My 92 Bonneville'* ABS is not working. Some time ago I went over a pot hole
and the ABS light turned on. I tested the brakes over dirt and ABS didn't
work. Otherwise brakes fine. For the next week or two sometimes the light
would go off and the system would work. Now it never works. I tested the
four weel sensors and all four send a signal. Any ideas on what may be
wrong?

Where is the computeter for the ABS system located?

Thank you

The EBCM is against the firewall, in the center of the car, a little to the passenger side.

You need a TECHII to diagnose this and should probably head to the dealer.

The computer for your ABS is just to the right of the gas pedal, behind the stereo on the firewall. Under the carpet. They rarely fail. In fact, I've never seen a single car here with one fail.

Your most likely suspect if your WSS are all good is the PMV assembly under your airbox. You need to go to a dealer to have the codes read to verify the problem and the failed component. This is far too expensive to be shotgunning parts.

Also make sure your wiring from the WSS is undamaged.
