For the high-quality functioning of all vehicle systems, it is necessary to ensure correct and reliable control over a number of basic parameters. This is the instrument panel on the Lada Grant. It clearly and timely informs the driver about the operating status of all components of the machine, the speed of movement, and the equipment currently turned on.
Lada Granta - icons on the instrument panel
When buying a car, maximum attention is paid to this detail of the car’s interior. Proper placement of all elements indicates that all the needs and position of the driver have been taken into account.
Designation of Lada Granta tidy icons
The following is a description and explanation of the icons on the standard Granta tidy.
| Number in order | What does it mean |
| 2 | Fault light in the internal combustion engine system. |
| 3/9 | Left and right turn signal. |
| 4 | Indication of drop in engine oil pressure. |
| 5 | ABS system fault indicator. |
| 6 | Lights up when the immobilizer is turned on. |
| 7 | The cooling system is overheating. |

Exclamation mark on Granta's dashboard is on
The symbol is presented in the only indicator indicating a malfunction in the motor electrics. The lamp lights up when the ignition is turned on and goes out after the engine starts.
When an element blinks continuously or is constantly on, this indicates a breakdown. It is recommended to immediately go to a service station and have the defect repaired.
Steering wheel icon on the Granta dashboard
The pointer is responsible for indicating the operation of the power steering module. If the signal is constantly on, there is a problem with the power steering device. The steering may become “wobbly”.
The engine icon on the Grants panel came on
A yellow “check” on the dashboard indicates a malfunction in the motor. If the light comes on, immediately slow down and head to the nearest service center to find the problem and repair it.
Where is the engine temperature on the Grants panel
On the newest versions of the tidy, the indicator is displayed on the BC display. The first generation panels were not equipped with such a meter and only had an engine overheating lamp.
The easiest way to display the internal combustion engine temperature on the dashboard is to install a separate meter on a spare socket in the console. Due to the fact that the designs of non-standard devices can vary significantly, they should be installed according to the manufacturer's instructions.
The oil is burning on the Granta tidy and beeping: reasons
The car's oiler can only indicate problems inside the crankcase compartment. There is a drop in lubricant pressure here, which can cause a leak or pump failure.
Immobilizer icon on the Grants panel
All devices have this symbol. The light indicates that the device is turned on. In this position, it will not be possible to start the engine and start moving. To disable the option, you will need to enter the combination on the key fob.
Car with a key on the grant panel
With a similar indicator, the car indicates the normal operation of the standard immobilizer. More details about the module are provided above.
Battery light on panel
If a similar indicator appears on the dashboard, you will need to immediately check the condition of the generator set and its wiring. It is recommended to perform a battery diagnostic.
The airbag icon is on on the dashboard
The light indicates that the activator module is faulty or disabled. In the event of a collision, the device will not operate.
Possible faults
If everything is clear with the description, then let’s move on to the malfunctions. Like any other electronic component, the Lada Granta instrument panel is also susceptible to various malfunctions.
What kind of breakdowns can occur in the operation of the control panel:
- The tidy is broken. If the shield fails, there can be quite a lot of symptoms. For example, only some or all of the devices will refuse to work. If this is the case, then the problem in this case may lie either in the power supply of the device or in its board. It is better to entrust repair problems to specialists.
- The tidy is glitchy. For example, all doors are closed and the unlocked door indicator is on, or the optics are not turned on, but the corresponding light on the dashboard is flashing. As a rule, in this case the problem lies precisely in the board (of course, if the sensors are working). If the problem is in the board, then flashing the dashboard firmware can solve it, but this option does not always help. It is possible that the electrical equipment lights are on on the dashboard due to a faulty sensor, so it would be a good idea to check its functionality.
- All devices work, but there is no backlight. If all the backlight bulbs do not work at once, then most likely the problem lies in a blown fuse or a damaged wire or connector. Checking the wiring is done using a multimeter.
- Only part of the light bulbs or one of them does not work. In this case, the malfunction consists of a burnt-out lamp; to eliminate it, the instrument panel in the Lada Granta is dismantled, after which the burnt-out lamps in it are replaced.
- The equipment indicator on the dashboard does not turn on. For example, you turn on the high beams, but the corresponding light does not light up. This may be due either to a failure of the indicator itself (the lamp is changed in the same way), or to a breakdown of the sensor. It is quite possible that there is poor contact between the light bulb and the wiring.
- Speedometer failure. The cause of the malfunction may lie in the board or speed sensor installed on the device. The situation is similar with sensors - fuel level, engine temperature. If they do not work or show incorrect values, then the problem should be looked for in the controllers themselves, wiring or board. It is possible that the devices are not working simply due to poor contact.
