On-board control system VAZ 2110 and its purpose
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 onboard control system, or rather the display unit of the onboard 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 block. Its cost may fluctuate, but the price will remain within 1000 Russian rubles.
After disconnecting this system and performing 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 devices. 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?
