System ERA-GLONASS, mandatory for all new cars in Russia since 2017, raises a lot of questions among owners Lada Granta. Many consider it an unnecessary additional equipment, which only increases the cost of the machine and creates the risk of data leakage. But is it possible disable GLONASS on Grant without consequences for guarantee and legality? In this article we will analyze all the methods - from software deactivation to physical removal of the module, and also tell you what this threatens in 2026.

It is important to understand: the ERA-GLONASS system consists of two parts - emergency call (automatic accident notification) and transport monitoring (coordinate tracking). By turning it off, you lose not only “surveillance”, but also potential help in a critical situation. However, if the decision has been made, let's figure out how to do it as safely as possible.

Why do Grant owners want to disable GLONASS?

According to surveys of car owners, up to 40% of Lada Granta buyers are considering the option of deactivating the system. Main reasons:

  • 🔋 Low battery: The module consumes energy even when the ignition is turned off, which can become a problem when parked for a long time.
  • 📡 Potential data leak: Fears that the car’s coordinates may be used by third parties (although officially the data is encrypted).
  • 💰 Maintenance cost: Some modifications require payment of a subscription fee for the SIM card of the module.
  • 🔧 Difficulties with repairs: If a module breaks down, replacing it costs 15–25 thousand rubles.

However, there is also a downside: according to statistics from the Ministry of Emergency Situations, in 2023 the ERA-GLONASS system helped save more than 12 thousand people in road accidents where drivers were unable to call for help on their own. Before making a decision, weigh the pros and cons.

📊 Are you planning to disable GLONASS on your Grant?
Yes, definitely
Only if it does not affect the warranty
No, I think the system is useful
Haven't decided yet
Already disabled

From a legal point of view, the situation is twofold. According to Federal Law No. 395-FZ (on the mandatory equipping of vehicles with emergency call systems), intentional shutdown or damage to the ERA-GLONASS module can be regarded as:

  • 📜 Violation of vehicle operating rules (fine up to 500 rubles under Article 12.5 of the Administrative Code).
  • 🚨 Avoidance of mandatory safety requirements (in the event of an accident without the system triggering, problems with the insurance company may occur).
  • 🔧 Warranty void on the car (if the shutdown is detected when contacting the service).

An important nuance: on January 1, 2026, Order No. 421 of the Ministry of Transport came into force, tightening control over the performance of ERA-GLONASS systems during technical inspection. Vehicles with a faulty or disabled module may not receive a diagnostic card.

⚠️ Attention: If you are planning to sell a car, the lack of a working GLONASS system may cause a price reduction or buyer refusal. Many banks require confirmation of the serviceability of all mandatory systems when providing car loans.

Technical ways to disable GLONASS on Lada Granta

There are three main methods for deactivating the system. The choice depends on the year of manufacture of the car and modification of the module:

Method Difficulty Reversibility Risks
Software shutdown via diagnostic connector Medium (scanner required) Yes Possible errors in the on-board computer
Physically turning off module power Low (access to fuse box) Yes Loss of emergency call functionality
Removing the SIM card from the module High (panel disassembly) Yes Loss of seal, risk of corrosion
Re-flashing the ERA-GLONASS block Very high (specialist required) Partially Loss of warranty, possible failure

The safest and most reversible method is power outage. To do this:

  1. Open the fuse box (located to the left of the steering column).
  2. Find the fuse F30 (10A) - it is responsible for powering the ERA-GLONASS module.
  3. Remove the fuse. The system will be deactivated, but without physical removal.

⚠️ Attention: On Grants 2022–2026, the ERA-GLONASS module is integrated with the system Lada Connect. Disabling it may lead to malfunctions in the mobile application and remote control services.

Step-by-step instructions for software shutdown

For owners who do not want to interfere with the electrical system, there is a way to deactivate it through the diagnostic connector OBD-II. You will need:

  • 🔌 Adapter ELM327 (version 1.5 or higher).
  • 💻 Laptop or smartphone with the program OpenDiag or ScanTool.
  • 🔑 Access codes for service functions (for some software versions).

Algorithm of actions:

  1. Connect the adapter to the connector OBD-II (located under the steering wheel).
  2. Launch the program and select a model Lada Granta.
  3. Go to section Electronic systems → ERA-GLONASS.
  4. Select an option Deactivate Emergency Call (may be called differently depending on the software version).
  5. Confirm the action and wait until the system reboots (takes 2–3 minutes).

After disconnecting, the indicator on the dashboard may light up ! in the form of a car with an exclamation mark. This is normal - the system signals a module malfunction. To clear the error, you will need to reset through the same diagnostic scanner.

💡

If after disconnecting an error appears on the panel U110E (malfunction of the ERA-GLONASS module), it can be ignored - it does not affect the operation of the car. However, during maintenance, it may be necessary to temporarily return the fuse to its place.

