Nissan Pathfinder harness+canbus issues

kryzys

Hi,
finally it is installed. After modifying my harness media CAN started to work. Volume and buttons on central console work, but the biggest issue is that A/C controls DON’T.
Please tell me what can I do/check to make it work. Driving without working A/C in summer is not very pleasing 😉

Also factory rear camera does not give any picture. Harness documentation stays that it has proper (6V) camera power.

Vehicle settings look very poor (not many options) and it looks like they are not persisted (saved) after choosing A/C panel type it is not saved.

kryzys You will need to download the Touchscreen Assistant program from the App Store for controlling/displaying the air conditioner.
Does the stock car have a reverse camera or 360 camera head?
There is a tulip plug on the harness, are you connecting it to the Lotus header on the F zone CAM IN of the DUDU unit?

Hi,
after using my system for a couple of days I have few issues and questions. As I have written before it is installed with a little modified harness. Media CAN started to work. Volume and buttons on central console work, but the biggest issue is that A/C controls DON’T. I’ve installed Touch Assistant, but it didn’t help. The only thing that works is defroster button, but it is not controlled by canbus - it has its’ own wire. My canbus setting is correct:

Please tell my why canbus settings is so poor and what is „Air conditioning panel type”? Or should I also ask Raise about it?

So my first and most important question is how to make A/C to work? Please tell me if I should contact canbus box producer (Raise)? Can I help them with some canbus logs from the unit? Here is small video:

Touch assistant - only defroster works
As for factory rear camera. It looks like it is connected properly. I’ll try to find some more information and get back to you.
And the last thing… I think I have a broken fan in my unit. Check out video below. Can I replace it by myself? What fan should I buy?

kryzys 1：Air conditioning problems require logging of CANBUS logs, follow this tutorial https://forum.dudu-auto.com/d/846-how-to-give-correct-feedback-on-canbus-errors
2：Fan specifications are: 40*10

kryzys

dudu-lai I,ve bought standard 40x10 fan, but it turned out that it does NOT fit... nobody has said that it should be WITHOUT frame 🙁

It turned out that it is working, but a small plastic element was broken and it was causing noise. This element held the wires so they wouldn't fall onto the fan blades.

I'll try to get logs today...
Is it standard 12V? Will this one be suitable NF-A4x10 FLX

dudu-lai

kryzys It's a standard 12V

I've tried to get logs from canbus, but there is no output 🙁 What I'm doing wrong?

kryzys Video Recording of Air Conditioner CANBUS Problem Logs with a Cell Phone

kryzys

Where these log files should be stored? I was looking for canBusALog directory...

kryzys

Here is the video: AC operation

Only defroster works because it is not canbus operated, it has its' own wire.

What about these logs? Can you tell me how to find them?

kryzys

Also, the vehicle settings look broken to me. Other examples (screenshots from other cars) show much, much more settings. Is this possible, or is it my car that is just so poorly supported?

dudu-lai

kryzys The video is well recorded, the question is: the physical buttons control what the AC does, but only the defroster pops up to show at DUDU, the other AC buttons don't?
Am I understanding this correctly?

kryzys

Exactly. Defroster button is operated with its' own physical wire, so it displays AC popup and it looks like it works because defroster icon changes.
The rest of A/C buttons/knobs are operated by canbus and they do not work at all.

As canbus is the same for other controls on the console (volume, settings, etc.) it is strange, because everything except A/C wroks.

dudu-lai

kryzys The rest of A/C buttons/knobs are operated by canbus and they do not work at all（Does that statement mean that the physical A/C buttons, except for the defroster, the buttons are disabled? Like it's broken?）

dudu-lai

Just because the defroster can pop up an icon at DUDU doesn't mean it works. Just because the rest of the buttons (e.g. temperature, air speed) can't pop up icons on the DUDU doesn't mean it's not working. Can you confirm this?
The A/C buttons are OEM panel buttons, if none of the buttons work, check for incorrect installation!

kryzys

By "they do not work" i mean they are not correctly handled by HU/canbus box. Physically they are working okay, they are not broken.

One canbus line is connected to the whole console, so A/C is on the same canbus line as volume, FM/AM/Settings and the rest of buttons. But only A/C controls are not handled correctly

Here is my console (back) - it is connected by one connector:

Here is connector (yellow wire is defogger)

And here is connector documentation:

kryzys Any pictures of the CANBUS bus box?
And a photo of the connectors on the back of the OEM mainframe（Something like the photo below）

kryzys

Right now I cannot make a fresh photo, I must disassemble my center console 😐 But some older photos...

Back of original radio unit:

My canbus box is RZ-DF17. And here is my harness.

It had to be modified:

no AMP control wire - I did it by myself
canbus line wires were messed up - I corrected them and now canbus communication works

There is no data in the CANBUS log for the rest of the keys. You can't get this information in your modified CAN bus.
The wiring harness you are using, has a total of 3 sets of CAN buses, you can try connecting one of the sets, to CAN-L/CAN-H of the A/C connector to try if you can get the data

kryzys

I've also received documentation from Raise... I can send it to you.
