The anti-lock brake system (ABS) is controlled by its own computer. When it senses a problem, the ABS module on the dashboard will light up. When the problem is fixed, the module will sometimes still stay on, and it will need to be rest. This is an easy process, and takes a few minutes to complete.
Turn the vehicle off and put it into park. Apply the parking break, and turn the ignition switch to the "On" position, but do not start it.
Plug the connection cable that comes with the computerised scan tool into the bottom of the unit.
Locate the DLC connector found under the dashboard and just above the pedals. Plug the computerised scan tool into it and power on the scan tool.
Navigate to the "ABS" menu on the computerised scan tool by pushing the down arrow button. Select "Clear all codes."
Power off the computerised scan tool and disconnect it from the DLC connector. Turn on the vehicle and verify that the ABS module is no longer lit.
A computerised scan tool can be purchased online, or at any automotive supply store.
