Hi cyclopsga,

The (some) 1995 and (all) 1996 model year Volvo automobiles come equipped with OBD-II with a data port to scan for codes and reset them after, presumably, the fault cause is repaired. OBD-II has change and evolved and is not an extensible messaging format.
So, what year 960 / S90 / V90?
The brickboard FAQ entry on OBD (copy and paste URL):
https://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm#OBDIIScanners
You mean this:
iCarsoft offers two OBD-II scanners
http://www.icarsoft.com/web/icarsoftus/allproducts/volvoscantools/index.html
You can find one on Amazon:
https://www.amazon.com/iCarsoft-VOL-Scanner-i906-II-version/dp/B010ODE03K
You will want to contact iCarsoft.
I'll guess this iCarsoft OBD-II reader provides the Volvo OBD-II fault code schema versus the generic ISO and industry standard of the time. Several new standards are in force with newer OBD-II messaging schemas may put some doubt whether the iCarsoft reader is 'fully backward compatible' with your model year 960 / S90 / V90. Volvo is not forthcoming with their side of the data port in messaging and message format for early and even current OBD-II.
The iCarsoft ad copy list support for OBDII-16 DLC. This specification is too new for your 960 / S90 / V90. While the messaging protcocol may be the same, the physical connection may not work for these two iCarsoft OBD-II code scanners for your model year Volvo auto.
Again, please see the OBD-II info link in the Volvo 700-900-90 series for your model year Volvo.
For generic OBD-II code reader you can use free at many auto parts store including AutoZone:
