Auto leveling VSC ABS warning lights

Auto leveling VSC ABS warning lights
So a few weeks ago I had my coilovers installed on my 99 ls400 and once I got everything buttoned up all of these warning lights came on with no check engine light. I have searched and could not find anyone else with this problem. It could be a fuse or relay but I do not know where to begin. Any help would be greatly appreciated.

Ok Puredrifter this now makes sense I read somewhere that I could have a bad speed sensor or when I did the suspension swap that I may need to adjust my abs sensors as well. I think I have narrowed down the problem, check the abs sensor connections or a bad speed sensor.

I think I may have found my answer on another thread

In case this can help someone.
The Lexus manuals are useless for this problem.
There are 2 motors which consist of each headlight adjustment.
There are only 2 sensors which are located on both right front and rear lower control arms. They have a large "n"looking hoop to allow the sensor to be adjusted up and down.
The arms usually bend and need to be straightened out every so often to work properly. The front sensor never needs adjusting so leave it alone.
When the car is started it turns the system to do a check and raises the lights to max up and down position before leveling out. If you get a "headlight malfunction on your readout after driving for a few meters and have an ABS light it is because the ABS light is on and disrupting the system. Fix the sensor and it will disappear. If you disconnected the arm and left it hanging it still would not trigger a fault on the ecu for having no change in output.
How do i know these things?
I bought my car and noticed the rear sensor was hanging. No issues with it not working except blinding oncoming traffic. Fixed it 3 times by welding it ,but it kept snapping off for some reason of torsional pressures.
Had my car worked on by the dealer and they broke a ABS sensor which threw my headlight sensor on also. Could not figure it out for weeks as i waited for the sensor to be installed. Realigned the arm and no change. As soon as the sensor was fixed the light disappeared .
I am now a sane man again with no dash lights.

Wow that's my old thread. My problem ended up being a halfa** attempt at splicing and taping the wires when My headlights were stolen ( Do they still steal HIDs lol ) I found the loose wires after years of dealing with it and being lazy and soldered the wires along with heat shrink. Matter fact let me update that thread just close it out lol.

Well My VSC light has been on for a long time. Once replacing the routers and brakes on my 2003 GS which has nothing to do, we found that the thin part was disconnected right by the control arm. Which when I got into my car to drive it , it had the worst wringing noise like a fire alarm,with a brake sign lit up. So the disconnected piece, I just moved it up and the sign came off. Im just wondering what is this part called, and how do you fix it. So i figured it has something to do with the VSC system, just a pain in the ****
