Features of connecting the signaling system to the central locking system (Lada Granta)

The simplest reasons

Why doesn't the central locking open or close the doors? To answer this question, sometimes it is enough to look at the fuse box. The central locking system is dynamic. Various short circuits and other similar violations are not uncommon. Therefore, fuses blow quite often. Don't forget to check the condition of the alarm unit. On some models, fuses are also provided there. If at least one of them is faulty, the central locking will not work. Sometimes you may encounter such a situation.

So you go out in the morning, press the door open button, and nothing happens. Most likely you forgot to turn on electrical appliances in the car. This led to the battery being completely discharged. To verify this, open the car with the key. And turn on the ignition. It probably won’t turn on, or will go out immediately when you try to start the engine. All that remains is to charge the battery. If the engine does start, then you should look further for the reason.

The next step is to check all the chips and connections related to the signaling and central locking. Even a small contact movement can lead to this system failure. Don't forget that one of the chips is located in the door. Therefore, you will have to remove the door trim. Just before doing this, check the condition of the wire going to the door motor. The tourniquet is usually placed in the area of ​​the lower loop. Wires often break, especially in winter. In this case, again, the central locking will not work.

Useful tips

In order for the door to open if there is a problem with the key fob, you must complete the emergency deactivation procedure. It involves introducing a special code value, but is sometimes performed without it. It all depends on the alarm model.

Interested in how to open a Starline car alarm without a key fob, the user needs to perform the following steps:

1. Open the door mechanically.
2. Activate the ignition circuit and leave it on for 20 seconds.
3. Press the “Jack” mode activation key three times.
4. Turn off the ignition. If these steps are performed correctly, the security mode will be deactivated.

You can also use this method:

1. Open the car door, start the engine and ignition.
2. Enter the first digit of the password using the “Valet” button.
3. Turn off and turn on the ignition again.
4. Carry out the second action with the remaining numbers.

Having dealt with the reasons for the key fob not working, all that remains is to find the best way to eliminate them.

Electronics

In addition to the reasons described above, the problem may lie in small electronics. The check should begin with the key fob. First of all, the battery and the condition of the buttons are checked. Perhaps they stick and do not work at the right time. If the board itself is faulty, the key fob simply will not respond to external stimuli. The LED on its body will not light up. It's good if you have a spare key fob. Otherwise, you will have to change the alarm, or find exactly the same key fob.

Next, the alarm control unit is checked. The verification method is usually indicated in the instructions. Lastly, they check the microboard located on the central locking drive motor. At the same time, they look at the condition of the drive itself. All failed parts are replaced. The most difficult thing is with the control unit. It is practically beyond repair. Therefore, it is much easier to install a new alarm. Sometimes the key fob loses synchronization with the unit, then it will have to be reprogrammed.

Solve the problem of central locking on the new Lada Grant FL

From the very beginning of sales of the new Lada Granta family, owners began to experience inconvenience when using the central locking (CL). The fact is that in some car versions, when the engine is running, the central lock only closes the driver's door. Closing all doors is only possible when the ignition is turned off. This algorithm for the operation of the central lock complicates life for owners when installing an additional car alarm with auto start.

Here's what Lada Granta FL owners write in one of the VK groups:

The new FL grant has a strange locking mechanism. 1. if you lower the driver's flag when the car is turned off, then all the others will lower and close, everything is fine. 2. If the engine is running, then when the driver's flag is lowered, the rest remain open. Well, God bless him, maybe the thieves won’t get caught in the traffic jam. BUT! When you arm the car with a manual transmission and get out of the car, the engine naturally runs before arming...you arm it and...since the engine is running, one driver's flag goes down. Three passenger doors remain open. Pressing the close button again does nothing. You have to disarm and re-arm, and this already resets the autorun. Indeed, such an algorithm for the operation of the central locking is indicated in the car’s operating manual:

Central locking and unlocking of side doors from the passenger compartment (in a variant). To lock the side door locks from inside the vehicle, press the lock button into the driver's door or (in the optional version) press the lock button in the driver's door module. In versions with a driver's door module, locking the side doors using the button in the driver's door is only possible when the ignition is turned off. At the moment, this information has already been conveyed to AvtoVAZ. It remains to be hoped that this feature of the central locking system will be corrected in the near future.

Mechanical problems

In addition to purely electronic causes of malfunction, central locking failure can be caused by simple mechanical failures. Sometimes you can see how all the doors except one open from the central lock. The reason is the cylinder drive rod. For a more clear description of the method of troubleshooting, we first consider the structure and operating principle of the lock.

