Solving problems with door switches on Lada Granta

The VAZ 2190 car is initially equipped with an alarm system. Unfortunately, in the Lada Granta the door switch is installed only near the driver. This creates inconvenience when boarding and disembarking passengers at night, since the interior lighting does not turn on. Also, the absence of an additional signal will not allow you to detect a car thief or thief when trying to open the back door of the Lada.

Characteristics of door limit switches Grants

Apart from the driver's side, there are no door limit switches on the Lada Granta in other opening structures. There aren't even any buttons or standard wiring. The operation of these mechanisms determines the activation of the door open lamp, which lights up on the dashboard. Moreover, the interior light and car alarm react to the actions of the driver or passenger. The average cost of limit switches starts from 150 to 200 rubles. Article 1118-3710199 is the original number and its price is lower than its analogues. The Lada Granta has this device, but it all depends on the modification:

1. The “Norma” package implies the installation of this device in all door structures.
2. The “Standard” package does not imply the presence of limit switches on the seats. There they are replaced with plugs.
3. The “Lux” package will delight the buyer with a full set of sensors, even a rear one.

The activation sensor transmits information using light indicators.

Vehicle configuration

Many Lada car owners are faced with factory defects. The modern Granta model was no exception. After purchasing a vehicle, the owner discovers flaws in the alarm system and interior lighting. At the first inspection of the Lada Grant, it turns out that either there is no standard wiring to the door limit switches, or there are no buttons at all.

Electromechanical devices complete a circuit when the door is opened. In this case, power is supplied to the interior lamp. At the same time, a pulse is sent to the signaling circuit. But AvtoVAZ decided to save on such “little things” as limit switches. Owners of a new car need to eliminate these shortcomings themselves.

There are differences in the alarm connection diagrams between different configurations of the VAZ 2190:

1. Standard. Instead of buttons, plastic plugs are inserted into the seats. There is no wiring in this modification.
2. Lada is normal. The limit switch is on the driver's door, and the remaining mounting holes have plugs, but wiring is installed.
3. VAZ 2190 luxury. There is a complete set of end elements in all doors. But only the driver's limit switch turns on the lighting lamp and the door open indicator on the dashboard. When the passenger door is opened, only the lights will come on.

Installation of limit switches on Lada Granta

An activation sensor in all doors will provide additional comfort. To carry out the installation procedure, you will need special equipment and available materials: lubricant, rubber tips, screwdriver, rag.

Step-by-step algorithm of actions:

1. Remove the rubber tip.
2. Open the housing and remove the limit switch.
3. Remove the block with wires and disconnect.
4. Install a new sensor.
5. Reassemble.

After the basic steps, you need to check the functionality of the device. To connect the limit switch to the power circuit, you will need to connect two terminals: first “+” and then “-”.

If you need to replace the trunk limit switch, then the instructions are identical, you just need to open the trunk lid.

Where is the trunk limit switch of the Lada Granta Liftback

The trunk lid activation sensor is located on the left side, closer to the lamp. However, it is installed only in the “Lux” configuration. Rubber plugs are inserted into “Standard” and “Norma”.

In order to prevent sudden activation of the central locking and door locking, owners optionally install sensors. Considering the simplicity of the procedure, you can do this either independently or by contacting a service station for help from specialists. After installing the trunk end switch into the seat, we lay and connect the electrical wiring. “Plus” is powered from the side lights of the lamp, “minus” can be from the body or on the block with wires. Black with a white stripe is “minus”, red is “plus”.

In the Luxury package, the sensor is built into the trunk lid lock by default. When the lid is closed, the sensor automatically turns off the power from the light.

Finalization of the scheme

The installation or modification scheme will require special equipment to test the electrical circuit. The first place on the list of accessories is a tester and a soldering iron. You will also need a screwdriver, additional wires, electrical tape and a new sensor. When connected, the driver can use the button in the threshold or the door lock contacts.

To do this, you first need to open the sensor housing with a screwdriver and remove the element, remove the block with wires using a screwdriver. Then replace the wire and solder. Insulate the ends and assemble the structure in reverse order. The process is carried out in parallel so that the process involves elements that go to the working positions of the door.

To measure the circuit resistance with a tester, you need to alternately press and release the spherical protrusion.

Design solution to the problem

When replacing or connecting, you only need to restore the originally designed circuit. If no modifications are carried out, then the need to disassemble the locking mechanism and use insulating materials is immediately eliminated. Step-by-step instruction:

1. Open the hood.
2. Loosen the bolt connections and disassemble the device.
3. Unscrew the terminals.
4. Connect the wires from the battery.
5. Pull the limit switch out of the hole.
6. Pull out the switch.
7. Stretch the wires and connect them.
8. Bring the ends out through the hole.

It is important that the wires are no shorter than ten centimeters.

After this, you should check the functionality of the device, and then carry out final assembly.

