So the next thing to look for is the string hex codes that goes from the IHU to the IPAC, to report Clock, and what not perhaps?

And what about those who have the Highline Audio with the fancy Audio Amp under the seat where the signals passes threw a fibre cable? Can the IHU be completly replaced with some self made electronics and some intense programming to mimic the IHU, so It can be interfaced with an aftermarket stereo or tablet or car computer or what not?

If this was possible, THAT would have been awesome!

just my ramblin for today, Pay no attention to it, Or can you?

Mr.P

Absolutely, i'm pretty much following this guide from sparkfun: https://learn.sparkfun.com/tutorials/can-b...1456521414. I have the exact same hardware setup but I had trouble with Sparkfun's Can Bus Shield library. It seemed to me the IDs were not correct. Also, the examples did not work.

So I found a can bus library from Cory Fowler on GitHub: https://github.com/coryjfowler/MCP_CAN_lib. I felt I was getting better results. Cory's examples worked well and are very simple. I've expanded upon them but after reading this thread I've realized I made mistakes. After I resolve them I will post the code.

There are a lot of details I haven't decided for the rest of the goal I have in mind. In broad strokes, once I can read and write messages properly with the redboard/arduino I would connect it to a tablet and only send data relevant to my interface. The interface will probably be run on a windows tablet and written in C# just because that is what I'm familiar with. I'm still a long way off for most of this.

Are there other kinds of IDs? Are the IDs and prefixes defined in the above ISO standards?

I started a new thread regarding reading messages from the can bus. The focus will be on the 4x4 screen data with the intent of some day replacing the screen entirely: http://www.disco3.co.uk/forum/topic145750.html.

Questions I hope alex_pescaru can help with

Hi, planning to re engine a D3 TDV6 manual with a Chevy V8 engine running an aftermarket ECU - Megasquirt.
What Can Bus Information do I need to broadcast to keep the other Can Bus Connected ECUs happy and functioning and also to get the battery light, temp gauge and Rev counter working.

Unfortunately the Megasquirt can only broadcast 11 bit and the D3 will be 29 bit - will a Can Bridge be able to convert the data stream?

If not what signals are essential going into the TDV6 ECU to prevent it throwing a wobbly if I leave it connected and feed it a Crank and Cam signal as if the engine was still in the car.

Anyone who can help please fire away. Thanks

CAN bus reader

Hi Alex,

A very interesting thread. I've a mixture of different laptops and just bought a Raspberry Pi too. Not had a lot of programming experience, but plenty of hardware & end user interface software use on large international networks.
I fully understand the costs involved in development and support and can see why commercial tools run from hundreds to thousands of pounds

Is there a universal standards table of reading a code received in response to an enquiry and then translating that code into a easy to read user message ?

Personally I prefer a large screen and keyboard to a tablet style device for clarity, however I see the benefits of a system compatible with phones and tablets for portability

I look forward to your next update Very Happy MY05 Discovery 3 G4 LRG4C-14 Stage 3 & 4 Bolivia Team Fleet 49

This is excellent stuff alex, just come across it.. Been struggling to diagnoise a canbus fault after sniffing the network. Your information is very enlightning and somethigng i am going to spend more time looking at. Are you still actively engaged in this project.
My challenge was that i dont know what the module ids are (RRS 2007 2.7tdi) i can work out a few. I can see one of the modules dropping off the canbus when the fault occurs.. (I am sure its the instrument cluster, but dont want to throw money at that if i am wrong.) DTC's dont help.

Can you help, do you know the ids' for the RRS or how did you go about working them all out. (unless you had a canbus in pieces) pulling fuses only got me so far.

This might also explain why there's such poor response to Alex's posts when he's trying his best to point people in the right direction ...

Hopefully though something will come out of this that we can all use. Thumbs Up


Well I for one appreciate the technical detail supplied by Alex

So here is an 'excellent' response to Alex's post

Thanks Alex and keep on posting the technical details for us wannabee techies

Take care

Well I've got the brass soldering iron on the gas ring now and it's warming up nicely, but as for all those technically bits I'm totally lost Confused however credit is due to those who understand it Thumbs Up Bow down