From the remote control, the signal goes to the control unit, and then it goes to the motor located in the doors. It sets in motion a rod, one end attached to the larva. Depending on the specific signal, the bar rotates the cylinder, opening or closing the door. Sometimes the rod end falls out of the mount. In this case, a failure of the central lock on one of the doors is observed.

Correct seat belt adjustment

The seat belt must pass through the center of the shoulder, no matter how tall the person is. Few people know that the position of the mount on the B-pillar can be changed in the vertical direction. To do this, just press the latch and move the loop.

There are two options for connecting this option: 1) Lever in “D” – the doors are locked, lever in “P” – the doors are unlocked
2) When you start moving and pick up speed up to 20 km/h, the doors are locked, lever in “P” the doors are unlocked
I’m telling you : Today I was visiting Dima Hedgehog. Clicked this option.

According to 1 option

I like it. Additionally, I can say this (I experimented) - when you stop (the lever is in D) and open the driver's door (button), when you start driving at 20 km/h, it is automatically blocked again. If you stopped and opened any passenger door (or several) and then drove off, the doors are not blocked, but if you open the driver’s door, then all are blocked.

you will object, they say, you parked and manually pressed the lock. What is the point of automation then? As soon as I started up in the parking lot, it locked. and until I arrive at the office, even at a traffic light, anywhere, it’s always locked... and there are no unnecessary twitches of the lock drive.

Types of faults

The central locking system installed on cars has the same operating principle and a similar connection diagram. Before starting repairs, you should find out how to disable the central locking and diagnose the equipment.

If the car has an alarm system, the central locking is controlled using a remote control - a key fob. When you press the keys, a signal is sent to the control unit and functions are adjusted. The activated central locking system opens the doors.

The central locking system includes switches, connecting wires and electric or vacuum type drives as common elements. Actuators are activators. The front doors have a central drive, which, when activated, sends electrical signals to close or open the remaining doors.

Auto central locking activator

general information

On machines equipped with Norma, central locking control units are installed, which are replaced with new ones if they break down. On Luxe vehicles, TsBKE are used instead. Below we will try to take a more detailed look at the central locking unit and its control unit, their relationship with the remote control, symptoms of a malfunction of this part, and also provide instructions for replacing it yourself.

Now let's look in more detail at remote control, which is intended not only for locking and unlocking car doors at a distance with synchronous activation of the security mode. In addition, it allows you to lock all locks with one turn of the key, lock and unlock all door locks by pressing one button located inside the cabin, and also turn on and off the car alarm both remotely and with the key.

Operating modes

Door locks on Grants are blocked by pressing the corresponding key on the remote control, after which they can be unlocked using the remote control in stepwise and simultaneous unlocking modes. The first of the listed modes will allow you to unlock all door locks by double pressing the key (first the driver's door is unlocked, and then all other doors). When you activate the second mode, you can unlock all the doors of the car at the same time, with one click.

To change the mode, the car owner will need to perform the following steps:

• first you need to turn on the ignition with the remote control key;
• then you will need to press and hold the unlock and lock keys in this position for five seconds;
• After the buzzer sounds, release the keys.

Blocking

If, after unlocking the door locks, you do not open the trunk or one of the doors, or do not turn on the ignition, then after twenty-five seconds all doors will be locked again.

Control from the cabin

When blocking doors directly from inside the car, you need to press the corresponding button located on the driver's door, or press a similar button in the module of the same door. Unlocking will require lifting the desired key on the door or pressing it in the module. To lock the doors from the outside, you will need to turn the key in the lock located on the driver's door clockwise, and to unlock the doors, turn the key in the opposite direction.

Window control

By pressing and then holding the lock button in this position for three seconds, you can raise the lowered door windows, with the front windows going up first, followed by the rear door windows. By pressing and holding the unlock key for three or more seconds, you can lower the raised windows in a similar sequence.

Opening the trunk

Unlocking the trunk lid lock on a Grant using the remote control is possible only after turning off the ignition. So, when opening the lid, you must either press the key on the remote control twice, with a minimum interval, or press it once, but hold it down for at least several moments. When the security mode is activated, the trunk will open synchronously with the security zone being turned off for at least half a minute. To close the lid you will need to slam it shut again.

Causes of malfunctions

If the central locking stops working, you must first check the fuse box. Short circuits and various disturbances often occur in the central locking system, which leads to blown fuses.

Checking system fuses

The central lock does not operate when the battery is completely discharged. To check, you need to open the central locking with the key and try to start the car. If it does not start, then the reason is the battery is discharged.

The reason why the central locking system does not work may be due to a breakdown of the electronics. You can open the car without a key using the key fob. If the central locking does not open with the key fob, you should check the batteries and buttons of the key fob. They may stick and not work at the right time.

