Which is the right diagnostic scanner for my 95 Riviera...also how many pins does this model have on the computer connector inside the car...can I use an adapter? I was told my car has an obdII computer...with an obd1 connection type....not sure..

Your car is supposed to have a 16 pin connector. I would verify this visually.


It would also help to know the ID number on the PCM, guessing it is 16183247. Should be a sticker on the case...

Here is a link to a good thread on the subject:

OBD 1.5

Actually, what you have is an OBDII connector with an OBDI computer.

I have a '95 Corvette with the same "issue".
On the Corvette Forum's, I have read where it appears that both OBDI and OBDII codes can been thrown.
Not sure if this is true, or just urban legend.

I take my 'Vette to a local independent mechanic who has the correct OBD reader for these Mid 90's GM Model years.

The OBD1 connection has 12 pins, the OBD2 connection has 16 pins. My Auto X Ray scanner has capabilities to scan both. My scan tool is a good 10 years old though.

You have a OBD 1 computer and a OBD 2 connector, which has been called a "GM 1.5" at times, no it can't be done with a paperclip to pull codes. You need a scanner that clearly states it can read codes on this year GM vehicles.
