Vsc trac / vsc off lights on

[Brutalguyracing]

so i have an 03 v8 limited runner
and i had a wheel bearing going out
then the vsc trac and vsc off lights light up as soon as truck rolls forward about a foot
any ideas
no work was done that would have stretched out any sensors or anything
i thought it was because of the wheel bearings but i just replaced them today and lights are still on even after battery was disconnected

any thoughts
tips
trouble shooting ideas
thanks

I have been thru a few ABS/Speed sensor wires. Last one that failed, failed from unplugging it. They are unusually fragile. Do you have access to a Techstream? If so you can see if the speed sensors are registering at each corner. Also helps with doing a ZPC.

Nope dont know what a tech stream is
With my taco u could use a paperclip and pull codes for airbag and abs
Unsure about runner

Use 5million dollar sst or a jumper wire

All this i suspect is from my ultra gauge
Same as taco
Problem started not ling after a problem with the ultra gauge now that i think about it

I still need to sell my yaw rate sensor from my taco
