My check engine light came on when my batteries went "dead". I replaced the batteries, starts just fine now but the check engine light is still on. How do I reset the computer so the light will go off without having to use a flash device thru a mechanic or something? I've seen procedures to cycle the ignition, etc that will do this for some vehicles. Can this be done on the 07 5.9L Cummins?
Thanks in advance.
