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.
Yeah, it looks like someobe did it to keep it from just flapping in the wind..... Ill get a pic soon

If I go into town, Im in the sticks.... gravel and dirt everywhere
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.
From U1500 diagnostic aids:
No one has messed with anything other than me doing the fogs since returning from my trip, only issue was fuel guage went wacko on the way home from that trip. But everything else was normal. I will check fuses tomorrow and try to get a pic of the hub wire wrapped around the link pin. if I can get the plug off Ill unwrap it and get it right... not much room to reach it with tires turned and no where to jack it, cant get it in the garage yet til I get the mower back together ( waiting on a part still ) Just baffles me with some of the codes like steering sensor and all as I didnt have it before disconnecting the battery and doing the fogs?
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?

No splicing, the original wiring was intact behind the bumper. So, I didnt mess with anything other than the cover to pop the new fogs in and plug the harness into fogs and replace the cover and plastic rivits. only thing other than that ws I disconnected the battery because I was going to try and pop the airbag off to do the switch but didnt .
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?
