Is the CEL light on also?
Simple inspection of the wheel sensor harness at each wheel would be the first look. Then have the car plugged in to scan the specific code.

Wat does the cel light look like , the only light that's on is the red circle light looks like this (O) , which if I'm not mistaken the brakes needs to be changed which I'm about to do on mon

The CEL light looks like the engine.

Cel check engine light lmao dam I feel like dumb azz.. yea its on but for an o.2 sensor

The CEL light can be on to go with the trac light. Bring it to some parts store chain and have the codes read for that also. What the hell, it's free.

I have my own scan tool , an it only shows a code for the o2 sensor

Is it the "trac" or the "trac off" light? If it's just the "trac" light then you could just be low on brake fluid.

i had this happen once. i put one wheel on pavement and one on sandy shoulder and floored it. light went off and hasn't come back on.

What year is yours? Can you post the code? Generally this is an ABS issue.

I went to get my 97 ls400 smogged, and the technician couldn’t turn off trac with button (later found it was disconnected), he then broke the PAL fuse under hood for abs/trac, causing blinking abs and trac lights. Fixed the fuse and switch, went away.

Original fuses may have corroded/oxidized blade contact issues which may build circuit resistance over decades..

A post outlining condition of original fuses on my 1999 LS400 about six years ago.

​​​​​​Several circuits are not used, however this is not necessarily a good thing either when it comes to corrosion/oxidation/tarnish at contact areas over time.
