How to independently replace the electrical package controller on a Lada Priora?

With the online store DiscounterAvtoAzbuka, repair costs will be minimal.

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.

About the repair of the comfort unit

This is a very tricky issue. It’s worth clarifying right away that an ordinary car enthusiast has no business even trying to do this. For such an operation, you need to have at least a professional kit for soldering microcircuits on hand. Or better yet, a soldering station. No service station will undertake this work. So it’s easier to replace the failed unit with a new one.

In the video below, a specialist checks the serviceability of the Priora comfort unit.

lekha=60, I don't know. I'm having a hard time finding my way around here. Now I tried, the right mirror to the right and down is still not working. What to do ?

Added after 1 hour 32 minutes Can anyone help me figure it out?

Can anyone help me figure it out? To diagnose the EP controller, there are no psychics on the forum who can identify errors in your ECP through a monitor.

The learning key does not fit into it. Pull the chip out of the old learning key and insert it into the learning key of the new lock.

Maybe there is a link on how to teach when changing the comfort unit? Just as always teach https://www.priorovod.ru/showthread.php?t=22169

Gyzmi58, So do I need to change my key with buttons to a new one? It seems like he can be trained once?

Added after 2 minutes Gyzmi58, So do I need to change my key with buttons to a new one? It seems like he can be trained once?

Thank you very much for your attention to me. Please;)

If I connect it there and just check the locks and mirrors and then put my old BC back, the engine will start. You can only connect the connectors and check everything, you don’t have to remove the unit. Although it is not difficult to remove it. The engine will start with its block.

Gyzmi58, In general, I went to pick up the block and dropped it off on the spot. Nothing changed. I came home and decided that I would go for diagnostics, but... weekend I decided to dig deeper and for good reason. When opening the rear right door, everything started to work; when closing it stopped, everything was clear. It turns out that the door actuator wire got under the limiter loop inside the door and got jammed there. That's why there was whistling at that door. I fixed everything, reconnected the wire, reassembled everything and it works. Thanks everyone for the advice.

Added after 1 minute Look for the shorty by whistling from the BC and probably from the place where the short was lost.

I came home and decided that I would go for diagnostics, but... weekend I decided to dig deeper and for good reason. Well done for figuring it out yourself: good::good: It’s much more difficult to understand in virtual reality..

pinout, electrical package control controller and circuit

Almost all modern cars today are equipped with electric windows, which allow you to control the opening of the windows at the touch of a button. And the Russian Priors in this case are no exception. The control device, with the help of which the windows are raised and lowered, as well as many other functions, is called the Priora comfort unit. You can learn more about its structure, as well as repair, from this article.

Description of the electrical package control unit

The electrical package controller in Priora is a device used to control the functionality of the vehicle. This unit is responsible for the operation of turn signals, power windows, control panel lighting, dimensions, fog lights, interior lighting, and rear window heating system. This device also ensures the normal operation of the reversing lights. The fact that the car is equipped with this device makes it even more practical.

Location

The control device on the Priora is located above the electronic engine control unit, at the bottom of the center console, in the middle. In this case, the device is connected using two connectors - power and information. The power output is used to supply voltage to the control unit, and the information output is used to perform the functions of the device. It should also be noted that the control unit is protected from external influences of dirt and moisture.

In general, this device is a circuit installed in a plastic case. The board itself includes 15 chips, each of them performing certain functions. This is the entire electrical part of the car, including power windows, door open sensors and a control system for external electric mirrors (the author of the video is the CompsMaster channel).

terms of Use

In order for the node to operate normally, certain conditions must be met:

• the air temperature level in the car interior should be from -45 to +40 degrees;
• the air humidity level in the cabin should be no more than 90%;
• The voltage parameter for normal operation should vary around 9-15 volts;
• The atmospheric pressure level should be up to 800 mm Hg.

As practice shows, malfunctions in the operation of this device often appear as a result of its overheating or disconnection of wires or contacts inside the structure. If you are faced with the problem of a device failure, first of all you need to visually diagnose it. It is quite possible that the reason can be discovered only by looking at the device.

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.

Video “Diagnostics of the electrical package control controller”

How to diagnose the functionality of the electrical package controller in a garage environment - see the video below (the author of the video is Vyacheslav Kravchenko).

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.

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.

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.

Electrical package control unit in Priora

The car electrical package controller is a unit responsible for the functionality of the car.

The node regulates the operation:

• electric window lifts;
• main panel backlight;
• functioning of turn signals;
• side and fog lights;
• rear lights;
• heated rear view window.

All these devices must work clearly and harmoniously. Since the safety of the driver and passengers during the trip largely depends on them.

Also, the control unit for the Priora electrical package adds additional convenience to the driver in driving the vehicle. Hence its running name “comfort block”.

