If the old Coil Pack was bad then likely you will need to have the error cleared from memory. the vehicle stores all faults like that which then require a tech to resolve the issue. I would go a little further and say that most scan tools that have the erase function on it should clear that particular code and make the light go off. In some rare occasions though I have seen the light go out but the code remain in memory. I would definitely recommend that you have the code removed as well as it can throw off a tech if you ever have another issue.
