**** the VSC system.

I extended sway bar end links on the rear today with the use of the Moog front sway bar end links part#K90681. I also put on the Prothane 18-1116 Red 19 mm Rear Sway Bar Bushing Kit. Now, VSC OFF and VSC TRAC lights are on. I tried zero calibration and disconnecting the battery. Shits still on.

What to do next?

I've had those two light up once or twice random, when I was driving over really rough pavement and the major vibration threw those lamps along with a unrelated check engine. Was able to reset the check engine via bluetooth OBD interface and free android app via google play store. Resetting the check engine put out the lights for VSC and TRAC too. If you've got a check engine lamp lit along with the others this may work.

If no check engine, my guess is changing the vehicle's stance may have upset the yaw sensor calibration. If you google 4runner yaw calibration pretty sure that will pull up something.

There is no check engine lamp on. And I have already done the yaw calibrations multiple times. But as soon as I put it in reverse or drive and it rolls a couple of feet. The VSC OFF and VSC TRAC comes back on.

First of all you have to pull the VSC codes. A fancy scanner or a Toyota scanner(Techstream software) will do. There is also a way to do it manually, found in the FSM. Figure out what is causing this and go from there.

There's no way those codes came up simply because you changed your sway bar bushings. My guess is that you maybe accidentally pulled one of your wheel speed sensors loose. The only real way to find out is to scan for the codes. It's a hard code, which means that no matter what you do to reset the light, it will always come back on meaning there is an automatic failure, which is possibly the wheel speed sensors.
