In MOST cases making the repairs suggested or at least checking the connections (loose lamps show up as 'failures') will clear the codes from the DIC the next time you run the vehicle.
In other instances you may have to disconnect the negative battery cable, wait 5 minutes and hook it back up. Killing the static power from the battery will erase the computer codes and reset everything. The drawback is you also have to reprogram your radio if you have preset stations.
if this does not reset it, you have another bulb out, or a wiring problem...