Electrical package control unit: vehicle electrical equipment is under control

March 8, 2018

In modern cars, all electrical equipment is combined into a single system called an electrical package. The control of the electrical package is entrusted to special electronic units - read all about these devices, their design and functionality, as well as the correct selection and replacement in the article.

What is an electrical package control unit?

Electrical package control unit (electrical package controller, comfort unit, central body electronics unit) - a component of the vehicle’s electrical system; an electronic device based on microprocessors/microcontrollers that acts as a central control unit for auxiliary systems and electronic components of the vehicle in order to increase its comfort and safety.

In modern cars and many trucks, various electrical equipment - power windows, external and internal lighting and light alarms, door locks, rear-view mirror drives and others - are assembled into a single system called an electrical package (EP). The functions of monitoring and control of the electric drive are assigned to the central control unit (controller). The use of an electrical package control unit allows you to implement various control schemes for automotive electrical equipment:

• Manual control via appropriate switches on the dashboard, doors, steering column switch, etc.;
• Remote control of electrical equipment using a car alarm or telematics system;
• Automatic control of certain elements in accordance with the state of the vehicle, engine controller and on-board computer;
• Automatic control of the main elements that ensure the safety of the car (central locking, windows, lights) when the status of the car alarm and/or immobilizer changes.

Thus, the electrical package control unit allows you to increase the comfort and safety of the car, as well as expand the functionality of its electrical system by using the advantages and capabilities of the CAN, LIN, K-Line and other data transmission protocols.

A malfunction of the electric drive controller can completely disrupt the functioning of the vehicle's electrical equipment, so this unit must be replaced as soon as possible. To make the right purchase of a new unit, you need to understand the existing types of these devices, their features and functionality.

Internal structure of the electrical package control unit

All modern electronic controllers are built on the basis of microprocessors or microcontrollers, which take on the functions of controlling electrical equipment circuits. The processors contain algorithms for controlling equipment in various situations - during manual control, in automatic mode, etc. Direct control of the equipment is carried out using small-sized electromagnetic relays or electronic switches based on powerful field-effect transistors.

Electronic components are located on a printed circuit board, which is installed in a plastic case; connection to electrical equipment is made using standard electrical connectors. One to three connectors can be installed on one block; often the power and control circuits are separated, and separate connectors are used to connect to them.

The electrical package control unit is located under the dashboard or under the center console; it is usually installed near the relay and fuse mounting block - this reduces the length of cables between these units. The unit is mounted with screws or using a metal bracket.

Types and functionality of electrical package control units

Electrical package control units used in various vehicles may differ in functionality and operating features, but in general they are responsible for controlling the following electrical equipment:

• Windows on all doors and window locking mechanism;
• Drive of external (side) rear-view mirrors;
• Heated exterior mirrors;
• Heated rear window;
• Heated front seats;
• Central locking;
• Locking mechanism and locks of the trunk and hood;
• Front and rear direction indicators;
• Interior lighting - lamp on the ceiling, lamps on the central pillars, lamps on the thresholds, luggage compartment lighting;
• Dashboard lighting;
• Exterior lighting devices - fog lights and rear fog lights, side lights, reversing lights.

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.

Comfort block functionality

The main functions that the comfort unit contains are electrical control in the car. Since the list of tasks performed is extensive. Malfunctions in the operation of the unit can seriously harm the driver, especially during dense traffic around the city.

Comfort block tasks:

• turn signal indication;
• car interior light;
• fog lamps, low beam lights, parking lights;
• electric double glazing unit;
• side mirrors operation, adjustment, heating;
• anti-theft mechanism;
• door blocking;
• security alarm;

How to repair the electrical package control unit on a Lada Priora

"Lada Priora" drives around the city. Here is the crossroads. Required traffic light signal. And the planned turn takes place. The driver's hand habitually pressed the steering column switch. But the warning light is not blinking. From all sides there are indignant beeps and screams. Turned without signaling! The driver embarrassedly presses the hazard warning button to stop and investigate. However, there is no response here either. Yeah! It's probably the turn signal relay! It needs to be changed, that's all! Fortunately, auto parts stores are everywhere now. But here, too, not everything is so simple. It seems that the “electrical package” or, as it is also called, the Priora comfort unit, has failed.

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.

Attention! This must be done during any work related to the electrical equipment of the car. And especially those that are controlled by a computer

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.

Important! The knot comes out only in one position, and if you couldn’t pull it out right away, don’t panic. Just turn it gradually to remove

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.

About the repair of the comfort unit

This is a very tricky issue. It’s worth clarifying right away that an ordinary car enthusiast has no business even trying to do this. For such an operation, you need to have at least a professional kit for soldering microcircuits on hand. Or better yet, a soldering station. No service station will undertake this work. So it’s easier to replace the failed unit with a new one.

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.
