The on-board control system of the VAZ 2110 is represented by several sensors and signaling devices that help eliminate shortcomings in the operation of the vehicle system. At one moment they may cease to be necessary, and at another they can save from unexpected breakdowns or even save a person’s life.
Their serviceability must be constantly monitored. In order for the on-board indication unit of the VAZ 2110 control system to always remain in working condition, it is necessary to know the amount of sensor data.
All about the onboard system
Below is a list of sensors available in the VAZ 2110 car system?
- Alarm low oil level in the crankcase.
- Liquid level alarm in the wiper system (see).
- Insufficient coolant alarm.
- Open door alarm.
- Signaling during a malfunction of brake lights and parking lights.
- Front brake lining wear warning.
- Seat belt alarm.
Each of these alarms has several modes of operation:
- Off state.
- Standby mode.
- Control before leaving.
- Basic parameter control mode.
Off state
The off state of the on-board control system occurs when the ignition key is not in the keyhole.
Standby mode
The standby mode takes place when the ignition key is only inserted into the socket, but not activated.
Pre-departure check
If the door is open in this position, the door open alarm will be activated. In this case, you must either close the door or turn the ignition key and start the car engine.
It is at this moment that the transition to pre-departure control occurs.
Basic Mode
At the last level of the main parameter control, the alarm can be activated:
- Signaling of the parameter that deviated from the nominal value.
- Together with the light signal, an audible signal can be given, which will notify the driver of a malfunction within 3 seconds.
- If another failure occurs at the same moment, the system starts to work in priority mode, which is given to the problem more important. At this point, there is a constant highlighting of a less important breakdown.
Trouble-shooting
To eliminate the malfunctions indicated by the alarm, it is necessary to take important steps to eliminate it:
- If the oil shortage alarm is on, add oil to the engine crankcase.
- Washer system alarm - top up washer fluid.
- Alarm - bringing the coolant level to normal.
- Open door alarm - close the doors or remove the key from the ignition.
- Malfunction of brake lights and marker lights - correct the operation of these systems.
- Lack of brake pads - fix the breakdown.
- Belt alarm - fasten the belts in the required position.
All these signaling indicators are placed in a special place and are called the on-board system display unit on the VAZ 2110. At the time of operation, they emit both a light signal and a sound signal.
There are two sensors that are constantly working when the engine is running. This is the brake pad wear sensor.
If they are faulty, the on-board control system, or rather the display unit of the on-board systems of the VAZ 2110, will not show a reliable result. It is necessary to constantly monitor the operation of these sensors.
It should be noted that at the moment the ignition key is turned, all indicators on the dashboard are fully tested. At this point, it is necessary to check the operation of each alarm lamp.
Turns on when the door is open. You need to carefully monitor these devices, as their working condition is necessary and very important.
Repair of the control system
To repair this control system, you must do the following:
- First of all, you need to remove the "negative" terminal from the battery.
Note: For ease of access to the control system, actions take place in the cabin, since it is here that the display unit of the on-board control system VAZ 2110 is located.
- A screwdriver slightly pry the clock in the car.
- After removing them from the connector, it is necessary to disconnect the wire fastening.
- The clock is set aside.
- The display unit of the onboard control system is removed through the free space from the clock.
- Disconnect all wire fasteners.
After performing this work, it is necessary to repair this unit or replace it with a new one. This work is best entrusted to specialists if the driver does not have the skills to work with electronic equipment.
You may have to make a purchase of this unit. Its cost may fluctuate, but the price will remain within 1000 Russian rubles.
After disconnecting this system and carrying out a repair/replacement, it is necessary to put all the parts back in their original place in the opposite order. One of the problems can be an electrical wire that has become disconnected or burned out.
In this case, it is necessary to analyze the signal received from the sensors over the entire distance of the wire, using special instruments. Such a diagnosis must be carried out carefully.
In any case, you can carry out the above work yourself. To do this, it is recommended to watch the corresponding replacement video and use the photo as a visual aid.
With your own hands, you need to do everything carefully, as required by the instructions, and then everything will turn out well. And why pay extra money to specialists, if everything works out like that?