Troubleshooting

Drivers may encounter various types of malfunctions. Even though the sensor is protected, it is not as reliable as the manufacturers claim. In addition to silicone lubricant, other measures can be used:

1. Install the spring under the rubber cover. If this element is elastic, it will protect the mechanism even at very low temperatures.
2. Remove the protective caps for the winter, but there is a danger that the element will quickly become clogged with dust and dirt.
3. Treat with protective liquid.

Often drivers replace their original limit switch with a part from another manufacturer or install a boot. In this case, the body of the new element is inserted into the standard connector and secured with a self-tapping screw.

Elimination of operational failures

Devices begin to fail at low air temperatures. On the Lada Granta the door switch is protected.

The cause of equipment failures is the protective caps.

The protective shell is made of rubber. The cap loses its plasticity in severe frosts, which prevents the contacts from opening. To prevent failures of limit switches in Lada, the following measures are used:

1. Install the springs under the rubber cover. Spring parameters: diameter - 12 mm, length - 20 mm, wire thickness - about 1 mm. The elastic spring will not let you down even at minus 40°C.
2. We remove the protective caps for the winter. You will get rid of the cause of the problem, but the switch remains defenseless against moisture and dirt.
3. Lubricate rubber surfaces with silicone. Can help with mild frosts (minus 10°C).
4. Treat with water-repellent liquid. This is a temporary measure. Temperature range - up to minus 50°C.
5. We replace Lada brand products with imported analogues from DAEWOO NEXIA or CHEVROLET AVEO doors. When purchasing, you should take a factory sample to compare sizes. The housing is inserted into the standard hole and secured with a self-tapping screw.

Refinement of the Lada Granta alarm system will increase the degree of protection of the car, and interior lighting when opening the rear door will create comfort for passengers.

How to extend service life

Craftsmen are constantly coming up with new ways to extend the service life of factory elements. Some people put coins under the rubber band, fasten the parts with tape, or insert washers. To prevent the switch from freezing or becoming deformed, there are several effective techniques to consider:

1. Spring insert.
2. Replacing standard caps with elements from foreign manufacturers.
3. Silicone Grease.

You should not assume that these actions will grant immortality to the limit switch, but these measures will significantly increase its service life.

Solving problems with door limit switches on Lada Vesta, Granta and Kalina 2

With the onset of frost, some drivers face some problems. For example, the light in the cabin does not light up when the door is opened, the alarm system does not work correctly, etc. The cause of these malfunctions is the door limit switches. Let's look at several ways you can modify them yourself.

Question to AVTOVAZ: How to solve the incorrect operation of limit switches, which become dull in the cold, and the time frame for elimination?

Answer: According to test results at temperatures up to - 30°C, there are no changes in functioning. At temperatures down to -40°C, switching on may occur with a slight delay.

Lada Vesta, Granta and Kalina 2 cars use the same type of door switches. At sub-zero temperatures, their rubber boots (protective rubber caps 11190-3710206-00) freeze and lose their elasticity. As a result, the limit switch rod cannot come out of the housing and the car’s electronic systems believe that the door is closed. Here are some ways to solve the problem:

1. Remove the anthers from the door ends.

No rubber, no problem. But it is worth remembering that the rubber cap is designed to protect the end switch from moisture and dirt. On the other hand, you can remove the anthers only for a short time, while it is frosty outside, and during this period, keep them clean.

2. Replace the limit switch anthers with an analogue one.

It is proposed to install protective caps from another end switch, for example, Toprun (catalog number 104035756, price 50-100 rubles/piece). This end cap is a copy of the original one, but its anthers are made of a material that does not lose elasticity in cold weather. There is no point in changing the limit switches themselves; it is enough to change only the rubber caps.

3. Install the spring under the limit switch boot.

Another budget option for solving the problem, especially when you have springs about 18 mm long and 12-13 mm in diameter at hand. We install them under the rubber caps on the limit switch rod. Now the spring will not allow the boot to remain in a compressed position all the time.

Have you encountered similar problems? How was it solved?

4. Install new type limit switch caps.

From 09/25/2020 On cars of the Lada Vesta family, new caps for limit and door switches began to be installed from the factory.

The product is distinguished by a higher quality, elastic material that is not afraid of even the most severe frosts.

Let us remind you that in order to protect doorways from dirt, it is recommended to install additional door seals (instructions for Vesta, Kalina/Grant). By the way, Vest owners can connect the heated windshield to an additional alarm channel.

The service life of factory rubber caps is limited, only 1.5 - 2 years. The reason lies in the low quality of materials. In winter, drivers often encounter freezing of the limit switch and hardening of the rubber cap. As a result, lighting activation is delayed. The central lock often blocks the doors due to unstable operation of the limit switch. There are several ways to troubleshoot the problem, which we will discuss below.

