Well. I think you need to deal with that shade tree wire problem before anything else. Post a picture of that. If it really is "wrapped around the stabilizer link a few times??? " I would love to see that.
Gravel drive ? No empty asphalt or concrete parking lots in your area ? Not saying you need to do major repair work there but at least a place you can take a look at your car.
Or a set of car ramps and a sheet of carboard to lay on.

U2142 00 is lost contact with the yaw sensor
U2143 00 is lost contact with the PSCM
U1500 00 is the GMlan is shorted or open.
Look at fuse #19 BCM.
Check fuse #56 & #57 & 61 underhood.
Check the connectors on the EBCM.
Has anyone messed with any of the wires around the BCM or under the hood or around the gear shifter?
The (C0460) PSCM and the (C0292) Yaw sensor both connect to the EBCM for 12V power and ground. Check the ground for the EBCM.
If the yaw sensor is not connected the 12V is turned off to the PSCM.
The yaw sensor is under the waterfall area near the BCM.
"Lost communications with" does not necessarily mean faulty module. More likely a blown fuse, a loose wire etc.

When you did the fogs? That’s when the problem started? Retrace your work, did you dislodge a ground wire? Splice into any wire harness? Have you removed the bulbs from the fogs, did the problem stop?

Question, with battery disconnected awhile while doing the fogs, on an uneven, sloped gravel drive , would that throw anything off when battery was reconnected? Becaause I dont get why the YAW and steering sensor would all the sudden be off when it wasnt before?
