At the end of the work, all the wires are successfully hidden behind the carpet and thermal insulation. Therefore, this type of work will not affect the visual appearance of the salon.

What functions does the block provide?

The main functional purpose of the device is to monitor and control the electrical system in the car. Some important functions for which the block is responsible:

• fog lights, low beam, side lights;
• lighting in the car interior;
• direction indicators;
• power window system;
• operation, adjustment and heating of side mirrors;
• anti-theft system;
• signaling;
• door locking;
• trunk lighting;
• instrument panel lighting.

Partial, and even more so complete failure of the unit causes significant trouble for any car owner. The biggest problems are caused by the failure of the comfort unit in dense city traffic conditions.

Electromagnetic relay

An electromagnetic relay is a switching device designed to relieve contacts. The work is based on the law of electromagnetic induction.

In cars, relays are used to unload contacts on control buttons, so that they, in turn, do not melt or heat up when more current appears on them. The relay consists of moving and non-moving contacts, a DC coil, a return spring, a coil core and an armature.

Relay operating principle

When a current appears on the relay coil, a magnetic field is formed in it, which in turn begins to attract the armature to which the movable contacts of the relay are attached. As a result, the moving contacts close with the fixed ones and the electrical circuit is completed.

Malfunctions in the operation of the comfort unit, how to eliminate them

1. The turn signals do not light up. First, you should check the continuity of the fuse, lamps and steering column switch. If there is simply no contact somewhere, then the problem can be resolved very simply by resoldering the microcontacts. If there is a fault in the board itself and soldering the contacts does not help, then the controller should be replaced.
2. The power window module or central locking does not work. This problem can also occur due to oxidation of the wires. Before removing the comfort unit, you need to check all the wires with a multimeter under the insulation in the control unit, which is built into the driver's door. If only one glass unit is faulty, the wires could become disconnected due to a broken contact.

After checking the wires, if the problem cannot be found. The DA7VN5016A or DA6VN5016A controller should be re-soldered. One of them is responsible for the double-glazed windows and the lock on the right door. The second mirrors the same functions, but on the left side.

Sometimes window lifters only work to lower the windows, but raising them is not available (or vice versa). To do this, check the connection so that all the pros and cons are in place.

Errors occur in the comfort unit when the window lift button to raise the window works to lower the window. With different polarities, when the glass rises instead of lowering, you need to change the connection of two adjacent wires.

1. It happens that many problems arise at the same time. The fog lights, side lights, rear lights, heated rear glass, and interior light stop working. In this case, it is obvious that the problem comes from the comfort unit and the DA1 MC33972EW variant is re-soldered. If this does not help, then the entire circuit should be replaced.
2. In case of failure of the rear fog lights and instrument lighting in the cabin, the DA9 VND5025AK component is re-soldered. And, as was the case with previous breakdowns. If this does not bring results, the entire scheme is changed.
3. The central locking locks begin to operate when the power window keys are pressed. If replacing the comfort unit from another car does not bring any effect, then the essence of this breakdown is in the wiring. To do this, you need to carefully check the integrity of all wires leading to the comfort unit.

Possible causes of malfunctions

Before purchasing a new comfort unit, you need to try to eliminate any malfunction. In order not to make additional costs, because the comfort unit is quite expensive. Often the problem is simply a lack of contact due to aging or chafing of the wires.

Sometimes the comfort unit controllers can burn out, for this you need to inspect them visually or even check them using your sense of smell.

The most common complaints regarding the operation of the comfort unit are the failure of double-glazed windows, turn signals or dimensions.

All problems can occur due to the following events

• break on the W-Line communication line;
• combustion of regulation drivers;
• burnout of controllers responsible for the desired area;
• transponder malfunction;
• burnout or oxidation of contacts.

Before carrying out repair work, to comply with safety precautions, do not forget to disconnect the negative terminal from the battery.

How to change the bulbs in the headlight of a VAZ 2170

To replace the low beam bulb, wear clean gloves and disconnect the battery.

