Need to know how to turn off "service engine" light in a 2000 GMC 3500...?
Ever since we had the injection pump replaced, the "service engine" light comes on occasionally... 2000 GMC Savanna 3500 box truck, with 6.5 turbo diesel engine. I know there is a way, but do not remember how it is done...We had the pump replaced
you have to have this one done with a scanner to clear it off,anything you do other than that wont work,i own a repair shop,and do this 6 days a week,,the only true way is with a scanner to clear it off,good luck hope this help,s.,,PS auto zone will clear
