Where is the central locking control unit? Installation, possible malfunctions

Most modern cars, including AvtoVAZ products, are equipped with a central lock. The main function of this system is to prevent attempts to unauthorized access to the cabin and hijacking the car. Completion of the central lock is an electronic unit, actuators or actuators, limit switches, key chain for controlling the operation of the Central Station. Like any equipment, the central locks fail.

During the repair, car owners may have difficulties. Not everyone knows where the central lock control unit is located. But it is often the cause of all faults in it.

Features of the device

Central locking is a complex of equipment that, when certain commands are received, opens or closes the car. For greater ease of operation, the command flow is performed remotely (remotely). Some car owners choose for themselves a convenient function of locking all doors at a certain time. Why is it necessary? This function is very useful when the driver did not have time, or even forgot to close the door. But if you lose the keys and there is no second console, then this is a serious problem. In road traffic accidents, the security system automatically opens all locks.

Device

The central locking circuit is a set of sensors, limit switches, actuators, control unit.

Limit switches are required to obtain information about the position of the door. This data is transferred to the control unit. Due to the switches, the lock part is fixed. The car doors are equipped with a special cam mechanism. To enable it to be fixed, there are special miniature switches in the front doors. Each actuator has two switches. One switch is responsible for locking the locks, and the second one for opening. The circuit also provides two additional actuators. In the lock actuator, one more switch is installed on the lever device. He determines if the door is open. If this is the case, the switch contacts are closed. The CB is deactivated.

The central lock control unit VAZ-2110 receives signals from the miniature switches and then commands the control mechanisms. To open the locks, the signal is applied to the actuators.

Setting the TZ

The central lock in the car (and in particular cars from "AvtoVAZ") is an additional option. However, this is relevant for the 2000s. Now all AvtoVAZ products are equipped with a central lock mechanism in all trim levels. On those cars where the CP is not installed, the owner can install the device himself. The installation of a central lock is not a complicated procedure.

The first thing to do is to disconnect the battery terminals. Also remove the door cards and the mechanism of the power windows. After that it is necessary to choose a suitable place for the installation of activators. The mechanism can be installed in any position. But it is important that the thrust of the actuator can move freely. Cars VAZ-2110 have a special design of doors. The thrust before installation must be bent in a certain way. This angle should be both minimal and clear. If it is close to the arc, or the distance from the thrust to the clamp is too large, problems may arise in the system operation. There will be a shortage of power to effect traction. All effort will go to overcome the bend.

Features of the laying of wires

After the activator is installed, the wires are routed from each door of the car to the place where the central locking control unit is located. On the "tens", as well as on many other cars, it is better to lay the wires on the lower part of the doors. So they will not be affected by window lifters and other moving components. In places where the wires are connected, they are well insulated. Otherwise, short circuits are possible. For laying wires between the car body and the doors, rubber corrugated parts are used. After the wires are stretched, make sure that they are not broken during the operation of the door.

Mounting of the control unit

The installation of the central lock also provides for the installation of a control unit. Most often it is put either in the doorway or behind the central panel. It should be borne in mind that the safety of the car depends on the location of the unit. Control systems are installed in hard-to-reach places for hijackers.

From where the control unit of the central lock is located, will depend not only on the safety of the car in terms of hijackings, but also on the operability of the system itself. It is not recommended to install the control electronics at the bottom of the doors. There, dirt and water accumulate. After a while this can lead to the device failure. Also, when installing the unit, it is recommended to pay attention to the window regulators. The unit must not interfere with their operation.

Connectivity

Then connect the system. For this purpose, there is a central locking circuit. The battery is connected to the battery via a fuse. After connecting all the wires, check how the equipment works. In the testing process, attention should be paid to the smoothness and ease of operation of the mechanism. If the solenoid produces insufficient force to move the thrust, then check the location of the actuator once again .

The central lock with alarm can work in a complex. Modern alarms have the possibility of connecting to them a central lock. But here it is necessary to pay attention to the compatibility of electrical circuits.

Typical malfunctions

These devices also fail. There are a lot of reasons for this. To identify a breakdown, it is necessary to carry out a diagnosis. There are mechanical and electrical breakdowns. Consider these faults and learn how to eliminate them. Although sometimes repair activator is economically unprofitable - it is cheaper simply to buy a new central lock. The price of the activator is 200 rubles.

Mechanical faults

This includes various mechanical damages, weakening of fasteners of rods. The end switches may be loose. This involves the violation of regulation information, the destruction or even wear of parts in the gearbox of the actuator. To mechanical carry breakages, the reason of which is connected with poor-quality installation and adjustment. If such problems are observed, it is necessary to eliminate them as soon as possible and to remove the reasons. But it's easier to replace the central lock. The price for executive devices starts from two hundred rubles.

Electrical breakdowns

These problems include all the breakdowns that can occur in the electrical circuit. Before you start the diagnostics, you should check that the electrical network in the car is completely in working order, there are charged batteries in the key fob, and the fuses in the central locking module are not blown. Often, it was possible to restore the operation of the faulty central lock only by replacing the fuses. If the CPU still does not work, you should look for a breakdown in the console or in the mechanism itself.

If the remote control fails, then the code is overwritten in the electronic key. If the problem can not be solved in this way, the transmitter in the key may be faulty. In these cases, experts recommend having a different key with the code. If you lose the keys, you will have to buy new ones.

Also, the fault can be connected to the remote control receiver. The easiest way to determine a fault is by installing a known good receiver. If this is not possible, then the door cards are dismantled. After checking the mechanical part, check whether the energy is flowing to the control terminals of the actuators. Probably, wires were cut or broken. The absence of power at the terminals is also associated with the oxidation of the wires. The control unit may fail due to various malfunctions in the alarm management system. The replacement of the unit will help here. It is enough to know where the central lock control unit is located. Often it is behind the radio, on the driver's side. Then you need to disconnect it and install a new one instead.

Conclusion

So, we found out what the central lock in the car is. As you can see, this is a very useful device, which greatly facilitates the process of locking the doors. Feedback from those who already use such a device, only positive, which indicates its convenience.
