Is there not a diagnostic socket & jumper lead under the bonnet on this year?
My '94 850 had one behind the drivers headlight.
If not, as others suggest, make a flash code reader, I used a 12v led from Maplins (gone now), you'll have to search to find which pins to use on the obd socket.
Sounds more complicated to say but it really is easy.
