Modern cars are equipped with a large number of electronic devices: ignition system switches, engine control units, diagnostics, on-board computers, etc. with some of these devices installed on domestic cars VAZ and GAZ, we will introduce our readers. This information can be useful to both professionals, tech and amateurs engaged in the repair of such equipment. Today we will talk about the display unit of the on-board monitoring system.
The display unit of the on-board monitoring system (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 monitored parameters and the color of the corresponding light signals is given in the table.
The operating unit can be in one of five modes:
1. "Off" - the key is not in the ignition lock.
2. "Waiting" - the key in the ignition switch in the "off" position. If the driver's door is open, the unit registers the "forgotten key in the ignition switch" 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 warning lights turn on for 4 seconds. The malfunctions "insufficient oil level", "insufficient level of coolant", "insufficient level of washer fluid" are monitored, and their value is remembered, 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 annunciators" mode and a pause of 1 s. The duration of the regime is 6 s. Triggered light indicators first blink for 6 s with a frequency of 1 Hz, then light up 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.
Registered faults "Insufficient oil level", "Insufficient coolant level", "Insufficient level of washer fluid", "Malfunction of brake lamps and side lights"and" brake pad wear "are stored until the key is turned to the" off "position.
5. "Parameter control with the engine running" starts after the end of the "pre-departure parameter control" mode. The monitoring of malfunctions "insufficient oil level", "insufficient level of coolant", "insufficient level of washer fluid", malfunction monitoring "open doors", "unfastened seat belts", "malfunction of brake light and side lights", "wear of brake pad "continues.
The device consists of two main parts (Fig. 1): a microprocessor and an indicator mounted on the A1 control board and on the A2 indication board, respectively. Both boards are installed in a plastic case.
(click to enlarge)
The block appearance 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 microcontroller DD3 through matching circuits A1B1-A1B12 and Schmitt triggers DD1, DD2. Outputs P1.0-P1.7, P3.1, P3.2 of the microcontroller are designed to control transistor switches A2B1-A2B10, which, in turn, switch LEDs HL1-HL10. To generate a sound signal that simulates the ringing of a bell, a dynamic head HA1 is used, which is connected through an isolating capacitor C9 to the output of an amplifier on transistors VT7, VT8, controlled by the outputs РЗ.б, Р3.7 of the microcontroller DD3.
When the key is inserted into the car's ignition switch, 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 stabilizer made on VT1-VT6 transistors. The VD11R8R9VT6 circuit turns off the power to the unit if the voltage is on-board network exceeds 24 V. The stabilizer provides a minimum voltage drop (no more than 0.6 V at full load) and allows a pulse 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 by MSHATana 8MHz.
A fixed-duration reset signal for the DD3 microcontroller after the supply voltage is applied or if it drops below 4.2 V is generated by a node ("supervisor") consisting of a threshold element on a VT10 transistor, a VD12 zener diode and a one-shot on DD4.3, DD4.4 elements ... 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 PZ.Z pin of the DD3 microcontroller, bringing it out of the "sleeping" state.
The block indicates the open state of each door of the car. To keep an individual signal from each door switch and turn on the interior lighting when opening any door, VD5-VD8 diodes are used. Diodes VD1-VD4 prevent the supply voltage to the unit through the car interior lighting 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 standard sizes 0603, 0805 and 1206. Transistors MJE15031 and KT6851A can be replaced with transistors VS847 and VS857 - on KT3130A-9-KT3130Zh-9 and KT3129A-9-KT3129D-9, respectively.
On cars of the "Tenth Family", a clock or a computer is always installed next to the display unit. Now these computers are called "on-board computers" (BC). The computer display with the ignition off shows the time, but this is not its only function! We will list all the capabilities of the on-board computer on the VAZ-2112, and the instructions supplied by the VAZ will help us with this. Tables were copied from the instructions, which are important when setting up.
What bookmaker are we talking about? The answer is shown in the video.
The appearance of the front panel is shown in the photo below. You need to memorize the main keys: 1, 2, 3 and 5. All functions are divided into three groups. By pressing button 1, you can scroll through the functions of the first group. The same applies to other keys.
Regular BC for the hatchback "Lada-112"
The question is, why do we need button 5? Being in any of the three groups, this button activates additional functions. By the way, their number is equal to two.
Each group has different additional functions.
Swipe example
When the ignition is off, we see a clock on the display. Let's try to turn on the ignition and press key 1. The button itself can be pressed any number of times - the functions are switched cyclically. Their number is three.
Function group "Time"
If you need additional functions, press button 5. We have seen how to use the standard on-board computer for VAZ-2112, but the instruction is suitable for any "Tens".
BC operation in different modes
It is said above how to use the BC in the "Time" mode. The "Time" group is the first, but there are two more - "Fuel", "Way". We give tables for them.
Function group "Fuel"
Above is the table for buttons 2 and 5.
Function group "Path"
The functions activated by buttons 3, 5 are shown here.
Programming instructions
We will change different settings. We will also try to turn on the alarm, change the brightness of the backlight, etc. Thus, computer programming on the VAZ-2112 is also related to operation.
Configuring the fuel level sensor
The tank is initially empty. Turn on the "Fuel level" function (2-5) and press button 4 for more than two seconds. Then we follow the steps:
- Press button 3 for one second until the sound signal appears;
- We fill the tank with three liters of fuel. Wait 10-20 seconds and repeat step 1;
- Repeat steps 1 and 2 until 39 liters are filled.
We activate the overspeed alarm
By pressing button 3 we turn on the "Average speed" function. Press the key 4. Next, use the buttons 5 and 6 to set the required numbers. Finally, press the button 4.
To disable the option, use a high threshold value: 190 or 200 km / h.
Change the brightness of the backlight
We use function 1-3 "Time with stops". Press button 4. Use keys 5 and 6 to adjust. Press button 4.
Alarm
Go to the "Alarm" option (an additional function in the "Clock" list). Press button 4. Next, set the hour value (keys 5 and 6), press button 4, set the value of minutes (keys 5 and 6). By pressing button 4, the alarm is activated.
An alarm clock in a car is a necessary thing
It remains to figure out how to turn off the alarm. Follow all the steps until you set the hour, and then press the button 1. The alarm should turn off!
How to customize your calendar and clock
We have reached the most difficult chapter. Let's go straight to the action:
For quick adjustments, follow step 1 and step 2. If you then press button 1, the hours will be rounded up from 13:57 to 14:00. Or otherwise: it was 14:05, but it will become 14:00.
Our editorial 2112 with BC Gamma GF 212. We are completely satisfied with it
The most popular non-standard ammunition vehicle on the VAZ-2110 is the Gamma GF 212 model.
Its cost about 2500 rubles ... Installation is simple, you just need to connect to the K-line in the diagnostic connector and bring the power wires.
There are such useful functions as blowing out candles and more. We on our own can only recommend it among the large variety of models on the market.
