On the passengers of the "Tenth Family" next to the display unit, a clock or computer is always installed. Now such computers are called " onboard computers"(BC). The computer display when the ignition is turned off shows the time, but this is not its only function! We list all the capabilities of the on-board computer on the VAZ-2112, and the instruction attached by the VAZ will help us in this. The instructions were copied tables that are important when setting up.

What kind of BC is we talking about? The answer is visible on the video.

The appearance of the facial panel is shown in the photo below. You need to remember the main keys: 1, 2, 3 and 5. All functions are divided into three groups. By pressing the 1 button, you can scroll through the functions of the first group. The same refers to other keys.

Stable BC for Lada-112 hatchback

Asks, why do you need a button 5? Being in any of the three groups, additional functions use this button. By the way, their number is two.

In each group, additional functions are different.

Example with scrolling

When the ignition is turned off, we see the clock on the display. Let's try to turn on the ignition and press the 1. The button itself can be pressed any number of times - the function switches cyclically. Their number is three.

Group of functions "Time"

If additional functions are needed, click on the button 5. We reviewed how to use a regular onboard computer on the VAZ-2112, but the instruction is suitable for any "dozens".

Operation of the BC in different modes

The above is said how to use the BC in the "time" mode. The group "Time" is the first, but there are two more - "fuel", "path". We give the table for them.

Group of Functions "Fuel"

The above is the table for the buttons 2 and 5.

Group of functions "Path"

Here are features included with buttons 3, 5.

Programming Instructions

We will change different settings. And try to turn on the alarm clock, change the brightness of the backlight, etc. Thus, the computer programming on the VAZ-2112 is referred to also.

Alarm clock in the car - the thing you need

It remains to understand how to turn off the alarm clock. Do all the steps before setting the clock value, and then press the button 1. The alarm must be turned off!

How to set up calendar and watches

We reached the most difficult chapter. We immediately go to action:

For quick adjustment, perform step 1 and step 2. If then click on button 1, the readings of the clock are rounded: it was 13:57, and will be 14:00. Or otherwise: it was 14:05, and will be 14:00.

Our editorial 2112 with Gamma GF 212 BC. We are fully satisfied with them.

The most popular non-standard BC on the VAZ-2110 is the GAMMA GF 212 model.

Its cost about 2500 rubles . Installing a simple, you just need to connect to the K-line in the diagnostic connector and bring the power wire.

There are such useful functions like blowing candles and so on. We can only recommend it among a large set of models presented in the market.

Modern cars are equipped with a large number of electronic devices: ignition switch switches, engine operation control units, diagnostics, onboard IT computers. with some of these devices installed on domestic cars VAZ and gas, we will introduce our readers. This information may be useful as specialists, tech and fans engaged in the repair of such equipment. Today it will be about the indication block of the board of control system.

Block indication side System Control (BSK-10, then the unit) is designed to display the state of the vehicle nodes with ten light and one sound alarms. The list of controlled parameters and the colors of the corresponding light signals are given in the table.

The working block may be in one of five modes:

1. "Disabled" - the key is missing in the ignition lock.

2. "Waiting" - the key in the ignition lock in the "Off" position. If the driver's door is open, the unit registers the event "Forgotten key in the ignition lock" and submits sound signal Within 6 s.

3. "Pre-deputy control of the alarms" - when turning the key to the "Ignition" position. Duration of 4 s mode. One beep is served, and all light alarms are turned on by 4 s. Problem monitored " insufficient level Oils "," Insufficient coolant level "," Insufficient level of washing fluid ", and the value is remembered, however, the light signals are not turned on until the end of the mode.

4. "Pre-deputy control of parameters" - at the end of the "Pre-departmental control of the alarms" and pause in 1 seconds. The duration of the regime is 6 s. Steight light indicators first blink for 6 seconds with a frequency of 1 Hz, then glows constantly before eliminating the fault or the key turning to the "off" position. The sound signaling is turned on simultaneously with light signals by 3 s.

Registered malfunctions "Insufficient oil level", "Insufficient coolant level", "Insufficient level of washing liquid", "Fault of lamps of stop signals and overall lights"And" brake shoe wear "is remembered until the key turns to the" off "position.

5. "The control of the parameters when the engine running" begins at the end of the "Pre-deploy control of parameters". The monitoring of malfunctions "Insufficient Oil Level", "Insufficient Coolant Level", "Insufficient Imo-Fluid Level", Problem Control "Unclosed Doors", "Unsecured Safety Straps", "Fault Lights of Stop Signals and Overall Lights", "Wear brake shoes"continues.

The device consists of two main parts (Fig. 1): microprocessor and indicator mounted on the control board A1 and on the indication board A2, respectively. Both boards are installed in the plastic case.

(Click to enlarge)

The appearance of the block is shown in Fig. 2. 15-pin connector is used to connect power and sensors.

The output signals of the sensors are coming from the contacts of the XP1 connector to the inputs P0.0-P0.5, P2.0-P2.5 microcontroller DD3 through the matching chains of A1V1-A1V12 and Schmitt Triggers DD1, DD2. Outputs P1.0-P1.7, P3.1, P3.2 microcontroller are designed to control the transistor keys A2B1-A2B10, which, in turn, commute the HL1- HL10 LEDs. To form a bell signal, imitating the ringing of the bell, serves as a dynamic head of B1, which is connected through a C9 separator condenser to the output of the amplifier on the transistors VT7, VT8, controlled by the RZ.B, P3.7, DD3 microcontroller.

When the key is inserted into the car ignition lock, the supply voltage comes from the contact 11 of the XP1 connector through the VD9 diode, which protects the block from the ransom to the voltage stabilizer, made on the VT1-VT6 transistors. The VD11R8R9VT6 circuit turns off the power of the unit if the voltage in the on-board network exceeds 24 V. The stabilizer provides a minimal voltage drop (not more than 0.6 V at full load) and allowing the pulse input voltage to 150 V.

The DD3 microcontroller contains a built-in clock generator, working with an external ceramic resonator CSA-8.0MTZ of the company Mshatan8MHz.

Resetting a fixed duration for a DD3 microcontroller after supplying the supply voltage or if it decreases below 4.2 V generates a node ("Supervisor"), consisting of a threshold element on the VT10 transistor, VD12 stabitron and a single manufacturer on elements DD4.3, DD4.4 . In standby mode (Ignition is turned off, the front doors are closed) The DD3 microcontroller is located in the "sleep" condition, 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 open any front door, the node on the DD4.1 element and the VT9 transistor generates an interrupt (log. 0) at the output of the DD3 microcontroller, withdrawing it from the "sleep" state.

The block indicates the open state of each car door. To save an individual signal from each door switch and include lighting in the cabin when opening any door, VD5-VD8 diodes are applied. VD1-VD4 diodes prevent supply voltage to the block through the lighting lamp of the car interior.

The block mainly applies elements for surface mounting. CONDENSER C9 - Jamicon SKR101M1EE111VM SKR101M1EE11VM (admissible to a similar), C3 condenser - tantalum size D for surface mounting, all other capacitors and resistors of sizes 06033, 0805 and 1206. MJE15031 and 2N5401 transistors can be replaced by KT851A and CT6116A, and transistors SUP847 and SPE857 - on CT3130A-9-CT3130ZH-9 and CT3129A-9-KT3129D-9, respectively.
