OBD question

I was under the impression that all cars 1996 and newer were OBD2. Is this true for the 96 'lude?

yes, your prelude is obd 2

what does obd2 mean, and whats obd1 and what does that mean as far as a car goes? anything i need to know about that? I also got a 96 Lude SI

OBD stands for OnBoard Diagnostics. In 1996 cars were switched over to a new version of the OBD (OBD2) in order to reduce emissions.

92-95=OBD1
96+=OBD2

OBD2 was also split into two sections, OBD2a and OBD2b. The split occured in 98-99ish, I can't remember off the top of my head.
