VSC lights

[4runnerAzGuy]

A while ago I installed some total chaos UCAs and stretched out one of the abs wires. I was getting the abs light plus both VSC lights on. I replaced the wire and the ABS light turned off. Now the VSC lights are off when I'm stopped but once I start moving they come on and stay on until I turn the truck off again. Any ideas what's it is?

Go have the code pulled. You are might find a bad wheel speed sensor.

I had the VSC, VSC trac, ABS and traction light on like 2 weeks ago. It would turn off when I turned off the car. It would only come on sometimes and stay on until the car was off. Tried the calibration and that didn't help. Had the code pulled and turned out to be a brake switch. Bought the part from the dealer for ~$40 and replaced it and it has not come on since.

I can't remember the code but I'll find it and post it up.

Find someone local that has a TIS Tecstream and check the wheels speed sensors to insure they are all properly displaying speed. I have been thru 2 ABS/Speed sensor harnesses. If they get stretched or the slightest bit damaged they fail. Also make sure you run the full calibration. I didn't the first few times and my VSC lights lit back up fairly quick. Also every time on the 2004 the battery gets disconnected the yaw/speed sensor crap needs to be re calibrated. Much easier with TIS then the manual obd2 wire process.
