Noticed a torn boot, VSC TRAC, VSC OFF, TRAC, ABS lights were on during only 2 mornings when there was high humidity, drove a short trip and they went out upon restart. Can't remember if the check engine light was on, I'm thinking it wasn't.
Tonight I checked the ABS codes and got the c1223, U0123, U0124, U0126, no check engine light is on.
c1223 abs control system malfunction
u0123 lost communication with yaw rate sensor module
u0124 lost communication with lateral acceleration sensor module
u0126 lost communication with steering angle sensor module
Had the brake light switch so I've swapped that and took a ride around and still got the codes. Both brake lights are coming on, everything is operating as expected.
At this point I am going to continue to monitor it being I just changed the switch and the hope of it still cycling out, though I know at some point I would correct the CV boot issue.
