Celica Forums General Discussion Exterior Engine light problem/ ECU code

My engine light came on after it had iced over for 3 days. The car runs fine, but the light is still on. Has anyone had a similar problem? How do I check the ECU code? Any information is greatly appreciated. Thanks.

why not reset the ECU by removing the ground wiring of the battery?

Thanks all. I reset the ECU, and the engine light has yet to come back on. I'm wondering if I could find an OBD2 scanner . . . my brother's ASE certified . . .

my cel is always on because of my o2 sensors. (its getting fixed, chill..) but anyways. one night after it iced over, my cel starting blinking! i was like wtf? so i let it warm up for like 20 min and it never stopped. so i drove home and checked the next morning and it stopped blinking.