Lada VAZ-2110 (2111, 2112). On-board monitoring system display unit
The display unit is installed in the console of the instrument panel and gives out sound and light alarms about open car doors, unfastened seat belts, malfunction of outdoor lighting lamps or their circuits, wear of the front brake pads, insufficient level of: engine oil, coolant, washer fluid. The unit also turns on and off (with a delay) the interior lighting when any door is opened.
The unit is off when there is no key in the ignition. As soon as the key is inserted (but not yet turned), the unit reacts to the opening of the driver's door with an intermittent sound signal (buzzer) for 8±2 s, which means "forgotten key in the ignition lock". The alarm is deactivated when the door is closed, or the key is removed, or turned from the "0" position.
After turning the key to the "Ignition" position, the unit enters the test mode. At the same time, all indicator lights and a buzzer turn on so that the driver can verify that they are working. At the same time, signals are received from level sensors (coolant, washer fluid and engine oil).
If any sensor shows an insufficient level, at the end of the test, the corresponding indicator starts flashing and a buzzer sounds for 8±2 s. After that, the indicator lights up continuously until the ignition key is turned to position "0".
After starting the engine, the level sensors are not polled. Only the signals from the brake pad wear sensor, the relay for monitoring the health of the lamps (parking lights and brake lights) and the door limit switches are processed. If a "Brake pad wear", "Lamp burned out" or "Door not closed" fault occurs, the buzzer will sound and the corresponding indicator light will flash. After 8 ± 2 s, it lights up with a steady light and the buzzer turns off. After closing the door, the indicator goes out, in case of other malfunctions, it continues to burn until the key is turned to position "0".
The coolant (and washer) fluid level sensor consists of a plastic tube sealed at the bottom with a reed switch inside and a float with a magnet put on the tube. Oil level sensor - with brass tube. As soon as the reed switch enters the magnetic field, its contacts are closed. The coolant and washer fluid level sensors have a two-contact block, the oil level sensor has a single-contact one (the second contact is the car's ground).
The brake pad wear sensor is installed in a special hole in the front brake pad and connected to the vehicle wiring with a single-terminal connector. Sensors are sold complete with pads; when replacing them, the sensor is installed on the inner pad.
Scheme of connections of control devices (view from the back side): 1 - control lamp of the fuel reserve; 2 - lighting lamps for the instrument cluster; 3 - control lamp of the right turn; 4 - control lamp of the left turn; 5 - coolant temperature gauge; 6 - control lamp for outdoor lighting; 7 - oil pressure control lamp; 8 - control lamp of the parking brake; 9 - battery charge control lamp; 10 - tachometer; 11 - control lamp "Check engine"; 12 - speedometer; 13 - brake fluid level control lamp; 14 - alarm warning lamp; 15 - control lamp high beam headlights; 16 - fuel gauge.
Lada VAZ-2110 (2111, 2112). Trip computer
On some cars, instead of a clock on the instrument panel, a trip computer can be installed that shows the time since the start of the trip, fuel consumption, average speed, estimated mileage on the remaining fuel, and the air temperature outside the car. In addition, it can function as an alarm clock.
Modern cars are equipped with a large number of electronic devices: ignition system switches, engine control units, diagnostics, on-board computers, etc. e. We will introduce our readers to some of these devices installed on domestic VAZ and GAZ cars. This information can be useful to both specialists, tech and amateurs involved in the repair of such equipment. Today we will talk about the display unit of the onboard control system.
The on-board control system display unit (BI BSK-10, hereinafter referred to as the unit) is designed to display the state of vehicle components using ten light and one sound signaling devices. The list of controlled parameters and the colors of the corresponding light signals is given in the table.
This device with the designations 12.3860 and 2110-3860010-04 is installed on all modifications of cars of the VAZ-2110 family. The variant of the block described here was produced with minor changes from 1998 to 2002.
The operating unit can be in one of five modes:
1. "Off" - the key is not in the ignition.
2. "Waiting" - the key in the ignition in the "off" position. If the driver's door is open, the unit registers the "forgotten key in the ignition" event and beeps for 6 seconds.
3. "Pre-departure control of signaling devices" - when the key is turned to the "ignition" position. The duration of the mode is 4 s. One beep sounds and all lights come on for 4 seconds. The malfunctions "insufficient oil level", "insufficient coolant level", "insufficient washer fluid level" are monitored and their meaning is memorized, however, the light signals do not turn on until the end of the mode.
