Advice 1: How to remove the on-Board computer VAZ

In recent years, many equip its vehicles are equipped with regular on-Board computers. They allow you to monitor the machine's systems online. But not all owners like this gadget, imposed by AvtoVAZ. This computer can be removed without a visit to the service station.
How to remove the on-Board computer VAZ
You will need
  • - screwdrivers;
  • - wrench set;
  • - the instruction manual for your car.
Instruction
1
Read the instruction manual for your car. It must be indicated detailed instructions for dismantling the onboard computer and its operation. If you have no manual, then visit the forum dedicated to your model of VAZ. There you can find detailed information and testimonials from those who have removed on-Board computer.
2
Check about the warranty with an employee of the salon where you bought your car. Some dealers are depriving buyers of guarantees for independent removal of pre-installed equipment.
3
On cars VAZ of the tenth family and the Priors for removing computer, you must first disassemble the radio. To do this, open the hood and remove the negative terminal from the battery. This will disconnect the onboard power supply system and will eliminate the possibility of short circuit.
4
Remove the outer panel of the radio by pressing the open button. At the end of the radio there are four holes. Paste the special keys and click on them until they stop.
5
Pull the body of the radio itself. Completely pull out the entire radio. Gently detach the back side of all pads wires. Insert your hand into the hole, in which stood a radio, find the back of the unit on-Board computer mounts, open them carefully and hit on the body itself.
6
Remove the Board computer from its slot, unplug from the back side of all the wires. If you do not plan the installation of the new border, then interlock all the wiring for connecting plastic harness, and the hole close standard plastic plug.
7
Remove all additional devices that were connected to the onboard computer. For example, the antenna and popmonitor. Connect the unit and install it on a regular place in the reverse order.

Advice 2: How to put an onboard computer on WHA

Onboard computer – very convenient and useful device for cars VAZ. Installing it in the car, you will get many useful and convenient features that not only improve interior comfort, but will allow in all conditions to choose the optimum driving mode.
How to put an onboard computer on WHA
You will need
  • - on-Board computer;
  • cable-wire;
  • adapter
Instruction
1
To install the computerand for cars Lada Kalina and Priora remove the radio from its installation space. Remove the cover marked with OPEN. In the rear wall of the compartment lid, drill a round hole with a diameter of 17 mm, or a rectangular size 17h10 mm cable. When drilling, be very careful not to damage any extraneous wires.
2
Pass the cable of the onboard computerand through the resulting hole. Remove the screws on the compartment for small items. In a niche this compartment to install the adapter connection, pull the ribbon cable and secure the adapter by turning screws.
3
Connector signal Flex cable plug into the connector located on the DLC. Install all previously removed parts and secure them with the regular mount. Put a removable panel on-Board computer.
4
On front-wheel drive cars of the family Lada Samara and Lada Samara 2 install the onboard computer instead of the plugs on the console of the car. After removing the cover, locate in the niche of a standard 9-pin connector to connect the computers.
5
Brown wire connect to socket M DLC (for machines € 2) or to the socket 7 (for Euro 3 cars). The other end of the brown wire will turn on in the socket 2 pads on-Board computer. The DLC located in the lower part of the instrument panel near the floor. The blue wire plug in the socket 4 PC. Internal temperature sensor output under the hood.
6
On cars VAZ-2108-21099 additionally, perform the following connections. The white wire circuit fuel level sensor connect to 11-th contact pads of the instrument cluster or the wire is pink with a red stripe. Orange wire to 2nd contact pads of the ECU (under the trim near the driver's left foot). Pink wire – 3rd contact of the same pad.
7
On cars VAZ-2110-2112 install the onboard computer instead of hours or dashboard. to do this, remove your watch and guide the installation process by analogy with paragraphs 4 and 5. Temperature sensor install in the front bumper so that it was protected from dirt, water, snow and air flow. Secure with PVC tape.
8
On cars VAZ of issue until 2001, often missing the wire from the fuel level sensor. In this situation, connect the 8th pin of the connector computerand wire pink 10-th contact pads of the red cluster.
9
For all types of car and computers: yellow, red and black wires are used to power the onboard computer. Yellow plug to the grey wire of the ignition switch. Red – to the brown wire of the castle or to the positive terminal of the battery. Black ground wire – to car body or to the 6-th contact pads of the red cluster.

Advice 3: How to remove catalyst from the WHA

The catalytic Converter effectively purifies automobile exhaust gases. Harmful hydrocarbons, carbon monoxide and nitrogen are transformed into non-toxic compounds – water vapour, carbon dioxide and nitrogen. Sometimes catalysts are deteriorating and require replacement or removal. It's easy to do.
How to remove catalyst from the WHA
You will need
  • Wrenches, pliers, lift or pit, new catalytic Converter, electronic emulator of a catalyst, a heat-resistant tube.
Instruction
1
Determine that the catalyst has deteriorated. It is possible to hear, to smell, to see. Broken ceramic rattles in a metal enclosure like a rattle when the car goes over a rough road. Faulty exhaust gases in the catalyst become hydrogen sulfide smell. Their color also varies from almost transparent to black or grey. When driving the engine is warmed up with labour gaining more than 3 thousand revolutions.
2
Raise the car VAZ on the lift or drive it on the overpass. Or remove the catalytic Converter over a garage pit.
3
The stainless steel inside which is placed the catalyst built into the system just behind the exhaust manifold of the engine. Unscrew two nuts of fastening of a pipe of the resonator to the catalytic Converter. Remove the spring washer. Remove the bolts.
4
Unscrew the two bolts securing the catalytic Converter to exhaust front pipe. Remove the bolts together with the springs, be sure to hold the catalyst with your hand so that it does not fall. Ceramic catalyst fragile and collapses from shock, ingress of water on a heated body, due to poor quality fuel problems with my engine, and much more. For example, riding around town with short runs and frequent starts of the engine it clogs up the honeycomb fuel and soot. And on high-speed motorways catalytic Converter is overheating.
5
Remove the catalyst from under the car. Purchase a new catalytic Converter and install it in place of the exhaust in the reverse order of removal. Often the high cost of the catalyst becomes an obstacle for his replacement.
6
The old catalyst will split, shake the filling to the tank became empty, weld metal and install back. Or is Converter will Waite a piece of heat resistant pipe of suitable size. And for the correct operation of the lambda probe (oxygen sensor) install the electronic emulator of the catalyst (hornblende), which will simulate the presence of intact devices.
Note
The content of harmful substances at the exit of your vehicle will increase dramatically. Three-way catalytic Converter is made of special ceramic or metal monolith with a large number of cells, resembling a honeycomb. A rough surface increases the contact SOT deposited on the entire surface equal to the size of a football field, a thin catalytic layer of platinum, palladium and rhodium, which weigh only 2-3 g.
Without this protection, the car is much less environmentally friendly. This fact may affect receiving pass technical inspection of the vehicle.
