The instrument lighting of the VAZ 2114 injector 8 valves does not work

The dashboard lights of the VAZ 2114 do not light up

The dashboard on the VAZ 2114 allows the driver to control engine data, monitor the remaining amount of fuel, his speed, and other data. The panel should be maintained in working condition so that the backlight not working does not cause discomfort, and the sensors show real values.

Bright backlight

But quite often, VAZ 2114 owners discover that the instrument panel lights do not light up. If such a situation occurs, appropriate action should be taken immediately to eliminate it.

If all the lights don't light up

Sometimes on 2114 the dashboard backlight stops turning on completely. Usually, to restore its functionality, you need to change the fuse. In the new type mounting block it is F10 at 7.5 A. The part is green. Its location is shown in the figure below:

Replacing a fusible element, as a rule, does not cause difficulties for car enthusiasts. You can change it yourself. Therefore, when the instrument panel stops lighting, you need to remove the fuse and install a working one. If everything works, then the fault has been identified correctly. If in doubt, the part can be checked with a multimeter. But sometimes the tidy may not light up for other reasons. This:

• Burnt out contact board;
• Broken wiring;
• Oxidation of contacts.

They can be diagnosed using a multimeter and visual inspection. You can usually identify and fix these problems yourself. But in some cases, the help of an auto electrician may be required.

Why the instrument panel does not work

The first thing you need to figure out is why the instrument panel on the VAZ 2114 does not work. If the backlight goes out, there may be several reasons for this:

• The incandescent lamps burned out, the LED lighting groups stopped working;
• The connectors have oxidized;
• The electrical wiring is faulty, there are defects in the circuit;
• The fuse box has stopped working;
• Damage appeared on the common contact board;
• The dimensions system is damaged;
• There is no minus on the body (weight).

Replacing light bulbs with LEDs in the instrument panel

I decided to change the light bulbs in the instrument panel due to the fact that they began to burn out, since an alarm was connected to the dimensions. I decided to buy LED bulbs so I don’t have to climb anymore.

In the store I decided to buy regular white ones; there were red and green ones to choose from. I also bought bases for them, since in my device, and it is from AP. The bulbs are soldered to the bases. If you need to change all the light bulbs, you need 12 pieces, if only for the backlight, then 7... I decided not to save money and change everything.

Removing the dashboard

To replace the light bulbs in the dashboard of the VAZ 2114, it will first have to be dismantled. Without this action, you will not be able to access the problematic device.

Panel disassembly diagram

Therefore, now we’ll figure out how to disassemble the instrument panel on a VAZ 2114:

• Unscrew the three screws, remove the trim and the protrusion from below. It comes out of your car's body bracket;
• Now remove five more screws located on the right console trim;
• Remove the screen; Disconnect the negative terminal from the battery;
• Disconnect the wiring harness connector from the cigarette lighter;
• Remove the handle from the lever;
• The fasteners for the electric fan of the heating system, that is, the stove, also have to be removed;
• Unscrew the steering wheel block bracket fixing bolts;
• Remove LEDs, lamp sockets and decorative inserts on the panel;
• Unscrew the hydraulic corrector illumination lamp. For this you will need a key for 21;
• Now all that remains is to remove the screws at the top and bottom.

Thus, we figured out how to remove the dashboard on your VAZ 2114. Be sure to cover the electrical circuit with something after the measures have been taken to prevent moisture, dust and all kinds of contaminants from getting there.

Proceed to replace the lamps that turned out to be faulty. At the same time, many are interested in how many light bulbs are in the dashboard of the VAZ 2114. There are 13 of them, but only 8 can be replaced. Do not forget to clean the contacts if there are traces of oxidation on them. In some cases, it is not the lamp itself that has to be replaced, but the socket for it.

How to choose lamps

According to current regulations, damage to a vehicle's structure is punishable by a fine or even deprivation of a license. Therefore, only an equivalent replacement of the same lamps used by the manufacturer is considered acceptable. However, traffic police have a more correct attitude towards dashboard lighting. This is due to the absence of danger for drivers of oncoming vehicles.

Most car owners use LED analogues instead of traditional incandescent lamps. This choice is explained by the significant advantages of LED devices compared to traditional lamps:

• long duration;
• lack of heat, which negatively affects plastic parts.
• low power consumption, does not drain the battery;

Attention! The only drawback can be considered the relatively high price, but since the appearance of LED lamps on the shelves, a decrease in their cost has been noted. In addition, the range of LED lamps is large and allows you to choose inexpensive items.