At the next stage, using the instructions, you should check the alarm control unit. It is possible that due to problems with it, the central locking works, but does not close all the doors. The last thing to check is the microboard, which is located on the activator motor, and at the same time the drive itself should be checked. Defective parts must be replaced.

Electrical circuit diagram for central locking

If the central locking does not work, this may be due to mechanical problems: the cylinder drive hose is faulty. The signal received by the control unit from the key fob is transmitted to the motor on the doors, which should operate and act on the hose fixed in the cylinder. If one end of the hose falls out of the cylinder, the drive is turned off. In this case, the door will not be able to open or close. Thus, the reasons why the lock does not work or malfunctions can be either electrical or mechanical.

General recommendations

Incorrect operation of closing/opening doors makes up the bulk of problems with car alarms. Moreover, if on cars with the simplest configurations this is expected, since you have to assemble the central locking from scratch and configure all the drives (often of questionable quality), then on modern cars with a CAN bus the installer is not immune from problems arising in the future. Knowing the typical problems that arise with the central locking, the car owner can fix everything himself.

Repair of partial failures of the vacuum central locking system

In many cases, central locking malfunctions are accompanied by prolonged pump operation. It does not stop working until the protection turns it off.

1. The central locking system opens and closes the doors until the compressor turns off. In this situation, the cause is a faulty drive switch. Voltage is supplied to the pump board from the activator; when it is supplied to plus, the doors open or close. The switch needs to be repaired or replaced with a new one.
2. The doors close and open, the central lock does not open only some of them, while the compressor continues to work until the protection is triggered.

Vacuum pump central lock

There may be several reasons for malfunctions:

• the tightness of the vacuum line hoses is broken;
• signals are sent to the compressor control board, but it does not respond to them;
• there is no signal from the limit switch of the drive of one of the doors to the pump control board, so despite the fact that the doors have opened or closed, the compressor continues to work.

Collection of “people's councils”

If the central locking is not working properly, but you know that the key fobs are fully functional, you can try the following steps:

1. The power supply circuit of the central locking controller is protected by fuse F22. This element can be replaced or simply disabled and then installed back;
2. Let's say no current flows to the actuator of one door. Then find the terminal block by opening the door 90 degrees. In order for the broken contact to be restored, sometimes it is enough to disconnect the mating connector and connect it again;
3. Even if the key fob is working, check whether the self-tapping screw is screwed in all the way. It is recommended to loosen the fastening a little, and then everything works reliably.

To follow “tip number 1”, look for the fifth fuse from the top in the mounting block. The rating of this element is 15 Amperes.

Greetings! I decided to add an entry about connecting the alarm system to the standard central lock of Kalina 2, Grants or Priora. Using the example of the good old Starline A91, without any modules and adapters)) While installing the A91 on my father’s viburnum, a difficulty arose with connecting to the central locking system. But for some reason there is very little information about this on the internet. So, to connect to the central locking system, you need to remove the driver’s door card. Here you need a bundle of wires from the activator. According to the diagram below, 2 and 7 are the power, the motor winding. A 1 and 4 signal from the position sensor. We will need a brown wire.

Now let's look at a typical connection diagram for Starline A91

There are blue and blue-black unlocking signals, and green green-black locking signals. Now, in order for the doors to close, you need to break the brown wire. To open, you need to connect it and apply minus. Therefore, the wires and connector X2 need to be connected as follows

We plant black and red on MASS. We program the simultaneous opening of doors. To do this, press the Open and Close buttons on the standard remote control and turn on the ignition until the signal (about 5 seconds) That's all. Now with this connection, all standard buttons will work. No extras There is no need to install the activator. It is also not correct to connect to wires 2 and 7. In this case, the central locking button on the SUEP will not work. The only problem here is that you will have to pull 2 ​​wires into the door.

Now about the tire falling asleep when the doors open only after the second press of the open button on the key fob. This occurs after approximately 10 minutes of bus inactivity. In order for the doors to open after the first press, a double pulse must be given. To do this, in the programmable functions of Starline A91, select Function No. 1 option 3

On Lada Granta and Kalina cars in the Norma trim level, a central locking control unit is used (on the Luxe trim level, the central locking control unit is used instead). If it malfunctions, it is replaced with a new one. This article tells you where the central locking unit is located, what it is responsible for and how to change it yourself.

Repair of electric central locking

Over time, central locking solenoids do not tolerate low temperatures well due to high humidity, especially in spring and autumn. First they begin to jam, and then the door no longer closes or opens. The solenoids can be cleaned and lubricated, but it is better to replace them with motorized drives.

