OBD History
The Unites States Environmental Defense Agency (EPA) needed OBD to be standardized in 1996. Autos 1995 and previously use use diagnostic methods unique for their manufacturer.

You will discover scanners obtainable for these motor vehicles, but each automobile demands its have focused scanner. The question here is no matter whether or not it can be value purchasing a scanner in any way, as a result of their restricted use and performance.
Most OBD II scanners will not be reverse compatible. They will not be able to browse code from automobiles predating 1996.