Then remove the rubber protective cap, which is located closer to the fender.

Carefully disconnect the wires.

• Remove the latch (to do this, press down and remove it from behind the hooks).
• Remove the lamp and install a new one. Installation is carried out in reverse order.

Replacing high beam bulbs is no different.

If you frequently drive at night, especially in bad weather, make sure you always have a spare set of light bulbs in your car. Probably every driver has experienced the fact that one lamp burns out at night and the lighting becomes much worse. You also endanger other road users, since it is difficult to assess the situation during the same overtaking when one of the headlights of the oncoming car is not on.

To replace the bulbs in the rear light, you will need to dismantle it. (see Replacement of the rear light)

Remove the taillight and turn the parking lamp (in the Priora, the parking light is combined with a double-filament fog lamp).

Remove the lamp by turning it counterclockwise.

Install a new one. Make sure that the tabs on the plinth fit into the grooves on the parton. All other lamps are changed in the same way.

To replace the rear license plate lamp on a Lada Priora you need:

Remove the lock trim.

Unscrew the trunk lid attachment, which is secured with 4 bolts

Remove the socket and change the light bulb.

If you cannot remove the cartridge itself, remove the flashlight itself

To do this, you need to bend the plastic clamp a little (Caution, they are very fragile). After this, you can apply a little more force to unscrew

Install everything in reverse order

If you want to change the trunk light bulb, then:

Pull the lantern out of the opening as in the picture below.

• Bend the antennae that hold the lamp and change it.
• Reinstall the lantern in its original location.

At this point the repair can be considered complete. Connect the battery and check operation. If the replacement does not help, then most likely you should check the wiring.

Where is the Priora comfort block located?

To gain access to the product, you will need to unscrew the protective plastic walls of the car's center console. They are located on the left side of the front passenger seat and on the right of the gas pedal, on the driver's side. The device itself is located above the control unit. In order to remove the device you will need a 10 mm wrench and a Phillips screwdriver.

Pinout of the Priora comfort block

The main, important elements of the device are:

1. The so-called control drivers. Each driver is responsible for a set of specific functions.
2. Transponder receiver.
3. Relay control.
4. Transceiver. Communicates with the module installed in the door.
5. 2 connectors. The first is responsible for supplying power, the second for transmitting the necessary technical information.

Click to enlarge

To ensure proper operation of all elements connected to the comfort unit connectors, it is necessary to study the correct pinout (numbered diagram for connecting wires to contacts). The design of the comfort block for the Priora, when studied in detail, is not particularly difficult.

Electrical unit pinout

The elements included in the electrical unit package are divided into the following components:

• drivers, each of which has its own function and is responsible for a separate section;
• relay coordination;
• transponder receiver;
• the transceiver is involved in the connection with the door module;
• two connectors for transmitting electricity and necessary engineering information.

When familiarizing yourself in detail with the diagram of the distribution of wires by numbers (pinouts). Working with the Priora comfort unit will not be particularly difficult.

Each contact in the diagram is described separately, which is important for understanding all operational problems. The Lada Priora comfort block diagram is present in the technical manual for the car.

Possible malfunctions and ways to eliminate them

What malfunctions may occur in the operation of the electrical package controller:

