Nissan Pathfinder harness+canbus issues

kryzys

Hi, I've just found detailed information about A/C control in my Nissan. I don't know why I didn't find this information earlier: https://github.com/rynbrd/r51-ecu/blob/master/docs/climate.md

At first glance, it is clear that the A/C operation should be initialized:
https://github.com/rynbrd/r51-ecu/blob/master/docs/climate.md#unit-initialization
It's possible that the problem lies exactly here...

As I've already bought CAN sniffer tool, I'll try to confirm these information.

I hope it will be helpful and someone from Raise will be able to update canbus box firmware to support my car

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.

dudu-lai I have logs for all A/C buttons and CAN communication in my car, I analyzed them a bit and I think I have CAN messages for A/C buttons that do not work with my CANbus decoder. Please tell me who should I contact to solve the remaining problems?

Should I start a new topic for these problems?

kryzys There is no good solution. Contact Raise engineers to see if they can help.

kryzys

dudu-lai Do you have any direct contact with them? Could you put me in touch with someone suitable?

dudu-lai

In the CANBUS log you provided earlier, the Raise engineer replied that no air conditioning data was received. So DUDU does not display air conditioning information.
You may be able to replace the CANBUS box of another brand to see if the problem can be solved.

dudu-lai Could you help me somehow to register a WeChat account? I do not have anyone to do it for me. WeChat needs another user to scan a QR code to confirm my registration 😐

@kryzys did you have any luck with this in the end?I have a 2011 Pathfinder with the same canbus adapter and having the same issue. I also suspect the issue is the post 2010 Pathfinders with Bose sound system use slightly different canbus signals for the climate control.

rotor_nut I'm in the middle of decoding CAN communication. Unfortunately, it takes time and I don't have much of it. For now, I'm not giving up and I'll definitely write here when I have any visible successes.

kryzys I’ve picked up a canbus analyser as well but also need to find the time. We’ll get there eventually. I’ll also post up if I have any luck.

kryzys дружище, я тоже поднимал эту тему, dudu- lai прав, у нас не две, а три кан-шины присутствует в магнитоле, основная canbus 74,90 pin, multimedia canbus 75,91 pin, climate canbus 76,92 pin, основной canbus, соединяется со всеми блоками автомобиля, multimedia canbus взаимодействует только с магнитолой, climate canbus, считывается и обрабатывается магнитолой которая отправляет полученную информацию в основную canbus для блока климата, причем многофункциональный переключатель отправляет сигналы для двух canbus по одним проводам, поэтому для работы кнопок климата нужен canbox с тремя шинами canbus, в canbox raise есть третья шина 17,18 pin , но в rz df 17 он, скорее всего не активен, нужен другой canbox, например g-rz df 67, я заказал, когда придет буду пробовать