All lamps are selected according to the following parameters:

• cartridge type - 2W2;
• power - 12 W.
• supply voltage - 12 V;

Sometimes you have to change all the devices. When purchasing, you need to know how many light bulbs are in the instrument panel of the VAZ 2114. For a complete replacement, you will need to purchase:

Typically, LEDs are initially installed in the BSC, since it comes as a separate unit. When purchasing replacement lamps, there is no need to buy cartridges; they remain operational longer than the lamps themselves. A total of 8 light bulbs need to be replaced. They are the same; when purchasing, you should be guided by the type of cartridge, supply voltage and power.

Selection of light bulbs

Today the market offers a wide range of lamps that can be used for the dashboard of the VAZ 2114. Among the most well-proven devices, we note a few. Their name and cost are presented in the table.

Replacing the backlight

In analysis
To improve the quality of your dashboard lighting, it is advisable to install new LEDs in place of the old ones. They provide excellent illumination, consume minimal energy, and guarantee a high level of data reading.

1. Buy a set of LED lamps, having previously calculated the number of devices needed for each sensor.
2. After removing the block, install the resistors and lamps in specially designated places on the VAZ 2114 - in the sockets. To dismantle the cartridges, they are carefully unscrewed counterclockwise. New sockets are installed in their place and light bulbs are inserted. Respect the polarity and position the LED heads. They will have to be carefully ground off.
3. Connect the power and check how the new backlight works.
4. Reassemble step by step. Be sure to route the wiring to the board and carefully secure it to it. This way, the backlight components will not interfere with the reassembly process.
5. Make sure the instrument panel arrows are positioned correctly. When trying to quickly complete a job, they often become deformed and bent.
6. The backlight structure is fixed with screws.
7. The power for the LEDs is connected to the power supply for the light bulbs, the arrows are put on and set to zero.
8. Using the on-board computer, check the operation of each sensor and device. If the IDs are functioning correctly, return the instrument panel to its original condition. That is, assemble the entire assembly.

Designation of light bulbs and indicators on the instrument panel of the VAZ 2114

The dashboard, by definition, is designed to contain instruments, indicators and switches that could inform the driver about the current state of various vehicle systems, signal an emergency during the operation of the car or the failure of any units, as well as using buttons and switches control individual equipment or mechanisms.

The designation of icons on the instrument panel of the VAZ 2114 is made in accordance with all requirements and standards that call for the unification of symbols so that they are absolutely clear to every driver. The symbols on the instrument panel of a VAZ 2114 with the latest injection engine are located mainly in the lower part of the instrument cluster:

Indicators VAZ 2114

1 - the icon of the light indicating that the oil level in the engine crankcase has dropped below the minimum level, lights up in red;

2 - this light indicates an insufficient level of washer fluid; it lights up orange when the remainder in the tank is less than one liter;

3 - this icon, lighting up in orange, indicates a decrease in the coolant level in the expansion tank with a cold engine below the permissible level;

4 — warning light icon for unlocked doors, lights up red;

5 — fault indicator for “brake lights” or dimensions;

6 - this is a warning light for a malfunction in the brake system, indicating that the brake pads are worn out;

7 - light bulb icon that indicates unfastened seat belts.

On earlier versions of the car, the designation of the light bulbs on the dashboard of the VAZ 2114 in the lower part is slightly different, when viewed from left to right:

Designation of icons on the instrument panel of the VAZ 2114

• emergency oil pressure icon (18), lights up red when the level drops below the minimum;
• red handbrake indicator light (17), if it is on, it means the brake is not released;
• a warning light with an icon representing a battery (16), which lights up when it is discharged;
• warning light (9), indicating that the brake fluid level in the reservoir has dropped below the minimum level.

In addition, car enthusiasts should know what the lights on the VAZ 2114 instrument panel mean, indicating the performance of the lighting equipment or the condition of the engine:

• in the upper part of the instrument cluster between the speedometer and tachometer there are two green arrows (3 and 4) indicating that the turn signals are on on the left or right;
• Below is a triangular red emergency stop icon (13);
• under the emergency stop sign there is a CHECK ENGINE light (14), which lights up red when any malfunction occurs in the engine automation;
• on the right there is a blue light bulb for high beam (10), which lights up when it is turned on, and a green light bulb (8) for low beam.

