Only OBD-II cars use a scan tool that plugs into the OBD-II port. OBD-II did not come out until 1996. Furthurmore, to my knowledge, the 2nd generation rx7's didn't use any form of OBD.
You got to use a OBD 2 code reader or scanner
A 96 Corsica uses OBD2 as required by law for 96 model years. Use an OBD2 Scanner.
plug it in and follow the directions
One that works with OBD II.
Yes you can OBD 2 reader/scanner are the only thing that will work to get codes
Obd1, obd2 wasn't until 1996.
OBD-1. 1995 was a changeover year. All 1995 cars/trucks (GM to my knowledge, I don't know about the other brands) were OBD-1 and some have an OBD-2 connector, but still are OBD-1.
Green coolant (prestone, etc)
Use an OBD code scanner to find out why the computer has turned on the check engine light.
No. Most heavy duty trucks and heavy equipment requires software for which an OBD scanner for light duty vehicles is not compatible, and usually also require an RP1210 Diagnostic Link Adapter.
Trouble code P0320 means:Ignition/distibutor engine speed input circuit malfunction. and you can use the Ford obd scanner to repair, you can DIY, it is easy.
