CANBUS Set up on Nissan Juke Tekna 2011 (DUDU7)

chicken13

Hello everyone,

I'm seeking some help with my new DUDU7 head unit. I'm trying to set up the CAN BUS protocol for my 2011 Nissan Juke Tekna, but I'm having trouble getting it to work correctly.

Here's the information I have:

1 - Describe the specific problem encountered:
Impossible to set up the CAN BUS protocol for my 2011 Nissan Juke Tekna on my recently received DUDU7 unit. I can't find the right option in setting menu (XP(simple)>>Nissan>>?)

2 - Your vehicle's make, model, and year, Car Center Control Pictures:
Nissan Juke Tekna, 2011.
Please find bellow my car's center console and the CAN BUS box.

Note: During the installation, I didn't find a spot for the grey connector (circuled in red)

3 - System information:

Any guidance or advice on how to get this working would be greatly appreciated. Thanks in advance for your help!

You can try a few more options. What car features are not working right now?

chicken13

Thanks for the reply.

Right now, none of the steering wheel buttons (volume, next/previous track, etc.) are working. The air conditioning controls are also not functioning.

The only thing that seems to be partially working is the reverse camera. When I put the car in reverse, the screen switches to the camera interface, but the image is completely black.
I've already tried to configure the CANBUS by setting it to XP (Simple) >> Nissan >> Qashqai >> High or Low, as I saw suggested on some forums, but that didn't fix the issue.

I appreciate any further suggestions you might have.

chicken13 you don't have the rear camera connected. That's why the image is black. From your pictures you have only the CANBUS connected.

chicken13 In Settings-CANBUS-Steering Wheel Button Learning, is it useful to learn the corresponding buttons?

chicken13

Thanks MihaiFlorin for the hint. I don't know how I missed it 😅.

It's now connected and it works. Thank you!

Hope will be the same with steering wheel buttons.

dudu-lai hi,

Steering Wheel Button learning doesn’t work either. I guess it’s normal as my car using CANBus protocol.

I thing the problem come from the CANBus configuration on the HU or directly from the CANBus box itself.

Is there checks I can make?

Thank you.

Recorded with a mobile phone camera, CANBUS log of pressing the volume up or down button, and the up and down buttons 3 times respectively

chicken13

dudu-lai please find bellow the video and the canbus log.
Hope I've done it the right way.

chicken13 With this, I really don't know. I am not an expert. But I am sure that @dudu-lai will help you with this if you provide the logs.

I downloaded a video, but the data is blurry.

In the video, it's unclear which button you pressed: the volume button or the previous/next track?
You can set the background to black for better clarity.

chicken13

dudu-lai done.
Thank you.

chicken13

dudu-lai I’ll do it better.

I pressed Vol+, Vol-, Next, Previous three times each as requested.

Hello,

I've re-recorded the video as requested.

Here is the link to the video.

I pressed the following buttons three times each, in this specific order:

Next

Vol+
Vol-

Hang up

I've also attached the CANBus log file.

I've been in contact with the seller's customer service, and they pointed out that the "Version Information" shows "Unknown CANBUS," which indicates that the CANBUS type has not been successfully selected and activated.

Indeed, when I select a CANBUS configuration (with an active internet connection), nothing happens. Should the device update or reboot, as I've seen in videos of other Android head units?

Thank you in advance for your help.

chicken13 The video is well-recorded and contains useful information. Please be patient. Today is the weekend and the engineers are not working. The analysis will not be completed until tomorrow.

chicken13

dudu-lai hope you’re doing great.

Did you get a chance to analyze the video and logs sent?

Thanks a lot.

The engineer analyzed that the CANBUS box was not sending SWC-related information and therefore had no data.
You can try connecting the SWC signal cable to the DUDU and learning the steering wheel buttons in the DUDU.

PA6 connects to G7
PA16 connects to G6
PA15 connects to G1

chicken13

Hi,
I just wanted to follow up and say thank you for your help.
I have just finished making the connections exactly as you suggested (PA6 to G7, PA16 to G6, and PA15 to G1). I'm thrilled to report that it worked perfectly! The steering wheel controls are now fully functional after using the head unit's learning feature. I'm happy with this result.
I am, of course, a little disappointed that I can't make use of the CANBUS data, but having a working solution for the controls is what truly matters.
Thank you again for your support!

dudu-lai

chicken13 OK, thanks for your feedback
