Depending on the make and model of car, the check engine light code to turn off the check engine light will vary. There are numerous websites explaining the proper procedure for turning off the check engine light. Other possible sources of information are the owner’s manual or an automobile repair manual. The dealer is also an excellent source. However, most dealers will require the car be brought into them for service, and applicable fees will apply. The majority of ‘service engine soon’ codes can be cleared using a hand-held scan tool or by disconnecting the battery. However, some cars will require the dealer reset the check engine light.
