Buick Repair Questions? Ask a Mechanic for Answers ASAP
hello . how are you . Yes on that vehicle you can use a " code reader " type scan tool to clear Diagnostic Trouble Codes . However if you have an " active " code even selecting " Clear Codes " while you have the key on , engine off , will not necessarily turn the Mil light Off as the DTC is A " current " and " hard " code that will require a component or electrical or mechanical component to be repaired or replaced .
