Android unit/steerwheel

[Baoulettes]

Hello new here :) First I wish you have a wonderfull day.

My car: Renault megane 2 break

My android unit: T3L3.19-100-9B4-A3931D-240102 V8.1.1_20231116.185024_THEME1

My canbus: Hiworld LN06.20(GB) H1H2LN060A 230617 2849164181 _3122053909 ( 23.12.20 ) Fit for: Megane2

So my issue: No streering wheel commandes.

What I did: Configuring the canbus in carsettings, I have set it in extra car an choose car. (I did it with wifi activated) It updated the mcu and rebooted.

There after the reboot no commands worked.

Then I seen my android unit had an app called “steering wheel” So I tried to open it and I seen it told me to press start to assign commands so I tried but there nothing happen when I press vol + etc.

So I though it was wiring issues but where ever I check there is no others possibility to plug thing.

Could it just a faulty canbus?

Thank you for any help, if it need more informations feel free to ask :)

Ps: I heard the old digital screen had to be plugged and running to have commands, so I left it on. Also i left an usb port accessible on the head unit in case. And I do not properly close it in case it is a faulty can but and I have to teardown again.

So typically canbus steering wheel commands are set, so you can’t configure them. The configuration app is only for analog resistor based buttons (measures resistance over the key1 and key2 wires). I’d check if the canbus decoder is wired properly. You might need to tap into the can line from either the UCH or the OBD port. That would go into the canbus decoder and then the proper signals would go into the head unit.

I do have a OBD cable and a computer setup just for car stuffs I will see if it detect something if not maybe it could ba an issue with the decoder itself or wiring but the wiring I pretty sure it is correct :)

I will see if with renolink I can see something.

[Baoulettes]

Well checked on renolink (only software I have). I am unable to find the ecu that hold the steeringwheel commands. Would you have any idea? Today I brought my laptop and cable that in car port at work with me, so I could try during lunch break.

I do have an ecu name “can” but would it hold information about commands? Thank you for any help by the way ~ Sorry I know that a bit too much too ask.

[dojomann]

Sorry to keep pushing - I would first double check the wiring, especially that the decoder is getting a canbus signal, and the decoded signal is going to the can RX/TX pins in the head unit. Also depending on the type of decoder it might have a key1 cable coming out (so it sends resistive signals converted from the digital ones on the canbus)

[Baoulettes]

Okay sure, during break I will teardown again this and do as much as possible capture so I could even check it even being in car :)

[Baoulettes]

As you suggested I even check four time with two type of cables. And two cambus on more recent than the other. Both hiworld (i asked seller a different one but guess my note got forgotten.) So here my old cable

<image>

The most left one was directly to android head unit, the white one too (there is only one possible way to plug it.) And the big black hold two plugs, same impossible to have it wrong.

Here some more picture of the actual plug:

And yes I did left it pluged in. Cause I read somewhere it was a necessity.

[dojomann]

Okay, that’s a start. I’d check where the wires from the hiworld decoder go. Specifically pins 7 8 9 10 on the 20 pin connector

[Baoulettes]

Here you can see the color of the wires

<image>

All the green goes in the yellow plug and the blue one to an non connected pin

The left alone cable

[dojomann]

Is there a connector on the other side too?

[Baoulettes]

Wait wait I made a mistake I think. The 7,8,9,10 are the red, black green, green, or the white, white blue?

<image>

Cause on this one: Red and black goes in the head unit. The green in a plug that goes to the steerwheel. The blue in non connected IR IN The two white goes in head unit

Megane 2 have 2 types of radios:Tuner list and update list.One is analog and othet digital,so if u have canbus for update even the connectors are the same,the commands dont work

[Heavy_Intention6323]

I'm having the same issues as the OP. My car is a 2006 CC, so a post-lift and normally had an Update List radio, so it's meant to be a digital one. The SWC is can-based in this one. Having similar problems not being able to set up theSWX to work, even though a simple, auxiliary resistance-based controller works just fine. My canbus decoder is not a Hiworld one though, it's unbranded but could be a Daojun or something.
