There's a clinker in yer thinker. Looks like you've been waiting for a few minutes so I'll stick my nose in here. You got codes 12 and 55. 12 just means the ignition switch was turned off and 55 is "end of message". If there's no other codes the Check Engine light will be off. If the light comes on while driving, be sure to not disconnect the battery as they will be erased and that valuable information will be lost.