1. Turn signal failure. First of all, you need to diagnose the serviceability of the fuse, light bulbs, and the steering column switch. It is quite possible that the contact in the switch itself is broken; the problem can be solved by resoldering the contacts or replacing it. If this does not help and the problem really lies in the board, then there are two options - either resoldering it in accordance with the diagram, or replacing it. Usually, soldering is done first, and if it does not help, then the controller itself is changed.
2. The power windows don't work. Before getting into the circuit, you need to make sure that the problem does not lie in other elements. As in the previous case, first check the fuse, and then diagnose the power window control unit, it is built into the driver's door trim. If only one window regulator does not work, then most likely the contact on the unit has simply come loose and needs to be reconnected. Sometimes the problem lies in a broken or broken wire, in which case the circuit needs to be restored. If this does not help, then the DA7VN5016A or DA6VN5016A controller is resoldered. The first is responsible for the operation of the power windows and central locking on the right doors, and the second is responsible for the same elements, only on the left door. Both elements are marked in the diagram for clarity. The problem with the central locking is solved in a similar way if it does not work. Also pay attention to the DA11L9848 controller - it is responsible for the operation of the lift control relay. So if the relay does not work, but the contacts of its seat are intact, then perhaps the problem lies with this controller.
3. At the same time, the side lights, front and rear fog lights, interior lights, reversing lights, and the rear window heating system stopped working. If these components stop working at the same time, then there is no doubt that the problem lies in the electrical package control unit. In this case, the DA1 MC33972EW controller is resoldered, since it is he who is responsible for the operation of these components. If resoldering does not help, then the entire circuit changes.
4. If the rear fog lights and the dashboard lights do not work, then most likely the culprit is the DA9 VND5025AK controller. You can also try to re-solder this component, but if re-soldering does not produce results, then it will need to be completely changed.

Features of stove malfunctions

Lada Priora: fuel pump fuse and its features

There are several special breakdowns that are visible, figuratively speaking, to the naked eye. These are usually the following problems:

• Heater radiator.
• Stove fan.
• Damper.

They are usually diagnosed without the use of a computer. For example, a leaking radiator clearly manifests itself as a sticky residue when blowing on the windshield, a strong smell of coolant in the cabin and, of course, a decrease in the level of coolant in the expansion tank. The fan simply stops spinning in all positions of the control handle.

Well, the damper. When switching air temperature modes, you can hear the drive operating, but the flow does not change the degree of heating. This means the damper is broken.

Self-repair of the Priora comfort unit, is this possible?

If you have never encountered soldering, diagnostics of printed circuit boards of varying complexity and configurations, or do not have the necessary diagnostic or soldering equipment, then it is better to address the repair question to qualified specialists. If you have the above skills and understand the causes of malfunctions, independent repairs are carried out quite often. This is due to the fact that various microcircuits or chips constantly fail. For example, having established that the reason for the turn signal failure is a failed control driver, it is always possible to purchase a new part and simply re-solder it to replace the faulty one.

Malfunctions and their possible causes

The cost of a new, original unit is quite high, so do not rush to buy a new product, figure out the causes of the malfunctions. Of course, there are always cases when the board cannot be repaired and it is more advisable to simply install a new product to replace the faulty one. Do not forget that the causes of malfunctions can be frayed or broken wires that are connected to energy consumers.

According to statistical data collected on technical support forums, car owners quite often complain about malfunctions in the operation of power windows, turn signals, and parking lights.

If we talk about the components of the printed circuit board itself, the most common breakdowns are associated with: - a break in the W-Line communication line; — burnout of control drivers; — burnout of controllers responsible for correct operation; - the output of their transponder; — significant oxidation of contacts.

"Important! Before carrying out any electrical work, disconnect the power supply by disconnecting the negative terminal of the battery."

Fuse

A fuse is an electrical switching device designed to protect electrical circuits by breaking the circuit due to its destruction or shutting down when a current flowing through it exceeds the permissible values.

Fuses come in several types and are used in all electrical circuits to protect vehicles from short circuits (short circuits). They are classified according to the rated current of the fuse link.

The fuse link is the part of the fuse that is destroyed by electrical current.

The rated current is the current of the fuse at which the fuse-link will operate indefinitely and will not be subject to destruction.

Operating principle of the fuse

When using a fuse in an electrical circuit, the operating current passing through the fuse does not exceed its rated current - this is its normal operation. But as soon as a current appears in the electrical circuit that exceeds the safe permissible values ​​​​in this circuit, regulated by the fuse, the fuse-link, under the influence of a current exceeding the rated current of the insert, begins to melt and collapse as a result of which the electrical circuit breaks.

