Yesterday, after the car was turned off, it started blinking d4 so, today I pulled the code using the paper clip trick, and I got what I think is code 18. Its a honda accord ex 1994, here is a youtube video of the code: http://www.youtube.com/watch?v=Ul9i6...ature=youtu.be

I mean I guess it could be 80 &10, 10&80 IDK it would make sense on the 80 and 10 though.
Thanks.

 

You will have to decipher the code on your own, resolution of the video for code reading is crap on youtube. I watched it three times and read 13 once, 8 another, and 22 the last. There are only 15 codes from the TCU.

A long blink is a count of ten, short blink is a count of one.
Codes will be displayed in numerical sequence, lowest to highest.
