At least that gives you a starting point. Hey, we can talk to this guy, this guy and this guy. We can't talk to the trans controller. We can't talk. We can't talk to the tip. We can't talk. And so on. Right. So it would be it would be really great. And it would save you some diagnostic time if you could bring it to them in failure mode.
