Good to know, thanks!

I’m using the fuse tap for power.

Did you also remove the AXM power connection if you're using the harness from Comma?

Good call. I have not removed that connection. Certainly something to try next.

Yeah, that can cause issues as well. Generally recommended to use either fusetap OR AXM power, but not both at the same time. Using both has the potential to send power feedback through both systems.

I’ll check the harness but looking back through the instructions it says that as of July ‘25 the Lukas harness is not using the AXM for power and is using the fuse tap. I bought my harness + fuse tap from Lukas in early July. https://docs.google.com/document/u/0/d/1clodGRssTx-dSPSUrQITq_vqumgWcpSUw83zdcAZR-A/mobilebasic

I also need to check which fuse I’m tapped into. I think it may be F34 and if so can try moving over to F33 though that has never been a problem in the past.

Ah, ok, you have a Lukas harness. That's a different story.

Yeah, that shouldn't make much of a difference in this situation. You're not pulling current from the AXM so fuse location isn't going to affect anything on the AXM itself.

So, possibiltiies are the harness itself is bad (unlikely) or it's just an unrelated problem with the AXM or a related module.

Today I had this error when I had forgotten to put the Comma back into on-road mode. So the Comma was "half there" and seemed to lead to this. I parked, put it in on-road, and it was fine. This leads me to wonder if you may have a connection issue, particularly with the USB cables. Unfortunately that is hard to troubleshoot unless you have a couple of known good cables.
