Okay on the 90 accord you lift up the carpet under the pass floorboard and there is a big metal plate, there is two led's that light up when checking the codes. Why are there two? What is the one on the right (towards door) for and what is the one on the left (towards console) for. They are both throwing codes. If the "S" light in the dash is throwing codes does that mean tranny problem codes? The check engine light is throwing one code a 7 and the tranny "S" light is throwing 5 codes, 1,2,6,7,14. Are these all engine codes? I did a search and came up with nothing. Please help me out.
