To reset the computer codes on a 2001 Buick LeSabre, you can disconnect the negative battery cable and leave it off for about 15 minutes. This will clear the memory and reset the computer. After reconnecting the cable, start the vehicle to see if the check engine light is off. If the light persists, it may indicate an ongoing issue that needs to be addressed.