You can restore the electrical circuit by replacing the fuse, but only after the culprit for the increased current in this electrical circuit has been found. Otherwise, the new fuse will also blow.

Schematic diagram (pinout) of connecting the front wiring harness on the Priora

The front part of the vehicle's electrical circuit is designed to supply voltage to the primary and auxiliary power circuits of the vehicle's on-board systems. The decoding of contact group chips is as follows:

• 1 – starter power supply;
• 2 – battery;
• 3 – charge supply from the generator;
• 4 – connecting block for the bundle (1 – 3);
• 5-7 – power supply to the device;
• 8 – engine compartment lighting lamp;
• 9-10 – head light;
• 11 – brake expansion tank level indicator;
• 12 – outside temperature;

Glass closer Pandora DWM

Connection diagram for the passenger door button in series through a duplicate button on the driver's door. Contacts 1-6 and 7-3 are always normally closed. When you press the up button, contacts 1-6 open and 1-2 close (window rises). When you press the down button, contacts 7-3 open and 7-2 closes (window down). The 30th contact of a 5-pin relay, without supplying voltage to the winding contacts, is constantly shorted to contact 88, which gives us the necessary negative contact (works like a switch). If voltage is applied to the winding, then contact 30 is disconnected from contact 88 and connected to contact 87. Contact 86 of the winding is connected to ground.

Types of compatible window regulators

One of the most common models on the aftermarket is the window regulator for the Priora Forward. This model of electric lift is made in a combined arrangement of the drive and the actual rack-and-pinion lifting mechanism, compactly combined with the glass guide. Lifts of this model are characterized by increased reliability and ease of installation on Priora.

Garnet is the second most popular system. Under this name there is not even a single model, but a whole family, each modification of which is intended for a specific car. The mechanism is also rack and pinion type and has earned many good reviews from car enthusiasts. This type of lifts is characterized by uninterrupted operation, fast speed of raising/lowering the glass, and low noise.

It has already been said above about glass closers. In the luxury package they are available on all doors, but their performance leaves much to be desired. It is necessary to resort to replacement with other similar devices. One of the available alternatives is the Master system. It allows you to automatically raise the windows when the anti-theft system is turned on, and even control them within half an hour from the moment the ignition is turned off. The device itself looks like an electronic board with connectors connected to the standard Priora wiring.

The master is not very expensive (from 700 rubles), and its installation does not affect the door trim in any way. The whole procedure consists of removing the rear door sill trims, bending the sound insulation and connecting the door closer to the connector.

For the front doors, the Master will by default raise and lower the windows without ignition, and for the rear doors you need to install a slightly different version, called Master Plus. There are no differences in installation, the main thing is not to forget to disconnect the negative battery before starting work. The wizard has many other useful functions, for example, it automatically turns off the radio when the car is armed.

How to enable self-diagnosis of the instrument panel

On-board computer staff Priora matrix instead of a clock in the console from the Lada Priora
Using the panel you can “dig into the brains” of the Priora:

1. Hold the button under the fuel gauge and turn on the ignition. The display should indicate the start of the test.
2. Press the button again. The display should show the operating system version.
3. Click again. The system should show error codes:

• (2) – High voltage level;
• (3) – DT malfunction;
• (4) – DTOZH malfunction;
• (5) – DTV malfunction;
• (6) – Motor overheating;
• (7) – Low oil level;
• (8) – Malfunction of the brake system;
• (9) – Battery discharge;
• E – Brain error, EEPROM.

1. If necessary, reset the error: hold the button for three seconds.
2. Release the button. Click again. All indicators should light up.
3. Leave all the buttons. After 30 seconds, the self-test will automatically complete.

The dashboard contains the following parts, without which the car would not function:

• external lighting controller;
• switch for turning and lighting headlights;
• signal regulator;
• instrument cluster;
• wiper regulator.

