C# J2534 Tool

Post by The1 »

Hi All,

Trying to make a simple utility to Read a specific Message or Write a Specific Message for CAN bus.

I have it loading the VCX Library atm for the VCXNano cable but later once it's working id put auto detection or manual selection in.

With it hooked up to a VZ ECU it should send a VIN request and ECU return the first line without a 30 poll, the filter is set to all so i should get something back not 0 returned.

My C# skills are non existent im more machine code lol. Ive attached the visual studio 2019 project.

Code: Select all

I tried your tool, but it didn't work with the GM MDI, I changed the code to point at the mdi dll but it still fails.. I didn't have time today to try and sort out why, I'm just learning c# as well, lol..

Is the VCXNano J2534 complaint?, I thought it was.

Does the bruteforce program work with the VCX nano? It's using a different DLL from a github repository that I had found, not sure if it is but it seemed the easiest to get started with..

I need a J-tool, is this the correct one, GM VCX Nano??

Sure do have a distaste for their greedy nature ... Vehicle MFG specific tools!

thanks guys for the input, yep i have the VCXNano, i got mine for about $90, i looked at other cables and this was the cheapest that did J2534 and also GM tech2win. Its been working great.

I have figured out my errors mainly the string formats i think and have it fully working now including library selection. It's really a template for my other ideas now. It's also handy then to for other people to use.

Ironduke i tried that library but didn't have much luck for some reason.

Code: Select all

Nice work!! I'm not anywhere I can give this version a try right now but I'll give it a go when I can..

I know you have to send it a 0x01,0x30 message in order for it to send the rest of the vin.. Someone may correct me but the 0x10 after the 0xE8 indicates a multiline message, given this you need to send a 0x01,0x30 anytime you see the 0x10, it usually indicates the size of the message if it's 7 or under..

Watched some C# tutorials last weekend
Got your program working with MDI

Anybody had any luck with VB.net and J2534?
I think i should give up on VB.net and J2534 :comp:

I agree that you should give up on vb.net, and try c#. Its more popular, and a more mature language, with lots of help around. Once you've come on board with it you wont look back.

i was in the same boat, was VB especially back in Version 6 days, as soon as .net came VB went to crap so now i use C and C#. Especially easier cause there's more predone code and talking to windows and other library's is easier.

Is it possible that we can modify J2534 library work for mitsubishi M.U.T. III Software because only work MUT VCI interface....But there are those who create VCI_Bridge for Connect PassThru device after open M.U.T Software but very expensive cost.

I've seen a program like this that can PassThru device and M.U.T III software without MUT Interface.

What is your opinion?
