DRLs don't light up on the grant

In short, I'll take it under warranty, let them rack their brains.

That's right, then write down what the trouble was. Good luck

I went today under warranty and attended the inspection. In short, the problem was in the lamps themselves (When you start shaking them, they light up), it turns out they shook the lamps for me at TO-3 and said that there was a bad contact.

yes, they are fooling our brother ((

Are all the previous ones intact?

Is there an abnormal alarm?

Are all the previous ones intact?

If the front burnt out, then both would stop burning. (I tried)

As I understand it, you didn’t ask the reason at the maintenance? And they didn’t say it themselves either?

At first I didn’t ask, but the next day when the light stopped burning I asked. He told me that the contact was bad in the connector itself. (Although I tried the same thing myself, it didn’t help me.)

Damn, masters)) So take it back to them - let them establish contact)) It’s good if it’s a trifle, but if there’s something wrong with the wiring, then it’s fraught with trouble in the future. I read somewhere about problems with DRLs when the signal was connected incorrectly, the lamps burned out there too... Right now I can’t find the source. I read it on the Lada Granta Club, it seems. But you yourself don’t associate any of your recent manipulations? Maybe he changed something?

When you turn on the car, the DRLs come on and two lights come on. When the headlights are turned on, the right DRL lamp does not light up, and also when the daytime running lights are turned on, all the lamps are on, but the right one is not.

The fuses are fine. Also, in the parking mode, the right brake light does not light up, although when the brake is pressed, it lights up. What could be the problem?

Change the light bulbs. The lamps have two filaments - P21/4W and W21/5W.

So, flies separately, cutlets in the other direction! DRLs are DRLs, dimensions are dimensions. DRL - thick filament in the lamp, 21 watts, size - thin, 5 watts. In this case, the lamp burned out. And it’s not a fact that the new one is good, the lamps themselves burn out once a month, then one, then another.

Got distracted. It would be a good idea to check for DRL voltage on the cartridge. If indeed the new lamp is working. Or replace the left lamp with the right one.

Further. Daylight. I don't understand this term. No, in general it’s clear that there are fluorescent lamps in lamps, but I don’t know how to apply this to a car.

Further. Right stop. Here, as I understand it, this is a “luxury” package; I won’t offer anything other than diagnostics of the body electronics unit.

If you are sure that the fuses are all right (although there is a weak contact on them), then there remains a weak contact on the lamps or the absence of ground. Electrics is the science of contacts. The fuses are intact, the lamps are intact, only the contacts remain (they are weak or completely absent). Multimeter in hand and ring.

Now we will try to figure out why the low beams on a Lada Granta may not turn on.

Russian requirements for DRLs

The characteristics of DRLs and the requirements for their installation are determined by Russian GOSTs 41.87-99 and 41.48-2004, taking into account the EEC Rules.

DRL parameters:
emitters must be at least 40 cm in area;
White color;
the light source is not regulated, i.e. any lamps are allowed: incandescent, gas-discharge, LED;
luminous intensity – 400-800 cd.

Required DRL operating mode:
automatically turn on simultaneously with the ignition;
go out when the headlights are turned on, except when the headlights flash to give warning signals.

Installation/placement of DRL:
at a height of no lower than 25 and no higher than 150 cm above the road surface;
no more than 40 cm from the edge of the vehicle;
between the inner edges of a pair of DRLs - at least 60 cm.

In general, if you install DRLs on a car, then only certified devices - their parameters comply with Russian GOSTs. During installation, you must comply with all requirements for their placement. Then running lights will be useful and safe, and, in addition, it will be possible to avoid fines for incorrect use of lighting devices.

Main reasons

Consider in detail the most basic reasons for such a breakdown.

Fuses blown

The fuses in the mounting block have burned out (F12 - right side, F13 - left side). Their rating is 7.5A.

F12 - left headlight, F13 - right headlight

The fuses in the photo are marked with an arrow. (top - left headlight, bottom - right headlight)

In this case, the voltage regulator may be faulty. As a result, a power surge occurred and both fuses were blown. It is necessary to check the voltage of the electrical circuit under load.

