Corvette CCM Reverse Engineering Anyone?

[kur4o]

FOund the mode5 code in the bin, but there is not much that it can do. It seems the ccm enters some loop where you can upload custom code. It still doesn`t make sense since there is no execute visible in the loop.

Also I think I spot the bit that prevents the mode5 entering. It will be esily patched if we have access to writing a custom bin.

Now the main question. What should I expect from mode 5.


Edit;

I think some polling of the ccm will be great. Sending different modes and submodes commands over the aldl bus and recording the reponse.

The CCM ID is f1 or f0. There is also tons of other ids in the code, but it will take some time to figure the usage.
