Behind the glovebox, mounted to the inside of the firewall, there is a box with about 6-8 wires connected to it thru a connector. disconnect the connector for a minute or two, reconnect, and the ABS loght SHOULD go out - unless your problem is serious enough to just set the fault again immediately...
THEN, you can unplug the ABS sensor wheel at the top of the differential, install an 1800 ohm resistor across the wire harness to "fool" the 'puter into thinking everything is OK, and THAT may stop the warning light from coming on - but you do ALL this at YOUR OWN RISK!
