Where can I get my ECU code?

[Zoom_Zoom]

My maintenance light thingy is slowly turning from green to yellow, where can I get the code for this or whatever? I tried AutoValue and they don't have the computer for this car, its a 90 accord btw. Thanks

Maybe you need a tune up?

They have a key hole right on your dash...or at least my honda does.
You need to find your red key and stick it in there, then the light will turn green.
Or you could go and get your car tuned up and they'll do it for you.