4. "Pre-departure control of parameters" - after the end of the "pre-departure control of signaling devices" mode and a pause of 1 s. Mode duration - 6 s. The triggered light indicators first flash for 6 s at a frequency of 1 Hz, then glow continuously until the malfunction is eliminated or the key is turned to the "off" position. The sound signaling device turns on simultaneously with the light signals for 3 s.
The registered malfunctions "insufficient oil level", "insufficient coolant level", "insufficient washer fluid level", "failure of stop lamps and parking lights" and "brake pad wear" are stored until the key is turned to the "off" position.
5. "Parameter control with the engine running" begins after the end of the "pre-departure parameter control" mode. The fault monitoring "insufficient oil level", "insufficient coolant level", "insufficient washer fluid level", fault monitoring "unclosed doors", "seat belts not fastened", "malfunction of stop lamps and side lights", "brake wear block" continues.
The device consists of two main parts (Fig. 1): a microprocessor and an indicator mounted on the control board A1 and on the indication board A2, respectively. Both boards are installed in a plastic case.

The appearance of the block is shown in fig. 2. A 15-pin connector is used to connect power and sensors.
The output signals of the sensors come from the contacts of the XP1 connector to the inputs P0.0-P0.5, P2.0-P2.5 of the DD3 microcontroller through matching circuits A1B1-A1B12 and Schmitt triggers DD1, DD2. The outputs P1.0-P1.7, P3.1, P3.2 of the microcontroller are designed to control transistor switches A2B1-A2B10, which, in turn, switch the LEDs HL1-HL10. To form an audio signal that simulates the ringing of a bell, the dynamic head HA1 is used, which is connected through an isolation capacitor C9 to the output of an amplifier based on transistors VT7, VT8, controlled by the outputs P3.b, P3.7 of the microcontroller DD3.
When the key is inserted into the ignition lock of the car, the supply voltage is supplied from pin 11 of the XP1 connector through the VD9 diode, which protects the unit from polarity reversal, to a voltage regulator made on transistors VT1-VT6. The VD11R8R9VT6 circuit turns off the power supply of the unit if the voltage in the on-board network exceeds 24 V. The stabilizer provides a minimum voltage drop (no more than 0.6 V at full load) and allows the supply of a pulsed input voltage of up to 150 V.
The DD3 microcontroller contains a built-in clock generator that works with an external ceramic resonator CSA-8.0MTZ from MSHATA at 8 MHz.
A fixed duration reset signal for the DD3 microcontroller, after the supply voltage is applied or if it drops below 4.2 V, generates a node ("supervisor") consisting of a threshold element on the VT10 transistor, a VD12 zener diode and a single vibrator on the elements DD4.3, DD4.4 . In standby mode (ignition off, front doors closed), the DD3 microcontroller is in a "sleep" state, while the current consumed by the unit does not exceed 7.5 mA. If the key in the lock is turned to the "ignition" position or any front door is opened, the node on the DD4.1 element and the VT9 transistor generates an interrupt (log. 0) at the output РЗ.З of the DD3 microcontroller, bringing it out of the "sleep" state.
The block indicates the open state of each car door. To save an individual signal from each door switch and turn on the interior lighting when any door is opened, VD5-VD8 diodes are used. Diodes VD1-VD4 prevent the power supply to the unit through the car's interior lamp.
The block mainly uses elements for surface mounting. Capacitor C9 - aluminum oxide SKR101M1EE11VM from JAMICON (replacement with a similar one is acceptable), capacitor C3 - tantalum size D for surface mounting, all other capacitors and resistors of sizes 0603, 0805 and 1206. Transistors MJE15031 and 2N5401 can be replaced with KT851A and KT6116A , and the transistors VS847 and VS857 - on KT3130A-9-KT3130Zh-9 and KT3129A-9-KT3129D-9, respectively.

Every owner of a VAZ car wants to make a work of art out of his car. The main obstacle to achieving this goal is that the cars of the VAZ family are very boring and therefore you have to do a lot to stand out from the crowd. It is probably better to start tuning cars from the interior, since first of all it should be comfortable, and then beautiful.
