So I googled this issue with no avail. ABS Light is on and brake pads look fine. Anyone know what it could be? Car rides great and nothing is wrong with it otherwise.

Does your traction control flash at the same time? There is a way of checking the fault codes with a paper clip. You just need to short circuit terminals E1 and Tc in the diagnostic port, if I recall correctly. Then you will need to count the amount of times that the ABS light flashes to tell what number you're getting. Btw, this information is only for the 3ES (97-01).

No other light is on besides the ABS.

What year is the ES? I'll show you the instructions for getting the codes, if you have a 3ES.

ABS/Speed sensors.

No chance the breaks need to be replaced to fix the issue? And how much do the sensors cost? 1993 ES300.

Bump trying to get this fixed.

Replacing the brakes won't fix this issue. You will only see a BRAKE light, when your brake fluid dips below a certain level. An ABS light is completely different.

I don't have a reference for the 1993 model year, but this is what I used for my car. (1998)
Try it and see if it works, I doubt Lexus changed the system in those 5 years. Just so you know, I was able to read the codes with and without the Shorting Pin....not really sure which way is correct. Without the shorting pin, I was getting a bunch of different codes. With the shorting pin, and after resetting the computer, I was only reading one code.

p.s.: I just noticed that if your ABS light is ALWAYS on, then there might be a computer issue. Whenever I have my ABS light come on, it goes away after restarting the vehicle and only reappears under certain conditions.

The codes

So where will I see the number blinking again? I dont think there are numbers on the dash that blink.

The ABS light will flash multiple times, the frequency and the number of flashes indicates each digit. For example, 4 fast flashes, a pause, and 3 more fast flashes is number 43. If there are multiple codes, they will appear in a numerical order and then repeat.

Update: I just pulled a few ABS codes from my car. I noticed that the Shorting Pin makes no difference, I was still able to see the codes either way.

In order to erase/reset the memory, hit the brake pedal about 10 times in 3 seconds, the ABS light will start flashing rapidly if you do. (you have to be in the code reading mode to do this)

Did you travel through water puddle? I would check each ABS sensor on each wheel to see if wiring/sensor is damaged.

CELSIORAS

Check tyre pressure, check wires (from BCM ECU socket to all 4 sensors, check every sensor impendance, check each wire relative to the housing of chassis GND), Check U-Bat (12Volts) of BCM ECU (minimum 2 wires is 12 volts, one - direct from main battery, second - from Ignition Key). If no 12 (10.5-13.8) volts - check a bigest fusses. Check a brake fluid level and sensor.
If no reasons - go to local dealer, and coonect toyota tester or techstream for detail diagnostic procedure.
With Techstream - check errors, if no errors - try activations of Brake ECU components. Check ABS motor. Maybe its jammed. If the test is not success - new error will appears.

Also make sure that all of the tires are the same size.
