I've been searching everywhere for what to do in this situation and i haven't come up with any good answers, hopefully someone here can lead me in the right direction.
My 93 Es300 has the ABS light constantly on. I've been driving it like this w/ no problems for about three years. Now i need to have an enhanced safety inspection in Pennsylvania and this needs fixed in order to pass. I've gone through some of the diagnostics and am coming up with trouble codes of 31,32, 35, and 36, which i believe is all of the wheel sensors. I'm sure that all of the sensors would not go bad at the same time. Where should i look next at diagnosing what needs to be repaired? Any help would be extremely GREAT!!!! Thanks!

Well, i replaced both front ABS Wheel sensors and finally after 3 years got the ABS light to go off.
NOW, when i'm slowing to a stop, right before the car stops, it seems like the brakes let go for a second and then pulsate until the car stops.

This happens when i'm braking fast or braking slow, and it only happens right before the car should stop. I never had this problem when the ABS system wasn't working. Is this normal; something i need to get used to; or could there be other problems????

After replacing these sensors, and the ABS light going off, TONIGHT, The light came on again after taking it for a short drive. I got codes 31 and 36 AGAIN. Where should i go next????

Have you looked at the rear sensors? Maybe there is some obvious corrosion or grime or something? It could even be a problem with the rotors that the sensor senses.

I haven't checked the rear because I keep getting a code for the front also. I noticed there is a code for the rotor, if the rotor was the issue, shouldn't I see that code, or is that not always the case?

I was just offering some suggestions, I would think if two codes went away after replacing two sensors it's a pretty good indication that two other things are amiss. But you should probably just look at everything, the problem could be visually obvious.

I have attached a copy of the abs codes, 35 & 36 could be a open in the front or rear sensors. When combined with 31 and 32 it would point to a open in the front circuit. Ohming out the harness from the controller to the sensor would be your best bet.
