Key system default

Сообщение Хмурый » 17 апр 2019, 13:44

Добрый день. Не нашел похожей темы, открываю новую.
Сегодня не смог открыть машину с брелка. Механическим ключом открыл, на экране высветилась надпись Key system default. Естественно, завести невозможно. Поменял батарейку в брелке — ноль эмоций.
Звонил дилерам официалам — поступило очень интересное предложение — «приезжайте, сделаем диагностику».
Может кто сталкивался с такой проблемой? Автомобиль Ниссан Кашкай 14 года, передний привод, LE+

Пуск двигателя возможен только с помощью ключей, зарегистрированных иммобилизатором (иммобилайзером).
Возможные причины отказа иммобилизатора (иммобилайзера) разрешить пуск двигателя зарегистрированным ключом: – прикосновение ключа к металлическим или магнитным предметам; – прикосновение к ободку замка зажигания металлической части другого ключа; – соприкосновение ключа с другими ключами, связанными с системой иммобилизатор (иммобилайзер)а, или с ключами других автомобилей.
В этих случаях удалите от ключа металлические предметы, поверните ключ в замке зажигания в положение «АСС» (питание дополнительного оборудования) или «LOCK» (блокировка). Затем еще раз попытайтесь пустить двигатель. Если двигатель пустить не удалось, обратитесь на сервисную станцию, так как дальнейший поиск неисправностей возможен лишь при наличии специального диагностического оборудования.
ПРЕДУПРЕЖДЕНИЕ.
Внесение изменений (подключение дополнительных потребителей) в электрические цепи иммобилизатора (иммобилайзера) запрещено, так как это может привести к выходу его из строя и, как следствие, невозможности пуска двигателя. http://nissan-qashqai.dv13.ru/elektroob . bilizator/

водителя закрыта, а ключ системы Intelligent Key находится
вне автомобиля, в то время как выключатель зажигания на-

I’ve heard/seen something about waving it in front of the push button start, to get the car to recognise it again. Not sure if it actually works or not though

That has always worked on mine; just do what icon is showing you what to do on display, when this occurs.

I have the same problem at the moment. In U.S. there is more comment about it. Each time we have eventually got car working again by fiddling with the steering wheel.

When the battery being changed doesn’t work we move to the following:

Engine start function is controlled by
Door lock function + Power distribution system
NATS- security sub system in the Intelligent Key. (this is key/car coded communication)

The vehicle security function can operate only when the door lock and power distribution systems are operating normally.

If the doors respond to the key correctly then 2 items above can be discounted perhaps. The car recognises its Key ID when the doors lock/unlock.

Assuming the clutch is depressed and no other key is in the car the engine should start. Not necessarily and the Key ID is checked again.

Does the steering lock/unlock at anytime ?

There are many other reasons the car will not be allowed to start and most of them have DTCs (error codes) recorded. Without knowing recorded code(s) its impossible to diagnose the problem.

Key System Fault Nissan Qashqai [How to Fix Guide]

The Nissan Qashqai is one of the most reliable cars on the market.

However, this Japanese SUV does have its faults, and one of them is the “key system Fault” alert coming on the dashboard.

In this article, I am going to explain what the key system fault message means on your Qashqai, the main causes, and how to fix and reset the message.

Nissan Qashqai Intelligent Key Overview

In order to understand what might be causing the “Key system fault” warning on your Nissan Qashqai,

I think it’s important first to understand the Intelligent Key system.

The Nissan Intelligent Key system is a remote key fob that allows you to do different things other than just locking and unlocking the vehicle.

This keyfob allows you to perform various functions, such as:

1. Opening and closing windows from outside the vehicle,
2. Turning on daytime running lights,
3. Making a sound when locking and unlocking from a distance.

Additionally, the key remembers your saved settings, such as seat position, mirror adjustments, and climate control, for your convenience.

With so many advanced features come some drawbacks like Fob battery drain and more.

What Does “Key System Fault” Mean on a Nissan Qashqai?

In simple terms, when the Key system fault message comes up on your dashboard

It means the vehicle has detected that one or more of the components of your key system is malfunctioning.

This could be anything from a bad key fob battery to a wiring problem.

What Causes the Nissan Qashqai’s “Key System Fault” Alert?

As I mentioned above, an array of things can cause this issue,

But after seeing a lot of Qashqais with this problem, I’ve narrowed it down to five causes:

1. Bad Key Fob Battery:

The number one cause of this issue is a bad key fob battery.

Similar to other vehicle brands, Nissan keyfobs come equipped with a battery that provides power to the key and enables Intelligent remote functions.

Typically the key fob battery will last anywhere between 3-5 years of usage,

However, key fob batteries on Nissan Qashqais are known to fail prematurely.

Leading to the “Key System Fault” alert on the instrument cluster.

2. Bad Quality Key Fob Battery:

If you recently changed your Nissan Qashqai Key fob battery then it is possible that the new battery isn’t working properly.

This can be a result of poor-quality batteries,

Since your Intelligent key requires comes with a lot of complex features, it requires a specific battery,

If you have purchased a generic key fob battery, then there is a chance that it will not work properly with your Intelligent remote.

This is another common cause of the key system fault message.

3. Faulty Brake Sensor:

Another possible cause of a “Key system fault” message on a Qashqai is a malfunctioning brake sensor.

Before starting your vehicle, the brake pedal sensor sends a signal to your Intelligent remote indicating whether or not the brake pedal is being pressed.

If this sensor malfunctions, it cannot send the signal, causing a key system fault message to appear on your screen.

4. Bad Battery:

The battery on your Nissan Qashqai can also cause a key system fault message to appear.

The battery powers a lot of electronics in your car; If your battery is old or damaged, it can cause different electronics to malfunction due to low voltage, including the key system.

5. Wiring Issue:

The last and least common cause for a key system fault message is a wiring problem.

The Data Communication Module (DCM) wiring on your Nissan Qashqai is responsible for transmitting information from the ignition to other systems in the vehicle.

If there is a short or break in this wire, it can cause the key system to malfunction and display a key system fault message.

How to Fix and Reset Nissan Qashqai “Key System Fault” Message

Now that I have gone through the most common causes from my experience as an auto technician,

Let’s get into how you can fix the problem.

Replace the Key Fob Battery

The first thing that I would recommend is to replace your Key Fob battery with a quality one.

I personally prefer Duracell fob batteries because they have a higher power output and last longer than other brands.

In most cases, after replacing the battery, the problem should be fixed.

Make sure that after you replaced the key fob battery, you disconnect and reconnect the battery terminals to completely reset the system.

Have the Battery Tested

If replacing the Fob battery does not solve the problem, then you need to have the battery tested.

This can be done by taking your Qashqai to a Nissan dealer or local auto parts store or taking it to a mechanic and having them test out your 12v battery.

If the battery is going bad, replacing it should solve the issue.

Take your Car to the Nearest Nissan Dealer/ Qualified Mechanic

If changing the fob battery and testing the 12v battery have not solved the issue,

Then the culprit might be a faulty brake sensor or wiring, which would need to be looked at by a Nissan Tech or any qualified car mechanic.