Location of the comfort controller in the cabin

You need to know that there are two options for the location of this device:

1. On the first Priora models it is under the beard.
2. On subsequent ones, to the left of the mounting block.

When these cars appeared, the comfort unit was installed in the area of ​​​​the electronic control unit. That is, under the “beard”. If you open the decorative plastic cover located at the passenger’s left foot, you will see the Priora control unit with attached relays. Directly above them is a comfort unit (electrical package).

On subsequent cars this unit was positioned slightly differently. At the driver's left foot, with the instrument panel cover removed under the steering wheel, there is a fuse and relay assembly. Or - a mounting block. And behind it, at the wall of the body, the electrical package is mounted. Access to it is quite difficult.

Removing the comfort block on new models

If you follow the manufacturer's technological instructions, this is a very complex and time-consuming process. Suffice it to say that according to this scheme it is necessary to partially dismantle the entire dashboard of the Priora. Of course, experienced locksmiths do not do this. The process goes as follows. The negative terminal of the battery is removed.

After this, remove the decorative panel under the steering wheel. It is secured at the bottom with 3 plastic swivel fasteners. The mounting block will become available. Now comes the most difficult part. You will need a 10mm bell key. This is the most convenient option for this job.

You'll have to climb and grope with your hand. As already mentioned, the electrical package controller is screwed behind the mounting one. It is perpendicular to it. It is secured with two bolts

heads 10. Before unscrewing them, you need to disconnect the three wiring harnesses connected to the block. It is not difficult. And it is impossible to confuse them during installation. They have different entry options. After this, you can remove the mounting bolts. Since the ears on the device are not closed, but have a free exit, one of the bolts can only be loosened 3-4 turns. And then take out the block.

Install the new one in the same way.

Replacement on the first Priors

This is generally a simple operation. The shield is removed from the bottom of the “torpedo” on the passenger side. The comfort controller is perfectly accessible. Unscrew the fasteners in the same way and remove the device. Replace with new one. The only thing is that the wiring harnesses are on the driver's side. But it is just as easy to remove the side panel, which is secured with 1 bolt.

Location on newer models

Once you have disconnected the negative terminal from the battery and made the disassembly process safe. Disconnect the decorative protective cover located under the steering column. To do this, you need to release three mounting fasteners using a 10mm wrench.

In this case, the comfort block is located behind the mounting block. And you will have to act by touch, which is what car mechanics are used to doing.

Before removing the unit, you need to disconnect the three electrical harnesses from the wires. The fastening mechanisms should not be unscrewed completely. But only turn it 3 or more turns, since they have an open circuit. Then you can remove the block itself.

The main functions performed by the electrical package control unit (comfort unit)

In fact, this device is a multifunctional control computer. His responsibilities include ensuring the functionality of many Priora functions:

• Electric windows.
• Adjusting the side mirrors.
• Turn and hazard warning lights.
• Anti-theft system.
• Door locking from the driver's door remote control.
• Lighting module.

So many options require precise operation of the Priora comfort controller.

How to disarm the electrical package unit of LADA PRIORA

What to do if Priora is not removed from the standard alarm!

The hazard warning light blinks, the car does not respond to the ignition key buttons. As a rule, several units are involved here that are synchronized with each other.

1. Ignition
2. Radio channel module (Located in the driver's door)
3. Electrical package block (Comfort block)
4. Engine ECU

New blocks come with non-activated codes inside and can be installed on any car without problems, but once you register (train) the keys, a special code is written into all these blocks, which is synchronized with each other and serves as a standard alarm system. (Immobilizer) As soon as you turn the ignition key, within five seconds there is a poll between the key and the units, if the code matches everywhere, then the engine ECU gives permission to start, if the code of at least one device is not recognized, the engine ECU is blocked and the car does not start.

Training a working key is done using a special red training key. I will not describe the procedure for training keys; there is plenty of information on the Internet. In fact, the main key is a red training key; it stores a code that, after training, is written into the working key and other blocks.

