Hello i have Alfa 159 with universal android head unit, and i need to connect Can Bus Box (alfa-bg-01) but i dont have the necessary wires, jst the box. Can anyone with the same box send me the scheme how to connect the wires to the box?

Hello, @hortar @typos1
I have Alfa 147, with same head unit (seller : mookaka / I have a very bad feeling on them).
I have no wheel keys detection.
How exactly did you resolve your issue ?
I found hu connector has not cable in front of car connector :x . I changed it but it still does not work.
What the cable in yellow connector stand for ?

Do not worry You will find the edge. If you take your car to a specialist they will find it. Do not do it alone, unless you know so well about car electronics

@hortar did you set SWC key or CAN key in factory settings to make it work ?
Do you have picture of your wires ? in which we can see wire's colours

No unfortunately. I don't have photos. Look this video. I dont have other information, sorry my friend. I m sure that you solve the issue.

Hi All,
I have just bought a previously used head unit (alps ff-5000) in a local store for my Alfa 159 and luckily it can show canbus info on the screen like open doors, outside temp, voltage. Is that possible to display the trip computer data as well? What about aircon? It doesnt work by default but maybe it is possible to enable it with some trick.

Is it an MTCD/E unit ? Why do you want to display the aircon controls when they are literally a few cm below the head unit ??

When I asked my technician he told me not to worry because all I would do was cause a serious problem in the car

That is nonsense - it would not cause any problem at all, but youd need something to decode the signals from the CAN Bus and display hem,like a Arduino and custom software.

Hi everyone

It is a very interesting thread that can solve many problems for many people.

I have been trying to troubleshoot problems with my Alfa 159 for a long time.

I have doubts, please I hope you can kindly help me:
1- The canbus box, should I remove it?
2- Key1 to C10 - Key2 to C11 - GND (signal earth) to C12 in alfa 156, but in alfa 159, is it the same?
3- Would it be possible to configure door opening, battery, temperature, or exclusively SWC?
3- Edit: I understand key1 key 2 only SWC. Canbus: temperature, doors, a/c...

@typos1 , Do you happy with canbus box bagoo alfa-bg-01 in alfa 159? Show doors, temperature, battery... in alfa 159? Do you need plug wire key1 and key2 for SWC with this canbox?
Would someone be so kind as to point me out where I could buy it?


Thank you very much and congratulations for the great thread worked




Edit 17/10/2021 16:52:
Surprise! I have removed the radio and I have the canbus bagoo Alfa box.

Maybe it is badly wired, if not I do not understand anything. I have taken pictures of the connections and the diagram of the radio.
I have only found the key1 cable unconnected. I understand that the key2 must be plugged into the canbus box but I'm not sure.

I read in the thread to user @ Pachis83: "I only had to re-arrange the unit connector pinout, respecting the original schema for my unit, and setting the right canbus box model type in the factory settings"

I hope someone can help me please.

Thank you very much again

    I know there are a lot of versions of CanBox but it's hard to find a bit more information (except some photos). So I decided to do a small reverse engineering of my version.
    Someone will ask for what? Out of curiosity. Maybe will be helpful for someone in the future. Maybe someone will share what version he has.
    But most of all because maybe someone has a firmware for the MCU? Maybe @hotaudio has such firmware (bin file or CANBUS.UPDE file) to any version of Canbox and help us? :) For educational purposes, of course.

    That's how my CanBox looks like

    This is the effect of my reverse engineering:

    I attached schematic diagram in PDF and schematic/pcb made in KiCAD (ver4 and ver5)

    And here other photos of CanBoxes what I found

    Ok, thanks, can you upload photos of your schematics ?

    I didn't save them. Anyway you can go ahead without schematics:

    There are two groups of cables: the ISO connector ones and the canbus box ones.

    The cables regarding the ISO connector is as simply as comparing the two wiring harness. For example for GND pin in ISO connector, you have to check that ends in the same pin in the unit connector. Most probably these cables will need a complete re-arrangement. Search for Alfa 159 ISO connector schematics on google and compare against the schematic wich is on the unit itself regarding the connector, you have to match all (GND->GND, RR speaker->RR speaker, etc...).

    Regarding canbus cables, you will need a voltage tester. The box will have more or less the following cables:

    • Power supply and GND, for powering the box. You will differente them because are tied to +12V and GND pins in ISO connector. These two cables won't need any modification.
    • Canbus cables to the ISO connector, for "talking" with the car. These cables won't need any modification.
    • Ignition signaling. You can identify this cable by testing it with the voltage meter. You will get 12V when ignition turns on. Double check it's connected to the Ignition pin in the unit connector.
    • Lights signaling. You can idenfity it by testing with the voltage meter. You will get 12V when low beam is on. Double check it's connected to the light signalig pin in the unit connector.
    • Can A and Can B, bus connection from the box to the unit. Make sure they are connected to the proper pins in the unit connector.

    In this way the specific unit schematics are not needed. I made the mod without them.

    Regards.

    Or more appropriately have Wheelkey Study disappear when that setting is set to SWC Key. I'm thinking maybe they mean "you can change the assignments" when set to "CAN key" but since it's so close to Canbus it gets confusing very quickly.

    Do they mean "use Canbus" or "can" (like "are able") to change/assign." I can see how other language speaking people have a hard time understanding some of our words that have many meanings in context.
    "CAN SWC on" and "CAN SWC off" would have been more logical. Still, I bet their English is better than our Chinese !
    Is the program on the display of the controls on the screen, is it part of Android 10 or is it something special?
    No, it appears on all Android versions, its MCU controlled, see @jlbooths's new thread linked to above.

    I have an Alfa GT as well. The GT (and 147) has CAN Bus, but it has resistive steering wheel controls, the 159 has CAN Bus and the steering wheel controls are CAN Bus too. The CAN Bus you are using is really meant for an Alfa 159, not the Alfa GT (or 147). I use this CAN Bus box too because it also works with most of the functions on the GT, but not all functions because it is meant for the 159. You need to use @Hal9k_'s cutom ROM (you may have to downgrade to Android 9 until his 10 is ready) because his ROM lets you over ride the CAN Bus steering wheel controls - at the moment they are set to CAN Bus controls because it is an Alfa 159 box you are using.

    Youre kinda of right - if the unit is set to no CAN Bus (ie universal units and even some cars with CAN Bus eg Megane 2 & BMW E46) or to a CAN Bus car that has resistive SWC the SWC app works and the SWC setting is automatically set to allow SWC butttons to be changed.

    Its whether they can be changed on a car that has resistive SWC and a CAN Bus box not designed for it like @hortar and my cars without the key wires being connected. I ll try in a few days, maybe @hortar can let us know if his works and whether the key wires have to be connected or not.