Electric central locking drive

Activators may not work or work partially on one of several doors for the following reasons:

1. Damage to the circuit or poor-quality contacts in the electrical wiring.
2. Relay is faulty.
3. If control is carried out from the board, then it is possible that the reason is its malfunction.
4. Poor contact at device terminals or damage to the drive electrical circuit.
5. Wear of activator components.
6. The winding has burned out.

Repairing a car's central locking system should begin by checking the non-working activators to see if they are receiving voltage. If the door lock function is activated, there should be voltage on one wire. If a signal to open is received, voltage leaves the 1st wire and appears on the 2nd. Based on the results obtained, further actions are performed: either the activator is checked and repaired in case of a malfunction, or the entire circuit is checked, correcting damaged areas. Broken wires most often occur in corrugated areas.

Sorry, there are no surveys available at this time.

Abnormal opening/closing of doors

In some cases, the alarm is triggered when the door is closed. In this case, the key fob may display information that the door is open. When you close it again and press the corresponding button on the key fob, the car immediately opens and the alarm goes off.

The problem is caused not so much by the system itself, but by the adjustment of the driver's door actuator. It cannot reach the standard traction, and the limit switch does not allow the central locking to open the doors. In this case, there are 2 options:

• Remove the driver's side door trim and adjust the actuator on the rod.
• Replace the two-wire activator with a similar system, but consisting of five wires. After this, you need to give him control of the central locking from the standard key fob. It is worth noting that this method is the most effective.
• After the car has been idle for a long time and the security system has been disarmed, a problem may arise when the doors automatically close immediately. The problem is solved after pressing the open button a second time.

In addition, the wiring insulation may be damaged and the fuse on the green and blue wires in the central locking connector may have burned out. The presence of a short to ground contributes to the spontaneous opening and closing of doors. The problem may also lie in the equipment being in service mode. In this case, the shock sensor will not work. In this case, the key fob will notify you of a malfunction with a signal displaying a wrench. This icon is selected by button 3 and disabled by button 2.

Almost every car has a modern alarm system. It protects it from unauthorized access and also allows you to perform some actions remotely. But during operation, drivers repeatedly encounter problems when the car does not open using the alarm key fob.

Possible difficulties and ways to eliminate them

You can, of course, purchase Lada door closers and door stops and create repairs in accordance with the instructions. But this operation can be performed using the most productive method. To carry it out you need:

• rubber tubes;
• screwdriver;
• Silicone Grease.

Frequent symptom (one, separate sign of the disease)

If the lock breaks down, there will be a loud sound before the door opens/closes. The front door lock system is manufactured in such a way that the alloy may rattle from time to time. In order to remove this problem, you need to pull out the lock itself and put rubber tubes of a suitable size on the levers. Immediately all the sounds coming from ahead will disappear. When closing the doors, only a bang will be heard, and all sharp and loud sounds will fade into the past.

If the car has an all-purpose body, then you should also adjust the lock on the trunk door. The locking tongue itself fits into the bracket. You need to find it and check the tightening of the screws. Later, the lock needs to be lubricated with silicone grease, after which the door must be checked by opening it. If the lock does not work well, you need to screw in the rubber stops, but they should not be over-tightened. Later, check the drive rod of the Lada Granta door lock.

If jamming and play are observed, they should be removed. At the same time, all this needs to be created immediately. You can also purchase limiters for the trunk lock. Before purchasing Lada door closers or door stops, you should first consult with a specialist. Having received the necessary and important information, you can select the highest quality limiters. Problems with the operation of the lock can be solved by making good quality adjustments. To do this, certain actions must be carried out.

You should pay attention to the gap between the drain and the top edge of the door. A good gap size is considered to be a hole into which a plastic card can fit. In this position, aerodynamic sounds and the tightness of contact with the drain will be in equilibrium.

Most often, the reason for poor operation of locks is the difference in the radii of curvature of the upper door frame. If you look at it in detail, you can see that when simultaneously adjusting the locks at the back of the machine, they constantly touch the upper part of the sealing rubber unequally. Tight opening compresses it much more strongly in the closed position. To adjust the locks, you can use the following method.

Refinement of the castle

The method is used by experienced drivers who prefer to fix any malfunction without the help of others. This is a makeshift option, but it helps to adjust the smooth running for a year and a half and get a tight fit.

1. At the end, insert a limiter into the lock; you can use a thick plastic tube. This is done so that the element does not snap into place and the tab that needs to be modified does not “disappear.”
2. Using Ratfil, sharpen the lock tongue, which engages when closing with a response bracket.

If you grind off a huge sheet of alloy, the door may not close later.

Craftsmen advise systematically inspecting the seals and the external position of the hinges; in this case, adjusting the doors on Grant will need to be done less than once a year.
