Can you use a ODB reader on a 1995 Honda Prelude Si?

Yes, you can use an OBD (On-Board Diagnostics) reader on a 1995 Honda Prelude Si, but it's important to note that this vehicle is equipped with OBD-I, not the more common OBD-II system found in cars produced after 1996. To read the diagnostic codes, you may need a specific OBD-I scanner or an adapter that can interface with the OBD-I system. Remember that the available data from OBD-I is more limited compared to OBD-II.