If the problem persists after replacing the fuses, it is better to contact an automotive electrician.

If you are on the road at the time of a breakdown, you can install a “bug” instead of fuses.

Carefully insert a piece of wire into the fuse connectors, preferably one, the left fuse. In this case, do not put the cover of the mounting block back on, as you will have to conduct a visual inspection; the wire may begin to heat up.

Important. We do not recommend using bugs or higher rated ceramic fuses. Try not to overload the electrical circuits, for example, when installing a cigarette lighter splitter, route the power cable directly to the battery through an additional fuse.

Low beam bulbs burnt out

“Right low beam” burned out

The low beam bulbs burned out, both of them at once, either a coincidence, or a short one, or the low beams were not turned on at idle. At high speeds, the current is greater, so both can burn out at once. The voltage regulator may also be faulty.

The low beam contact relay is broken

Location of the contact relay in the mounting block

The low beam may not turn on due to a broken contact relay. This breakdown is a very common reason. Due to the design of the relay and its low cost, the contact group may become stuck.

Open the fuse box (mounting block).
We take out the relay number K9.
It is advisable to take a known good relay for a test drive. Or you can lightly tap the old relay with a key or coin.
Reinsert the contact relay.
Checking the low beam operation.

Light control module failure

Light control module on Grant

This fault should be checked last. The cost of a new part is about 900 rubles, so the easiest way is to replace the module with a known good one, for example, take it from another car.

Grant providers recommend installing the MUS from a luxury model.

If your high beams also do not work, then check whether voltage is coming to the MUS.

Fuse box

The fuse box in Grant is located to the left of the steering column, near the light switches. To remove the cover and access the fuses and relays, pull the top left side of the cover towards you. It’s made conveniently, everything is at hand and you don’t have to climb anywhere when getting up from the driver’s seat. Maybe this is a hint that they will often have to be changed, or maybe just convenience - the developers know better.

F1 (15 A) - engine control unit, injectors, ignition coil, cooling fan relay, short circuit 2x2.

If all else fails

If none of the above helped you, then most likely there is a break in the circuit somewhere. It could appear as a result of:

mechanical impact (mice, rodents);
time (the wiring has deteriorated);
overheating of the wire and damage to its insulation.

This is a job for a professional electrician. The algorithm of actions is as follows.

We look at the voltage on the fuses. There should be 12 volts constantly.
We look at the voltage on one of the 33 contact chips. We need one with gray-black and gray wires in the corner part. These are the wires for the low beam headlights.
We look at the voltage at the headlight terminals.

If there is voltage everywhere, then the problem is an open circuit between the mounting block and the headlight.

Lada Granta running lights do not work

The question is that the DRL light does not work (does not light up), but when the headlights are turned on, it lights up. Can someone tell me the reason?

Hello! Who can tell me that the brake system warning light is constantly blinking, the fluid level sensor is normal, off, the parking sensor is working, I checked with a jumper and it does not go out, Lada Granta car, thanks in advance!

I have the same problem... I changed the lamp and three days later it burned out again (you need to look for diodes that are better than 30 rubles each.

The light bulb is definitely burnt out, it is a two-filament light bulb. I had it too.

both DRLs are on the same fuse F23 10 Amp. So anyway, it's a light bulb. And no offense, of course, but starting a discussion about the light bulb, it seems to me, is overkill.

This is one filament that has burned out in the lamp!

If the fuse had burned out, then the left tail light, the left DRL and the front light would not have lit up (there is one fuse per side)… it’s just the thread that’s burned out

there is a two-contact lamp. There are two threads, maybe one is dead. On the contrary, the marker did not light up, but the DRL did light up. I changed the fuse and it worked)

Do you remember the fuse number?

left clearance F10.DRL F 23

There is a two-filament lamp, one DRL filament burned out

I support, one filament has burned out, you can check it visually, change the lamp, or immediately install diodes and bend the contacts, then the fire will burn out and nothing will burn out :)

Which contacts need to be bent?