Let's start with the fact that we need to make a beautiful color illumination in the interior of the VAZ 2110 car. This article will describe in detail the process of changing the backlight of the panel of a VAZ 2110 car, or to be more precise, replacing the backlight of the BSK with a car dashboard. So, let's begin. In order to make a bright backlight on the BSC, we need to work with LEDs and plexiglass. On some cars of this family, the BSC inserts have a transparent structure, and on some they do not. In my case, the insert was opaque, so I had to sweat a little to get it to the right state. Let's move on to the process. To begin with, I dismantled the BSC and sawed it out of plexiglass, a small rectangle slightly larger than the pattern of the typewriter on the BSC. Next, I drilled a small hole in it for the LED, about 3 mm in size.
Now we cut a hole in the frame, which is located under the insert with a pattern.
In order for the LEDs not to shine on the open door indicators, you need to make a small partition between the lamps. As a partition, I used an opaque film. Now the light barrier is ready, it remains only to make the backlight itself. Let's prepare the LEDs. In order for the LEDs not to shine directionally, we need to process them and make the surface matte. For surface treatment, we need fine sandpaper. We process the LEDs and proceed to soldering. We attach 1.5 kΩ resistors to the long contact of the LEDs so that the LEDs have resistance. If the resistors are not soldered, then the resource of the LEDs will be much less. Now you can connect the LEDs and power wires. We connect the LEDs to the contacts of the standard backlight and check everything in action.
In my case, everything did not work out as I expected, one of the LEDs burned out, even with a resistor, because I forgot to disconnect the terminal from the battery. So before work, it is best to disconnect the negative wire from the battery. The work had to be redone. A few minutes later, I had already completely replaced the LEDs and finished the job. Checked everything in the case, it works properly. The results made me very happy, the BSC panel glows very beautifully, the eye is already happy.
This work took quite a bit of time, about 90 minutes and only a few rubles to buy LEDs and resistors. At night, colorful illumination reigns in the cabin. A few days later, I also replaced the instrument panel lighting, air ducts and made a starry sky on the ceiling lining. Now it is very pleasant to sit in the car. Friends are all delighted with my car. Well, that's all, we made a beautiful illumination of the BSC with our own hands, while not spending a lot of time and money. Thank you for attention. Bye.
Onboard control system (BSK)- a very useful thing in the car! But for some reason, on the "Tens" the sensors are polled only when the ignition is turned on. That is, if you added liquid to the tank, then in order for the indicator on the BSC to go out, you need to turn off / on the ignition. In this article I will show you how finalize the BSC for real-time operation.
Default BSC polls all sensors only when the ignition is turned on. This means that if the coolant level has dropped (due to its leakage) or the windshield washer water runs out, the driver will not know about it until the next time he turns on the ignition.
The BSC block provides the following parameters:
1. Low oil level indicator - and so it works normally with its 10-minute delay, so we don’t touch it.
2. The lamp malfunction indicator also works normally when the engine is running.
3,4,5,6. Four open door alarms, their work is also quite satisfactory.
Remaining for alteration:
7. Signaling device for insufficient level of washer fluid.
8. Signaling device for insufficient coolant level in the expansion tank.
9. Front pad wear indicator.
10. The signaling device of not fastened seat belts of the driver.
The last two parameters do not work from the factory, because. sensors are not installed, I used them for other purposes:
1) connected to the pad wear indicator washer reservoir level sensor
2) to the signaling device for not fastened seat belts rear window washer reservoir level sensor.
Altered signaling devices for level drop in the expansion tank and in the washer tanks.
The meaning of this refinement is to disconnect the LEDs of the indicators we need from the board and connect them directly (through resistances) to the BSC plug.
2. Old model with a long body. Unlike the new sample, there is a lot of free space and the plug is located separately from the board, connected to it by wires. I have an old block.
3. Then, the same wires, only on the other hand, soldered from the plug, soldered them to their places of resistance, and soldered the wires themselves to the resistances. The resistance used was 620 ohms, with a power of 0.125W.
After such refinement of the BSC, the indicators work with the ignition on, and light up immediately when the sensor is triggered. The sound signaling device does not work with them (when the liquid level drops, on uneven roads, it tortures with its beeping.)
Instead of the "belts" and "pads" icons, I made my own fluid level icons.
My friend, Roma112, drew a layout of a new insert in CorelDRAW with new icons" fluid level in the headlight washer reservoir" And " fluid level in the rear window washer reservoir". I printed this layout on a phototypesetter and laminated it with a matte film.
