Creating a model

Modern Lada

The Lada Granta was intended to replace not only the latest model of the “classic” VAZ 2107, but also the Lada Kalina, which, as many believe, turned out to be a marketing miscalculation of the Russian automobile manufacturer. However, it was the Kalina platform that became the basis for the design of the new car.

The developers set themselves a goal: to make a car that was budget-friendly but attractive in appearance. The designers changed Kalina's body greatly, and the created forms turned out to be exceptional for VAZ. The new model of a class B vehicle has very decent dimensions: length - 4260 mm, width - 1700 mm, height - 1500 mm, ground clearance - 170 mm. It is available in “standard” and “luxury” trim levels. Lada Granta is the first series of domestic cars produced with an automatic transmission (luxury equipment).

Electrics and body

The generator bearings have insufficient life. They can begin to hum by 80,000 km. Power windows often squeak and raise the windows slowly due to glass jamming in the seals. Electric window motors often fail. You can also note the leakage of the rear lights of sedans: not only water, but also insects penetrate inside.

The paint on the body can be easily damaged by stones flying from under the wheels of other cars. The resulting paint chips “bloom” quite quickly. The paint layer is so thin that it is sometimes rubbed off by the door seals. The seat adjustment knob often breaks off.

Technical disadvantages

Operation of the new Lada Granta model in a short period made it possible to identify a number of design and technical flaws and weaknesses in the car and characteristic malfunctions of the car. What might a Lada Granta driver not like initially?

  • The appearance of a car with a sedan body cannot be considered harmonious and proportional from all angles and colors. But this is a matter of taste.
  • There is no engine temperature sensor on the dashboard. Despite the general tendency in the global automotive industry to replace such an indicator with a conventional LED indicator, it is necessary to take into account the climatic features of the large territory of Russia. Here, not only engine overheating is important, but also its current temperature, for example, at the initial stage of operation.
  • Creaking body. On some examples of the car, assembly (or design) flaws begin to appear almost immediately. This is especially true for driving on dirt or country roads and when the road surface is damaged.
  • The absence of ceiling handles, although not an obvious miscalculation, deprives passengers of an additional point of support and once again indicates the budget class of the car.
  • Hard plastic in the interior decoration of the Lada Granta. Although this decorative element is made to last - there are no burrs or wide cracks - over time, all the weak points of the interior begin to creak. This is not so noticeable in comparison with other models, but the number of parts for the central part of the car is smaller here, and there are not so many contact points where squeaks could appear. One of the possible reasons for excess sound in the cabin could be the car windows, which is a sign that their installation in the door seals is not airtight enough.
  • Incorrect operation of the climate system. Its rather high efficiency is manifested by an unexpected stepless transition from cold to hot mode, which has a negative impact on the interior materials. Changes in shape, distortions, and swelling of materials on the A-pillars and roof are observed.
  • Installing a conventional fuel filler cap.
  • Adjusting the headlights involves using a hydraulic corrector instead of the previously used electric one on the earlier model, Lada Kalina.

The second group of shortcomings includes assembly features, which also cannot be classified as positive manifestations of a new car. From these positions, the Lada Granta showed itself in such cases.

  1. Severe fogging of the optics of external lighting devices and car windows. The reasons for such manifestations can be either blockage of ventilation ducts or leaking devices.
  2. Plastic pipes of the air supply system and engine cooling system can be prematurely damaged due to strong clamping with fastening clamps at the mounting points.
  3. The steering of the Lada Grant is not entirely clear. If it is in full technical condition, a certain amount of play in the steering wheel can be noted, which is more likely due to unstable operation of the engine than to the presence of mutual movement of the mechanism parts.
  4. If door handles are used carelessly, they do not demonstrate the required reliability and durability.

Malfunctions of electrical equipment in Lada Granta - a guide to action

Although the car has a fairly reliable electrical system that powers consumers, from time to time electrical equipment malfunctions still appear on the Lada Granta.

Before you begin troubleshooting any faults in an electrical circuit, you should carefully study a specific electrical circuit diagram in order to understand the functional purpose of such a circuit as clearly as possible.

Potential fault locations are usually eliminated by identifying and eliminating properly functioning components of the same circuit.

In the event of simultaneous failure of several elements or circuits, the likely cause of failure may well be the blown fuse responsible for these elements. The cause of electrical equipment malfunction in a Lada Granta car may well be a violation of contact with ground.

Failures of electrical equipment are very often explained by the most elementary reasons, among which the most common are:

– corrosion of contacts on connectors; – failure of the safety element; – burnout of fuse links or damage to contact groups and relays.

You should visually check the functionality of all fuses, wiring and connectors in the circuit immediately before proceeding with a more scrupulous check of its components.

If you use diagnostic devices to find a breakdown, plan in detail exactly which points of the circuit circuit and in what sequence (the Lada Granta Norma electrical diagram will help with this) you need to connect the measuring device for more effective detection of the fault.

Other childhood diseases Lada Granta

According to reviews, you can find dozens of other car diseases that owners have to actively treat in order to operate their car normally. These diseases are not only the causes of factory defects, but also underlying problems of saving money on a car. Often problems in Grant arise due to poor quality service or a problem that was not corrected in time. Among the additional diseases of the machine are the following features:

  • faulty wiring and terrible performance of the multimedia system are two problems that are closely related and require professional intervention;
  • After 50-70 thousand kilometers of travel, the manual transmission begins to howl furiously and in every possible way communicate the need for attention, even with normal maintenance;
  • Regardless of the quality of work and condition, the front struts of the Grants constantly knock and create not the most pleasant sensations from operating the car;
  • The on-board computer is a separate story for the Lada Granta, which is a real problem for the manufacturer on all cars.

You can continue the list of popular problems and reasons for contacting the service. Therefore, you should not be under the illusion that the Lada Granta car is of incredibly high quality and the best in the history of the domestic automobile industry. Don’t rush to draw conclusions, read reviews, take a test drive. But this does not mean that you should not buy a car. Where else can you find a new car for 350,000 rubles with good equipment and a fairly comfortable ride? We invite you to see a short review from the owner of Lada Grant about his car:

conclusions

Most of these problems are caused by improper operation of the vehicle, including the use of low-quality fuel and oil, as well as prolonged operation at high speeds. It would be a good idea to carry out preventive maintenance from time to time to identify shortcomings in the form of leaks in the fuel channel, where air can get in.
