1999 Ford Explorer Brake, ABS Problem
 

The ABS light came on while driving on the freeway. I checked the fuses, wiring, wheel sensors etc. I do not have an ABS scanner, can a meter be used at the test plug? How do you reset the ABS light? Anyone have information on this problem.

Hi nocal and welcome to the forum :)
You should probably take the Exploder in and get the ABS scanned to at least give you some idea of where to look for the problem. It takes a scan tool capable of reading ABS codes to retrieve them. Apparently the ones that Autozone uses arent capable of that.
To turn the light off you can disconnect a battery terminal for 10 minutes or so and that should clear it, until the next time the problem happens.

I found out the hard way. Every shop I have been to charges a $90-100 diagnostic fee and they usually 'throw in' the 1st 1/2hr labor ... last problem I had w/my 99 F250 LD I went and bought the OBDII code reader at the auto parts store. For $100 it diagnosed my exact problem and I saved hundreds on the repair PLUS I still have the code reader. Today I had an ABS light activation and, according to Chilton's, if I use the code reader while the light is on it will give me a trouble code. Chilton's even translates the codes in case your code reader doesn't.

If you are a DIY'er I would definitely invest in the code reader and work from there. Nothing bothers me more than paying a couple hundred bucks to have a sensor cleaned or something similarly simple.
