How to reset the abs code light on a 2001 gmc siera 1500
Unhook your battery for 30+ Minutes. Then it should reset itself otherwise you will need a scan tool with ABS compatibility to reset it!
The ABS light will go out once the system is repaired correctly. Each time you start the truck the ABS system goes through a self diagnosis. If a problem is found the light remains on for that ignition cycle. Once you shut off the engine the ABS computer is cleared until you start it back up again. Then the self diagnosis repeats. Disconnecting the battery will do absolutely nothing. HTH. -Jim
