Either use a scan tool from your local parts store, or just disconnect you negative battery terminal for about 5 minutes.

Do you have to disconnect the battery to replace number one coil


Disconnecting the battery is not the best idea as you may wipe out settings that you want. It is better to use a scan tool to delete the old codes. Auto parts stores can do it for free.

Replacing a coil can be done with the battery connected.