I support, one filament has burned out, you can check it visually, change the lamp, or immediately install diodes and bend the contacts, then the fire will burn out and nothing will burn out :)

I inserted an LED lamp, the fuse burned out (right row, 4th from top to bottom). I changed the fuse, but the problem remained! The right side and front and rear markers do not light up, the DRL on the right also does not light up. The fuse is intact!

Now we will try to figure out why the low beams on a Lada Granta may not turn on.

Features of choice

The necessary increase in brightness or service life of light bulbs can only be achieved by replacing existing lights. Car enthusiasts often replace the halogen lighting sources installed in Lada with LED ones. As a rule, even a person without experience in replacing lamps can cope with this task.

However, you should know a few nuances. Simply placing a new diode in the right place is not enough - the process has its own characteristics.

Main reasons

Consider in detail the most basic reasons for such a breakdown.

Fuses blown

The fuses in the mounting block have burned out (F12 - right side, F13 - left side). Their rating is 7.5A.

F12 - left headlight, F13 - right headlight

A little background

One sunny day you got bored and decided to do some easy tuning of your Lada Vesta, which, as you know, starts with the light bulbs.

It's no secret that standard DRL lamps look somewhat depressing, with a yellowish tint. It’s especially sad that they decided to make LED running lights on the X-ray’s sibling.

So, you bought Chinese white LED bulbs with huge declared lumens to embellish the appearance of your pet. You start dismantling the old ones, install new lamps and, in anticipation of white rays of light, start the car and get... no light.

After slight bewilderment, you try to return everything to its original state - install the incandescent lamps back in place and again check the operation of the running lights. But a miracle does not happen, the light is still missing and you begin to sort through ideas, look for the reason for what happened. Usually the first thought that comes to a car owner’s mind is “The fuse has blown!” You open the fuse table, find the required F39 and are perplexed - it is intact.

If all else fails

If none of the above helped you, then most likely there is a break in the circuit somewhere. It could appear as a result of:

mechanical impact (mice, rodents);
time (the wiring has deteriorated);
overheating of the wire and damage to its insulation.

We look at the voltage at the headlight terminals.

If there is voltage everywhere, then the problem is an open circuit between the mounting block and the headlight.

Replacement instructions

So, if you want to achieve a better glow and increase the service life of your optics, just change the lighting sources in it. As practice shows, the most popular option in this regard is to replace traditional halogen lamps with diode light sources. But before you begin this process, you need to understand that simply installing a diode instead of a halogen will not be enough.

After all, this process has certain features:

Typically, for installation it is necessary to tear off the base previously installed on the diode element in order to transfer it to the required hole.
Replacing Lada Granta DRL lamps also involves checking the polarity of the lighting sources in order to maintain the functionality of the safety element. If you do not do this, the fuse will fail in any case, thus de-energizing the safe operation of the on-board network.

Car daytime running lights

The replacement procedure is as follows:

First, you need to turn off the ignition, open the hood of the car and disconnect the terminals from the battery. This will allow you to turn off the device and ensure further safe operation when the power supply is de-energized.
Let's start the replacement with the light sources in the right lamp. To do this, pull out the cartridge; to do this, you need to rotate it counterclockwise.
Then the failed lighting source must be removed from its seat; to do this, simply pull it towards you.
After completing these steps, make sure that the antennae on the removed bulb correspond to the location of the contacts on the new one. The antennae themselves should fit into the mounts on the optics without any problems. Install the new lighting element at a 45 degree angle.
Next, the lamps in the left headlamp are replaced. Here the procedure will be slightly different, since it has its own characteristics, in particular, it will be more difficult to reach the light bulb. Before changing devices, it is necessary to dismantle the air filter unit; to do this, disconnect all fasteners and clamps, as well as pipes. It will also be necessary to unscrew the pipe through which the coolant passes. The block itself is supported by three special clamps; they must be removed.
After completing these steps, you will need to repeat all the replacement steps described above. Further assembly is carried out in reverse order. Now all you have to do is connect the battery and check the functionality of the optics.

Price issue

The cost of a set of lamps or the daytime running lights themselves can vary greatly depending on the manufacturer and place of purchase. Below are the average prices for headlights, as well as lighting sources that can be purchased on the Russian market.

