The alarm is very useful and multifunctional. With its help, you can protect your car from thieves or accidental collisions in the parking lot. More complex security systems are capable of using a key fob to open the trunk from a distance, start the engine, or perform a host of other interesting functions.
Lada Granta models such as Norma and Standard do not have an anti-theft system in their factory equipment. The factory simply does not install them, since the designers considered this part superfluous, if you do not take the immobilizer into account.
That is why this article was created, since the relevance of the issue of installing an alarm system on the Lada Granta is soaring at exorbitant heights. Despite the fact that there is a huge range of security systems for cars on the market, they have almost identical installation schemes, with only minor differences.
How to replace the central locking unit
You will need: remove the mounting block (put it aside without disconnecting the connectors with wires), a new central locking control unit (art. 21900651201000, price about 1100 rubles).
- Unscrew the two screws that secure the block.
- Disconnect the connector with wires (pull it towards you).
The most difficult thing is to unscrew the mounting block mounting screw, unscrew the central locking block mounting bolts, remove the connector from the central locking block and install it in place. If it is not possible to tighten the central locking bolts in reverse order, use plastic ties.
The video also shows the process of removing and installing the central locking control unit on the Lada Granta:
By the way, did you know that LADA cars can be equipped with sensors? This review will change the way you think about block management.
Here we will look only at the diagram for connecting the alarm to the central locking and talk about the various subsidy configurations. The first option is for "luxury concessions", those in the cabin where there is a central locking control button. If there is no such button on the armrest, as perhaps the armrest itself, then another design option will suit you. Now let's look at all this in more detail.
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.
Preparing the car before connecting
What does the central lock control? A special lock to which the lock drive wires fit. Two wires are connected to it to the driver's door microphone. More precisely, this wire is used separately in Grant, it has a brown sheath and the second contact of Mikrika is connected to ground.
The “micric” itself is located inside the actuator. So, the first tip: after removing the left front door trim, you need to find the cable going from the actuator to the 7-pin connector.
Depending on the equipment, you will see the following under the skin:
- 6 wires are suitable for the connector (from 2 mics and one block);
- The drive wires (pins "2/7") are not connected, but the brown wire is still connected to pin "1";
- The only wires left are those that need to be connected to contacts “4/6” according to the diagram.
Connecting the signal means that the wires of contacts “2/7” are in any case connected to the central locking control unit. The cables from the three drives are always connected to the standard device. It is necessary to connect a fourth one if the factory does not do this. It may be necessary to lay a two-core cable from the door to the control unit:
The central locking control unit is located under the fuse box and is designated BUBD-2190.
Here's how one car owner coped with the task:
The cables coming out of the door are connected to the wires of the standard terminal block. The connector pins used are “3” and “4”. The main thing is not to confuse them. Take another look at the diagram to see exactly what we're talking about.
Installation
Installing an alarm system on a Lada Granta with your own hands consists of several stages:
- Removing the plastic steering column lining. Then the instrument panel is removed and the map mounted on the driver's door is removed. The parts are secured with screws and plastic plugs, which are removed with a special mounting spatula.
- The installation location of the main unit depends on the dimensions and characteristics of the product. Small modules of Starline or Pandora products are located behind the dashboard.
- Route the control diode to the front pillar trim on the driver's side. The antenna unit (in some assemblies contains an impact detection sensor) is glued to the top edge of the windshield. If the owner has previously installed the unit in a different location on the glass, it is recommended to replace the layer of double-sided tape that was glued to the module body at the factory.
- The siren sound signal is installed in the engine compartment, the cable is routed into the passenger compartment through standard channels received in the engine panel. Since overheating of the housing damages the electronics of the unit, the exhaust manifold provides protection from the sound signal. The base of the siren is fixed with screws that are screwed into pre-drilled holes.
- When installing an autostart alarm, it is necessary to install a sensor that measures the temperature of the cylinder block. The device is fixed with a nut according to the manufacturer’s recommendations; do not squeeze the element when installing.
Installation Rules
An alarm installation map (separate for each device model) is included with the factory installation instructions. During installation work, the elements are securely fastened with self-tapping screws or plastic clamps. When using double-sided tape, the adhesive layer may be destroyed due to temperature changes, loose parts may be damaged, and the vehicle's standard electrical wiring may also be destroyed.