Causes of malfunctioning dashboard lighting

The instrument panel on the VAZ 2114 is a whole complex of interacting sensors and equipment. Therefore, it is quite difficult to determine exactly why it does not burn. However, the problem in most cases occurs due to one or more of the following malfunctions:

1. The filaments in the light bulbs burned out or the LED elements were damaged.
2. A deposit of oxides has formed at the contact points of electrical connections.
3. Fuses have blown.
4. Electrical wiring is damaged.
5. The contact board has failed.
6. The “ground” on the body has disappeared (negative charge from the battery).

For those who are familiar with the basics of automotive electrics of the VAZ 2114, it will not be difficult to independently find the cause of the breakdown. To do this, you will need to carry out a series of dismantling works and check the availability of power supply in individual components, armed with a tester or voltmeter.

Why lamps burn out or stop working: causes and consequences

Burnt-out lamps complicate the driver’s control over the car’s instrument readings.
The operating conditions of the backlight are not ideal: shaking, temperature changes, possible power surges in the on-board network, and so on. When driving, you must turn on low beam headlights. Along with it, the instrument lighting also turns on. This can shorten the life of the lamps, and over time, not the entire panel is illuminated evenly.

The main danger of lamps burning out in the instrument cluster is that some of them are control lamps. In this case, you may not know about the failure of individual machine components. And uneven illumination looks ugly.

Solutions

First of all, you need to check the backlight bulb; if it does not work, it needs to be replaced. Also, the reason that the instrument panel does not light up in the VAZ 2114 may be a violation of the integrity of the wiring. She should be called. A damaged fuse and electrical circuit, as a rule, cannot be repaired - they simply need to be replaced. Let's look at quick ways to solve these problems.

One or more light bulbs do not light up

One of the most common reasons why the instrument panel lighting on a VAZ 2114 stopped working is burnt out light bulbs. The electrical circuit in this model is designed in such a way that if one light source fails, all of them stop working. To determine exactly what is broken, you will need to ring the entire system using a tester. Another reason for the lack of lighting may be the independent installation of LEDs instead of standard incandescent lamps. In this case, an error is often made in the distribution of power or the electrical parameters of the led elements are calculated incorrectly.

Main conclusions

If the instrument panel backlight on a VAZ 2114 car does not light up, most likely the light bulb has burned out or the LEDs have failed. However, there are several other possible causes for this problem:

1. The wiring is damaged.
2. Oxides have formed at the contact points.
3. The safety side has failed.
4. The electrical circuit burned out.

To establish the exact reason why the backlight does not light, you must, following the instructions, carefully disassemble the instrument panel and sequentially ring the entire circuit using a tester. The found faulty element, depending on the degree of damage, must be repaired or replaced with a new one.

Troubleshooting steps

To diagnose and repair the backlight system for the instrument panel on a VAZ 2114, you will need a pair of wrenches, sizes 8 and 21, and a set of screwdrivers. The general procedure for dismantling and adjustment work boils down to the following steps:

1. Remove the trim by first unscrewing the three fastening screws and removing the protrusion from the body part bracket.
2. Remove the five mounting screws from the right side of the console and remove the screen.
3. Disconnect the terminal with the battery suitable for the negative power source, as well as the block with the bundle of wires from the cigarette lighter system.
4. The handle of the lever mechanism is removed.
5. The stove ventilation system clamp is dismantled.
6. The screws securing the steering column brackets are removed.
7. The sockets are unscrewed, the light guide and the decorative panel insert are removed.
8. The light bulb for illuminating the hydraulic corrector is removed using a 21 key.
9. Finally, the screws that secure the top and bottom of the instrument panel itself are unscrewed so that it can be removed.

Once the instrument panel is removed, you can begin to find the reason why the backlight is not on. First of all, it is customary to check the lamps on the VAZ 2114. If they are working properly or after replacing the damaged unit the system still does not work, you should clean all contacts from the oxide film. To speed up the process, it is better to use special mixtures such as VD-40.

Upon completion of all these manipulations, it is necessary to perform a wiring test to detect a break. For this you will need a multivoltmeter or tester. If all the checked elements are in working order, but the backlight does not light, the safety module is to blame. It needs to be replaced with a unit with similar technical characteristics (and preferably from the same manufacturer).
