VAZ 21214 Niva injector fuses with description

Where are the fuse and relay boxes located?

The electrical equipment system, electrical wiring and arrangement of safety blocks on the Niva 21214 and the modern Chevrolet Niva VAZ 2131 are identical. The electrical circuit of these machines has a main mounting block installed under the lower edge of the instrument panel casing in the area of ​​the driver's left foot. An additional one is located under the main block.

A little to the left and below there is another additional block, in which inserts are installed that are responsible for the operation of the components of the fuel injection system. In addition to the fuses, there is a separate relay for controlling the wiper operation parameters and a set of relays for the engine control system.

When installing an injection engine on a car with an old wiring diagram, the designers had to install additional switching boxes.

One of these blocks is located on the left side of the body near the main fuse box. Since the unit is installed in close proximity to the driver’s left foot, it is covered with a special protective plastic casing. The casing is fixed with two self-tapping screws for a Phillips screwdriver. The block itself contains a diagnostic connector and four fuses responsible for the operation of the engine and cooling system.

The relay responsible for turning on the engine starter can be installed separately in the engine compartment or next to the relay block. When installed under the hood, it is mounted on the compartment shield next to the brake fluid reservoir.

Fuses Niva 2121

If any equipment in a Niva 2121 car fails, first of all, it is worth checking the integrity of the safety unit. This procedure is not complicated, even an inexperienced car enthusiast can do it, so there is no need to go to a service station the first time such a situation occurs.

Replacing the block will not be cheap, but in order to do it yourself, you just need to find its location. Motorists often notice that fuses sometimes fall out of their mounts. In this case, you should replace the failed or unreliable panel with a new one in which these elements are installed in a more reliable manner. For the convenience of drivers, Niva manufacturers have placed fuses in an easily accessible place.

Description of the fuses in the upper main section of the VAZ 212214 Niva injector.

Overview of the fuses of the small additional block located under the main one.

On Niva Urban 4x4 the fuse ratings have been slightly changed. The changed positions are listed below, the remaining chains and denominations remain the same.

Location and electrical diagram

The fuse block (hereinafter referred to as the fuse block), unlike traditional models of the domestic automobile industry, is located in the vehicle interior. In particular, it is located on the driver's side under the steering wheel. If any electrical circuit element in a car stops working (lamps, interior lights, heater, power windows), then car owners first check the power supply elements. As a rule, the problem is resolved by replacing the fuse.

What does the power supply circuit itself look like? This question may be of interest to Niva owners. Below we will look at the electrical circuit of the unit with a description of all the components responsible for the operation of certain devices in the car.

Power supply circuit for Niva

In accordance with the diagram, we will consider the meaning of the BP elements. This electrical circuit is universal for all Niva cars.

• heater fan;
• for the functioning of headlights and wiper motors; cleaning them;
• for heated rear window;
• for the work of the wipers and glass washer.

• operation of reversing lamps;
• turning on the turn signal lamps;
• turning on the windshield wiper motor;
• functioning of the carburetor damper lamps, engine fluid pressure, hand brake, brake fluid level;
• functioning of the engine temperature sensor;
• operability of the gasoline level sensor in the tank.

It should also be noted that in VAZ 21214 injector cars there is another power supply unit with injection system components. It is located separately from the main power supply on the left side under the steering wheel.

The diagram of the block with the relay, which is located slightly deep in the instrument panel and is responsible for lighting the car, is shown in the photo.

The purpose of the relay in the block (from left to right) is given in the table.

Fuse arrangement in a Niva 21214 car

In Niva 21214, the fuse device has a rather non-standard appearance. There is a spare one under the main fuse box, which takes over its role if the main one breaks down. Also, this car has a slightly changed role of fuses in the chain of operation, namely in their purpose. The table shows several similar examples of fuses with descriptions.

For a more detailed study, you should familiarize yourself with a more structured diagram.

This car also has a second unit, which is located above the gas pedal and includes 4 relays responsible for: interior light, proper operation of the rear lights, rear window heating switch, wipers, high and low beam.

Replacing the block

In case of burnout or mechanical damage, it is necessary to repair the unit by replacing its components or the entire assembly.

To replace the main unit, follow these steps:

1. Disconnect the battery from the on-board network.
2. Remove the box cover and unscrew the two 8 mm nuts securing the block. Then you need to pull the box towards you and remove it from the fastening studs.
3. Write down the markings and position of the wires on the old unit.
4. Disconnect the cables from the plugs of the old unit and connect them in the same sequence on the new one.
5. Check fuse ratings and wire installation.
6. Secure the replaced block with nuts.
7. Connect power to the on-board network and check the functionality of the circuits.

The photo shows some stages of dismantling the block.

Other fuse or relay blocks on the VAZ 21214 are replaced in the same way.

Replacement

In the event of a breakdown, the fuses must be replaced in time to avoid serious problems with important components of the car in the future. The replacement process is quite simple. To do this, you simply need to remove the blown fuse and replace it with a new one.

Thus, further proper operation of the circuit for which he is responsible will be established. A very important nuance is the full compliance of the fuses (blown and new) regarding their markings and the output voltage. Otherwise, if this aspect is not taken into account, any of the elements included in the circuit that this fuse protects may burn out.