Installation of door limit switches for Lada Granta and Lada Kalina

In some configurations of Lada Granta/Kalina cars, only one limit switch (switch) is installed on the driver's door from the factory. In some cases (for example, when installing an alarm system), it may be necessary to have limit switches in the rear doors and the front passenger door. You can install them yourself in several ways.

There are two options for installing door limit switches:

1. Install separate limit switches in the door sills on the body.
2. The limit switches are already installed in the door locks, they just need to be connected.

Good day to all!

Like many non-luxury grant drivers, after the purchase I learned with horror that the car only has one door switch, on the driver’s side. Of course, when installing the signaling, 3 more missing limit switches were installed. But who knew that they were already installed in the locks. Even the alarm installer was not in the know. AVTOVAZ simply regretted running the wires into the doors to connect them. At first I thought that the limit switches were even better in rapids, but winter put everything in place. In winter, the rubber band on it becomes stiff and the end switch “sticks” when pressed. But that's not all. I noticed that when the car is loaded (5 people in the cabin), when making sharp turns, sometimes the light in the cabin comes on, so the body plays and the door moves back a little, releasing the limit switch. As a result, almost immediately I wanted to convert everything to limit switches in the locks. But it took me a long time to get ready, the car is almost two years old and I just got around to it. But the work took less than two hours, I did it alone. For now I limited myself to the rear doors. The front ones are completely noisy, I don’t want to open them. YES and they work better.

Installation: As it turned out, the terminal blocks do not have terminals for limit switches, so in addition to the wires, you also need to install terminals. In the vastness of the drive I found that the terminals from the ISO connector of the radio are ideal for this task. Thanks bimulyk for this.

Method No. 1 (separate limit switches)

Required

: limit switches (article 104 035 756 or 1119-3710200), 4 meters of wire.

1. Stretch the wires from the driver's limit switch to the other limit switches in the sills.
2. Remove the plugs in the thresholds and install limit switches instead.
3. Connect the limit switches parallel to the driver's door limit switch (you can have one wire to ground, the other to the driver's door limit switch).

The rubber bands of the end switches can harden in the cold (see modification of the end switches).

Preparing the car before connecting

What controls the central locking? A special block to which the lock actuator wires fit. There are also two wires connected to it, connected to the driver's door microphone. More precisely, this wire is used alone in “Grant”, it has a brown sheath, and the second contact from the “micrik” is connected to ground.

The “micric” itself is located inside the actuator. So, the first piece of advice: 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 configuration, under the trim you will see the following:

1. There are 6 wires suitable for the connector (from 2 microphones and a drive);
2. The cords from the electric drive (pins “2/7”) are not connected, but there is still a brown wire connected to pin “1”;
3. Only those wires that, according to the diagram, should be connected to contacts “4/6” are missing.

Connecting the signaling means that the wires from contacts “2/7” are still connected to the central locking control unit. The cords coming from the three actuators are always connected to the standard unit. You need to connect a fourth one, if this is not done by the factory. You may have to lay a two-wire cable from the door to the central lock control unit:

The central locking control unit is located under the fuse block, it is designated BUBD-2190.

Here's how one of the car owners coped with the task:

The cords that come out of the door are connected to the wires of the standard terminal block. The following connector pins are used: “3” and “4”. The main thing is not to confuse them. Take another look at the diagram to see what exactly we are talking about.

Method No. 2 (limit switches in locks)

Required

: 4 meters of wire, terminals from the ISO connector of the radio, remove the door trims.

1. Remove the block by pressing on the plate.
2. Open the plug on the connector.
3. Insert the terminals into pins 1 and 3 until they click.

1. Remove the block, pull the fungus down.
2. Open the plug on the connector.
3. Insert the terminals into contacts 1 and 4 (or 4 and 6 depending on the configuration and year of manufacture of the vehicle) until it clicks.

We connect the limit switches parallel to the driver's door limit switch (you can have one wire to ground, the other to the driver's door limit switch).

If you cannot disconnect the connector without removing the lock:

1. Remove three bolts securing the lock and one bolt securing the glass guide.
2. Remove the door handle and door lock button.
3. Disconnect the rods and remove the lock.

Programming the duration of control pulses

Even if the alarm is connected correctly, it is not a fact that the owner will be able to control the locks from the key fob. The point is that it is necessary to correctly select the duration of the control pulse (for locking and for opening). There is no need to make it too large so as not to overheat the actuators.

See what exactly the manufacturer Starline offers. We can set the pulse duration to 0.7 s, which should be enough. The value “3.6” will be redundant at the same time.

The “Lux” package has the following property: after 15 minutes of inactivity, the electronics “fall asleep”. It may take an extra boost to wake her up. So, try to use the option that provides for a double pulse. The main thing is not to activate the “comfort” option, which uses a 30-second duration. To connect the signaling with “comfort”, you need to install an additional unit in Grants (AvtoVAZ does not produce it). We wish you success.