I'll try to explain in more detail how it all works:

• The radio channel code that we use to open doors using the key's remote control buttons is written into the driver's door module, where the power window buttons are located. If you replace the comfort unit or engine ECU, the buttons on the key will still work.
• The IMMO (Immobilizer) code has a connection only with the ignition key, the electrical package unit and the ECU unit. If you disconnect the driver's door module, the car will still start.

How to determine whether the keys are trained or not:

• The IMMO lamp on the instrument panel goes out after 5 seconds - the keys are trained.
• The IMMO lamp goes out after 30 seconds - the keys are not trained. (The car will start with any blank)

Options for disabling IMMO:

• Write an untrained eeprom dump to the engine ECU. All functions will remain working as normal, key buttons, etc., only the car will start with any blank.

If the vehicle cannot be disarmed using the remote control:

• Here the situation is a little more complicated, this is why this article was written. Suddenly, for some reason, the car remained on guard, the hazard lights blink, the car beeps, etc. Of course, you will open the car mechanically using the keyhole in the door, but at the same time constantly The hazard warning lights blink and the comfort functions do not work, and the car does not start. The reason could be a breakdown of the remote control key or the driver's door module. However, the electrical package unit remained armed.
• There are two ways to disarm the electrical package unit: 1) Install the driver's door module from another car and open it remotely from the key of the same car. In this way, you can disarm the comfort unit. 2) Disassemble the electrical package unit and use the programmer to clean the M95080 memory chip.

Replacing the Priora comfort unit

Before purchasing a new product, you must be sure that the cause of the malfunction lies precisely in it. To do this, you can install a known-good unit in your car and test the operation of problematic units. If, with a new, serviceable device, electrical consumers operate normally, the old comfort unit is faulty. Otherwise, use an integrated approach, check fuses, relays, wiring, and all kinds of drives. In other words, the entire technical chain with which the faulty unit usually comes into contact during operation.

Replacement of the device is carried out in 7 simple steps:

1. We put the car on the parking brake.
2. Open the hood, loosen the negative terminal and remove it from the battery.
3. We move into the car interior. For ease of operation, we roll the front seats back into the cabin as far as possible.
4. We prepare the tool. Using a screwdriver, unscrew the mounting bolts and remove the 2 side walls.
5. Using a 10mm wrench, unscrew the two fastening nuts.
6. Carefully remove the block itself. When removing, rotate the product so that it does not hit other elements. Disconnect two contact connectors, the first is power, the second is information.
7. Remove the faulty product and install a new one.

In the future, in order to inspect, diagnose or repair the Priora comfort unit, you will need to remove its protective housing. When purchasing a new unit, keep your sales or sales receipt. If you purchase a faulty device, this will allow you to return or exchange it for a new one. Prices for the product vary depending on the specific seller and range from 2,500 rubles to 10,000 rubles.

Installing rear door lifts

Electric windows are a necessary element of comfort. But with Priora everything is not so simple. Standard wiring (unless, of course, you have a luxury version) is not enough to install lifts in the rear doors. And the first thing you have to do is stretch the necessary wires from the control unit to the doors. Moreover, this is not the only difficulty. On some versions without rear ESPs, relays for them are installed, and the control unit has only 2 buttons. Thus, in order to install the lifts back, you need to change the control unit to a four-button one.

When replacing the unit, problems may arise with the immobilizer of the standard anti-theft system. It must either be deactivated or reprogrammed. It depends on whether you want a factory alarm. In general, the procedure, which in itself is not too complicated, becomes more and more complicated in Priora trim levels other than the luxury one.

In order to install electric windows on a Priora, you will need a set of keys, the lifts themselves and a screwdriver. Time spent from 15 minutes on the door without taking into account fiddling with the immobilizer. In some cases, up to five hours of work will be required.

But even a seemingly correct installation does not guarantee that the Priora’s power windows will immediately start working.

The Priora has a rather complex wiring diagram, especially for those who have not done any manipulations with it before. And if there are no relays in the rear doors yet, you will have to purchase and install them.

