I have a 94 Prelude Si and the check engine light is coming on, usually in the mornings when its really cold outside. I am trying to get the code to figure out whats wrong but the ecu on this model is a little complicated. Here is a pic...

I read all over the place that all you have to do is short out 2 wires with a paperclip and it will spit out the code but I have no clue which wires to do and I dont want to screw up the computer...HELP!!?!

 

i dont know where that is on your car cause mine is a 5th gen..... but you should look near the obd2 connector thats where it is on a lot of them and it is usually a blue connector that you have to unclip, if it has two holes then put the paperclip in each hole with the ignition off, then turn the ignition on and it should throw the codes..... on my 5th gen its kinda in a tricky place, its on passenger side, on the column that touches where the shifter is right where the carpet is..... if you cant find it call the dealer and they can tell you where it is, but thats what it is supposed to look like, and if they cant tell you where it is let me know and I will call the dealer over here and find out lol....

 

my local honda dealership can't give me a straight answer....basically they want me to bring it in and they will look at it. **** that....im still looking for the connector.

 

lemme call the local dealership right now and ill try and find out where it is for you..... in the meantime, once we find where the connector is do you know what the codes mean and stuff like that? if not there is a site i can link you to with all the codes and what they mean etc..........

 

ok..... i called the dealership and they said on your car it is either located behind the ashtray...... or down on the passenger side on the lower right hand corner underneath that little plastic cover................ im going to email you with a page on how to do it and what the codes mean, im going to link you with the website k?

 

i tried sending it to your honda-acura address but it didnt work.... so if you still need it ill probably have to email it to your primary email address..... let me know what happens and if you were successful.........remember.... the connector you are looking for is usually blue and itll have two holes, and it will be plugged in so you have to unplug it and jump it with the paperclip.......hopefully you can find it......

 

Mine is behind the radio and ashtray. Prety easy t get to.

Good Luck

Tom

yup the ECU service connector is behind the ashtray. In my teg its right behind the glovebox to the right.