Errors on the panel

What are the designations for certain display modes?
The green color of the alarm means the correct operation of the systems for which these icons are responsible. Their yellow or orange glow warns of possible malfunctions, and red indicates the presence of such malfunctions that can lead to significant damage or a critical reduction in the safety of the same FL Grants.
If, after starting the engine, its icon (1) continues to light or flash, this means there is a malfunction in certain engine systems.
If the low pressure alarm of the internal combustion engine lubrication system (4) flashes even after starting the engine, this indicates the need for visual monitoring of oil leakage, and then including a bench check of the operation, starting with the oil pump and ending with the pressure reducing valve.
As for the ABS indication (5), the stabilization system is working properly if this icon goes out within a couple of seconds after the engine starts.
But the cooling system overheating lamp (7), provided that it is properly controlled, should go out after a 5-second interval after the engine starts running.
If there is an alarm about a brake fluid deficiency (8), then in addition to checking for the optimal level, you should definitely check for critical wear of the pads.
When the engine is running, the airbag status icon (26) should not light up if the active safety system is working properly and is turned on.
All this means that the Granta FL dashboard is intuitive and also as informative as possible even for novice drivers.
Control system controllers
The electronic control unit (ECU) is the “heart” of the vehicle’s electrical system. It is he who is responsible for the correct fuel injection, prevents the occurrence of emergency conditions, controls the combustion process of the fuel-air mixture and issues error signals. Failure of the Lada Granta FL ECU is not uncommon.
Factors such as climatic conditions, gasoline quality, and vehicle operating modes often interfere. The standard ECU contains the factory logic for controlling both an 8-valve engine and a more powerful 16-valve engine.
The controllers are manufactured in Russia by the Itelma Research and Production Enterprise. The cost of the product reaches 11,000 rubles. The price depends on the method of ordering the component, the remoteness of the delivery region and the supplier company. You can buy a unit directly from the enterprise for 6,000-6,500 rubles.
ECU functions:
- adjusting the fuel supply advance angle;
- idle speed control;
- control of injection volume in modes;
- stopping the engine in an emergency.
If one of the cylinders begins to operate unstably, a surge appears, ignition disappears, and the power sharply decreases. The ECU sends primary signals to the controller to turn off the fuel supply. Despite the age of VAZ models, the plant still uses controllers of the “January” type, versions 4, 5 and 7. Some car enthusiasts tune Grants and install Bosch control controllers.
Replacing a controller is a difficult operation that requires professional knowledge and understanding of the operating algorithm of the vehicle's electronic system.
ECU firmware
The control controller software is replaced in two cases:
- for forced increase in power;
- in case of car malfunctions.
Auto tuning enthusiasts resort to the first method. When installing non-standard camshafts, timing parts, or replacing the standard throttle valve with analogue versions, it is necessary to change the firmware. Otherwise, the car will generate dozens of error codes at the first start. Non-standard parts change the algorithm of the ignition system. The operation of “reflashing” the ECU should only be performed by specialists.
The second option is used in the event of a malfunction in the electronics, leading to a complete failure of the vehicle control system. Such a malfunction can occur either due to a manufacturing defect or due to mechanical damage to the controller. Specialists completely clear the electronics memory, and then install the standard control program again.
After any ECU flashing, the stage of setting up and adjusting the car follows. All parameters are checked: the quality of mixture formation, the actual fuel supply, the sequence of cylinder operation, the temperature in the combustion chambers, etc.
It is worth noting that only by reinstalling the controller operation algorithm can the vehicle’s original factory power be restored to 100%. This is achieved by removing “forced locks and restrictions” that the ECU system activates when the cylinders malfunction.
If two icons are lit, “exclamation mark” and ABS
This often happens when two icons light up on the instrument panel at once, for example, an “exclamation mark” and an ABS icon (or a stabilization system icon in the form of a “car on a crooked path”).
Since the car’s braking system is often very closely connected with the ABS system (Anti-lock Braking System) and the motion stabilization system, if a malfunction occurs in one of these systems, the second may also stop working and/or be forced to turn off on-board computer. Therefore, if two icons appear on the instrument panel at once, you will have to look for a fault in two systems at once.
If, after troubleshooting the brake system, the icons on the panel do not disappear, then you will have to look for it in the ABS system (or stabilization system). However, it is necessary to make a reservation that it is very unlikely to find a malfunction in the ABS or stabilization system by simple inspection, so if two icons appear at once, it is best to immediately contact a car service center (or read the errors yourself).