As a result, it must be said that the fuse is one of the most important parts in any car and Niva-21214 is no exception. In this regard, it is recommended to constantly monitor the condition of the mounting block and fuses. After all, if their work proceeds without any failures, then the risk of any serious electrical malfunction is reduced to almost a minimum. Thus, the key to a successful motorist is careful care of his car, and, of course, timely repair of all its components, including fuses.

Replacing fuses

If any electrical circuit in the vehicle fails, the condition of the fuse must be checked.

If it is necessary to replace parts, it should be taken into account that the VAZ 21214 fuses on the Niva injector belong to two different types:

• in the main block there are cylindrical inserts (inherited from the Zhiguli);
• and in the injection system blocks - modern, knife type.

Therefore, when you go on a trip, you need to take with you spare inserts of different types.

If, for example, a cigarette lighter fails on the road, you must:

1. Turn off the ignition.
2. Open the cover of the additional unit.
3. Visually check the condition of the PR14 16 ampere fuse, which is responsible for the cigarette lighter circuit.
4. Remove the burnt insert with your fingers and replace it with a spare one taken from the reserve socket PR15. It is prohibited to use homemade inserts, as they are not able to protect the circuit from overloads. The consequence of this may be overheating of the elements and fire.
5. Check the functionality of the circuit. If the insert immediately burns out again, then the reason lies in damage to the wiring, which must be carefully checked.

The remaining fuses and relays on the VAZ 21214 are changed using a similar scheme.

Types of fuses

Over the entire period of its existence, this segment of car elements has changed more than one type. The most common ones are:

Flat fuses are considered a relatively new type. They are used in almost all new cars. They became widespread due to their increased level of reliability and relatively low cost.

The next item will be ceramic fuses, which used to be very popular, but have lost their position due to low efficiency.

The oldest of all types of fuses are glass. They are small cones made of glass. This type of fuses is practically not used today due to the low level of reliability.

These are the most common types of fuses, however, there are others, but less popular.

Location of fuse and relay blocks Niva 4x4

The main part of the fuses are located in the Niva's interior under the panel to the left of the steering column. Total 4 blocks:

1 – engine control system fuse block; 2 – windshield wiper relay; 3 – fuse blocks; 4 – engine control system relay block.

The fourth relay block is located above the gas pedal.

Why does a fuse or light relay or any other constantly blow out? Before replacing it with a similar one, you must first find and eliminate the cause of its burnout. This could be a short circuit, incorrectly selected rated current, etc. Use electrical circuit diagrams to troubleshoot problems. Questions on this topic can be asked on the forum.

How to replace the fuse box on a VAZ-2121 Niva?

The fuse box on the Niva protects the electrical connection circuit from short circuits. That is, if there is an excess of voltage that is outside the norm, the fuse takes the blow. It burns out, but the car's electronics continue to work. Thus, if the car’s heater, lights, window lifts or other electrical circuit elements stop working, you should check the fuses.

Where is the fuse box in Niva

The fuse box on the Niva is located in the same place as most other fuses and relays - in the mounting block of the car's interior, which is located on the driver's side under the steering wheel. To get it out, you need to unscrew two screws with a screwdriver, and then, pressing the top edge of the cover, disconnect it from the dashboard. After this, moving the cover up, you should remove its pins from the rubber bushings and remove the part. When the cover is in your hands you will see the fuse box.

Interesting fact! The first production car, the VAZ-2121, better known as the Niva, rolled off the production line in 1977.

Car fuse box diagram

Important! In injection Niva cars there is another power supply for the injection system, located on the left side under the steering wheel. It is responsible for the operation of the cooling fans, electric fuel pump, control unit, as well as the injection system relay.

Thus, the fuse block is responsible for the operation of all important Niva relays. For normal operation of the car's electronics, you should regularly check the fuses and promptly replace those that are faulty.

What to do if the fuse does not work, how to determine damage

If the fuse stops working, you need to diagnose the elements in the block itself and determine the malfunction. To do this, read the instructions for the car. According to the map, you can find out exactly where the fuse that is responsible for the electrical device you need is located. After this, it should be diagnosed. This can be done visually or using a multimeter. If the wire inside the fuse is broken or it is charred, it should be replaced.

The multimeter will also indicate a faulty fuse. To do this, check the voltage at the terminals. If the values ​​are zero, the fuse is damaged and requires replacement.

Interesting! The cost of the first Niva vehicles was 9,000 rubles, which was not much inferior to the price of the popular and representative Volga.

How to remove and replace the fuse box on a Niva

To replace the fuse box on a Niva, you will need a new block and an 8 mm socket wrench. The removal and replacement process itself is quite simple, and all you have to do is perform a series of sequential steps:

1. Disconnect the battery.

2. Using a wrench, remove the nuts that hold the block in place.

3. Remove the fuse box.

4. Disconnect the wires from the old unit and insert them one by one into the new one.

5. Test the operation of the new unit by turning on the battery. At this point the replacement process can be considered complete.

Important! The battery must be disconnected without fail, since this action can protect you from electric shock.
