You are plugged in correctly, the black port (2nd from bottom) on the IPMA. I am blown away that you have two harnessess and multiple cables and can't solve the issue. It is possible you have a C3X with a bad USB port, it has happened once before.

If your have plenty of limit on your credit card, I would just order a new C3X and see if the issue is sovled. If it is do a return on the bad one, they have a pretty easy 30 day return policy (just cost $10 in shipping, it's worth $10 not to deal with the warranty department). If you don't want to order a second one for testing, then we can try to find someone close to you that you could connect theirs to your truck (and yours in their truck).

Noted, given how much i've read about said interaction I think i'll do just that. I was wondering the same thing but I didn't know the frequency or likelihood so didn't want to assume it would/would be on the device connection end

yeah, i went to best buy and bought 2 new 3.2 gen 2

3.2 gen 2 is not the same. USB c 3.2 Gen 2x2 has extra super speed pairs the comma needs.

usually a cable that doesn’t meet spec will refuse to go on road, not give errors. but a known working cable from Amazon is a cheap and quick check. At least cheaper and quicker than a new C3X from Comma in Cali.

I have gotten that error plenty of times while testing. Specifically when I removed the extra super speed pairs.

sorry i should have been specific, yes they are the 2x2, and have the dual lane 10g up and down; also, one did intermittently work for like 30 minutes so it would be strange to be able to function and then stop if it was not the correct type.

Then I would agree that the comma seems to be defective. You can always try your thunderbolt cables for good measure. They should operate the same, as they are the same as 3.2 gen 2x2 internally (In this use anyways).

Edit - Disregard the TB suggestion, I see that you already tried that earlier on.

Are you getting dashcam mode? Or an error?

I corrected the post, did it on phone and thought the pictures attached to the post.

 

[Ajzride]

I’ve been sitting on the comma trying to find time to install it, but got around to installing it today and I’m getting stuck on unavailable.

Apologizes, i thought the pictures attached.

Additional Notes: I have tried it under OpenPilot and BluePilot and get the same error.

I am very confused, maybe this is the reason for my errors. I followed your video, in the video you mentioned the first plug. the grey one as being the correct plug. So that is the plug mine is plugged into.

Ya,

I wish i would have caught that, i watched it up to that step and then stopped, figured i was done.. weirdly it drove just fine with it plugged into the grey plug, just the comma didn't work.

Now i might be in a pickle. I just went and switched it to the 2nd plug, the black plug and now i get a million boot errors and the truck won't start, stuck in park in the garage. I just disconnected the battery, because right now the truck is stuck in the garage blocking it from closing...
Sigh..
Hope reconnecting the battery fixes things "fingers crossed", i have not purchased forscan yet to be able to clear anything if that is the fix.

Did you swap it while the truck was on? The comma harness should just act as a passthrough without open pilot booting. I don't see how swapping them would cause issues. But AJZ may be more familiar.


You might see how quickly you can get one of these delivered https://a.co/d/ejjBWOB.

I disconnected the negative on the battery every time i have unplugged those wires. It was when i connected the battery back to the truck and tried to boot it that it had all the errors.

Are you 100% sure the harness's are plugged in all the way? If they are and you are still getting errors, you can try removing the harness and reverting back to stock to see if the errors go away.

If you are able to post the errors, that would be helpful as well.

I think you shorted your comma harness box. There were a few MachE users who did the same thing. This is exactly why I made a Q4 specific video:
