My 93 Altima put out codes on the ECM but it appears my 95 doesn't. At least when I tried nothing happened.
Does anyone know what a scanner might cost and the manufacturer?

if youre able to go to autozone, have them do it for free.
did you happen to look up on your dash when you were looking for the codes? on the newer ecu's the check engine light is what flashing the codes - actually the older ones do too, but if i remember correctly, there isnt an led on the ecu on later models...