What happens if you completely remove the GLONASS module?

A radical method is physical removal of the block. On Lada Granta The ERA-GLONASS module is located behind the center console, next to the climate control unit. Its dismantling includes:

  1. Removing the decorative trim of the console.
  2. Disconnecting the power and antenna connectors.
  3. Removing the module from the seat.

Consequences of such a step:

  • ✅ Complete absence of surveillance and energy consumption.
  • ❌ Constant error on dashboard (ECU firmware is required to remove it).
  • ❌ Warranty issues - dealers AvtoVAZ The absence of a module is easily identified.
  • ❌ Inability to pass inspection without "cheating" diagnostic equipment.
How to cheat diagnostics with a remote module?

Some services offer installation of a “fake” - a resistor that simulates the presence of a module. However, this solution is temporary: modern scanners (for example, Bosch KTS) recognize the substitution. A more reliable way is to flash the ECU with removal of the ERA-GLONASS check, but this requires specialized equipment and costs from 5 thousand rubles.

Alternative solutions: how to reduce risks without shutting down

If you're worried not so much about surveillance as low battery or service cost, there are less radical ways:

  • 🔋 Installing an additional power switch: Allows you to completely de-energize the vehicle, including the GLONASS module, when parked for a long time.
  • 📶 Replacing a SIM card with a tariff without internet: The module will work but will not transmit data (although the emergency call will remain active).
  • 🛡️ Antenna shielding: Metal foil around the antenna blocks the signal, but this may affect the operation of other systems (for example, Lada Connect).

For Grant with system Lada Connect It is important to disable only the monitoring function, while maintaining the emergency call. This can be done through the mobile application:

  1. Open the application Lada Connect.
  2. Go to Settings → Privacy.
  3. Disable the option Transferring coordinates in the background.
💡

Even when monitoring is turned off, the ERA-GLONASS system will automatically transmit coordinates in the event of an accident with airbags deployed. This function can only be completely deactivated physically.

Common mistakes when disabling GLONASS and how to avoid them

Many owners Lada Granta encounter problems after turning off the system on their own. Let's look at typical mistakes:

Error Reason How to fix
Constantly on Check Engine Power off without resetting errors Use a scanner to reset codes U110E and B1100
The radio doesn't work The ERA-GLONASS module is connected to the CAN bus responsible for multimedia Restore power or reflash the radio
The car won't start Short circuit when removing fuse Check fuses F20 and F25, replace if necessary
Error during maintenance Diagnostic equipment detects the absence of a module Temporarily return the fuse or install a "fuse"

If after disconnecting there are problems with electronics, first check:

  1. Integrity of fuses in the block.
  2. Presence of errors through the diagnostic scanner.
  3. The state of the contacts in the module connectors (if it was physically removed).
⚠️ Attention: On Grants with robotic gearbox (AMT) The ERA-GLONASS module is connected to the transmission control system. Disabling it may cause jerks or delays when shifting gears.
Is it possible to disable GLONASS without opening the hood?

Yes, on some modifications Lada Granta (2020 and newer) you can deactivate the system through the on-board computer menu. To do this:

  1. Press and hold the button SETUP on the steering column switch.
  2. Go to Settings → Service → ERA-GLONASS.
  3. Select Operating mode: Off

However, this method does not work on all firmware versions.

Will the alarm work after GLONASS is turned off?

Depends on the type of alarm:

  • 🔴 Standard alarm (with key fob) - works without changes.
  • 🟢 GPS/GLONASS alarm (for example, StarLine M31) - will lose the tracking function, but the main security functions will remain.
How to check if GLONASS is really disabled?

There are three ways:

  1. Call the number 112 from the phone registered to the car. If the system is active, the dispatcher will see the coordinates of your car.
  2. Use a diagnostic scanner to check the status of the module (a code should be displayed Not Available).
  3. Check the current consumption when parked: when the module is turned off, it will decrease by 0.02–0.05 A.
Is it possible to turn off data only and keep the emergency call?

Technically this is possible, but requires flashing the module. This service is not officially provided, but some services offer “lightweight” firmware, where:

  • 🔄 Function saved eCall (emergency call in case of an accident).
  • 🚫 Background transmission of coordinates is disabled.

The cost of such firmware is from 3 to 7 thousand rubles.

What should I do if the climate system stops working after turning off GLONASS?

This is a typical problem for Lada Granta FL (restyled version). The reason is the common bus wire connecting the ERA-GLONASS module and the climate control unit. Solutions:

  1. Return the fuse F30 in place.
  2. Reflash the climate control unit (a specialist is required).
  3. Install a decoupling resistor (120 Ohm) into the gap in the CAN-H wire between the module and the climate control unit.
