Help with VSC lights - No CEL

[brianhuntRVA]

On cold startups I am getting the VSC Trac, VSC Off and ABS lights, but no CEL. I can shut the vehicle off and start it right back up and the lights will be off.

I went to Autozone to have the codes read but there were none they could pull.

When I installed my suspension spacers, I damaged the wheel speed sensor wire. This was 2ish years ago. I repaired the wire and everything has been fine since until just recently. But at that time I got the same lights plus the CEL. Since I don't have the CEL this time I'm thinking it is not related.

I've read a number of threads on similar problems but none exactly to what I am experiencing. Any help would be greatly appreciated.

Mine did that when I got into it just now. By chance, could it be that your truck isn't level when you start it? Mine was at an angle because I was parked in the snow bank. After moving to a flat part of road and restarting it, the lights went out. It may have nothing to do with it, I'm just guessing.

Well I may have fixed this unintentionally. I went out Saturday to play in the snow and locked the center diff. Unlocked it when I was done. Yesterday and today I have had no warning lights. Maybe coincidence, time will tell...

Wanted to followup on this so there isn't misinformation floating around in this thread for people in the future. After a few days the lights came back on. I replaced the previously-repaired wheel speed sensor harness, with the battery disconnected during the process, and all has been good for about 5 days now. Easy job and pretty cheap to get the OEM part on Amazon.
