How to connect buttons on the <em>Nissan Qashqai</em> steering wheel: diagrams, errors and compatibility

Steering wheel control buttons Nissan Qashqai is not only a convenience, but also a mandatory safety element that allows you to control the audio system and phone calls without being distracted from the road. However, after replacing the standard radio with a post-warranty one (for example, Pioneer, Alpine or Android Auto) many owners are faced with a problem: the buttons stop working. The reason lies in the differences in data exchange protocols between the original head unit and the new multimedia center.

In this article we will look at all ways to connect steering wheel buttons on Qashqai (including models J10 2007–2013 and J11 2014–2021), consider pinout diagrams,More adapters and typical installation errors. We will pay special attention non-obvious nuance: on restyled versions J11 (since 2017) a modified CAN protocol is used, requiring a special adapter that supports CAN FD. If you are planning to install it yourself, get ready for soldering work or purchasing ready-made solutions.

Why do the steering wheel buttons stop working after replacing the radio?

Original radio Nissan (For example, Bose or Clarion) exchanges data with the steering button control unit via CAN bus protocol. When you install a third-party head unit, it is not physically connected to this bus, so the signals from the buttons are simply ignored. There are three ways to solve the problem:

• 🔌 CAN-bus adapter - the most reliable method that preserves the functionality of all buttons (including voice control on J11).
• 🔧 Flashing the radio - suitable for some Android-devices with support Steering Wheel Control (SWC).
• 🛠️ Direct connection via analog protocol - a cheap but limited solution (does not work on all models).

It is important to understand that Nissan Qashqai different generations use different protocols:

If your Qashqai released after 2017, be prepared for the fact that cheap adapters (for example, ASWC-1) will not work. In this case, you will either need Radio firmware for CAN FD, or purchasing a specialized adapter for 8–12 thousand rubles.

Steering wheel button connection diagrams: step-by-step instructions

Before you start connecting, make sure you have:

TORX T20 screwdriver (for removing steering column panels)

Multimeter (to check voltage)

Soldering iron with solder (if you plan to solder wires)

CAN-bus adapter (compatible with your radio)

Electrical tape or heat shrink

Plastic clamps for fastening wires-->

Let's look at the two most common connection options: via an adapter and direct connection to the radio.

Option 1: Connection via CAN-bus adapter (recommended)

This method is suitable for most radios (Pioneer, Sony, Android) and retains full functionality of the buttons. Procedure:

1. Remove the bottom panel under the steering wheel (unscrew 2 screws TORX T20 and carefully snap off the clips).
2. Find the connector for the steering wheel buttons - it is located behind the steering column switch (usually a gray or black 6-pin connector).
3. Connect the adapter to the button connector according to the diagram (see below) and to the radio via ISO- connector
4. Program the adapter for your radio model (instructions are included with the device).

Pinout diagram for Nissan Qashqai J10/J11 (standard button connector):

1: CAN-H (жёлтый/зелёный) → CAN-H адаптера
2: CAN-L (белый/зелёный) → CAN-L адаптера
3: +12V (красный) → к аккумулятору или магнитоле
4: GND (чёрный) → масса
5: Подсветка (оранжевый) → к габаритам
6: Не используется

Option 2: Direct connection (analog protocol)

This method is only suitable for radios that support Steering Wheel Control via analog input (for example, some models Joying or Xtrons). Here, the signals from the buttons are transmitted not via CAN, but through a resistor matrix.

To connect you will need:

1. Find the contacts on the steering wheel button connector SW1 And SW2 (usually pins 1 and 2 on a 6-pin connector).
2. Solder them to the input SWC on the radio (see the instructions for the device).
3. Adjust the button resistance in the radio menu (usually this is done through the service menu).

⚠️ Attention: Direct connection without an adapter may result in loss of functionality of some buttons (for example, voice control or track switching). In addition, on Qashqai J11 after 2017 this method does not work due to protocol changes.