1. Set of DRL SOV LED DRL (price - about 2 thousand rubles)2. Set of light bulbs 1156 PY21W BAU15S 42 LED 2835 (price - about 2600 rubles)3. Set of flexible DRL-110 with rotation (price - approximately 1,500 rubles)

Video “Checking and repairing the VAZ 2107 signal”

This video demonstrates how to diagnose and repair the horn on a VAZ 2107 (the author of the video is DamirBikmetov).

Two types of sound signals can be installed on a car: a double signal, consisting of two signals of different tones and mounted on a bracket near the radiator in the engine compartment, or a single signal, which is also mounted on a bracket between the radiator and the radiator grille. Removing the sound signal of the VAZ 2107 is carried out in the event of its failure for subsequent replacement. The signals cannot be repaired and if something happens they are simply replaced with new ones.

The signals are switched on using an auxiliary relay and a switch that closes the negative terminals to vehicle ground. During operation, the sound signal membrane gradually loses its elasticity and the tonality has to be adjusted. If the car has a double signal, then they must be adjusted one by one, and the help of an assistant will also be required.

The procedure for adjusting the sound signal is as follows:

The two signals are adjusted separately, which means we disconnect one sound from the power supply.
We put the assistant in the car so that he turns on the signal.
Using a flat-head screwdriver, rotate the screw located on the signal housing in both directions and achieve optimal sound.
We do the same with the second one.

If your car has a single horn, you will have to remove the radiator grille. The adjustment work is identical.

If you need to replace the sound signal, you must:

We disconnect the supply wires, having previously marked them with a marker so as not to confuse them during further connections.
Using a thirteen-size wrench, unscrew the nut securing the signals to the bracket and remove it.

At this point, work on removing and adjusting the VAZ 2107 sound signal is completed. Installation is carried out in the reverse order of removal.

From a road safety perspective, the horn plays an important role in preventing road accidents. On a VAZ-2107 car, depending on the modification, two sound signals of different tones can be installed behind the radiator of the cooling system, or one sound signal, which will be installed behind the front radiator trim.

To put it into operation, a horn button is installed on the steering wheel, and a fuse F7 (20A) and a horn relay RS - 528 are installed in the mounting block. But on some VAZ-2107 cars this relay will not be installed, and in its place there will simply be stand jumper.

If there is no sound signal, troubleshooting should begin by checking the fuse. You need to look not only whether it has burned out or not, but also the condition of its contacts. The horn relay, if your car has one, can be checked quite simply; when you press the horn button, it should click; if the click is not heard, you will have to replace it.

The sound signals themselves can be checked without removing them from the installation site. To do this, disconnect the wires going to it and connect the horn directly to the battery. If there is no signal, a possible malfunction may be burning of the contacts located inside the audio signal housing or a violation of its adjustment. You can adjust the tone by turning the adjusting screw located at the back of the horn housing and gently turning it in one direction or the other.

Another reason for the signal not working may be the power button itself. You will have to remove it and check the condition of the contacts. Malfunctions that arise in the operation of the sound signal on a VAZ-2107 car can easily be corrected by the driver himself.

Lamps for increased visual comfort

Although the standard lamps with a yellowish dull tint in the running light system may still remain in good working order, many Lada Granta owners strive to immediately replace them with halogen ones with bright white light. The reason for this is to increase visual comfort. It is also noted that this can emphasize the exterior profile of the car.

Comparison of DRL lamps - the photo shows a standard (installed from the manufacturer) and a luxury lamp

Halogen bulbs from the following manufacturers are very popular among car enthusiasts:

Philips.
Lighthouse.
OSRAM.
IPF.
General Electric and some others.

Like other modifications, halogen lamps for DRLs still have the same characteristic number of disadvantages. First of all, this is increased heating and, because of this, the shelf life decreases with increasing power. For this reason, when choosing such sources for the Lada Granata, you should take into account that they can be produced in two versions:

Light Day.

The first option meets all legal requirements, but at the same time has average durability. The second one is more economical and, although it does not shine as brightly, it lasts longer.
