Answers :

By getting the code, having them shut it off, and hoping it doesnt come back on. then saving your money in case the light did come back on. Alot of these will not turn off the MIL by disconnecting the battery. If you try you could loose navigation and codes for radio and the truck may have drivability issues till it relearns.