Choosing an adapter: which one is best for Nissan Qashqai

The market offers dozens of adapters for connecting steering wheel buttons, but not all of them are compatible with Qashqai. We tested the most popular models and compiled a rating based on reliability and functionality.

For owners Qashqai J11 2017–2021 the only reliable solution remains Metra AX-NIS32 or NavTV SWC. Cheap adapters (like ASWC-1) will not be able to process the protocol correctly CAN FD, which will lead to broken buttons or errors on the dashboard.

Common connection mistakes and how to avoid them

Even experienced auto electricians sometimes make mistakes when connecting steering wheel buttons. We have collected the most common of them and ways to eliminate them.

• ⚡ Short circuit when soldering - if you solder adapter wires to the button connector, make sure that the exposed areas are insulated. A short circuit can damage the steering column control unit (repair cost - from 15 thousand rubles).
• 🔄 CAN-H and CAN-L mixed up - if after connecting the buttons do not work, and the dashboard lights up Check Engine, swap the yellow/green and white/green wires.
• 🔊 Incorrect adapter firmware - many adapters (for example, ASWC-1) require selecting a vehicle model in the setup program. If you select the wrong option, the buttons will not work correctly.
• 🚗 Lack of mass — the black wire of the adapter must be securely connected to the car body. Poor contact leads to “floating” malfunctions in the buttons.

⚠️ Attention: If an error appears on the dashboard after connecting the adapter U1000 (CAN bus malfunction), immediately disconnect the device and check the correct pinout. Working with this error for a long time can lead to malfunctions. ABS and ESP.

Another common problem is buttons work, but with a delay. This is due to the low priority of CAN messages from the steering wheel buttons. Solution:

1. Update the adapter firmware to the latest version.
2. Check the voltage on the CAN line (should be ~2.5V between CAN-H And CAN-L).
3. If the problem persists, install CAN filter (For example, CANtact).

Connecting steering wheel buttons to Nissan Qashqai with Android radio

Android-radio tape recorders (for example, Joying, Xtrons, Dasaita) require a special approach when connecting steering wheel buttons. The main problem is the lack of a unified protocol SWC from different manufacturers.

Here are step by step instructions for Android-devices:

1. Make sure your radio supports Steering Wheel Control (check model specifications).
2. Connect the adapter (eg ASWC-1) to the CAN bus and to the radio via USB or 3.5mm jack (depending on model).
3. Install an application to customize the buttons (for example, SWC App or Button Remapper).
4. Program each button manually (the application will prompt you to press the button and assign an action to it).

On some radios (for example, Joying Jupiter) steering wheel buttons are configured through the engineering menu:

1. Зайдите в Настройки → О телефоне.
2. Нажмите 5 раз на Номер сборки, чтобы активировать режим разработчика.
3. Вернитесь в Настройки → Для разработчиков → Steering Wheel Key.
4. Выберите Learn Key и нажмите каждую кнопку по очереди.

⚠️ Attention: On Android- radios with a processor Rockchip PX5 or PX6 may be required manual file editing swc_config.ini in the root directory of the device. Without this, the buttons will fire randomly.

The cost of connecting the steering wheel buttons in the service vs doing it yourself

If you are not confident in your abilities, you can contact a car service. However, prices for this service vary greatly depending on the region and the complexity of the work.

Self-connection will cost only the cost of the adapter (from 2,500 to 13,000 rubles), but will require time and accuracy. If you have never worked with a CAN bus, it is better to entrust the work to professionals - connection errors can lead to Steering column control unit malfunction (new price - from 20 thousand rubles).

Average cost of a self-installation kit:

• 🔌 Adapter ASWC-1 — 4,500 rub.
• 🔧 Soldering kit (solder, rosin) - 500 rub.
• 📶 Multimeter (if not) - 1,000 rubles.
• 🔄 Connectors and wires - 300 rub.
