Default ABS and TRAC Off

The ABS and TRAC Off lights are on in my dash on my 1998 Lexus ES 300. What do these mean? Thanks in advance.

has the suspension been replaced? If so, it could be a broken speed sensor.

The lights illuminate when the system detects a fault. The next time you turn on your car, check something. When you start the car, does the ABS light flash and then stay lit? Does it not come on at all until after all the others have gone out, or does it just come on and stay on continuously?

These can be used to help isolate the problem. As mentioned before, the weakest link in the ABS system are the wheel speed sensors, but any number or electrical and mechanical faults could trigger the light, including low fluid level which can simply be caused by low pads, so check all the hardware before you let loose any money on electrical diagnosis.
