Ferrari Mailing List: Re: Diagnostic Problem - 1995 348 Spyder

[Jim Conforti (lndshrk]

Dr. Steve:

You simply press the button on the affected ECU harness for
some specific time period (in engine state KOEO: Key On
Engine Off) which IIRC is 2.5 to 5 sec long.

The check engine lamp then flashes out a 4 digit code.

Or a series of 4 digit codes.

All codes start w/a 1, 2, or a 4.

example:

flash pause flash flash pause flash pause flash

would be 1211

The codes can be interpreted in a table in the manual
for your specific year of vehicle.

The 1995 should be equipped w/ M2.7 similar to the 95 F355.

PS: Once you've figured out the problem and fixed it - you
can clear the codes by holding the same button longer - I think
again (from memory) it's 10 sec or longer.
