Fully disabled Mazda TCU (Telematic Control Module)!

[M^Coder]

Hi,

This is huge!

I was able successfully disable the TCU (Telematic Control Module) in a 2023 Mazda CX-5.

Finally no spying, no Issues wit TCU under CMU. No DTC's related to TCU gone because it was disabled entirely!

Under CMU Connected Services also gone!

I'm ready for selling solution or share knowledge for price that compensates my effort.

So how did you do it?

Excuse me?? You can't just drop something like that and casually walk away like nothing happened!! Seriously though, please tell, I'm really interested in how you did it.

Well, I can share my knowledge but not for free. I put really a lot of effort here and resources.

This whole low level reverse engineering requires lot of log analyses and some brilliant ideas
