Connecting the on-board computer to the VAZ 2114

Just a few years ago, the electronic system of a car was considered a luxury innovation, but recently many cars are equipped with this element.

Most motorists would like to have a car stuffed with all the technical innovations. But unfortunately, not all cars of the VAZ family are equipped with an electronic system. Installing the on-board computer on the VAZ 2114 on your own should not cause any difficulties.

The functionality of electronics is quite extensive, it has a large number of various programs aimed at improving the operation of the car and monitoring its technical condition. This system with the highest accuracy determines many parameters of the machine, for example: speed mode, temperature indicators of the braking fluid, the voltage level inside the machine system and much more. Moreover, the indicators of the on-board computer are many times more accurate than the indicators of regular devices. The functionality of the electronic on-board system is very diverse.

In addition to determining the accuracy of indicators in the operation of the machine, on-board electronics do an excellent job of diagnosing all vehicle systems and determines fault codes. Difficulties with deciphering the codes should not arise, because. on-board computer instructions contain all the necessary decryption.

The advantages of electronics are quite tangible, it is possible, without visiting the service center, to independently identify all the problems that have arisen during the operation period, and eliminate them in a timely manner. An important point is that the system helps to avoid quite serious consequences of a malfunction due to timely diagnosis.

Another advantage of this system is the equipment with sound alarm and light alarm. This type of alarm also informs the car owner about problems that have arisen in the network of the car, or informs about the engine overheating.

Which on-board computer to put on the vaz 2114

The main point that you need to be guided by when choosing an on-board computer for the VAZ 2114 is the support for the VAZ2114 ECU program. In addition, there is no need to save money, more expensive electronics will be able to check the condition of the machine and signal a malfunction in a timely manner.

Errors on-board computer vaz 2114

To check the computer, you need to reset the daily mileage on the dashboard and turn on the ignition at the same time. Then, by pressing the key at the wiper lever, you will see on the display the computer firmware version with error codes, if any.

Main error codes:

• 2-The mains voltage of the machine is too high.
• 3-fuel level sensor.
• 4-liquid cooling temperature sensor.
• 5-Violation of the functioning of the temperature sensor overboard.
• 6-motor overheating.
• 7-critically low oil pressure.
• 8-deficiencies in the braking system.
• 9-The battery is discharged.

The most common on-board system errors are:

1. Code 4, basically pops up on an insufficiently warmed up engine, or when the sensor is turned on, indicating the amount of fuel.
2. Code 6 indicates an overheated engine.
3. Code 8, with a shortage of brake fluid in the system.

Having identified the existing errors, they can be reset, it is enough to press and hold the daily mileage key of the car for a while.

Important!

Before making a transaction to purchase a car, be sure to check the on-board system. Make sure there are no system errors. Or you will discover curious facts about the condition of the car. For example: engine heating, oil pressure, etc.

How to connect an on-board computer to a vaz 2114

Before proceeding with the installation, it is necessary to decide for which functions the VAZ 2114 on-board computer is needed. Before deciding on the choice of an electronic system, you need to pay attention to the characteristics of the machine. Of course, it is not advisable to buy a very complex system for an ordinary car, or too expensive for a budget class car. It is enough to purchase a system that includes a monitor, the necessary set of wires and, accordingly, a processor.

Then determine the location for mounting the electronic system monitor. The best solution would be to mount in the center of the console if space permits. If there is no free space, the monitor can be mounted on a torpedo; accordingly, an external housing is required.

The next step is to place the processor itself. Do not forget that it is necessary to provide free access to all ventilated holes of the processor, the case must be attached in a certain place. The wires must also be passed through a special tube that protects them from external negative influences.

After installing all the elements, connect the wiring. To display the technical condition of the machine, you need to connect the on-board computer to the center of the machine. After completing the installation process, turn on the system and install the necessary programs. The final step will be the setup.

If there are problems with the operation of the electronic system, for example, the on-board computer VAZ 2114 does not work. Most likely, the problem lies in incorrectly connected contacts or incorrectly implemented settings. To resolve this issue, it is enough to check all connections and check, or check the existing settings according to the instructions.

How to install an on-board computer on a vaz 2114?

9 - and pin connector

First you need to remove the stub on the panel. After removing it, you need to find a bundle of wires with a 9-pin connector, it is available on all VAZ models. Connect the connector to the on-board computer, be sure to draw a K-line, for this:

1. Connect a wire 1 m long to the second contact of the connector block.
2. Lead the other end of the wire to the diagnostic block under the dashboard, so that the process does not cause inconvenience, you can unfasten the panel on the right.
3. Connect the wire to the diagnostic block, through the M-socket in the presence of the EURO 2 block, or to socket 7 in the presence of the EURO 3 block ( there are cases of mounting the EURO 3 block upside down, be sure to pay attention to this!).
4. Connect the on-board computer, install it in the designated place and conduct a test.

The presented Scheme for connecting the on-board computer to the VAZ 2114 shows in detail the procedure.

How to remove the on-board computer on the vaz 2114

Unfortunately, many drivers are not satisfied with the operation of the electronic system of the car installed during the assembly of the VAZ. This gadget can be removed without any problems.

The first step is to study the instructions for the machine, it provides for the process of dismantling the on-board system.
