On-board computers are used to identify prominent and hidden vehicle faults. They allow the car enthusiast to perform repair operations in a timely manner. Thanks to on-board computers, it is possible to significantly save money on diagnostics in car-care centers.

So, you decided to equip your car with such a device. Consider how to install the on-board computer. If specialists do not want to pay money, then you need to install it yourself. Let's move on to the installation process.

  • First we need to remove the negative terminal of the battery by opening the trunk. We go in the salon and remove the knob adjustment stove.
  • Next we need to unscrew the two screws. In the glovebox, we see two black screws, and they need to unscrew, then pull out this box.
  • Now we need to remove the front panel, pulling it towards us.
  • Remove the panel very carefully, as it is possible to break it. Disconnect the wires carefully beforehand.
  • The wires for connecting to the on-board computer are connected to the green wire of the fuel amount sensor.
  • Look, maybe you have a separate connector for the BC. If there is, then there should be no connection problems. But if there is no such thing or you cut it off, you will have to tinker with the wires.
  • In domestic cars there is a white wire data bus, and we will connect it to the connector in the car. How to do this is written in the instructions. Now we can connect the onboard computer.
