Seeking Advice on Intermittent AdvanceTrac and Hill Start Assist Errors

I am looking for advice for intermittent errors on my 2015 F150 XLT 4X4: “Service AdvanceTrac,” “Hill Start Assist Not Available,” ABS, and traction control lights come on. No limp mode or rough running, but cruise control fails. Forscan shows U0415 code. Cleaned connectors, no loose bolts. Errors vary in frequency, no correlation with weather or towing.

I recommend checking the wiring harness above the parking brake for any loose connections. If the problem continues, you might need to replace the front wheel speed sensor or the brake caliper guide pin.
