When you cranked the truck, did the screen on the comma show the cameras?

No

99% of the time this is a cabling issue. Do you have the long USB cable that comma sent? If so it has been found to be hard to plug in. You have to push it until it clicks, which can take firm pressure.

You can always remove the device from the windshield, connect it under the dash with just the short cable that comma sent to help determine if the long cable is the issue.

No

Did I miss something on the start up of the comma ?

Used the cable from my Apple laptop, fired right up, taking it for a test drive.
Thank you!

That's because the long cable is technically what causes the reflections. But the radar error sounds more like a cable issue.

Reseated all the cables and tried both the USB that came with the comma and a different USB (USB C 3.2 Gen 2X2 Video Cable, 20 Gbps Data Transfer, 240 W, 10ft) with the same issue. on start up I get Pre Collision Assist, Service Advance Trac, and steering assist. When I start driving I also get the other codes below. They do not go away until I unplug the USB and restart.

With everything plugged in. Turn the truck off and remote start it. Wait about 5 minutes before you turn on the ignition and see if the DTC's clear.

Plugged everything in. Remote started for 5 minutes before starting. Did this several time. No joy. Could there be something I am overlooking?

No, just trying to separate the normal startup errors. If you are still getting errors, it is likely you have a hardware issue. Most of that should clear once openpilot/bluepilot takes over. Are you able to make a breakout board?

I am not that good, although I did pay my deposit today. I suppose I could give it the old college try. Always up to learning a new skill

I know you already tried another cable, but you can try removing the comma from the windshield and plug it directly into the harness box with the shorter 90 degree that comes with it. It's always possible the coupler is bad.

Progress. No codes attaching the short 90 degree cable directly to the harness

When you used the other (long) cable, did you have the purple coupler in place?
If you did, try both cables plugged directly into the comma. Nothing else inline.

No. Not with the short cable. plugged directly into the harness. no coupler

now try just the long cable by itself with no coupler or short cable

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