By the way, it’s easy to check their presence: when you use the window regulator on the front door, quiet clicks will be heard in the rear ones. These are working rear relays, quite suitable for installing non-standard ESPs compatible with your car. There is some information on this issue on car forums.

You also need to know how to remove the lift to replace or repair it. Everything is simpler here, we take out the glass, disconnect the electric motor connector, use a ten key to unscrew the fasteners and pull out the mechanism itself through a specially provided hole. And so with every door. The casing must be removed before starting work.

The window regulator on the Priora in the Norma configuration is installed in its regular place. Next, you need to connect the rear door buttons, taking into account that each of the buttons has 3 contacts (for power, ground and common wire). The wires from contacts 1 and 3 must be led independently to the control unit under the dashboard. The common wire is connected to one of the wires coming from the controller. After these operations, we connect each Priora lift with an electric motor.

To connect an electric drive to the lift, you first need to remove the power connector from the controller. There are just two empty nests in it. You just need to remove the clamp to easily connect the wires necessary for the operation of the lifts. You also need to run the wires into the corresponding connectors of the rear doors (their colors are red and black). The easiest way to stretch them is along the original wiring of the VAZ Priora. The blog drive2.ru has detailed instructions on this point with photographs. In general, Priora window regulators are quite simple to install and dismantle.

Replacement of the Lada Priora comfort unit. Pinout and repair

The electrical package control unit, or the so-called Priora comfort unit, is a complex electrical device. Its basis is a printed circuit board with numerous microcircuits, relays, control drivers and other elements soldered to it.

The control unit (hereinafter referred to as the product) is installed directly in the car, so its components (microelectronics) are exposed to negative influences. For example: cold, active shaking, temperature changes. As a result, certain elements burn out on the board, the integrity of the contact group is disrupted, which leads to the failure of many vehicle functions important for the daily operation. Unfortunately, in many Lada Priora cars, failure of the electrical package control system has become a fairly common occurrence.

What functions does the block provide?

The main functional purpose of the device is to monitor and control the electrical system in the car. Some important functions for which the block is responsible:

• fog lights, low beam, side lights;
• lighting in the car interior;
• direction indicators;
• power window system;
• operation, adjustment and heating of side mirrors;
• anti-theft system;
• signaling;
• door locking;
• trunk lighting;
• instrument panel lighting.

Partial, and even more so complete failure of the unit causes significant trouble for any car owner. The biggest problems are caused by the failure of the comfort unit in dense city traffic conditions.

Where is the Priora comfort block located?

To gain access to the product, you will need to unscrew the protective plastic walls of the car's center console. They are located on the left side of the front passenger seat and on the right of the gas pedal, on the driver's side. The device itself is located above the control unit. In order to remove the device you will need a 10 mm wrench and a Phillips screwdriver.

Pinout of the Priora comfort block

The main, important elements of the device are:

1. The so-called control drivers. Each driver is responsible for a set of specific functions.
2. Transponder receiver.
3. Relay control.
4. Transceiver. Communicates with the module installed in the door.
5. 2 connectors. The first is responsible for supplying power, the second for transmitting the necessary technical information.

To ensure proper operation of all elements connected to the comfort unit connectors, it is necessary to study the correct pinout (numbered diagram for connecting wires to contacts). The design of the comfort block for the Priora, when studied in detail, is not particularly difficult.

Self-repair of the Priora comfort unit, is this possible?

If you have never encountered soldering, diagnostics of printed circuit boards of varying complexity and configurations, or do not have the necessary diagnostic or soldering equipment, then it is better to address the repair question to qualified specialists.

If you have the above skills and understand the causes of malfunctions, independent repairs are carried out quite often. This is due to the fact that various microcircuits or chips constantly fail.

For example, having established that the reason for the turn signal failure is a failed control driver, it is always possible to purchase a new part and simply re-solder it to replace the faulty one.

