Berlingo 2016 reset tyre pressure warning light

[hvegh]

After replacing my Berlingo car radio with an andoid based navigation system. I noticed that I needed the menu in the car radio to reset the tyre pressure warning light,
Just wondering there may be a CAN bus message that resets this light. Is there any info on this?

Hi, sorry for the late answer, unfortunately I don't have the corresponding CAN frame for that :(

No worries thank you for replying!

I have a NAC retrofitted in my 5008 and if I push the button "Reset tyre under inflation" or something like that it emits this message:

0x1A9 20 00 DE 00 FF 01 50 00

Where 01 seems to be the reset request (without pressing the button, that place has 00)

what AEEE do you have? is that berlingo with RD45 or with something newer?
Because I do have a radio from 2017 Berlingo and I am having problems with it not accepting signal from the Source button due to unknown factor. I would be able to give you modified firmware so you could gather the traffic that reaches the radio unit. But sure, you already got the new headunit unfortunately.

the source button is on the steering wheel media stalk. the specific message that hits the radio is what I am looking for. The whole thing is making very little sense to me. There is a closed issue where I was banging my head against the wall :D I can link it later (#60 - there it is)

I have to say if you have 2016 berlingo I would say its tough to believe they gave it RD4 in factory but it can be the case. I would expect that there is some unkown there somewhere. if you would just keep hitting the source button and get it either via bridge, I would be able to compile current bridge firmware, that would just print it in the web interface and you would just paste some screenshots. thats quite easy way forward. or some can device thats sniffing packets would be really great.

Reading that you have some device, well congrats. This is super promising. When you would obtain a dump I would be so much closer to my goal. Because everything works perfectly beside that button.

anyway, how can I help you with the tire light? is that something you did via RD4?

Hi @hvegh how is the board? I might buy it too. looks good. I will need to think it through

[Comodore125]

Hi just want to state that the issue is fixed. So there is no need for data from berlingo as I found then in research and also @morcibacsi did fix it in advance.

The board is perfect! I just connected the can bus and the signal ground pin to the OBD connector in the dashboard.

Select network device "Geschwister Schneider UG and candleLight compatible interfaces" and the canbus generics as kernel modules.

On linux just do:
ip link set can0 up type can bitrate 500000
candump can0

It gives you tons of messages, I still have not found the time to replace the RD4 radio and to perform the tyre reset procedure... :(

But I can recommend the device.
