In addition to the other suggestions you have gotten, you can also test the individual ABS sensors at each corner. Follow the wire from the sensors on the wheel hubs to the connectors - in the front they are under the hood on the engine side of the wheel wells - for the back they are under the rear seat cushion.

Jack up the car and...
With a voltmeter on the AC setting (you need a voltmeter that can read AC, not DC)and connected across the terminals, you should should see some voltage when the wheel at that corner is spinning. This is because the sensor generates an AC voltage/current when the wheel is spinning, and its this voltage the ABS computer is looking for.

You should also NOT see a short circuit between the terminals of the connector to the sensor. A short circuit (no resistance in the sensor) would probably indicate a bad sensor as well.

I used this method to find a bad sensor once. Its easy once you find the connectors for the sensors...

Good Luck,

Mark
