Another method used to clear codes is to turn the engine on and off three times in a row. Like the previous method, this method depends on experience, and you have to know what each code represents to know if this method will work or not. However, this method is safer because your vehicle is not in transit and only requires you to turn your engine on and off three times in a row. You can try this method by completing the on and off-cycle twice a row. Once you complete the process, you can wait a bit before turning on your engine to confirm if the light has disappeared. A good thing about this method is that you don’t require any tools to run the process.

A third method is to disconnect and reconnect the battery. To perform this task, you need a wrench to help you safely remove the battery terminals. While disconnecting the terminals, ensure they are not in contact with any metal. Please note that you must return each cable to the same point you removed it, and the negative line must go on to the negative terminus and vice versa. Placing the wires in the wrong terminals could lead to fires and other uncomfortable circumstances. After reconnecting the cables, be sure to tighten them properly with the aid of the wrench to avoid falling off.

The fourth method you could use to clear codes is an OBD code reader. The code reader tells you what each code represents. How do you reset your codes if all these methods don’t work? That’s where AutoZone comes into the conversation.