Malfunctions and their possible causes

The cost of a new, original unit is quite high, so do not rush to buy a new product, figure out the causes of the malfunctions. Of course, there are always cases when the board cannot be repaired and it is more advisable to simply install a new product to replace the faulty one. Do not forget that the causes of malfunctions can be frayed or broken wires that are connected to energy consumers.

According to statistical data collected on technical support forums, car owners quite often complain about malfunctions in the operation of power windows, turn signals, and parking lights.

If we talk about the components of the printed circuit board itself, the most common breakdowns are associated with: - a break in the W-Line communication line; — burnout of control drivers; — burnout of controllers responsible for correct operation; - the output of their transponder;

— significant oxidation of contacts.

"Important! Before carrying out any electrical work, disconnect the power supply by disconnecting the negative terminal of the battery."

Replacing the lamp

Choice

First of all, let's look at which low beam lamps on the Priora are installed by the manufacturer. So, if you carefully examine the headlight unit of this car, you will notice that it is divided into several compartments. This indicates that the headlight uses bulbs with a single filament, i.e. separately for high beam and separately for low beam.

As for the base, it complies with the H7 standard. There is a wide range of such lamps on the market. Their main difference lies in the principle of operation. So, in addition to the halogen bulbs that are installed on the Priora as standard, you can also find xenon (gas-discharge) and LED bulbs.

It should be noted that the main parameters of lighting elements, including brightness and durability, depend on the operating principle.

H7 standard halogen bulb

Below is a comparison table with the main characteristics of different low beam bulbs:

At first glance, the choice is obvious, and it is not in favor of halogens.

But, you should not make hasty conclusions, since “xenon” and “LEDs”, in addition to their advantages, also have some disadvantages:

• The price of lamps starts from 30 – 40 USD. The cost of halogen lights is on average 10 USD. for a couple. Domestic lamps are even cheaper;
• The luminous flux of xenon and LED bulbs, for example, for fog lights of the VAZ 2110, has poor penetrating ability, so driving with their light in wet weather (snow, rain or fog) is very difficult;

Xenon bulb H7

• Installation of xenon and LED lamps requires the installation of ignition units, and also contains a number of other features. In particular, LED bulbs require the installation of a large reflector and a cooling system. Therefore, it will not be possible to do the installation yourself;
• The lamp ignites gradually, so the low beam turns on with some delay.

For these reasons, the low beam lamp for the Lada Priora is selected individually, depending on the financial capabilities of the car owner, the region and the weather in which the car is most often planned to be used. However, it should be noted that halogen lighting elements are still the most popular.

Removing the casing

How to replace a light bulb

As mentioned above, xenon and LED bulbs must be installed by specialists. Therefore, below we will consider how to change the low beam lamp on a halogen Priora.

So, the work is done in this order:

• First of all, you need to open the hood and disconnect one terminal from the battery;
• Next, from the back side of the headlight unit, you need to remove the rubber casing covering the low beam compartment, which is located closer to the car’s fender;
• Then you need to disconnect the connector with the machine wires from the contacts;
• After this, you need to unclench the ends of the latch with your hands and move them away from the hooks. Then the latch should be moved away from the base;

In the photo there is a spring clamp

• Now that the base is not fixed in anything, you can remove the socket from the headlamp, and then remove the lamp from the socket;
• Then a new lamp is inserted into the socket. This operation should be performed carefully, without touching the glass flask with your fingers. Grease stains remaining on the glass can lead to overheating of the lighting element and its premature failure;

Base with light bulb

• Next, the structure is assembled in the reverse order - the socket with the lamp is inserted into the headlight unit and fixed with a spring, after which the block is connected to the contacts. Next you need to reinstall the rubber casing;
• To complete the work, you need to connect the terminal to the battery and check the operation of the low beam. In this case, the ignition must be turned off.

Here, in fact, are all the instructions for replacing a light bulb on a Lada Priora. The work is performed the same way on both the right and left sides.
