Okay the fuses and relays are all seated properly.
Does the hub hold the wheel speed sensor?
I am wondering if this behavior, combined with the previous post I made about the random "Service ESC" warnings, combined with the odd growling/groaning I am hearing when I turn to the left (see video) is all adding up to "replace the right front hub"?

My last ABS problem was the caliper slide pins, the right side lower pin was seized so the brake wouldn’t apply fully, causing the tire to turn different speed from the left front, and yes tge wheel speed sensors are in the wheel hubs.

And yes probably related. Easy to check hubs: jack the wheel off the ground push/pull on the wheel; if you can sense ANY movement the hub is bad. End play tolerance is 0.001 inch.

Check the sensor wires and connector before you buy anything. The intermittent nature of the problem suggests a bad connection. This is not uncommon.

Does it really read tire pressure?

No play at all in the wheel. I'll see about taking it off later and see if I can check the connection. It's already 99 degree heat index this morning.
