93 240sx need to know how to read diagnostic codes...

[Glyph]

I have a 93 240sx vert and it's having major probs. The check engine light just came on and I'd like to read the error codes if possible. Is it? and if so how would I find out what they mean? Thanks for any help. -Glyph

try reseting the computer to see if the check engine light returns

and

here's one reference on how to read your trouble codes

plus,

a non-NICO link that says the same thing

ps, u can also download the FSM (in pdf file)
