Comma AI self driver assistant

The long cable (both of them, throw codes immediately) same issue as before

They are expected to throw codes immediately. We need to know if they go away after the software is fully up.

If your comma looks like this and you are still getting errors on the truck is what we are looking for.

Happy to report I have taken my first drive with a fully functional and operational Comma.ai. Thank you both for your assistance. Should I just wait now for the breakout board and just do a start up according to these simple tests till then?

The only thing you should have to do is wait for the software to boot if you were able to get it working. Is your AC working?

Everything is working as it should and no codes.

I would recommend waiting for the next batch of adapters since you aren't having any major issues. You can reserve one here. https://bluepilot.dev/lightning-coupler-order-page/

First off a big shout out to both UncleTony ad Ajzride in helping me getting my comma working on my 2024 F150 Lightning Flash. As a side note the factory long USB cable would not work. I used a USB C 3.2 Gen 2X2 Video Cable, 20 Gbps Data Transfer, 240 W, 10ft, and that is when the comma finally came to life and the error codes disappeared. I have paid the deposit for the adapter and cannot wait to put in on. Thanks again. What a great forum.

If you have a soldering iron, you can create a temporary board to stop the startup errors while you wait. Left is the temprary one I was using in a 3d printed case and right is @UncleTony's.

Thanks. I can give it a go. Is it just the one resistor or is there a link with directions?

 

[PJnc284]

yeah just one 360 ohm resistor soldered on the board between A10/A11. Resistor side goes toward the comma when hooking it up. I'd just mail you the one I was using but I'm 2 hours away from it and won't be back there for a week or two.

This is great information. Thank you for the help. Much appreciated.

You can add a touch of glue to the inside male side to keep it from pushing into the case. You can also heat the top side wire of that resistor to get the solder to flow into the hole. You may end up with a weak solder joint if its only holding the resistor in on the bottom.

Probably missed it, how was 360 ohm resistor figured for reducing CAN Bus reflections at the C3X end?

edit: found the explanation in posts #548, #551

ha. I had planned on adding more solder after I made sure it worked but got lazy and didn't feel like unhooking it. And I knew I had your fancy one coming so didn't need to last long.
