Many owners of a Lada Priora, Grant or Kalina 2 are faced with a malfunction in the direction indicators. Based on past experience, they begin to look for the cause of the failure with the relay or fuse, but they cannot find them. Let's look at how the turn signal circuit diagram works and the procedure for troubleshooting.

Emergency signal malfunctions
If the VAZ 2114 emergency light does not work, then troubleshooting should begin with the fuse box. To do this, you need to check and, if necessary, replace with a new one, 10 Amp fuse F2. Simultaneously with checking the fuse, you should inspect and clean the contacts in the mounting socket of the common unit (if they are oxidized, the emergency light may not work even with a working fuse).
The next step in finding a breakdown is to check the presence of voltage at contact X2/5, which is located on the mounting block (this is done using a multimeter and with the emergency button turned on).
The lack of power will indicate a break in the wire that goes from this contact to the alarm button.
If the wiring turns out to be working, then you should check the emergency light bulb and, if it is burnt out, simply replace it with a new one (the new light bulb must be suitable in power - you should not install weaker or more powerful lamps). At the same time, the contacts in the cartridge should also be cleaned.
You can do this:
- fine sandpaper;
- kerosene;
- refined gasoline;
- VD-40.
The turn signal does not turn off automatically
I didn’t post in the thematic forum because... I think the design of the turn signal switch is the same everywhere.
The bottom line is that when turning on the turn, when the steering wheel returns to its original position, the turn signal does not turn off automatically.
Has anyone ever taken the switch apart? What is there that returns it to its original position and what could break there?
It was on the last Opel. steering wheel position sensor. Or the SIM module is driving. but this is on Opel.
IMHO everything is mechanical there. A flag on the “guitar” of the turn signal, a corresponding protrusion on the steering wheel. One of the above is broken. Do you hear clicking noises when turning the steering wheel?
Yes, it’s pure mechanics, of course. I just don’t want to climb in there yet, in case someone has encountered it and knows how it works there. I want to consult
There are no clicks when turning, everything is as usual.
I had this happen.. the spring from the flag came off in the switch =)

what kind of checkbox is this?
If there are no clicks when turning the steering wheel, this is NOT AS USUAL. Usually they do. There is nothing complicated there, the whole difficulty is to remove and install the steering wheel correctly (the wheels are straight), and everything is visible under it. Either the spring has come off, or the flag has broken off - you can take it apart and see what a “flag” is. Don’t delay disassembly, because the broken part (if this is really the case) can cause something else to turn around when the steering wheel is rotated. My signal was closed by a flag, but that was still on Moskvich.

How to avoid liability if the left turn signal does not work
However, such rules only apply when the left (or right) turn signal is not working.
What should you do if your right or left turn signal is faulty and you are pulled over by a police officer after breaking a traffic law? Follow the algorithm of actions outlined below.
First of all, say that the turn signal is broken, you recently found out about it and are heading to a car service center to fix the problem.
- Then indicate that in paragraph 2.3.1 of the traffic rules it is allowed to drive to a service station or parking lot, despite the fact that the car is faulty (with the exception of more serious breakdowns).
- Express your disagreement with the traffic police officer.
- Then the state traffic inspector will be forced to prove that the turn signal is not working.
In all other situations - they forgot to turn on the turn signal, deliberately did not inform other road users about the turn - you should admit your guilt. In the worst case, you will have to pay a fine of 500 rubles. At best, the traffic police officer will give you a warning.
Reasons for failure of turn signals and emergency lights
As you know, the circuit of direction indicators and hazard warning lights is tied, since both functions are performed by the same headlights. If for some reason the hazard lights are working, but the turn signals are not, or neither the turns nor the warning lights are on, this can lead to an emergency situation on the road.
For what reasons did these elements stop working:
- Fuse failure is one of the most common problems. If the car is additionally equipped with a relay that is responsible for the operation of these optical elements, then the problem may lie there. Depending on the car model, the relay may be located separately from the main fuse block; use the diagram to find the failed part.
- Short circuit in the system. Because of this, when turning on the turning lights, the emergency lights turn on or the optics do not respond to the driver’s commands at all. To diagnose the problem, you will need a tester, as well as the skills of an electrician.
- Failure of the lighting source. In other words, the light bulb has burned out.
- Open circuit. This problem is relevant for many car owners of older cars. If the wires are laid in a place where there are moving elements, then over time it will fray and lose its insulation, which will generally lead to damage to the electrical circuit.
- Failure of a button or steering column switch. In this case, it is necessary to carry out more thorough diagnostics of the switch, as well as the connection button.
